摘　　要：利用Box-Behnken Design(BBD)分析提取时间、超声时间、料液比和乙醇浓度对樟树叶中木脂素及多酚得率的影响。结果表明:最优的提取条件为提取时间78min,超声时间3 min,料液比(m(樟树叶)∶V(乙醇))1∶22(g/mL),乙醇体积分数80%。此条件下樟树叶木脂素和多酚得率分别为44.89,48.17mg/g。Response surface methodology(RSM)based on Box Behnken Design(BBD)was employed to optimize the extraction conditions including the liquid-to-solid ratio,ultrasonic time,ethanol concentration and extraction time.The optimized conditions were as follows:liquid-to-solid ratio 1∶22(g/mL),ultrasonic time 3 min,ethanol concentration 80%and extraction time 78 min.Under these conditions,the experimental yield of lignans and polyphenol were 44.89 mg/g,48.17 mg/g,respectively.
