摘　　要：目的:优选钩藤总生物碱的提取工艺。方法:以钩藤总碱含量和提取液干膏率为综合评价指标,对乙醇用量、浓度、提取时间及次数四因素进行正交考察。结果:钩藤总碱的最佳提取工艺为10倍量75%乙醇提取3次,提取时间2h。结论:提取工艺可稳定可行。Objective ： Investigate the best extract artwork of expressed total alkaloids from Ramulus Uncariae Cum Uncis. Methods：The orthogonal design was adopted with extractive yield and the content of total alkaloids as indices. Four factors were studied in this experiment,including the alcohol consumption, alcohol concentration, time of extraction, and times of extraction. Results ： The best extract process is extract 3 times with 10 times 75% alcohol,each time for 2h. Conclusion：This extract process is stable and feasible.
