采用牛津杯法测定了荷叶乙醇提取物对大肠埃希氏菌( Escherichia coli)、荧光假单胞菌( Pseudomonas flu-orescens)、铜绿假单胞菌( P.aeruginosa)、蜡叶芽枝霉( Cladosporium herbarum)、酵母菌( Saccharomycete sp.)等肉类致腐菌的抑菌活性.结果表明,荷叶乙醇提取物对大肠埃希氏菌、荧光假单孢菌、铜绿假单孢菌和酵母菌有一定的抑菌作用,且其抑制作用随荷叶提取物中黄酮浓度的增加而增大,但对枝霉无抑菌性.该提取物中黄酮对大肠埃希氏菌、荧光假单孢菌、铜绿假单孢菌、酵母菌的最低抑菌浓度分别为6.250、3.125、1.562和12.500 g/L;最低杀菌浓度分别为12.500、6.250、3.125和25.000 g/L.
採用牛津杯法測定瞭荷葉乙醇提取物對大腸埃希氏菌( Escherichia coli)、熒光假單胞菌( Pseudomonas flu-orescens)、銅綠假單胞菌( P.aeruginosa)、蠟葉芽枝黴( Cladosporium herbarum)、酵母菌( Saccharomycete sp.)等肉類緻腐菌的抑菌活性.結果錶明,荷葉乙醇提取物對大腸埃希氏菌、熒光假單孢菌、銅綠假單孢菌和酵母菌有一定的抑菌作用,且其抑製作用隨荷葉提取物中黃酮濃度的增加而增大,但對枝黴無抑菌性.該提取物中黃酮對大腸埃希氏菌、熒光假單孢菌、銅綠假單孢菌、酵母菌的最低抑菌濃度分彆為6.250、3.125、1.562和12.500 g/L;最低殺菌濃度分彆為12.500、6.250、3.125和25.000 g/L.

Inhibition effects of flavones in ethanol extracts from lotus leaf on meat pathogens , such as Escherichia coli, Pseudomonas fluorescens, P.aeruginosa, Cladosporium herbarum, and Saccharomycete sp., was determinated by oxford-cup method .The results showed that the extract had some antibacterial effects against E.coli, P.fluorescens, P.aeruginosa and Saccharomycete sp., while the inhibition in-creased with the increasing concentration , but no effect on C.herbarum.The extracts minimum inhibitory concentrations to E.coli, P.fluorescens, P.aeruginosa, Saccharomycete were 6.250, 3.125, 1.562 and 12.500 g/L, and the minimum bactericidal concentration were 12.500 , 6.250 , 3.125 and 25.000 g/L, respectively.
