摘要
研究了醇提-酯萃法提取竹叶中总黄酮的各种影响因素,采用正交试验寻找最佳提取条件,实验结果表明:15倍原料重的75%乙醇在70℃温度下提取5h为最佳.
Different factors determining the content of the total flavonids in alcohol and ester extracts has been studied in this paper.The optimum conditions was obtained by using orthogonal design.The results showed that the optimal conditions for the extraction was 70 ℃,15∶1 of 75% ethyl alcohol solution to bamboo leaves weight ratio,and extraction for 5 hours.
