| 摘要: |
| 以粘虫幼虫为试虫，采用活性跟踪法，从砂地柏(Sabina vulgaris Ant．)果实中分离出2种二萜化合物，经MS，1H-NMR和13C-NMR鉴定为4-表-松香醛和7，13-松香二烯-3-酮。活性测试结果表明，0.005 g/mL 4-表-松香醛和7，13-松香二烯-3-酮对3龄粘虫均具有较强的拒食及一定的毒杀活性。 |

| Abstract: |
| With Mythimna separata Walker as the screening insect,two diterpenoids compounds were isolated from fruits of Sabina vulgaris Ant.According to the guidance of bioactivity assaying,their molecular structures were identified to be 4-epi-abietal and abieta-7,13-dien-3-one by MS,1H-NMR and 13C-NMR.The result of bioassay showed that 0.005 g/mL 4-epi-abietal and abieta-7,13-dien-3-one exhibited good antifeeding and some poisonous activity against the 3rd-instar Mythimna separata. |
