The solution provides a method for separating a Chinese traditional medicine composition. To explain a pharmacological effect mechanism of a medicine made of two or more components and scientific content in rules of compatibilityamong components ofa compound medicine, systematic researches on the material basis is very necessary. Accordingly, deep researches are done on chemical components of the pharmaceutical composition in the solution, and eight compounds are separated, which areio-O-(p-hydroxycinnamoyl)-adoxosidic acid, aloe-emodin-8-O-β-D-glucopyranoside, quercitrin, matairesinol-4'-O-glucoside, liquiritinapioside, epi-vogeloside, vogeloside and ethyl caffeate, which provides a new quality control method for the composition in the solution.
