OBJECTIVE To establish the techniques for the extraction of corydalis B from Rhizoma Corydalis Yanhusuo. 目的建立测定白花土元胡药材中延胡索甲素和乙素含量的方法。
METHOD Orthogonal method was used to optimize the alcohol extraction techniques, with the soft extract derivation rate and the content of corydalis B and ammidin as the indexes. 方法应用正交设计以得膏率、延胡索乙素和欧前胡索含量等作指标综合评分对滴丸的醇提工艺进行优选。
Rotundine, corydalis B and berberine could inhibit writhing movements of mice and the inhibitory rate of rotundine, corydalis B, berberine, palmatine and coptisine is 98.4, 92.7, 40.8, 26.7, 11.0% respectively. 罗痛定、延胡索乙素、小檗碱、巴马汀及黄连碱对扭体反应的抑制率分别为98.4,92.7,40.8,26.7,11.0%。罗通定、延胡索乙素和小檗碱的作用有统计学差异。
