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 compatibility among components of a 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 are 10-O-(p-hydroxycinnamoyl)-adoxosidic acid, aloe-emodin-8-O-β-D-glucopyranoside, quercitrin, matairesinol-4′-O-glucoside, liquiritin apioside, epi-vogeloside, vogeloside and ethyl caffeate, which provides a new quality control method for the composition in the solution.
