假败酱(Stachytarpheta indica Vahl.)外用可治疗化脓性溃疡,风湿性炎症,高热及赤痢。也有报导可用于治疗癌症。本文对其叶进行了化学研究。将五月份收集的阴干叶子,先用氯仿提取,继用纯制乙醇回流提取。将氯仿浓缩液通过氧化铝柱层析,用石油醚、苯和氯仿连续洗脱,从石油醚洗脱液,得胡罗卜素烃类化合物及低熔点烃类;用石油醚-苯(10:1)洗脱,得无色固体,熔点258～260°,经混合熔点等测定,证明为无覊萜,用石油醚-苯(1:1)洗
Stachytarpheta indica Vahl. Topical for the treatment of purulent ulcer, rheumatic inflammation, fever and dysentery. There are also reports that can be used to treat cancer. This paper carried out a chemical study of its leaves. The dry leaves collected in May, first extracted with chloroform, followed by pure ethanol reflux extraction. The chloroform concentrate was subjected to column chromatography on alumina and eluted successively with petroleum ether, benzene and chloroform to obtain carotenoid hydrocarbons and low-melting-point hydrocarbons from petroleum ether eluent; petroleum ether-benzene (10 : 1) eluted to give a colorless solid, mp 258-260 °, determined by mixing melting point, etc., proved to be unimodal, washed with petroleum ether - benzene (1: 1)
