摘要
以云南栽培玛咖干粉为原料,对其中总生物碱的提取工艺进行优化。采用热水为提取溶剂,以提取温度、提取时间和料液比为考察对象,在单因素优化的基础上设计3因素3水平正交实验,研究玛咖总生物碱的最优提取条件。结果表明,各因素对玛咖总生物碱提取得率的影响顺序依次为:提取时间>料液比>提取温度。最优提取工艺为:料液比1:20(g:mL),温度70℃,时间100min,在此条件下,玛咖总生物碱提取得率为1.58%。
Extraction process of total alkaloids from maca （Lepidium meyenii walp.）cultivated in Yunnan was investigated.With hot water as extraction solvent, the effect of extraction temperature, extraction time and solid- liquid ratio on the yield of total alkaloids were optimized and the best extraction conditions were determined with single factor test followed by three factor-three level orthogonal experiment.The results showed that the effect of the investigated factors on the total alkaloids extraction yield was in the order as=extraction time 〉 solid-liquid ratio 〉 extraction temperature.The optimal extraction conditions were that solid- liquid ratio of 1 ：20 （ g： mL）, extraction temperature of 70℃ and extraction time of 100min. Under these conditions the total alkaloids extraction yield was 1.58%.
