摘　　要：目的:研究葛根的最佳提取工艺。方法:对葛根饮片提取方法进行单因素考察,以干浸膏得率、黄酮总得率、葛根素含量作为考察指标优选提取方法;再运用L16(45)正交设计表优化葛根提取工艺。结果:以水提连续回流效果最佳,葛根提取最佳工艺为:8倍量水,提取2次,每次1.5h。结论:结合实际生产,采用本法可降低成本、提高葛根得率。Objective： To study the optimum extraction technology of Pueraria. Methods： Taking the single factor extraction method, choosing dry extraction rate, total yield of flavonoids, content of puerarin extraction as the indexes to optimize extraction method; Ac- cording to the results, using E16 （4^5） orthogonal design table to optimize extracting process. Results： The water extraction and continu- ous reflux was the best, Pueraria extracting optimum process as follows： 8 times the amount of water, extracted two times, each for 1.5 hours. Conclusion ： combined with the actual production, the use of this law could reduce costs and improve the yield of Pueraria.
