Acemannan Production on Aloe Species under Stresses of Ph and Desiccation and Its Therapeutic Significance in Dermal Malaise of Uv Irradiated Mice

Abstract

The studied concluded that Aloe plants showed better vegetative growth and yield at higher soil pH 7.5 and moderate moisture condition at crop coefficient kc 0.3 and 0.4. newlineLow soil pH and higher moisture supplementation were not suitable for expression improved phonological and physiological attributes rather it directed the characteristics to be suppressed. A. vera plants rapidly exhibited more tolerance to lower soil pH as compared to A. ferox plants. Similar pattern of results were recorded under the study of soil moisture or desiccation. However, effect of change of soil pH played a dominant role. newlineQualitative chemical compositions of Aloe gels measured as parameters viz., quality guideline parameters (pH, EC, organic acids viz., malic, lactic, oxalic, salicylic), mineral compositions (N, P, K, Na, Ca, Mg, Fe, Zn, Cu), nutritive contents (sugar, protein, vitamin, phenols, fibre, ash), physico-chmeical properties of acemannan (density, viscosity, thermal stability, solubility), hydrolytes composition of acemannan (mannos, glucose, galactose, xylose) were found significantly variable under influence of different treatments of soil pH and moisture supplements during cultivation practices of Aloe plants, but the affects were recorded relatively less variable between the plant species. The International Aloe Science Council (IASC, 2004) presented the guideline for level of these parameters almost analogous for gels of both the plant species (A. vera and A. ferox). However, all the attributes were observed with more magnitude in case of Aloe ferox as compared to Aloe vera. The variability in the results might be concluded with the content of mannosyl residues as a reserve polysaccharide within the parenchyma cells which might significantly be influenced by various pedo-ecological parameters. newlineThe study also unfolded the clue that the physico-chemical properties of gel and acemannan polysaccharide were more prominently affected with the change of plant species than with the treatments of soil pH and moisture supplement
