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 photo-bleaching 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.
