提取溶剂对青稞提取物总酚、黄酮含量及其抗氧化活性的影响
Effect of different solvents on total phenol ic content,total flavonoid content and antioxidant activity of highland barley
摘要
Abstract
The objectives of this study were to evaluate total phenolic,to-tal flavonoid content and antioxidant activities of different extraction from three kinds of highland barley.The results showed that 95% ethanol and 60% acetone were better to extract phenolic compounds than other solvents.Total phenolic and total flavonoid contents,antioxidant activities of Zangqing 2000 using different solvents were higher than that of Xunhua and Shangri-la highland barley.Meanwhile,the highest total phenolic content of Zangqing 2000 was 211.92 mg GAE/100 g DW in 60%acetone, the highest total flavonoid content of Zangqing 2000 was 60.11 mg RT/100 g DW in 60% ethanol, the highest ABTS scavenging ability and total antioxidant activity of Zangqing 2000 were 1 .85 and 9.28 mmol TEAC/100 g DW,respectively.Further-more,there was a significant correlation between total phenolic con-tent and antioxidant methods.FRAP method was significantly corre-lated to DPPH and ABTS methods.These results suggested that highland barley was rich in phenolic content and considered as a good natural antioxidant resource.关键词
