响应面法优化云南野生玛卡多糖的提取工艺

Optimization of Extraction Processes for Yunnan Wild Maca Polysaccharides by Response Surface Analysis

以多糖提取率为考察指标,用水提醇沉法,在单因素试验基础上,响应面优化玛卡多糖的最佳提取工艺。确定玛卡多糖的最佳提取工艺为:料液比1:60 g/mL,提取温度90℃,提取时间9.5 h,提取次数5次,多糖提取率为39.78%±0.89%。

Taking the yield of polysaccharide as indicator, using single factor test, response surface methodology（RSM） was employed to optimize the maca polysaccharides of water extracting-alcohol precipitating method. The best extraction process of the maca polysaccharides was 1：60 g/mL for the ratio of material to liquid, 90℃ for extracting temperature, 9.5 h for time and 5 times for extraction. The yield of polysaccharide was 39.78%±0.89%.
