Abstract: The contents of the toxin 3-nitropropanoic acid in different varieties and morphology of Coronilla varia L.have been determined in this study.The results showed that the range of the contents of 3-nitropropanoic acid in Coronilla varia L.was 2.95% ~ 10.86% (dried base),and there were no remark able differences in the contents of 3-nitropropanoic acid among different morphology of Coronilla varia L.but there were some differances in the contents of 3-nitropropanoic acid among different varieties of Coro nilla varis L.Western Germany 2342 was higher (7.16%,dried base),American green gem and Canadian green gem were lower (5.93%and 5.74%,dried base).

摘要： 本研究测定了不同品种和形态特点多变小冠花(Coronilla varia L.)中毒性物质3-硝基丙酸的含量。结果指出:多变小冠花中3-硝基丙酸含量的变化幅度为2.95～10.86%(干物质基础),不同形态特点小冠花的3-硝基丙酸含量无显著差异,但不同品种小冠花的3-硝基丙酸含量有一定差异,西德品种2342较高(716%,干物质基础),美国品种绿宝石和加拿大品种绿宝石均较低(5.93%和5.74%,干物质基础)。
