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.

与维生素C和丁基羟基甲苯比较，金银花花蕾水提物的抗氧化能力。

目的评价金银花花蕾水提物的抗氧化能力。(BLJ和FLJ)。方法采用1,1-二苯基-2-苦味酰肼法、2,2′-氮基-双(3-乙基苯并噻唑-6-磺酸)法、还原力法、光漂白后荧光恢复法、β-胡萝卜素漂白法、硫氰酸铁法、硫代巴比托酸法等方法，对BLJ和FLJ水提物的体外抗氧化活性进行评价，并与经典抗氧化剂维生素C和丁基羟基甲苯的体外抗氧化活性进行比较。结果牛膝姜和牛膝姜的水提物均具有较强的抗氧化能力。BLJ和FLJ在所有试验中均无显著性差异。结论枸杞多糖和茯苓多糖水提物均具有抗氧化活性，且具有相当的抗氧化效果。这些发现表明，BLJ和FLJ可能都有作为天然抗氧化剂的潜力。
