Abstract

The invention relates to a chemical composition separation method of a traditional Chinese medicine smilax composition and a clinical application thereof. The method comprises the preparation of the water extractive extractum of the traditional Chinese medicine smilax composition, the ethyl acetate extraction of the water extractive material of the traditional Chinese medicine smilax composition,and the separation and measurement of the ethyl acetate extract by silicagel column chromatography. By the method, dihydro-kaempferol, dihydro-kaempferol 3-O-alpha-L-rhamnoside, and 3,3,5,5,7-pentahydroxy-flavanone 3-O-alpha-L-rhamnoside can be obtained, wherein the 3,3,5,5,7-pentahydroxy-flavanone 3-O-alpha-L-rhamnoside is separated from the smilax composition for the first time.

Description

technical field [0001] The invention belongs to a method for separating chemical components of medicinal plants, in particular to a method for separating chemical components of a traditional Chinese medicine sarsaparilla composition and its clinical application. Background technique [0002] The smilax composition is mainly prepared from the extract prepared from the Chinese medicinal materials sarsaparilla and smilax smilax through water extraction and alcohol precipitation, and appropriate amount of auxiliary materials. It is mainly used clinically to treat psoriasis; although it has been clinically used for many years and has good curative effect, its drug composition has not been very clear. [0003] Smilax (Smilax china L.) is the rhizome of Smilax genus Smilax in Liliaceae; (Smilax leaves are also used as medicine). [0004] According to prior art reports, Smilax root contains Smilaxin, Isoengeletin, Oleanolic acid, Kaempferide, Dihydrokaempferide, β -Sitosterol (β-S...
