Determination of Poly-saccharides in Aloe and Aloe Dry Powder by Gas Chromatography

The poly-saccharides of aloe and aloe dry powder samples were analyzed by gas chromatography, which using alcohol deposition saccharides of aloe and aloe dry powder, after hydrolyzing and derivativing saccharides. Under optimum conditions, a mixed column of OV 225 and OS 138 was utilized. It attained a better quantitative determinations by the condition of xylitol was internal standard. Experimental results indicated that there was a little glucose in the aloe which had not been degraded; Mannose and glucose were major saccharides in the aloe which had been degraded. The similar result was obtained from carbohydrates which had reacted with alcohol deposition. These analytic results indicated that the saccharides of aloe and aloe dry powder samples were manna polysaccharide and manna glucpolysaccharide.
