Gum tragacanth derived from the plant "goat's horn" (Astragalus sp.) has a long history of use as a stabilizing, viscosity-enhancing agent in food emulsions. The gum contains pectinaceous arabinogalactans and fucose-substituted xylogalacturonans. In this work, gum tragacanth from Astragalus gossypinus was enzymatically depolymerized using Aspergillus niger pectinases (Pectinex BE Color). Th...

The present study was undertaken to develop oral sustained release tablets of metoprolol tartrate using natural hydrophilic matrix formers (xanthan gum and tragacanth). Sustained release matrix tablets of metoprolol tartrate were prepared by using different ratios of drug, xanthan gum and tragacanth. Microcrystalline cellulose (MCC) was used as diluent. The polymer was incorporated into a matri...

Medicinal plants are one of very valuable rescores in wide range of world and Iran natural resources. Herbal medicines against chemical and synthetic drugs have bad effects and minor side effects and or are completely harmless. Interest in ethnobotany has increased dramatically in recent years. Medicinal folklore over the years has proved to be an invaluable guide in present day screening of dr...

The binary mixture tablets of papain and microcrystalline cellulose (MCC), dicalcium phosphate dihydrate (DCP), carrageenan, tragacanth, and agar were prepared by direct compression. Carrageenan, tragacanth, and agar provided maximum protection to enzyme activity compared to MCC and DCP. However, stability studies indicated highest loss of enzyme activity with carrageenan, tragacanth, and agar....

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...

background & aim: tragacanth is a natural gum obtained from the dried sap of several species of middle eastern egumes of the genus astragalus, that is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides. tragacanth is used in pharmaceutical and foods industries as an emulsifier, thickener, stabilizer, and texturant additive. sponge cake is one of the most popular bakery...

The effects of different hydrocolloids on the gelatinisation behaviour of hard wheat flour were investigated. Influence of guar, xanthan, Arabic, carboxy methyl cellulose (CMC) and tragacanth gums on wheat flour was studied using micro viscoamylograph. It was found that all hydrocolloids except tragacanth greatly modified the gelatinisation properties of wheat flour. Guar and xanthan significan...
