Test and Extraction to the Aloe Polysaccharide in Aloe Beverage

Tang Wen

Abstract

The author provides the main conditions with which the aloe polysaccharide is extracted from aloe beverage by an orthogonal test and testing analysis.The results show that the optimum conditions for extracting the aloe polysaccharide in aloe beverage are that:temperature 60 ℃;ethanol volume fraction 95%;extracting time 1 h;ethanol expenditure 9 times of the sample.Meantime,the author tests the content of aloe polysaccharide by using the colorimetric method of phenol sulfuric acid.
