Stabilization Mechanism of Colloidal Suspensions by Gum Tragacanth: The Influence of pH on Stability
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...
متن کاملAntinociceptive activity of Astragalus gummifer gum (gum tragacanth) through the adrenergic system: A in vivo study in mice
BACKGROUND In Iranian traditional medicine, gum obtained from Astragalus gummifer and some other species of Astragalus was used as analgesic agent. OBJECTIVE In this study, we investigated the antinociceptive effect of several concentrations (125, 250, and 500 μg/kg body weight) of Astragalus gummifer gum (AGG) on thermal and acetic acid induced pain in mice. MATERIALS AND METHODS AGG was d...
متن کاملEffect of Dispersed Phase Volume Fraction on Physical Stability of Oil-in-Water Emulsion in The Presence of Gum Tragacanth
Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
متن کاملInvestigating the effect of Nanofibers made of Gum Tragacanth with Ofloxacin on burn wounds in wet conditions in rat
Introduction: Gum Tragacanth (GT) obtained from Astragalus gossypinus is one of the most widely used natural gums which has found applications in many areas because of its attractive features such as biodegradability, nontoxic nature, natural availability, moisture absorption and creating a network of Hydrocolloid. It also has properties like maintenance and delivery of drugs, higher resistance...
متن کاملEffect of Irradiated Gum Tragacanth on Rheological Properties of Oil in Water Emulsion
Background: Emulsions are thermodynamically unstable systems that can be kinetically stable by adding substances known as emulsifiers and/or thickening agents. By respect to the functional properties of gum tragacanth (GT), and its breakage probability during irradiation treatment, the major aim of this study was to investigate the stability of oil in water emulsion in the presence of different...
