Abstract: Terminalia belerica seeds, collected from Indian forests, were explored as an alternate bioresource for biodiesel synthesis. The oil yield of T. belerica seed is about 31% (dry weight basis). The fatty acid profile of T. belerica seed oil shows predominance of oleic acid (C18:1) glycerides (61.5%) along with linoleic (18.5%) and palmitic (11.6%) glycerides. Oil was extracted and evaluated for physico-chemical properties vis-a-vis jatropha, sunflower, soybean and rapeseed oil. T. belerica oil was transesterified with methanol in the presence of sodium methoxide catalyst. The physico-chemical properties of synthesized methyl ester were compared to jatropha, sunflower, soybean and rapeseed methyl esters as per ASTM D-6751 specification of biodiesel. Synthesized T. belerica methyl ester was also blended in diesel at 5–20% ratios and evaluated for key physico-chemical properties as per IS 1460 specification and found to meet in properties evaluated as per specific standards. The study revealed the possibility of T. belerica seed oil as potential resource of biodiesel. [Copyright &y& Elsevier]
