摘　　要：以甜叶菊糖苷的水提浸出率为参考指标,通过单因素和正交设计优化甜叶菊糖苷的水提工艺,得到最优的水提条件为:提取温度70℃、提取时间3h、料液比1:15,在此条件下甜叶菊糖苷的水提浸出率可达到97%。The present study aimed at developing an optimal procedure for the water extraction of stevia glycoside from the leaves of the stevia plant. The optimal values for improved stevia glycoside yield were determined by one-factor and orthogonal experiment design methods as follows： extraction temperature 70 ℃, extraction time 3 hours, solid-to-liquid ratio 1：15（g/mL）. Under such conditions, a maximum stevia golycoside yield of up to 97% was obtained.
