为探明灰毛豆Tephrosia purpurea种子中的杀虫成分及其对黑翅土白蚁Odontotermes formosanus工蚁成虫的杀虫活性,对其甲醇提取物采用多种色谱技术分离纯化,结合核磁共振图谱和质谱方法鉴定化合物的结构,并测定了各化合物对黑翅土白蚁工蚁成虫的触杀、忌避和传毒活性。从灰毛豆种子甲醇提取物中分离鉴定了10个化合物,即Obovatachalcone,Obovatin,异合生果素,鱼藤酮,Pongachin,12α-羟基鱼藤酮,6a,12a-脱氢灰叶酚,灰叶素,Penduletin和棉子糖。5个化合物(异合生果素,灰叶素,Obovatin,12α-羟基鱼藤酮和鱼藤酮)表现出触杀活性,处理后24 h的LD_(50)值分别为每虫93.9,123.5,209.1,259.4和370.8μg;3个...

In order to determine insecticidal compounds from the methanol extracts of Tephrosia purpurea seeds and their insecticidal activities against the adult of Odontotermes formosanus, active compounds were isolated with column chromatography and their structures were established by NMR spectroscopy, as well as by HR-MS analysis. Contact, repellent and transmission toxicities of each compound were determined against the adult of O. formosanus. Ten known compounds were isolated and identified (Obovatachalcone, Obovatin, Isolonchocarpin, Rotenone, Pon...
