摘要
测定了新疆若羌县苦豆子(Sophora alopecuroidesL.)植株不同器官部位总生物碱的含量及其对乳草蝽(Oncopeltus fasci-atus)的杀虫活性,结果表明:苦豆子生物碱在根、茎、叶、籽等不同器官均有分布,其根、茎、叶、籽中总生物碱的含量分别为:1.02%,0.51%,1.93%,2.55%;自根、茎、叶、籽提取的总生物碱对4龄乳草蝽若虫的触杀毒力LC50分别为:4.0344 mg/mL,3.5588mg/mL,11.739mg/mL,0.7155mg/mL。
Contents and insecticidal activity against Oncopeltusfasciatus of total alkaloids from different organs of Sophora alopecuroides L. in Ruoqiang county were investigated. The total alkaloids occurred in root, stem, leaf and seed of Sophora alopecuroides were yielded 1.02% , 0.51% , 1.93% , 2.55% and the LC50of them against the fourth stage nymphae were 4.0344 mg/mL, 3. 5588mg/mL, 11. 739mg/mL, 0.7155mg/mL respectively.
