| Abstract: | Annona glabra leaf ethanol extracts were extracted by liquid -liquid partition method. Getting different petroleum ether, trichloromethane, ethyl acetate extract components. Testing the different components antifungal activity against Phytophthora capsici with growth rate method. The results showed that the ethyl acetate extract components had high inhibition rate against Phytophthora capsici mycelium growth. When the concentration was 20 mg/mL, the inhibition rate reached to 74.43%. |
