目的:以小檗碱为定量指标,研究“前愈”无糖颗粒的黄柏提取工艺。方法:采用正交试验法进行优选,高效液相色谱法测定小檗碱含量。结果:乙醇浓度对提取有显著性影响,其它对小檗碱的提取也有影响,优选出最佳提取工艺为A3B3C2。结论:药材1O倍量85％乙醇回流提取,两次提取300min为最佳工艺。
OBJECTIVE: To study the extraction process of “Cured Precipitated” sugar-free granules by using berberine as a quantitative index. Methods: The orthogonal test was used to determine the content of berberine by HPLC. Results: Ethanol concentration had a significant effect on the extraction, and other extraction of berberine also had an effect. The best extraction process was A3B3C2. Conclusion: 1O times the amount of medicinal herbs 85% ethanol reflux extraction, extracted twice 300min for the best process.
