Studies on the Chemical Composition of Salai Gum


     

   Subscribe/Renew Journal


The oleo gum resin from Salai (Boswellia serrata) COnsists of 23.5% gum, 55% oil and 55% resin. The gum portion mainly contains D.galactose (46.22%), D-arabinose (11.66%) and 4-D-methyl glucuronic acid alongwith minor quantities of D.mannose and D-xylose in the molecular architect. The gum on methylation and subsequent hydrolysis of methylated product yielded a complex mixture of O-methyl sugars. The main type of linkages in between galactose units were found to be 1→3 and 1→6.
