Tragacanth is a gum commonly found in the sap of various Middle Eastern legumes. It is commonly used as freezing-embedding medium for tissue preservation. Gum tragacanth is an exudate gum from species of Astragalus trees mainly grown in Iran and Turkey. Tragacanth finds applications as an effective emulsifying and thickening agent in the food and pharmaceutical industries. The gum is a slightly acidic salt consisting of two fractions namely the water soluble tragacanthin and the fraction bassorin which swells in water to form a gel. Water soluble tragacanthin is reported as a branched arabiogalactan which is soluble in 70% ethanol. The acidic bassorin has a chain of (1,4)-linked a-D-galacturonic acid units some of which are substituted at O-3 with β-D-xylopyranosyl units and some of these being terminated with galactose or fucose.
