摘要
采用热水浸提法提取库拉索芦荟花多糖,对温度、时间、加水量、芦荟花粒度4个工艺条件进行了研究.本实验条件下,芦荟花多糖提取的最佳条件为:温度:100℃;粒度:40-60目;时间:4 h;加水量:100 mL.分两次提取比单次提取多糖收率可提高10%.
Hot water is used for polysaccharide extraction of Aloe barbadensis Miller flower.Four factors such as temperature,time,water adding volume,and granular size of aloe flower are investigated on the extraction yield.The results show that the optimum extraction conditions of aloe flower polysaccharide are temperature 100 ℃,extracting time 4 h,water adding volume 100 mL,granular size 40-60 mesh.Two batches of extraction can yield 58.41 mg/g polysaccharide,about 10% higher than once batch method under the same c...
