Abstract
Gum tragacanth is of the most important herbal gums extracted from Astragalus gossypinus Fischer. Iran is the most important producer of tragacanth and nowadays it is being used in various industries like food, health care services and pharmaceutics. Since economic evaluation of tragacanth is performed based on its quality, studying chemical combinations of gum tragacanth and detection of its habitats are very important. In this study, gum tragacanth from six habitats were collected in west of Isfahan province and most important combination of carbohydrate, Amino acid and inorganic elements were detected and compared. Results showed that Arabinose had the highest amount of sugar in gum tragacanth. Overall, 9 types of Amine acids were identified and among them hydroxy prolin and mationin were recorded as the highest and the lowest amount respectively. Also among the measured elements, calcium and phosphor had the highest percentage and nitrogen had the lowest percentage.
