摘　　要：研究了溶剂回流法提取石蒜中的石蒜碱、力可他敏和加兰他敏等生物碱。探讨了回流时间、溶剂量和溶液pH值等因素对生物碱提取率的影响,并且同其他提取法如微波辅助提取法等进行比较。实验结果表明,在pH=5、回流温度95℃、回流时间为1 h时,生物碱的提取效果最好。实验表明在所用的材料中活性碳吸附效果最好。In this manuscript, solvent circumfluence was adopt to abstract lycorine, homolycorine and galanthamine from Lycoris. And the effect of circumfluence time, solvent quantity and pH value on the alkaliodal extration＇s rate was checked. And compared with other extration methord. The result shows that the effect of abstraction effectiveness was the best choice when the circumfluence temperature is 95 ℃ ,circumfluence time is 1 hour and pH value is 5. It shows that the activated carbon adsorbent is cuso the best one.
