摘要
Objective:To investigate the antioxidant activity of methanolic extracts of Lantana camara(L.camara)various parts and the determination of their total phenolics content.Methods:The extract was screened for possible antioxidant activities by free radicaI scavenging activity(DPPH),xanthine oxidase inhibition activity and Griess—llosvay method。Results:The results showed that all the plant parts possessed antioxidant properties including radical scavenging,xanthine oxidase ildfibition and nitrites seavenging activities.The antioxidative activities were correlated with the total phenol.The leaves extract of L.camara was more effective than that of other parts.Conclusions:This study suggests that L.camara extracts exhibit great potential for antioxidant activity and may be useful for their nutdtional and medicinal functions.
