摘　　要：[目的]探讨山楂叶中总黄酮的最佳提取工艺。[方法]采用单因素和响应面分析法,研究预浸泡时间、料液比、提取时间和提取次数等因素对山楂叶中总黄酮提取率的影响。[结果]山楂叶中总黄酮的最佳提取工艺为预浸泡时间2 h,料液比1∶26 g/ml,浸提时间120 min,浸提次数2次。[结论]该提取工艺能显著提高山楂叶中总黄酮的提取率。[ Objective] To study the optimal extraction process of total flavonoids from hawthorn leaves. [ Method] The factors that affect the extraction rate of total flavonoids were investigated by single-factor experiment and response surface methodology,including pre-soaking time,solidliquid ratio, extraction time and extraction times. [ Result ] The optima] extraction process was as follows：pre-soaking time was 2 h, solid-liquid ratio was 1：26 （g/ml） ,extracting time was 120 min, and extracting times was 2. [ Conclusion ] The extraction rate of total flavonoids was improved largely through the extraction process.
