Un extrait 10:1 et un extrait à 95 % ne décrivent pas la même chose. Comment lire chaque spécification, comparer les offres équitablement et choisir la bonne pour votre formule.

When two suppliers quote "reishi extract", they may be offering very different materials. One lists 10:1, the other 30% polysaccharides. Both descriptions can be correct, but they answer different questions, and comparing them on price per kilo alone leads to poor buying decisions.
A ratio, also called the drug-extract ratio (DER), states how much dried plant material was used to make one part of extract. 10:1 means roughly 10 kg of raw material for 1 kg of extract.
It describes the process, not the content. Two 10:1 extracts can contain very different amounts of active compounds, depending on the plant part, the solvent and the raw material itself.
Before accepting a ratio specification, ask three questions:
A standardised extract guarantees a minimum content of a defined marker compound, for example 80% silymarin or 95% curcuminoids. This makes the amount per serving predictable from lot to lot, which is why most capsule and tablet formulas specify standardised grades.
The same material can give different figures depending on the method. UV spectrophotometry measures a broad group of compounds, while HPLC quantifies specific ones. That is why extrait de chardon-marie is commonly offered both as 80% silymarin by UV and around 30% by HPLC. These figures do not necessarily describe different qualities.
Spécification | Ce qu'il garantit | Usage typique |
|---|---|---|
Ratio (e.g. 10:1) | Concentration de l'extrait par rapport à la matière première | Labels that declare the dried-material equivalent |
Standardised by HPLC | Teneur minimale en composés marqueurs individuels | Formules où le marqueur par portion doit rester constant |
Standardised by UV | Teneur minimale d'un groupe de composés | Groupes tels que les polysaccharides ou les polyphénols |
A quick calculation helps: if your formula needs 475 mg of curcuminoids per serving, that is 500 mg of a 95% turmeric extract. You can test combinations like this in our calculateur de formules.
The cheapest kilo is not always the cheapest serving.
