摘要: 比较研究高良姜和大高良姜总黄酮的体外抗氧化活性。采用2,2-二苯基-1-苦味酰基(DPPH)自由基体系、超氧阴离子自由基体系、羟自由基体系对高良姜和大高良姜总黄酮的抗氧化活性进行比较研究,并同VC和BHT的抗氧化活性进行比较。在质量浓度 (0.05~0.5mg/mL)范围内,高良姜和大高良姜总黄酮对DPPH自由基、·OH、O2·的清除率分别为94.0%和94.4%、82.1%和80.7%、16.6%和16.7%,其抗氧化活性微弱于VC和BHT。结果表明,大高良姜中总黄酮的抗氧化活性大于高良姜。

Abstract: The main purpose of this study was to comparatively investigate the antioxidant activity of total flavonoids from Alpinia officinarum Hance and Alpinia galangal Willd in vitro. The antioxidant evaluation was achieved by using DPPH, superoxide anion and hydroxyl free radical systems and comparing with the reference materials VC and BHT. In a certain concentration range (0.05-0.5 mg/mL), the scavenging rates of total flavonoids from Alpinia officinarum Hance and Alpinia galangal Willd against DPPH, superoxide anion and hydroxyl free radical were found to be 94.0% and 94.4%, 82.1% and 80.7%, and 16.6% and 16.7%, respectively, slightly inferior to those of VC and BHT. In general, total flavonoids from Alpinia galangal Willd are better antioxidants than those from Alpinia officinarum Hance.

Key words: Alpinia officinarum Hance, Alpinia galangal Willd, total flavonoids, antioxidant activity
