Abstract:
Taking 8 species of Rubus spp. as materials,disk diffusion method and tube doubling dilution method were applied to test the antimicrobial activity against Staphylococcus aureus 91053,Salmonella pullorum,Enterococcus faecalis,Escherichia coli O1 and Pseudomonas aeruginosa.The antioxidant activity was investigated by measuring the scavenging activity of hydroxyl radicals (?OH) produced by Fenton reaction and superoxide radicals (O?[TX-*4]2) generated from the autoxidation of pyrogallol determined by colorimetry,to evaluat antimicrobial,antioxidant activities of Rubus spp..The results showed that the water extracts of Rubus spp.showed the highest antimicrobial activity against Staphylococcus aureus 91053 and Escherichia coli O1,among which R.corchorifolius,R.coreanus and R.parvifolius presented the lowest MBC(37.5 mg/mL); R. spp.in the test showed certain scavenging effect on hydroxyl radicals (?OH) and superoxide radicals (O?[TX-*4]2),and the ability of R.alceaefolius,R.parvifolius and R.corchorifolius?was highest.The results showed that R.corchorifolius,R.parvifolius,andR.coreanus could be studied as new antimicrobial drugs,and R.alceaefolius,R.parvifolius and R.corchorifolius could be used as new antioxidant drugs.
