川独活与东北独活的挥发油和薄层扫描比较

目的:比较独活的药典品种重齿毛当归(Angelica pubescens Maxim f.biserrata Shan et Yuan)(川独活)与在东北地区以独活代用品入药的兴安白芷(Angelica dahurica Benth etHook)(东北独活)的根及根茎中挥发油和香豆素类成分的差别。方法:分别采用气质联用法(GC—MS)和薄层扫描法(TLC—SC)。结果和结论:二者在挥发油的组成和香豆素的分类上均存在差别。从重齿毛当归中,共检出90种挥发油类,经计算机检索和与标准图谱对照,鉴定了其中52种。从兴安白芷中共检出57种,鉴定了其中37种。对以上两种植物的70%乙醇提取物进行薄层扫描比较,发现二者虽均以香豆素类为主,但川独活中主要为简单香豆素和二氢呋喃香豆素类,东北独活主要为呋喃香豆素。
