Meaning of extract: An extract is a concentrated preparation drawn from a plant, animal, or microorganism, used either as a medication itself or as an ingredient within one.

Definition of extract

An extract is a preparation made by drawing a particular substance out of its natural source, such as a plant, animal tissue, or microorganism, typically using a solvent such as water, alcohol, or oil. The process concentrates the compounds of interest while removing much of the surrounding bulk material.

Extracts are used in medicine and in dietary supplements in a range of forms, including liquids, tablets, and capsules, and the specific compounds present and their concentration can vary considerably depending on the plant part used, the extraction method, and the manufacturer.

Because an extract typically contains a mixture of compounds rather than a single purified substance, its effects can differ from those of an isolated active ingredient derived from the same source, and standardization of extracts, when it occurs, is intended to make the concentration of key compounds more consistent between batches.

Used in a sentence

Good to know
