【摘要】 为了探究白头翁水溶性多糖的提取工艺,本研究采用单因素试验和L9(34)正交试验,考察料液比、提取时间、提取次数和提取温度对水溶性多糖提取率的影响,优选白头翁水溶性多糖的最佳提取工艺条件。结果表明,白头翁水溶性多糖最佳提取工艺条件为:料液比为1:17,100℃提取6 h,提取6次,白头翁水溶性多糖含量为5.07%。为白头翁水溶性多糖的进一步研究奠定了基础。更多还原

【Abstract】 To optimize the extraction procedure of water-soluble polysaccharides from Radix Pulsatilla, single factor test and orthogonal test were designed to investigate the effects of solidliquid ratio, extraction time and number of extraction. The results showed that the optimal extracting conditions were the solid-liquid ratio of 1:17, extraction time of 6 hrs and extracting 6 times at 100 ℃ in water. Under these conditions, the extraction percentage was up to 5.07%. This study provided the basis for further research of water-soluble polysaccharides in Radix Pulsatilla.更多还原
