Study on Antioxidant and Antibacterial Activity in vitro of Echinops latifolius Tausch Polysaccharides
摘要
Abstract
In this study antioxidant activity and antibacterial activity of Echinops latifolius Tausch polysaccha-rides was researched.The result showed that when the initial concentrations were same,ETCP has a highest effect of total reducing capacity,clearance of DPPH free radical in vitro,higher than ETPA,significantly higher than ETPB and ETPC.When the added concentrations were 0.1 -0.3 mg /mL,ETCP has a little higher scavenging effects on free radicals than that of ETPA,but no obvious difference;when the added concentrations were 0.4 mg /mL,ETCP has a little higher scavenging effects on free radicals than that of ETPA,ETPA has a little higher scavenging effects than that of ETPB,and difference were not significant,they were significantly higher than that ETPC,when the add-ed concentrations were 0.5 mg /mL,ETCP has a higher scavenging effects on free radicals than that of ETPA,ET-PB,significantly higher than ETPC.Experimental condition,ETCP and ETPA were less sensitive to E.coli,the mini-mal inhibitory concentration(MIC)were 0.62 mg /mL,ETPB and ETPC were insensitive the MIC were 1.25 mg /mL;ETCP,ETPA,ETPB and ETPC were insensitive to Staphylococcus aureus,the MIC were 1.25,2.50,2.50,2.50 mg /mL respectively;ETCP,ETPB and ETPC were insensitive to Pseudomonas aeruginosa,the MIC were 5.00 mg /mL,ETPA had no inhibition to Pseudomonas aeruginosa;ETCP,ETPA,ETPB and ETPC were insensitive to Salmonella,the MIC were 2.50,2.50,1 .25,5.00 mg /mL respectively.It means ETCP has the strongest antioxidant effect and sec-ondly for ETPA,ETPB and ETPC were weak.ETCP and ETPA has a certain resistance to activity of E.coli,and ET-PA,ETPB and ETPC has no antibacterial action to Staphylococcus aureus,Pseudomonas aeruginosa and Salmonella.关键词
