摘要 目的通过对黄连提取方法的研究,确定其最佳提取方法的因素及水平。方法比较醇提与水提,选择最佳提取溶剂,以提取次数、提取时间、浸泡时间、溶剂量为考察因素,以浸膏得率和盐酸小檗碱的含量为考察指标,用正交试验法优选黄连提取工艺。结果黄连的最佳提取工艺为分别加12、10、10倍量水,浸泡0.5h,回流提取3次,提取时间分别为1.5、1.5、1.0 h。结论通过对黄连提取工艺的优选,为工业化大生产提供了实验依据。 Objective To ascertain the factors and levels in the best methods by the research of the extract methods of Rhizoma Coptidis. Methods The water was compared with 50% alcohol extraction, and the optimum extraction solvent was chose. The orthogonal design was used to select the optimum extraction process according to the con- tents of inspection, extraction time, immerse time, tile volume of solvent and the number of extraction times. Results The optimum extraction process was as follows: 12, 10, 10 times amount of water was added, and they were refluxed and extracted for 3 times, the extraction time was 1.5, 1.5 and 1 hour. Conclusion It can offer a basis on manufacture in the factory by selection of the optimum extraction process.
