研究番石榴叶提取物-槲皮素对大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌、沙门氏菌、志贺氏菌的抑制作用.采用滤纸圆片法,进行抑菌药效试验.结果表明:番石榴叶提取物对大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌、沙门氏菌、志贺氏菌的抑制作用很明显.其中对大肠杆菌、沙门氏菌抑制能力最强,MIC=1.25%,抑菌圈直径为13.5 mm、18.7 mm,对金黄色葡萄球菌的抑制作用较弱,MIC=5%,抑菌圈直径为10.5 mm.
研究番石榴葉提取物-槲皮素對大腸桿菌、枯草芽孢桿菌、金黃色葡萄毬菌、沙門氏菌、誌賀氏菌的抑製作用.採用濾紙圓片法,進行抑菌藥效試驗.結果錶明:番石榴葉提取物對大腸桿菌、枯草芽孢桿菌、金黃色葡萄毬菌、沙門氏菌、誌賀氏菌的抑製作用很明顯.其中對大腸桿菌、沙門氏菌抑製能力最彊,MIC=1.25%,抑菌圈直徑為13.5 mm、18.7 mm,對金黃色葡萄毬菌的抑製作用較弱,MIC=5%,抑菌圈直徑為10.5 mm.

@@@@The guava leaves extract-quercetin had inhibition on Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Salmonella, Shigella in vitro. It used filter paper discs for antibacterial efficacy trials. The results showed that the guava leaves extract's inhibition in E. coli, Bacillus subtilis, Staphylococcus aureus, Salmonella, Shigella was obvious. Its inhibition for E. coli, Salmonella was strongest, MIC=1.25%, diameter of inhibition zone was 13.5 mm, 18.7 mm. Its inhibition for for Staphylococcus aureus was weak, MIC=5%, diameter of inhibition zone was 10.5 mm.
