| 摘 要： | 根据黄连须中主要有效成分小檗碱易溶于乙醇的性质 ,采用正交设计筛选醇提工艺的最佳条件 ,用紫外分光光度法 ,以提取物中盐酸小檗碱的含量为指标优选提取工艺。结果表明 :黄连须粗粉中加入 5 %的中药提取因子 ,37℃恒温浸泡 6h,乙醇连续回流 3次 ,每次 1h ,总加醇量为2 2倍 ,所得盐酸小檗碱的总量最高 ,提取的盐酸小檗碱总量可达 3.81% ,该工艺为黄连须的更好利用提供了实验依据

| Abstract: | The ethanol extraction procedure, used in extracting berberine-hydrochloric(BBH) from fibrous radix of coptis is described. Optimum conditions were determined as extracted with 5 percent herbal extracting factor, 22 times amounts of ethanol, soaked 6 hours, circumfluence 3 times for 1 hour for every decoction by orthogonal analysis. The results proved that, the extraction procedure were able to obtain 3.81 percent berberine from fibrous radix of coptis. |
