Structure of Neutral Polysaccharides from Skin of Aloe vera Irrigated with Seawater

Changhong Wang

Abstract

After being extracted with hot water and precipitated with alcohol, crude polysaccharide is obtained from skin of Aloe vera. 4 Fractions are prepared by further purification with cellulose DEAE-52. SAPS-A is a most fraction which is made of neutral monosaccharides. From fraction SAPS-A, a purer fraction SAPS-1 is separated by sephadex G-100. The analysis of sepharose 4B, UV, IR and NMR show SAPS-1 is a 6-acetylated partially β-(1-4)-D-Mannan, whose weight is 40±2 kDa.
