摘要: 由我国东北产的苦参中分离出七种生物碱。由MS、IR及2D-NMR鉴定为:(+)-苦参碱、(+)-氧化苦参碱、5α-羟基苦参碱、N-甲基金雀儿碱、9α-羟基苦参碱及氧化槐根碱。另一个生物碱(6)的化学结构尚在鉴定之中。本课题采用了二种2D-NMR技术,H-H相关谱(300、400及500MHz)及C-H相关谱(H:300MHz;C:75MHz)。先发表其中两个生物碱的2D-NMR,其它将陆续发表。

Abstract: Seven alkaloids have been isolated from Sophora flavescens Ait, which has its origin in Northeast China. Six of these alkaloids have been positively identified by MS, IR and 2D-NMR. These are (+)-matrine (1), (+)-oxymatrine (2), (+)-5α-hydroxymatrine (3), (-)-N-methylcytisine (4), (+)-9α-hydroxymatrine (5), and (+)-oxysophocarpine (7). The structure of the other alkaloid (6) is currently being determined. Two types of 2D-NMR H-H COSY (500MHz, 400MHz or 300MHz)and C-H COSY (C:75MHz, H:300MHz) techniques have been used.
