nutraceutical and cosmeceutical potential of Aloe vera L., human well-being, Polysaccharides are demonstrated as the major component compounds for the bioactivities of Aloe Vera Gel gel, bioactivities, composition, and proportion of gel-components significantly influence the bioactive potential of aloe gel, aloe gel would be of help in optimizing the component of the value chain of aloe processing, bio-active potential to ensure the effective application of Aloe vera gel, biological activity of any substance is mainly implicated by its compositional features, mannose, glucose and galactose monomers which constitute the structural reserve polysaccharide acemannan or ?-(1, 4)-linked acetylated mannose , The structural monsaccharides are present in ?(1,4)- linked mannoses, 1 ?(1,4)-linked glucose, and 1 ?(1-6)-linked galactose form, and some of the mannose monomers are modified by addition of an acetyl group, The molar ratio of sugar and linked acetyl group present in this molecule is 1:3, polysaccharides contain 1?4 glycosidic linkages in between glucose and mannose moiety (glucose: mannose = 1:2.8). Aldopentose, acetylated glucomannan, galactogalacturan, glucogalactomannan, galactoglucoarabinomannan are also the important oligosaccharides or polysaccharides present in Aloe vera, average molecular weight of polysaccharides of the gel was found to be 2 million Da or above and constitutes approximately 0.20% 0.30% of fresh Aloe gel, polysaccharide molecules can hold water molecules in inter-molecular space and attributes the humectant activity to Aloe Vera Gel, immunomodulatory and functional properties to Aloe Vera Gel, act as biological response modifier, Aloe Vera mainly composed of six different types of compounds namely, poly and mono saccharides (mannose, glucose, glucomannan, acemannan etc.), phenolics, vitamins, enzymes, low molecular weight substances and minerals.
