| 摘 要： | 为了简化刺梨多糖的提取工艺,达到节能、省时、方便的目的,用水提法提取刺梨多糖,探讨乙醇质量分数、提取温度、加热时间和料液比对多糖提取率的影响.采用正交实验优化工艺,以多糖提取率为评价指标,用蒽酮硫酸法测定多糖含量.水提法的最佳工艺条件为温度75℃,时间1h,料液比1∶40,乙醇质量分数0%.在此条件下刺梨多糖的得率为4.7%.

| Abstract: | To simplify the extraction process of cili polysaccharide so that energy and time can be saved to achieve convenience,water extraction of polysaccharides from roxburgh rose is studied in this paper.Effects of extraction temperature,time,solid-liquid ratio and ethanol concentration are also investigated.Orthogonal test optimization of process and anthrone sulfurie acid method was used for the determination of polysaccharide content.The results indicated that the best technological conditions for extraction is 75 ℃,1 hours,1∶40 solid-liquid ratio,and 0% ethanol concentration.Under these conditions,the yield of polysaccharide from Roxburgh Rose was 4.7%. |
