Antioxidant activities on different compatibility proportions of Salvia miltiorrhiza and Pueraria lobata
This study was conducted to investigate the antioxidant effects of different compatibility proportions of Sal-via miltiorrhiza and Pueraria lobata.The active ingredients of different proportions of Salvia miltiorrhiza and Pueraria lobata were extracted using the water extraction methods.Then the ultraviolet spectrophotometry was utilized to deter-mine the scavenging ability of ABTS and DPPH free radical of various extracts of different proportions of S.miltiorrhiza and P.lobata.S.miltiorrhiza exhibited the stronger antioxidant activities than P.lobata;compared with the single herbs,when the proportions of S.miltiorrhiza and P.lobata were 1∶2,3∶1 and 4∶3,these samples possessed the strongest clearance of ABTS and DPPH free radical.S.miltiorrhiza and P.lobata could enhance the antioxidant capacities when decocting together.The study provides a solid scientific basis for the clinical application of S.miltiorrhiza and P.lobata.
