采用80%乙醇、水、石油醚3种不同溶剂提取山莓叶中抑菌活性成分,通过抑菌实验结果表明:山莓叶提取物中,其中80%乙醇提取物对大肠杆菌、金黄色葡萄球菌、痢疾志贺氏菌均具有较强的抑制作用,水提取物抑茵作用较弱,石油醚提取物无明显抑茵作用:其中三种提取物对酵母的抑制作用均较弱;80%乙醇提取物对金黄色葡萄球茵、痢疾志贺氏菌、大肠杆菌和酵母的最小抑菌浓度(MIC)为6.25～12.5 mg/mL;80%乙醇提物经30、50、80 ℃的温度各处理2 h,121℃下处理20 min:光照6～18 h,pH5～7仍具有很好的抑菌效果;系统预试实验初步表明:山莓叶乙醇提取物中主要含有多糖及其甙类、鞣质、黄酮类、酚类物、强心甙、有机酸...

Active constituents in Rubus corchorifolius leaves were extracted by three different solvent which were 80% ethanol, water and petrolic ether, and the bacteriostasis was studied. The result showed that： 80% ethanol extraction of Rubus corchorifolius leaves had stronger bacteriostasis on Escherichia coli, Staphylococcus aureus and Shigella dysenteroae, but water extraction had weak bacteriostasis and petro-licether extraction had no bacteriostasis. In addition, extracted antibacterial substance had showed bacteriostasis on Penicilliumsp and Sac...
