不同工艺对黄柏中黄连素提取量的影响

Effect of different extraction processes on extraction volume of Berberine in Cortex Phellodendri

目的 探讨从黄柏中提取黄连素的最佳工艺，方法 分别采用酸醇法（酸醇原法，酸醇改进Ⅰ法和酸醇改进Ⅱ法），碱提取法，醇提取法等提取黄柏中黄连素。结果 酸醇原法，酸醇改进Ⅰ法，酸醇改进Ⅱ法，碱提取法，醇提取法的提取率分别为0.91%,0.94%1.02%,0.86%,0.89%。结论 在黄柏中提取黄连素，应用酸醇改进Ⅰ法与酸醇改进Ⅱ法的提取率均高于酸醇原法，碱提取法和醇提取法。
