通过对地不容总生物碱的不同提取方法进行比较,从而确定最佳提取工艺.进一步采用正交设计法,以总生物碱提取率为考察指标,通过对乙醇浓度、溶媒比、超声波提取时间、回流时间4个因素进行考察,确定最佳提取工艺为:75%乙醇为提取溶剂,乙醇与地不容的溶媒比为12,先超声提取60min,再回流提取1h,共回流提取2次为地不容总生物碱提取的最佳条件.本工艺简单合理,提取率高,具有良好的可行性.
Through the comparison of different extraction methods of total alkaloids, the optimal extraction process was determined.Using the orthogonal design method, the extraction rate of total alkaloids was taken as the index of investigation, and the ethanol concentration, solvent ratio, ultrasonic extraction time, Reflux time of four factors were investigated to determine the best extraction process: 75% ethanol as the extraction solvent, ethanol and the ground can not tolerate the solvent ratio of 12, first ultrasonic extraction 60min, and then reflux extraction 1h, total reflux was extracted twice Total alkaloid extraction of the best conditions. The process is simple and reasonable, high extraction rate, with good feasibility.
