摘要
通过建立羟基自由基体系、超氧阴离子自由基体系、DPPH自由基体系、还原力体系、清除双氧水体系,以VC作为参照,研究了樱桃番茄色素在不同体系下的抗氧化活性。结果表明:樱桃番茄色素对羟基自由基、超氧阴离子自由基、DPPH自由基均有较好的清除作用,其清除50%的自由基所对应的样品浓度分别为2.280、16.40、27.54μg/mL,均低于番茄红素纯品,并且其对羟基自由基、超氧阴离子自由基的清除效果明显优于VC。樱桃番茄色素有较强的还原力,其还原力强于VC。此外,樱桃番茄色素能够清除双氧水,但其清除作用低于VC。综上所述,樱桃番茄色素具有良好的抗氧化活性,可以用于清除自由基产品的开发。
In order to evaluate the antioxidant activities of pigment in cherry tomato, reaction systems of hydroxyl free radicals,super oxide anion free radicals, DPPH free radicals and reducing force as well as removing hydrogen peroxide were established.Then the antioxidant activities of pigment in cherry tomato and Vc were measured and compared in different reaction systems. The results indicated that pigment in cherry tomato could effectively scavenge hydroxyl free radicals, super oxide anion free radicals, and DPPH free radicals. The sample concentrations scavenging 50% of free radicals respectively were 2.280,16.40,27.54μg/mL,which were lower than pure lycopene.Compared with Vc,it had a better effect on the elimination of these free radicals.Pigment in cherry tomato had stronger reducing force than Vc.ln addition, pigment in cherry tomato was capable to remove hydrogen peroxide,but its scavenging effect was lower than Vc.To sum up, pigment in cherry tomato had good antioxidant activities,which could be used to develop products scavenging free radicals.
