小花棘豆(Oxytropis glabra D.C)为一广布于我国内蒙古及西北大部分地区的有毒植物。常为牲畜所误食。因而给内蒙古等地的畜牧业生产造成严重损失。该植物的有毒成分众说不一。有人认为,其毒性乃为含硒量过高所致。我们在确证其毒性部位为总生物碱的同时,对其含硒量也进行了原子荧光分析。
Oxytropis glabra D.C. is a poisonous plant widely distributed in Inner Mongolia and most of the northwest of China. Often eaten by livestock. As a result, the animal husbandry production in Inner Mongolia and other places caused serious losses. The toxic components of the plant are mixed. Some people think that its toxicity is caused by too high selenium content. When we confirmed that the site of toxicity was total alkaloids, we also conducted atomic fluorescence analysis of the selenium content.
