摘　　要：为优化银杏叶聚戊烯醇乙酸酯的水解工艺,在单因素实验的基础上,运用Box-Behnken中心组合实验和响应面法考察了水解时间、碱浓度和水解温度3个因素对水解率的影响。结果表明,最佳的水解工艺为:水解时间3h,碱浓度6%,水解温度50℃,银杏叶聚戊烯醇乙酸酯水解率为96.52%。The optimization process parameters of hydrolyzation of polyprenyl acetates from Ginkgo biloba leaves were studied. Based on the single factor test analysis, the effects of three variables （ hydrolyzation time, alkali concentration and hydrolyzation temperature）on the hydrolysis rate were evaluated by Box-Behnken central composite experimental design and response surface methodology analysis.The results indicated that hydrolyzation time of 3h, alkali concentration of 6% and hydrolyzation temperature of 50℃ were the optimum conditions.Under these optimized conditions ,the hydrolysis rate was 96.52%.
