background: the excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. gum tragacanth (gt) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. despite,  its desirable prop...

Objective: To investigate the comparative wound-healing potency of aqueous and methanol leaf extracts of Vernonia arborea Hk. Materials and Methods: Excision, incision and dead space wound models were used to evaluate the wound-healing activity of Vernonia arborea Hk., on Swiss Wistar strain rats of either sex. In excision wound model, treatment was continued till the complete healing of the wo...

An acidic polyelectrolyte, gum tragacanth (GT) , was found to stabilize polystyrene latex particles due to a steric stabilization mechanism. The stability depends significantly on the pH of the solution. To elucidate the stabilization mechanism, a number of parameters, such as the adsorption isotherm, the zeta potential, and the conformation were measured as a function of pH. The adsorption iso...

plants gums, hydrophilic colloids, hydrocolloids, mucilages and hydrophilic polymers are compounds that can produce gel. coating materials which applied on food products increased shelf life of food by affecting water loss, gas exchange, oxidation process and decreasing the food spoilage and affect shelf life of food products. coating material could carry antioxidant, antibacterial and/or other...

Due to early deterioration of banana in drying process, almond, quince seed, and tragacanth gums as edible coatings were determined. For this purpose, banana slices were coated in 0.7% solution of each gum and one group remained uncoated as the control. The samples were examined at specific times considering the weight loss, color analyzing (a*, b*, and L*) through the method computer vision, c...
