【摘要】 目的:为确定白首乌中可溶性多糖的提取工艺。方法:对料液比、温度、时间等分别进行了单因素试验和L9(33)正交实验,并通过极差、方差分析对提取过程中显著影响提取率的因素进行了统计分析。结果:结果表明温度和料液比显著影响可溶性多糖的提取率。结论 最佳工艺为料液比1:20、温度100℃、时间2h,提取次数为1次。更多还原

【Abstract】 Object: In order to know the extraction technology of soluble polysaccharides from radix Cynanchum bungei. Methods:single factor test and orthogonal experiment design methods L9(33) were applied to analyze the influence of each factor in solid-liquidratio, temperature and time on the extraction percent of the polysaccharides. Results: Experimental results indicated that tempera-ture and solid-liquid ratio significantly affect the extraction percent of the soluble polysaccharides. Conclusion The optimum solid-liquid ratio is 1:20,temperature is 100℃ and the extraction time is 2h, the extraction degree is 1 time.更多还原
