摘要:

采用还原能力测定、清除羟自由基(·OH)能力、清除超氧阴离子自由基(O2·)能力和对DPPH 自由基的抑制作用对高丛越橘蓝丰、半高丛越橘北春、矮丛越橘美登及野生品种越橘果实花色苷进行体外抗氧化活性研究,并测定其中花色苷含量。结果表明:花色苷粗品中蓝丰、北春、美登和野生越橘的花色苷含量依次为19.77、12.67、24.73、32.44mg/g;4 种果实花色苷皆有良好的抗氧化活性,在溶液质量浓度相同的情况下,4 种越橘果实花色苷溶液的抗氧化活性与花色苷含量呈一定的量效关系,野生越橘的还原能力、清除·OH 能力、清除O2·能力和清除DPPH 自由基能力均最高,矮丛越橘美登次之;而在花色苷含量相同的情况下,高丛越橘蓝丰、半高丛越橘北春、矮丛越橘美登及野生品种越橘果实的花色苷抗氧化活性不同,推测是由于其花色苷组分及其含量不同所致。

Abstract:

To take full advantage of the bilberry resources, DPPH, hydroxyl and superoxide anion free radical scavenging and reducing power assays were used to study the in vitro antioxidant activity of the fruits of cultivated bilberry varieties, including Lanfeng, Beichun, Meideng, and wild bilberry fruits. The contents of polyphenol and anthocyanins were also determined. The results showed that, the anthocyanin content of Lanfeng, Beichun, Meideng and wild bilberry were 19.77, 12.67, 24.73 mg/g and 32.44 mg/g frozen fruit, respectively, and anthocyanin had noticeable antioxidant activities. Among the four varieties of bilberry, the antioxidant activity of wild bilberry was the highest, followed by Meideng. The anthocyanins from the four varieties of bilberry had different antioxidant effects at the same concentrations. It is deduced that this is ascribed to the differences in anthocyanin composition and content.

Key words: bilberry, anthocyanins, antioxidant activities
