对不同地区砂地柏各部位中脱氧鬼臼毒素的含量进行了测试 ,并以菜青虫为试虫测试了各样品的生物活性 ,初步探讨了脱氧鬼臼毒素含量与生物活性的关系。结果表明 ,各测试样品中都含有脱氧鬼臼毒素 0 .2 5～ 1 .40 mg/g。脱氧鬼臼毒素的含量与菜青虫的拒食率、死亡率之间无明显相关性 ,说明砂地柏组织中还含有其他具杀虫活性的成分。 The contents of deoxypodophyllotoxin in different parts of Sabina vulgaris were tested, and the bioactivity of each sample was tested by using Pieris rapae as test pest, and the relationship between deoxypodophyllotoxin and bioactivity was preliminarily discussed. The results showed that each test sample contains deoxypodophyllotoxin 0.25 ~ 1.40 mg / g. There was no significant correlation between the content of deoxypodophyllotoxin and the antifeedant rate and mortality of Pieris rapae, indicating that the Sabina przewalskii also contains other insecticidal active ingredients.
