摘　　要：目的:研究地骨皮有效部位的提取工艺。方法:采用正交设计法,选取浸膏得率和香草酸的得率作为评价指标。对溶剂用量、提取时间和提取次数三个因素选用L9(34)正交表进行考察。结果:确定最佳工艺为10倍量溶剂,每次1h,提取3次。结论:为地骨皮生产提供了实验基础。Objective ：To study on the optimal extraction process of the effective compositions of Cortex Lycii Radicis. Methods ： The orthognnal design was adopted with extractive yield and the content of cinnamic acid and vanillic acid as indices Three factors were studied in this experiment, including the solvent consumption, time of extraction and times of extraction. Results ： It was concluded that the optimal extracting condition was 1% aqueous sodium bicarbonate consummated ten times the amount of material, being extracted three times, with each time lasting for 60 minutes. Conclusion ： This paper provided a basis for the production of Cortex Lycii Radicis.
