摘　　要：采用液-液分配法对圆滑番荔枝叶乙醇提取物进行萃取分离,得到石油醚、三氯甲烷、乙酸乙酯等不同萃取组分。采用生长速率法测定不同萃取组分对胡椒瘟病菌的抑制作用。结果表明:乙酸乙酯萃取组分对胡椒瘟病菌的抑制作用最强,其中20 mg/mL乙酸乙酯萃取组分对胡椒瘟病菌菌丝生长的抑制率达到74.43%,具有较好的抑菌效果。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%.
