摘　　要：通过试管和圆形滤纸预试法初步确定了牛心朴(Cynanchum komarovii)乙醇提取液中含有生物碱、酚类物质、鞣质、皂甙、黄酮、甾体(或萜类)、糖、多糖(或甙类)和强心甙等成分。杀鼠活性的测定结果表明,乙醇提取液在饵料中的含量为15％时,小白鼠的平均食毒量为39.04g／kg,对小白鼠的毒杀率为100％;饵料中牛心朴粉的含量为15％和10％时,小白鼠的平均食毒量分别为26.61 g／kg和29.27 g／kg,对小白鼠的毒杀率分别为100％和90％;提取液中的化学成分基本包括了牛心朴杀鼠的活性成分,且适口性较原粉为好。Chemical preliminary test shows that ethanal extract of Cynanchum komarovii in contains alkaloids, phenols , coumarins, saponins, flavonoids, sterol or triterpene, sugar, polysaccharides or glycosides and cardiac glyco-sides etc. Through the testing of rat killing activity, the result is abvious; when the content of liquid ethanal extract in the bait is 15% , the average poisons quantity that the rats eat is 39.04 g/kg, the killing rats to Mus musculus is 100% ; when the contents of the powder of C. komarovii are 15% and 10% , the average poisons quantity that the rats eat is 26.61 g/kg and 29.27 g/kg, the killing rates to testing musculus are 100% and 90% resqectively; the ethanol extract contains active constituents, and the edibility is also better than raw powder.
