A quotation for tongkat ali extract almost always carries a ratio: 50:1, 100:1 or 200:1. Some offers carry a marker figure instead, or as well. Buyers read the two as if one could be derived from the other, which is the source of most specification disputes in this material.
This article sets out what a ratio measures, what a marker measures, why the same material appears under different field names, and how to word a request so the answer cannot stay vague. It offers no arithmetic between the two, because none exists without the extraction record. Our tongkat ali extract ranges read in that order.
01 What 200:1 Actually Measures
The ratio is the most printed figure in the category and the least explained, so a tongkat ali extract specification needs one more question.
What does the ratio compare?
It compares masses: how much dried raw material went in against how much extract came out. A 200:1 material is one where a much larger quantity of root produced a single unit of powder. You will also see the claim written as 200 to 1, which is how most buyers type it. Either way it describes a yield relationship, not a composition.
What is left out of the ratio?
Everything about what the powder contains. The ratio says nothing about how much of any named compound survived the process, nothing about the solvent, nothing about the plant part, nothing about the markers present. Two producers can both achieve 200:1 and end up with different compositions, because the ratio records input against output, not what is inside the output.
02 Ratio and Marker Content Are Two Different Claims
Confusion begins because both figures are printed on the same tongkat ali extract sheet, in the same font, without saying they answer different questions.
What does the ratio claim assert?
It asserts a production relationship: this much material yielded this much extract. That is a statement about process, and it can be true of material with a wide range of compositions. A high ratio is a claim about concentration effort, and buyers often read it as a proxy for strength. The number does not support that inference.
What does a marker figure assert instead?
It asserts a measured content: how much of a named compound a stated method found in the lot as tested. Unlike the ratio it points at a property of the powder and can be checked by re-testing. Both claims can be accurate at once: a high ratio does not guarantee a high marker figure, and a high marker does not require a particular ratio.
| Figure on the sheet | What it describes | Can it be checked by re-testing? | What to ask for |
|---|---|---|---|
| Ratio, e.g. 200:1 | Mass of raw material against mass of extract | No, it is a production record | The extraction record behind the lot |
| Marker content | Amount of a named compound found by a method | Yes, on a retained sample | The method and its reference |
| Test method name | How the measurement was made, not what it found | Yes, by repeating the method | Whether it was run or only cited |
| Plant part | Which tissue the material came from | Partly, through authentication | A written declaration per lot |
| Ratio printed as specification | A field name that hides which claim is meant | Only after the question is put | Which claim the field is meant to carry |
03 Why the Same Material Appears Under Different Fields
Field names are set by whoever built the sheet, not by a common standard, so the same figure can appear in three places.
Why would one sheet print the ratio as the specification?
Because many buyers in this trade have always ordered by the ratio, so the field labelled specification ended up carrying it. On another sheet the same producer puts the ratio under extraction ratio and reserves specification for a marker. Neither layout is dishonest, and neither says which claim is being made until you read what the field contains.
What should a buyer do when the field names differ?
Ignore the label and read the content. A field carrying 200:1 makes a ratio claim whatever it is called; a field carrying a percentage of a named compound makes a marker claim. When comparing offers, line up the claims rather than the field names, and ask in writing for whichever claim is missing.
04 TLC and HPLC Do Not Answer the Same Question
The method line matters more here than in most categories, because a method named beside a ratio often does less work than buyers assume.
What does a TLC result establish?
Thin-layer chromatography separates components on a plate and lets an operator compare the pattern with a reference. It is useful for identity and for spotting a different material, and commonly runs alongside a ratio claim. It is not a quantitative determination, so a sheet pairing a ratio with TLC has not told you how much marker is present.
What does an HPLC result establish instead?
Liquid chromatography with detection can quantify a named compound against a standard, which is why marker figures are normally reported from it. A buyer who needs a marker figure needs a quantitative method named beside it; our guide to reading a certificate line by line applies the same test elsewhere.
05 What a Eurycomanone Figure Does and Does Not Tell You
Eurycomanone is the compound most often named on these sheets, and its figure is the one buyers compare first.
What does the figure confirm about the lot?
That the named method found the stated amount of that compound in the sample tested. It is a claim about one component at one moment, and it is enforceable if the method is named and the sample retained. Used this way it is a real specification, and can be written into a contract with a defined test clause.
What does it leave undetermined?
Everything else in the powder: other constituents, the plant part in practice, the ratio actually achieved, and behaviour in your process. A marker figure is a narrow, verifiable claim, and treating it as a summary of quality overstates what one compound can tell you. It also cannot be turned into a ratio, or a ratio into it.
06 Part Used: Root, Stem or Mixed Material
The plant part is a separate claim, and the one least often declared per lot.
Why does the plant part change the material?
Because different tissues carry different profiles, so material from one part is not interchangeable with another even at the same ratio and declared marker. A sheet saying only the root, without the species or the harvest, has told you less than it appears to. Our page on 200:1 tongkat ali powder declares the root as the part used, which is the level of detail to ask for.
How should the part be declared?
In writing, per lot, with the botanical name and enough harvest detail to make it checkable. Where material is blended across purchases, that should be stated rather than left implicit. A declaration that cannot be traced to a harvest is intent rather than specification, and the supplier verification process is where it gets tested.
07 Reading a Tongkat Ali COA Line by Line
A tongkat ali extract certificate releases a lot against a specification, and can only be compared with another certificate making the same claims.
Which lines let two lots be compared?
The material description with its botanical name, the plant part, whichever claim the sheet carries, the method with its reference, and the basis of any figure calculated on a dried basis. Where those align, two lots can sit side by side. Where the claims differ they are not comparable, whatever the headline figures suggest.
Which lines are routinely missing?
The plant part per lot, the extraction record behind a ratio, the method reference for a marker, and the basis of calculation. Our notes on bulk powder sourcing cover how that request is framed.
08 Writing an RFQ That Cannot Be Answered Loosely
Vague answers come from vague questions, and a ratio question is easy to answer with a ratio the buyer did not mean.
Which wording closes the ratio question?
Name the claim and the evidence: state that you require the extraction ratio, and separately require the extraction record supporting it for the lot supplied. Asking only for the ratio invites a number without a record, which cannot be verified after delivery. The words for the lot supplied keep the answer attached to the material you will receive.
Which wording closes the marker question?
Name the compound, the method and the acceptance basis in one sentence, then ask for the certificate for the lot to be shipped rather than a sample certificate. Separating the two questions makes the reply comparable, because a supplier answering both at once will often answer the easier one. Our overview of what this extract is covers the background a first-time buyer needs.
09 A Pre-PO Checklist for Tongkat Ali
Five questions settle most tongkat ali extract offers, all answerable before a purchase order exists.
Which five questions settle the offer?
- Which claim does this sheet carry, a ratio or a marker content?
- If a ratio, what extraction record supports it for this lot?
- If a marker, which method and reference produced the figure?
- Which plant part, declared per lot and with the botanical name?
- Which ratio options are actually available, since our pages list more than one and the order confirms it?
What should the sample confirm?
Confirm the appearance against the description, confirm the powder behaves as your process expects, and keep the certificate belonging to the sample's lot. Where the sample and the shipping lot differ, treat them as two lots and ask for both certificates.
10 Frequently Asked Questions
Is 200:1 the same as a eurycomanone percentage?
No. One records how much raw material produced the extract; the other records how much of a named compound a method found. No fixed arithmetic connects them, because the outcome depends on source material and process, not the ratio alone.
Which is better, a high ratio or a high marker figure?
Neither is better in the abstract, because they answer different questions. Choose the claim your specification can enforce and ask for the evidence behind it.
Can 50:1 and 200:1 be used interchangeably?
Only if the material behaves the same in your application, which the ratio alone cannot establish. Read a change of ratio as a change of material and qualify it on a sample, rather than adjusting the inclusion rate by assumption.
Why do two sheets list the same material differently?
Because field names are set by the sheet's author rather than by a shared standard. Read what each field contains rather than what it is called, and ask for whichever claim is missing before comparing.
What should I ask for before ordering?
The claim, the evidence behind it, the plant part per lot, and the certificate for the lot to be shipped. Add the classification the destination requires, requested with the shipping documents rather than taken from a listing.
