| 摘 要： | 对洱源丛枝瑚提取物进行了化学成分系统预试,结果表明其中含有甾体、萜类、挥发油、蒽醌类、香豆素类、氨基酸类、糖类等物质.测定了洱源丛枝瑚(Ramaria eryuanensis)子实体提取物的杀虫活性.结果表明,子实体提取物和乙酸乙酯萃取物对小菜蛾有较强的毒杀活性,石油醚萃取物对粘虫有较强毒杀活性.石油醚萃取物进行柱层析共得到15部分淋洗液,其中B1部分对粘虫有较强毒杀活性,72 h死亡率达到100%;B1、B2、B5、B6、B7部分对小菜蛾的毒杀活性较高,72 h死亡率均达到90%以上. |

| Abstract: | The chemical component of Rumuriu erynunensis include sterides,volatile oil, anthrayuinone,coumarin,amino acid and carbohydrate.The extracts of Rumuriu eryuaneusis were studied for their insecticidal activities.The bioasssy result showed that,the extract of fruitbody and ethyl acetate partition showed higher activities against Plutella xylostellu,the petroleum ether partition showed higher activities against Mythimna cepurutu.Consider the activities and content,the petroleum ether partition was separated by the silica gel column.15 fractions were collected,among which fraction B1 showed mortality to 10000 against M.separata,fraction B1,B2,135,B6 and B7 showed mortality up to 90% against P.xylostella. |
| Keywords: | Higher fungi Ramaria eryuurrensis Extract Chemical component Insecticidal activity |
