Abstract: OBJECTIVE: To assess the antioxidant capacity of aqueous extracts of buds and flowers of Lonicera japonica Thunb.(BLJ and FLJ) using in vitro assays.METHODS: We assessed the in vitro antioxidant activities of aqueous extracts of BLJ and FLJ and compared with that of classical antioxidants vitamin C and butylated hydroxytoluene, using several well-established methods including the 1,1-diphenyl-2-picryl-hydrazyl assay, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) assay, reducing power assay, fluorescence recovery after photobleaching assay, β-carotene bleaching assay, ferric thiocyanate assay, and thiobarbituric acid method.RESULTS: The aqueous extracts of both BLJ and FLJ had similarly potent antioxidant capacity. There were no significance differences between BLJ and FLJ in all the assays.CONCLUSION: The aqueous extracts of both BLJ and FLJ have antioxidant activity with comparable efficacy. These findings suggest that both BLJ and FLJ may have the potential as natural antioxidants.
