摘要： 对从砂地柏中分离得到的四个化合物鬼臼毒素、脱氧鬼臼毒素、4-表松香醛和7,13-松香二烯-3-酮的杀虫、抑菌及除草活性进行了初步测试。结果表明，4-表松香醛和7,13-松香二烯-3-酮对粘虫、小菜蛾及菜青虫等具有较强的拒食活性及一定的毒杀作用；鬼臼毒素和脱氧鬼臼毒素对辣椒疫霉、番茄灰霉及油菜菌核具有较好的抑制活性；除草活性研究表明鬼臼毒素对反枝苋、野燕麦根的抑制效果较强，脱氧鬼臼毒素对反枝苋、野燕麦及婆婆纳根的抑制效果较强，其抑制率均达到80％以上。

Abstract: This article conducted a preliminary test on the insecticidal, antibacterial and allelopathic activity of the four compounds——podophyllotoxin, deoxypodophyllotoxin, 4-epi-abietal and abieta-7,13-dien-3-one that isolated from Sabina vulgaris Ant. The results showed that 4-epi-abietal and abieta-7,13-dien-3-one had strong antifeeding activity and certain toxicity against Mythimna separata Walker, Plutella xylostella Linnaeus and Pieris rapae L.. And podophyllotoxin and deoxy podophyllotoxin exhibited good antibacterial activity against Phytophthora capsici Leon, Botrytis cirerea Pers. and Sclerotinia sclerotiorum (Lib.) de Bary. Allelopathic activity showed that podophyllotoxin against root of A.retroflexus.L. and Avena fatua , deoxypodophyllotoxin against root of A.retroflexus.L., Avena fatua and Veronica persica had good inhibition effect, the inhibating rates were more than 80%.
