Extract

 

a concentrated medicinal substance obtained from raw materials that contain certain active ingredients, such as glycosides, alkaloids, and vitamins; a type of galenical. Depending on the extracting agent used, extracts may be categorized as, for example, aqueous, alcoholic, or ethereal. Depending on the degree of thickening after evaporation, they may be classified as liquid, semiliquid (no more than 25 percent moisture), or dry (up to 5 percent moisture).
