摘要
研究沙棘中总黄酮的提取条件及含量测定。通过实验得出最佳条件是:乙醇的浓度为80%。pH为9,时间为6h,样品前处理是用石油醚除去油脂、色素等杂质。这种方法简单易行,用芦丁制出标准曲线,推出计算公式,计算沙棘叶中总黄酮的含量(以芦丁计)。
The extracting condition and content of total flavone in the hippopae(TFH)were studied in this article.The results showed the optimum condition of the abstraction:the concentration of ethanol was 80% and the value of pH was 9,along with the abstracting time of 6 h.The sample was pretreated with petroleum ether to get rid of inclusion such as smear and pigment,and this method was realizable.The standard curve was done with rutin to give standard curve for calculating the content of TFH in the leaves(calculate with rutin).
