- 摘要:
- 以山楂叶为试材,以液料比、pH值、提取温度、提取时间为考察指标,进行单因素试验和正交实验,研究了碱性条件下山楂叶中总黄酮的最佳提取工艺。结果表明:最佳提取工艺条件为液料比25∶1 mL/g、pH 8.5、提取温度为90℃,用60%的乙醇提取3 h,此条件下得到的总黄酮提取率为7.97 mg/g。
- Abstract:
- Taking hawthorn leaf as material,based on the different ratio of liquid to solid、pH、extraction temperature、extraction time,the single factor and orthogonal design experiments were conducted,and the optimal extraction process of total flavonoids from hawthorn leaves was obtained.The results showed that ratio of liqutid to material was 25∶1 mL/g,pH was 8.5,extraction temperature was 90℃ extracting with 60% ethanol in 3 h.Verifing in these conditions,flavonoids extracting reached 7.97 mg/g.
