【摘要】 <正> 中药制剂成分复杂,且多数成分未知,因而定性、定量分析困难。事实上,多数情况下,不可能搞清中成药中每味药材的所有成分(也无此必要)。但生产及应用迫切需要内在质量标准。有些名牌中成药因无内在质量标准而影响出口。基于此因,我们系统研究了中成药的分析方法。本文介绍山豆根总碱注射剂的鉴别及定量方法。传统中成药(丸、散、膏、丹等)的分析方法将陆续发表。更多还原

【Abstract】 The identification of the components in the injection of root of Mensipermum Dahuricum DC by TLC and TLC-DM (Densitometry) has been discussed. This injection was found to contain 1-7mg/ml of Dauricine by reversed-phase ion-pair LC. Dauricin and Dauricinoline etc. were isolated from the total alkaloid of Menispermum Dahuricum DC by HPLC with silica gel G(10-10μm)as the stationary phase,and CHCl3-MeOH-NH3·H2O (100:5:0.35, V/V)as the mobile phase at a flow rate of 5ml/min. The pure components are identified by ATR-IR method.更多还原
