摘要

从马钱子(strychnobrasiline)的茎茎中分离得到一个新的马钱子碱衍生物- 12-羟基-10,11-二甲氧基马钱子碱1。通过光谱分析(1D和2D NMR、MS、IR、UV)和文献资料对比确定了其结构。另外两种已知的吲哚类生物碱，12-羟基-11-甲氧基马钱子巴西碱2和马钱子巴西碱3。

A New Strychnobrasiline Base of Strychnos Mattogrossensis

A new strychnobrasiline derivative, 12-hydroxy-10,11-dimethoxystrychnobrasiline 1 , has been isolated from the stem barks of Strychnos mattogrossensis . Its structure was established by spectroscopy analysis (1D and 2D NMR, MS, IR, UV) and literature data comparison. Two other known indoline alkaloids were also obtained from the heartwood, 12-hydroxy-11-methoxystrychnobrasiline 2 and strychnobrasiline 3 .
