摘 要:以牛皮消塊根為研究對象,用乙醇提取其活性物質(zhì),測試提取物對小菜蛾的觸殺活性,結果表明,提取物在濃度為50.00 mg/mL時(shí)對小菜蛾有一定觸殺活性,校正死亡率為83.33%。用溶劑萃取和柱層析分離,得到殺蟲(chóng)活性成分,經(jīng)結構鑒定,證明該化合物為β-谷甾醇。 |

Abstract:Insecticidal activity of ethanol extract from Cynanchi auriculati roots was tested against Plutella xylostella at the concentration of 50.00 mg/mL. The results showed that the corrected mortality of Plutella xylostella at 72 h was 83.33%. The structure of the extract was identified to be β-sitosterol. |
Key words:roots of Cynanchi auriculati;insecticidal activity;active component |
