Abstract:
The objective of the present work was to isolate and characterize polysaccharide from fruits of Cordia dichotoma G. Forst. (Family Boraginaceae). Polysaccharide was isolated by using 1% Hydrochloric acid solution. The isolated polysaccharide was tested for physicochemical characteristics such as solubility, pH (1% w/w in water), swelling capacity, loss on drying, ash value, bulk and tapped density, Carr's capacity, Hausner's ratio and angle of repose. Also isolated polysaccharide was characterized by Differential scanning colorimeter (DSC), Estimation of total sugar content, Rheological study and infrared spectroscopy (FT-IR). The isolated mucilage showed positive results for Molisch's test and negative for Ruthenium red test which indicated presence of carbohydrate and gum. The result of physicochemical characteristics reveals that isolated Cordia dichotoma polysaccharide possesses good flow properties. The total polysaccharide content of Cordia dichotoma polymer isolate was found to be 86.24% (w/w). From this study it can be concluded that the polysaccharide isolated from Cordia dichotoma fruits has the required properties and could be used as an excipient for pharmaceutical dosage forms.
