光叶黄花化学成分研究(Ⅰ)——一种新生物碱的结构

Studies on Chemical Constituents of Thermopsis Licentiana(I)——The Structure of a New Alkaloid

光叶黄花（Thermopsis licentiana）是豆科野决明属植物,同属植物中有许多用以入药治疗狂犬病,该类植物的化学成分尚未见报道,为此,我们对其进行了研究,从中得到一种新生物碱晶A4并进行了分离与鉴定。

A new alkaloid was obtained from the ethanol extract of the whole part of thermopsis licen-tiana by using silica gel column chromatography. Its structure was established as 13-β-hydroxylther-mopsine by means of IR, MS, 13C NMR and DEPT, 13C-1H COSY, 1H-1H COSY technique.
