摘　　要：采用生长速率法测定了接骨木叶不同溶剂(石油醚、氯仿、乙酸乙酯、丙酮、乙醇)粗提取物对灰葡萄孢菌菌丝生长的影响.结果表明,接骨木不同溶剂提取物对灰葡萄孢菌的菌丝生长表现出抑制和促进两种作用,其中乙酸乙酯顺序提取物的抑菌效果较好,各浓度都表现出抑制作用;2 000mg/L的乙醇顺序提取物的抑菌效果最好,抑制率为29.922 2%.本试验为开发新型植物源抑菌剂提供了理论依据.The effect of Sambucus williamsii Hance extracts derived from 5 different solvents（petroleum Ether,chloroform,ethyl acetate,acetone and ethanol）on the hyphae growth of Botrytis cinerea Pers.Ex Fr.was studied using the growth rate method.The results showed that the S.williamsii extracts have antibacterial and promoting activity to tested pathogens.Ethyl acetate extract has the better antibacterial effect to tested pathogens,in the gradational extraction method.,and they all showed antibacterial activity;ethanol extract shows the most antibacterial activity,in 2 000 mg/L,inhibition rate reached 29.922 2%.This study can provide the theory basis for exploitation new type botanical antibacterial certain chemicals.
