Study on Anti-MRS Activity of Nauclea officinalis Leaves

SU Kui et al (Food College of Shihezi University,Shihezi,Xinjiang 832000)  
With methicillin-resistant staphylococcus aureus(MRS),escherichia coli,staphylococcus arureus,proteus vulgaris,bacillus subtilis as the tested strains,the vitro antibacterial activity of extracts from Nauclea officeinalis leaves was determined by filter paper agar diffusion method.The results showed that the extract from N.officeinalis leaves had antibacterial activity on MRS when ethanol which volume fraction was more than 40% was taken as extractant,and the bigger the volume fraction of ethanol was the stronger the antibacterial activity of the extract was.The antibacterial activity of middle and high polar solvent extraction section of ethanol extract from N.officeinalis leaves was the strongest.The decoction of N.officeinalis leaves had antibacterial activity on escherichia coli,while the alcohol extract only had exceedingly weak antibacterial activity on escherichia coli.The alcohol extract and decoction of N.officeinalis leaves only had exceedingly weak antibacterial activities on staphylococcus arureus,proteus vulgaris and bacillus subtilis.
