摘要:

为了分析花青素提取液的体外抗氧化活性。以‘隆子黑青稞’为原料,采用超声波辅助酸水法提取‘隆子黑青稞’花青素,并采用正交实验优化了工艺条件。结果表明,‘隆子黑青稞’花青素的提取得率受料液比的影响最大,其次是水浴提取温度和超声温度,在液料比20 mL:1 g,超声温度40℃,超声时间40 min,水浴提取温度60℃,水浴提取时间为3 h的提取条件下,得率最高。同一样品对不同自由基的清除能力不同,整体来说,对超氧阴离子自由基的清除能力最强,‘隆子黑青稞’花青素粗提液对自由基有一定的清除能力。

Abstract:

In order to analyze the antioxidant activity of anthocyanin extracts in vitro, the anthocyanins were extracted from ‘Longzi black barley’ by ultrasonic assisted acid water method, and the processing conditions were optimized by orthogonal experiment. The results showed that the ratio of material to liquid had the greatest effect on the extraction rate of anthocyanins, followed by water bath extraction temperature and ultrasonic temperature. The optimal extraction conditions were liquid to material ratio of 20 mL:1 g, ultrasonic temperature of 40℃, ultrasonic time of 40min, water bath extraction temperature of 60℃, and water bath extraction time of 3 h. The same sample had different scavenging ability for different free radicals. On the whole, the scavenging ability for superoxide anion free radicals is the strongest, and the anthocyanin crude extract of ‘Longzi black barley’ had certain scavenging ability for free radicals.
