Abstract:
Buchanania lanzan Spreng., a natural plant polysaccharide, commonly known as char, achar, piyar, chirongi and pre-dominantly the trees are available in the States of Chhattisgarh, Jharkhand, Madhya Pradesh and in Varanasi and Mirzapur districts of Uttar Pradesh. During last two decades plant polysaccharides/natural polymeric materials have evoked tremendous interest due to their diverse pharmaceutical applications such as diluents, binders, disintegrants, bio-adhesives, thickeners, emulsifiers, stabilizers, gelling agents as also in cosmetics, textiles, paints and paper-making etc. Many natural polysaccharides have been successfully used in sustained drug release because of their well-known non-toxicity, biodegradability, biocompatibility, biosafety, sustainability and unique physico-chemical properties, often at very low costs, as compared to their synthetic counterparts. Further, water-soluble polysaccharides certainly have enormously large and broad applications in both food and non-food industries. The present paper reports the thermal behaviour of Buchanania lanzan gum exudates, collected from different places, using various parameters i.e. Differential Scanning Calorimetry (DSC), Differential Thermal Analysis (DTA), Thermo-gravimetric Analysis (TGA), Fourier Transform-Infra Red (FTIR) and Particle Size Analysis, as thermal analysis gives information about changes in material properties as function of temperature. The TG thermograms for all the gum samples showed three-stage decomposition. The DSC thermograms of gums showed glass transitions ranging from 80.93 to 91.96 oC. The FTIR spectrum of Buchanania lanzan gum exudates, collected from different places exhibited the typical bands and peak characteristic for the gums. The particle size analysis of gum samples exhibited d50 values ranging from 56.50 to 254.2 μm.
