为了优化微波法提取石蒜中石蒜碱的工艺条件,用野生石蒜作原料,以乙醇为提取剂,探索了料液比、微波功率、提取温度、提取时间、提取次数等单因素对微波法提取石蒜碱的影响,用正交试验L9（34）获得了最佳提取工艺条件,并与常规溶剂法进行了比较。结果表明：微波法提取石蒜中石蒜碱的最佳工艺条件为：料液比1：6,微波功率320 W,提取温度60℃,提取时间6 min,提取2次;石蒜碱的提取率为95.5%,产率为0.0391%;提取物中石蒜碱含量为12.35%。与常规溶剂法相比,微波法具备提取时间短、提取率高、提取次数少等优点,总体效果优于常规溶剂法。

To optimize the process conditions of microwave extraction of lycorine from wild Lycoris herb, the single factor experiments of the solid-liquid ratio, microwave watt, extraction temperature, extraction time and extraction times were made by means of using wild Lycoris herb as raw material and ethanol as extractant, and the optimal technics conditions of the extraction were obtained by orthogonal experiment L9（3^4）. Effects of the microwave extraction were compared with those of conventional solvent extraction. Results showed that the optimal...
