| 摘 要： | 用正交试验比较固液比、浸提时间、浸提温度、超声时间对甜菜碱提取率的影响,选取的因素中,对柴达木枸杞叶甜菜碱提取率影响程度依次为：超声时间〉固液比〉浸提时间〉浸提温度。最佳提取工艺是固液比（g/mL）为1∶60,60℃,浸提4h,超声10m in。

| Abstract: | The effects of ratio of solid and liquid,extraction time,extraction temperature,ultrasonic time on extraction rate of betaine in leaf of Qaidam Lycium barbarum were studied by orthogonal design.The order of factors affecting extraction rate of betaine was ultrasonic time ratio of solid and liquidextraction timeextraction temperature.The optimum extractions were as follows：solid-liquid ratio of 1∶60,extraction temperature of 60℃,extraction time of 4h,ultrasonic time of 10min. |
