| Abstract: |
| 【Objective】 This study is to determine the killing active sites of 8 plants to Dactylogyrus.【Method】 The 8 plants with killing activity to Dactylogyrus were extracted by using petroleum ether,chloroform,acetone,acetic ether,ethanol,N-butanol and water.Then the killing activties of those extractions were tested.【Result】 The results showed that the chloroform extracts of Datura.metel L.,Macleaya cordata,Cnidium monnieri(L).Cuss.and Ginkgo biloba L have a better activity to control Dactylogyrus,the petroleum ether extracts of Brucea javanica(L.) Merr.and Macleaya microcarpa (maxim).Fedde have a better activity to control Dactylogyrus,the N-butanol extracts of Akebia quinata (Thunb.) Dence.and Areca catechu L. have a better activity to control Dactylogyrus.【Conclusion】 The active sites of Datura.metel L.,Macleaya cordata,Cnidium monnieri(L).Cuss.and Ginkgo biloba L.are chloroform extracts.The active sites of Brucea javanica(L.) Merr.and Macleaya microcarpa (maxim).Fedde are petroleum ether extracts.The active sites of Akebia quinata (Thunb.) Dence.and Areca catechu L are N-butanol extracts. |
