What does an extract ratio like 10:1 mean?

Quick answer

An extract ratio compares the amount of plant material used with the amount of extract made. A 10:1 extract means about 10 g of dried plant went into each 1 g of extract. It describes the process, not the strength: the solvent, the plant's quality and any added excipients all change what the extract contains.1

Key facts

  • Most dry botanicals yield 10 to 25% extractable matter in water or water and alcohol, which works out to ratios between 10:1 and 4:1.1
  • A ratio is properly stated for the native extract, before carriers or other excipients are added.1
  • A high ratio can reflect a targeted extraction, or simply an extraction that left much of the material behind.1
  • For liquid extracts, FDA lets the label show the ratio of starting material to solvent, such as 1:5, and the final concentration if solvent is removed.2

How the ratio is worked out

Divide the weight of dried plant by the weight of extract it produced. If 100 kg of root yields 10 kg of dry extract, the ratio is 10:1. European medicines guidance calls this the drug to extract ratio, and the 2022 review we used calls it the plant to extract ratio.1

Natural variation means one lot of plant can yield more extract than the next, so makers often give a range rather than a single number.1

Why a bigger ratio is not automatically stronger

  • Solvent and method: water, alcohol and their mixtures pull out different compounds, and so do extraction time and temperature.1
  • Partial extraction: an extract that leaves much of the soluble matter behind can show a higher ratio without being richer in the compounds that matter.1
  • Excipients: carriers added after extraction dilute the extract, so the ratio of the finished ingredient can differ from the native one.1
  • Starting material: the quality of the plant going in limits what comes out.1

That is why the 2022 review recommends describing an extract by more than its ratio, including the solvent and, where possible, a chemical fingerprint.1

Ratios on supplement labels

FDA's rule for liquid extracts lets the label give the ratio of starting material to solvent, such as 1:5 in 70% ethanol. A dried extract is listed by the weight of the dried extract itself, so 500 mg of a 10:1 extract on a label means 500 mg of extract.2,3

If a label also gives an amount of a marker compound, that figure says more about what is in the extract than the ratio does.1,2

Questions people ask

Is a 20:1 extract twice as strong as a 10:1 extract?

Not necessarily. The ratio shows how much plant went in, but the solvent, the extraction method and any added carriers decide what is in the extract. Compare stated marker compound amounts, if the label gives them, rather than ratios alone.1
