Total Mogrosides vs. Mogroside V: How to Compare Specifications

Monk fruit extractPublished by Guilin Hengliyuan Biotech

Compare Mogroside V with total mogrosides, evaluate 25% and 50% extracts, read assay and COA results, and check grade changes in your food or beverage.

Mogroside V is a sweet cucurbitane triterpene glycoside found in monk fruit (Siraitia grosvenorii). It is one constituent of total mogrosides, not another name for the whole extract. A 50% Mogroside V extract, a 50% total-mogrosides extract and a high-purity laboratory standard describe different materials.

Buyers should not compare “50% total mogrosides” with “50% mogroside V” as if they were the same grade. Across suppliers, first align the measured constituent, test method and reporting basis, product form and carrier, sample reference and matching batch COA. Then compare quotations and results from trials in the intended application.

What is Mogroside V, and what does its name identify?

The V is the Roman numeral five. The individual compound has CAS 88901-36-4 and molecular formula C60H102O29; its molecular weight is approximately 1287.4 g/mol. These identifiers describe the molecule. A commercial monk fruit extract also contains other constituents, so the same marker CAS on two sales sheets does not establish identical composition or suitability for food use.

Description on the offerWhat you are comparingFirst document to check
Mogroside V assay, e.g. at least 25% or 50%The named constituent in a supplied extractGrade specification, assay basis, full ingredients and selected-lot COA
Total mogrosides, e.g. 80%A method-defined combined measureWhich compounds or equivalent responses the method includes
Extract ratio, e.g. 10:1A stated starting-material-to-extract ratioRatio definition, process and separate assay; it is not 10% Mogroside V
Mogroside V analytical reference standardA laboratory calibration or identification materialIntended-use statement and the standard’s own certificate; it is not a food formulation ingredient

For example, FUJIFILM Wako lists a 95.0+% HPLC Mogroside V standard in a 50 mg format for food analysis and labels it for research use. Its analytical purpose does not become an edible-ingredient approval because the word “food” appears in “food analysis.”

What else is included in total mogrosides besides mogroside V?

Total mogrosides is not a single substance, but the sum of several mogrosides. Mogroside V, often abbreviated as MV, is just one of them. Other representative constituents reported in monk fruit and its extracts include:

ConstituentEnglish name
Mogroside III and related constituents, such as mogroside IIIEMogroside III, Mogroside IIIE
Mogroside IVMogroside IV
Mogroside VIMogroside VI
Siamenoside ISiamenoside I
11-oxo-mogroside V11-oxo-mogroside V
Isomogroside VIsomogroside V

The relationship can therefore be understood as follows: total mogrosides is a combined measure covering mogroside V and other mogrosides; mogroside V is one individual measure within that group. These are representative constituents, not a fixed formula with identical proportions in every extract, nor a complete list used by every total-mogrosides assay. Check the relevant analytical method and report to establish which constituents are included for a particular product. Constituent names are based on the public FDA GRN 629 submission, a comparative study of differently dried monk fruit products, and EFSA information on monk fruit extract composition. These sources explain constituent names; they do not represent measured results for any Hengliyuan batch. GRN 629 is a historical submitted dossier; its FDA evaluation was subsequently ceased at the notifier’s request. Its use here is limited to constituent identification, not proof of market authorization.

Why is 50% total mogrosides not the same as 50% mogroside V?

“50% total mogrosides” means that the mogrosides included under the relevant assay total 50%. The proportion of mogroside V must be checked in its individual test result; it cannot simply be assumed to be 50%. “50% mogroside V” means that this one constituent accounts for 50%. Other mogrosides may also be present, so it cannot be assumed that total mogrosides is only 50%.

Specification wordingWhat the percentage meansWhat cannot be directly concluded
50% total mogrosidesThe combined content of the mogrosides included in the assay is 50%Mogroside V also reaches 50%
50% mogroside VThe content of mogroside V alone is 50%Total mogrosides is only 50%, or no other mogrosides are present

These figures explain the distinction between measures; they are not test results for a particular batch. On a real COA, also distinguish a specification limit such as “≥50%” from the measured batch result. The specification column states the requirement; it is not automatically the numerical result for that lot.

Five-batch composition data show what a grade number leaves out

EFSA’s 2019 assessment reports applicant-submitted composition results from five batches of each of five extract grades. In the named 25% grade, measured Mogroside V ranged from 25.96% to 26.53%; in the named 50% grade, it ranged from 51.03% to 51.81%. The stated grade and the actual batch result were different numbers. Other constituents also changed across the submitted extracts.

25%25.96–26.534.98–5.24
40%40.95–41.956.36–6.56
45%46.11–46.828.52–8.72

Reported Mogroside V and 11-oxo-mogroside V content ranges in five historical extract grades, with five batches per grade; separate panels use different zero-based scales.
Source: EFSA Journal 2019, 17(12):5921, Table 1. Each line shows a reported five-batch low–high range, not a confidence interval; the panels use different scales. These applicant-submitted data illustrate composition differences and do not establish Hengliyuan specifications, sweetness superiority or safety.

These are historical submitted composition data, not universal grade requirements, Hengliyuan test results or a taste comparison. The ranges are not means, standard deviations or confidence intervals. Do not sum the separate lower or upper bounds to reconstruct one batch: the table does not identify which component results occurred together. A higher Mogroside V percentage alone also does not establish better sensory performance.

Equal total-mogrosides content can still mean different compositions

Even when two ingredients have the same total-mogrosides content, their proportions of mogroside V and other mogrosides may differ. The total percentage alone does not establish identical composition. Likewise, equal mogroside V content does not mean that other constituents and all product parameters are identical. Compare the full specifications and batch-specific test documents, rather than just one number on a quotation. Customers who require a defined mogroside V content should request that measure explicitly. If total mogrosides is required, specify the assay requirements. Hengliyuan can help confirm specifications against the measures the customer actually needs. The fraction outside Mogroside V is not automatically maltodextrin, another added carrier or waste. It can include other native constituents. Ask for the complete composition and carrier declaration; do not infer the answer from 100 minus the V percentage. Likewise, a marker assay does not establish the full nutritional composition.

HPLC, UV and peak area: ask what the percentage measures

HPLC separates compounds; UV can describe a detector or a different assay approach. “HPLC-UV” is a valid combined description, so it is misleading to treat every mention of UV as automatically inferior to HPLC. What matters is whether the method identifies and quantifies the requested constituent or defined total with a suitable reference standard.

Result or method wordingWhat to resolve before comparing
Mogroside V by HPLCMethod reference/version, identification, calibration standard, calculation and reporting basis
Total mogrosides by UVAssay procedure, reference compound and whether the result is expressed as an equivalent response
Total mogrosides by chromatographyNamed included peaks, calibration/response treatment and summation rules
Chromatographic area purityWhether water, solvents and non-detected material are excluded from the denominator; do not automatically read it as mass fraction
Conforms or passesThe accepted limit and method; request a numerical result where the buying decision requires one
Finished-food assayMatrix recovery and sample preparation for that food; an extract method alone does not establish a finished-drink method

There is a useful real document example: PhytoLab’s public example certificate for Mogroside V reference substance 80498 lists HPLC area purity as 100.00% and calculated content as 98%. The certificate explains that water, residual solvents and inorganic impurities enter its mass-balance calculation, and quantitative calculations should use absolute purity rather than area purity alone. This is an analytical-standard example, not a COA for edible monk fruit extract. Its “Example only” label must stay with the example.

As supplied or dry basis: a 50% result needs a denominator

A percentage is incomplete until its basis is clear. Ask whether the result applies to the material as supplied, dry matter or another specified basis. Moisture and loss on drying are not automatically interchangeable: loss on drying can include substances other than water, depending on the method.

Explicitly hypothetical exampleCalculationMeaning
50.0% Mogroside V on a dry basis; 4.0% moisture by a compatible method0.500 × (1 − 0.040) = 0.48048.0% in the as-supplied material under those assumptions
48.0% as supplied; the same 4.0% moisture0.480 ÷ 0.960 = 0.50050.0% on that dry basis
A separate document only says “loss on drying ≤5%”No measured moisture or agreed correction basisDo not silently replace the lot’s result with a calculated dry-basis number

These are denominator examples, not batch data. A listed maximum moisture limit is also different from the measured moisture of the lot. If two laboratories disagree, have them compare the same retained sample, method, reference-standard correction and reporting basis before treating the difference as evidence of adulteration or a grade failure.

Read the COA as a batch record

Check the product identity, grade, batch number and report date together. Separate the specification limit, actual result and method reference; a generic specification sheet describes a product requirement, while the batch COA reports the identified lot. Confirm the manufacturer and COA issuer for the material being supplied. For the assay, request the measured constituent, method reference or version and reporting basis. The word HPLC alone does not establish that two reports use the same procedure. Ask whether the percentage is reported on the supplied material, a dry basis or another stated basis, and clarify the relevant moisture or drying result before making any correction. Do not silently compare different bases as if they were identical. Keep the evaluated sample code and lot with its COA. If the proposed supply lot differs, confirm the applicable batch documents and whether the change requires another application check. A favorable sample result describes the material tested; it does not identify every later supply lot. For purchasing, separate specification approval, sample acceptance and release of the actual supply lot. Request any required document before the stage where its absence would block the decision; do not wait until shipment to discover that the promised material lacks the agreed assay basis.

Four public supply examples: compare documents rather than grade names

Public supplier documents make the comparison concrete. The examples below belong to the named suppliers, not to Hengliyuan; their packaging, limits and availability do not establish our offer.

Original supplier exampleUseful information actually providedWhat still needs confirmation
Monk Fruit Corp MFC-E25P and MFC-E50Separate 25% and 50% Mogroside V product identities, alongside other gradesCurrent full specification, lot results and performance in your base; a grade list is not a controlled taste trial
Total Ingredients THX1871, March 2026 specificationMogroside V at least 25.0% by HPLC, moisture at most 5.0%, and at least 95% passing 80 meshA supplied-lot COA and full method/basis; a specification limit is not the actual assay result
MarkNature 80% total-mogrosides listingThe same specification also names Mogroside V at least 30%80% total and 30% V are different measures on one offer, not interchangeable purity claims
TR Nutritionals 50% extract specification, revision December 20, 2017A named HPLC assay of at least 50.0%, particle analysis and bulk-density informationWhether that historical revision remains applicable to the material currently offered; request the current controlled document

Notice how “80 mesh” can hide different acceptance wording, and how a dated specification can remain easy to find long after its issue. Keep the document version, issuer, sample identity and order lot together. A website table headed “COA result” without a traceable lot and report date is not enough to identify your shipment.

A formulator case: a blend is a different comparison from a purer extract

In a July 15, 2025 technical comparison, Icon Foods describes its MonkSweet LS4 as a blend of monk fruit extract and Reb M stevia, contrasted with V25, V40 and V50 extracts. Its comparison table describes LS4 as containing less than 10% Mogroside V plus steviol glycosides. This is a useful illustration of why the highest V percentage is not the only way to develop a sweetener system.

The article’s sensory and efficiency conclusions are the supplier’s claims. The displayed comparison does not provide a full sensory protocol, panel size, tested concentrations or uncertainty with which to reproduce a universal ranking. Its table and bar chart also give different sweetness numbers for V25 and V40, so we do not use those graphics as a dose calculator. For your project, identify every sweetener in the system and compare actual taste-approved use levels, label requirements and cost in the same base. A blended system cannot be treated as a single-variable purity trial.

Switching 25% to 50%: what the mass calculation can establish

If both results are measured on the same as-supplied mass basis, you can first match the amount of Mogroside V. The relationship is extract mass × assay fraction = Mogroside V mass. This is a bookkeeping starting point for a trial, not a sensory substitution rule.

Hypothetical 100 kg final batch25.0% extract50.0% extract
Supplied extract added100 g50 g
Mogroside V mass100 g × 0.25 = 25 g50 g × 0.50 = 25 g
Supplied extract concentration1,000 mg/kg (0.10%)500 mg/kg (0.05%)
Mogroside V concentration250 mg/kg250 mg/kg

Both calculations assume a 100 kg final mass, so adjust the rest of the formula to keep that denominator unchanged. The changed extract mass, other mogrosides and accompanying components are not identical; equal Mogroside V mass does not prove equal sweetness, aftertaste, color or solubility. Keep the sample identity, concentration basis and complete formula with each result. A concentrated extract also does not replace sugar’s bulk, water contribution, freezing-point effect or browning behavior at the same spoonful. Where sugar is removed, evaluate those functions separately. The example use levels above are chosen only to show the arithmetic, not recommended doses or permitted-use limits.

Changes in content affect taste as well as sweetness

When helping customers select ingredients, Hengliyuan does not recommend choosing an extract solely by its content level. A change in content changes taste as well as sweetness. When switching specifications, do more than recalculate dosage: compare samples in the actual food or beverage to confirm that the overall taste meets requirements. Content figures help describe an ingredient, but do not replace application trials. If your current product does not taste as expected, tell us its specification, intended use and what you want to improve. Hengliyuan can suggest selection and adjustment options, which can then be checked through practical trials.

Compare the grades in the product you intend to sell

Set a reference sweetness in the complete base, then compare candidate grades at adjusted doses. Keep acidity, other sweeteners, flavors, solids, temperature and process fixed wherever possible. Record sweetness onset, intensity, linger and unwanted notes separately; a single “better taste” score hides the reason for the choice.

ApplicationWhat to hold and recordWhat the assay alone cannot answer
Clear acidified beverageBase and pH, addition order, dissolution, actual heat process, clarity/color and taste at serving temperatureWhether haze, color or aftertaste will remain acceptable after processing and storage
Dairy or plant-protein drinkProtein/fat system, flavors, processing, equal-sweetness target and chilled/ambient evaluationWhether the grade masks or emphasizes the base’s bitterness and astringency
Dry drink mix or sachetCarrier and complete blend, weighing/premix sequence, particle distribution and reconstitutionWhether a small dose is evenly distributed or settles during handling
Bakery or frozen dessertThe entire sweetener/bulking system, water, solids and process, followed by cooled or frozen product assessmentWhether matching sweetness also preserves texture, yield and shelf-life performance

For a change in grade, retain both an assay-matched comparison and a taste-adjusted comparison when useful. The first helps isolate composition questions; the second determines the use level needed for the product brief. Neither turns a small internal trial into a published customer case or a universal ranking of 25% versus 50%.

Keep stability claims tied to the tested material and conditions

EFSA’s 2019 assessment describes several different stability submissions. A 55% extract lost less than 3% Mogroside V after three months at 37°C and 75 ± 5% relative humidity, and after twelve months at 25°C and 60 ± 10% relative humidity. A separate 25% extract model was not stable at pH 1, while tests at pH 3, 6 and 12 covered four weeks at 2–8°C. These are not interchangeable storage protocols.

The assessment states that no finished-food stability data were provided in that submission. It also describes thermal model tests, which do not make every drink, baking process or shelf life validated. Ask for the selected grade’s storage conditions and package, then check the actual product’s heat exposure, pH, packaging and required life. An unchanged Mogroside V assay alone does not establish unchanged flavor, microbiological quality or commercial shelf life.

A specification or a GRAS notice number is not market approval

For a US food project, match the material’s identity, manufacturing process, composition and intended use with the applicable regulatory basis. Do not use “FDA approved” as shorthand for a supplier’s GRAS position or for a filed notice. Food use, dietary-supplement use and laboratory use are separate decisions.

The GRN 629 submission linked in the constituent discussion is useful as a historical technical dossier. FDA’s response, dated August 9, 2016, says the notifier withdrew it to change product profiles and specifications, and FDA ceased evaluation effective July 15, 2016. It is therefore not a “no questions” letter for that notice. A table inside the submission does not override the response letter. Likewise, EFSA’s 2019 composition tables are not an authorization for those grades; that assessment concluded the submitted toxicity database was insufficient to conclude on safety for the proposed additive use. Use the data here for the stated technical comparison and confirm current destination-market status separately for the exact material. A buyer’s intended use cannot be approved from the Mogroside V percentage alone.

When two reports or samples disagree, choose the next check

Use the difference to select a controlled comparison. Avoid changing the grade, carrier, dose and flavor system together and then attributing the outcome to one assay number.

Observed differenceNext check
48% on one report and 50% on anotherAs-supplied/dry basis, measured moisture, standard correction, method and sample identity
Same V result, different taste or colorOther composition, carrier/process history, equal-sweetness dose and full-base comparison

Good bench sample, inconsistent dry production blendPremix dilution, mixing uniformity, segregation and retained samples from the actual run
Stored material changes or clumpsSeal/package history, humidity, storage and selected-lot retest; do not infer shelf-life extension from a single passing assay

Compare quotations after aligning the material

First align the analyte, method and reporting basis, product form, carrier declaration, specification and relevant batch/sample reference. Then compare currency, quotation date, pack size, quantity, delivery terms and the costs included in the offer. A lower price per kilogram is not an application-cost comparison when the materials require different tested use levels. Do not calculate the inclusion rate from assay alone and call the taste equivalent. Keep the matched application result with the cost discussion. The existing cost-in-use guide explains how to compare the complete ingredient system at its intended use level. For a deliberately hypothetical chemistry-only comparison, USD 80/kg ÷ 0.25 = USD 320 per kg of Mogroside V, while USD 140/kg ÷ 0.50 = USD 280. Those are invented prices and a constituent-cost calculation, not quotations or proof of cheaper sweetening. In the illustrative 100 kg batch above, the extract costs would be USD 8 and USD 7 respectively; if the taste-approved doses differ, recalculate from those actual use levels and include delivery, waste and rejected output. The lower assay-normalized cost need not be the lower cost of an acceptable product.

Hengliyuan offers multiple specifications and customization

Hengliyuan offers monk fruit extracts at various content levels and can discuss customization to customer requirements. The current product page lists a 50% mogroside V sample reference and a 20%–60% range for content requests. Customers who already know their targets can state their specific mogroside V or total-mogrosides requirements. Those who have not selected a specification can describe the intended use and taste requirements so we can help choose samples. Before placing a purchase order, confirm the analytical parameters, methods, content calculation basis, specification sheet and COA for the supplied batch. Available specifications and current stock are confirmed separately; packaging, quantity and lead time are discussed for the order.

Common questions

Is mogroside V part of total mogrosides?

Yes. The existing constituent table lists representative mogrosides. Which constituents are included in a particular total-mogrosides result depends on the analytical method and report; the table is not a fixed composition for every extract.

Discuss this request
Can total-mogrosides content be converted directly to mogroside V content?

Not from the total percentage alone. You need the individual mogroside V result or an appropriately determined composition under the relevant method. Do not relabel total mogrosides as Mogroside V on a purchase sheet.

Discuss this request
Why can two ingredients both marked 50% differ?

Check whether 50% refers to total mogrosides or Mogroside V, and whether it is a stated limit or a batch result. Align the method, reporting basis, product form, carrier and other requirements before comparing quotations.

Discuss this request
Does a specification of at least 50% mean the batch tested exactly 50%?

No. A minimum requirement and a measured batch result are different entries. Read the result for the identified lot and confirm the method and basis used.

Discuss this request
Should the evaluated sample and supply batch have the same reference?

Keep both references traceable. If the supply lot changes, confirm its batch documents and decide whether the application check needs to be repeated. Do not attach a sample result to an unidentified later lot.

Discuss this request
Can Hengliyuan discuss customized content levels?

Yes. Send the requested Mogroside V or total-mogrosides measure, application and target market. We will check the matching specification, documents and sample options for the actual material; current availability and order terms are confirmed separately.

Discuss this request
Is Mogroside V the same as monk fruit extract?

No. It is one named constituent. The extract is a mixture; its full composition, assay and intended use still need to be identified. A laboratory standard is a different supplied material.

Discuss this request
Can I halve the dose when switching from 25% to 50% Mogroside V?

Halving the mass matches Mogroside V only when the assay fractions and reporting bases support that calculation. It does not establish equal taste or finished-product behavior. Adjust and test the complete formulation.

Discuss this request
Does 100% HPLC area mean 100% Mogroside V by mass?

Not automatically. Area purity and absolute mass content can differ because water, solvents or other components may not enter the area calculation. Use the identified method and the reference standard’s certified correction.

Discuss this request
Can I compare dry-basis and as-supplied assay results directly?

First reconcile their denominators with the measured moisture and agreed method. A maximum loss-on-drying limit alone is not the lot-specific moisture correction.

Discuss this request
Does a higher Mogroside V grade always taste better?

The assay describes one constituent. Compare the grades at appropriate doses in your actual base, including onset, linger, unwanted notes, color and process stability. Higher content is not a universal sensory ranking.

Discuss this request
Does GRN 629 prove FDA issued a no-questions letter?

No. FDA’s August 9, 2016 response says the notifier withdrew GRN 629 to change profiles and specifications and the agency ceased evaluation. Read the actual response and verify the applicable basis for the proposed material and use.
