OBJECTIVE To investigate the cerebralvasorelaxant material basis of Xiaoxuming decoction.METHODS According to the Xiaoxuming decoction herb sources,we retrieved the chemical structure from the literatures and the Chinese Natural Product Database(http://pharmdata.ncmi.cn).By using microvessel tension system,we checked the vasorelaxanteffects of Xiaoxuming decoction anti-cerebral ischemia effective components group(XXMDECG)and the available composition compounds on pre-contracted basilar artery ring.RESULTS963 compoundsin the decoction,including 81Fangfeng,77 Mahuang,130 Shengjiang,31 Guizhi,91 Huangqin,127 Renshen,73 Chuanxiong,44 Shaoyao,39 Xingren,42 Fangji,62 Fuzi and 166 Gancao were collected.The five largest number classes of compounds in the decoction are volatile oil(32%),flavone(32%),alkaloid(13%),saponin(7%),polyphenol and organic acid(5%).XXMDECG at concentration from 1 to 400μg·mL-1can dilate the KCl(60 mmol·L-1)and ET-1(0.01μmol·L-1)pre-contracted rat basilar artery rings in a dose-dependent manner.There are 6 compounds with vasorelaxant ratio more than 50%at the concentration of 10μmol·L-1.CONCLUSION Xiaoxuming decoction contains abundant chemical structure.It has the material basis of multiple ingredients and multiple targets.The XXMDECG are able to dilate the rat basilar artery rings in a dose-dependent manner.The network interactions between varies of chemical compounds in Xiaoxuming decoction and the vasoconstriction associated targets result in the comprehensive regulation mechanisms of vascular function.
