摘要: 研究枇杷花系统溶剂提取物抑菌的作用。实验以苯甲酸钠为对照组,分别研究了枇杷花石油醚、氯仿、乙酸乙酯、正丁醇、丙酮、95%乙醇和水的提取物对大肠杆菌、金黄色葡萄球菌、白色念珠菌的抑菌效果,并对不同提取物进行薄层色谱分析。结果表明,枇杷花的提取液对细菌、真菌均有抑制作用,并优于对照组。正丁醇、丙酮提取物对金黄色葡萄球菌抑制能力优于其他溶剂;石油醚提取物对大肠杆菌抑制能力优于其他溶剂;石油醚、乙酸乙酯提取物对白色念珠菌抑制能力优于其他溶剂。

Abstract: The bacteriostasis of systematic solvents extracts from flowers of Eriobotrya japonica (Thunb.) Lindl was studied. Seven systematic solvents extracts were conducted for the inhibitory effects against Escherichia coli, Staphylococcus aureus and Candida albicans, with calcium propionate as control group. The different extracts were tested by thin layer chromatography. The results indicated that the flower of Eriobotrya faponica was well at restraining bacillus and epiphyte. The average inhibitory effects of the flower of Eriobotrya faponica on bacteria and epiphyte were better than control groups. The butanol and acetone extracts had strong effect on Staphylococcus aureus than others. The petroleum ether extract had strong effect on Escherichia coli. The petroleum ether and ethyl acetate extract had strong effect on Candida albicans.
