摘要: 为优化玛卡(Lepidium meyenii Walp.)多糖的提取工艺,提高多糖的产率,采用响应面法考察超声温度(A)、提取时间(B)和料液比(C)3个因素对玛卡多糖提取率的影响,同时考察其中存在的交互作用(A×BA×CB×C)。结果表明,最佳工艺条件为超声温度60 ℃、提取时间40 min、液料比40∶1,在最佳工艺条件组合下,测得玛卡多糖提取率为51.21%。

Abstract: To optimize the extraction process of Maca polysaccharide and improve the yield of maca polysaccharide. The response surface methodology was used to investigate the effects of ultrasonic temperature (A), extraction time (B) and solid-liquid ratio (C) on the extraction rate of maca polysaccharide, and the interaction among them (A×B, A×C, and B×C) was investigated, and the optimal extraction conditions were obtained. Results showed that the optimum conditions were as follows: Ultrasonic temperature 60 ℃, extraction time 40 min, liquid-solid ratio 40∶1. Under the optimum conditions, the extraction rate was 51.21%.

Key words: Maca, ultrasound extraction, polysaccharide, response surface
