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 (C(18:1)) 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.
从印度森林中采集的诃子种子被探索作为生物柴油合成的替代生物资源。诃子种子的油产量约为 31%（干重基础）。诃子籽油的脂肪酸组成显示出油酸（C(18:1)）甘油酯的优势（61.5%），以及亚油酸（18.5%）和棕榈酸（11.6%）甘油酯。对油进行了提取和理化性质评估，与麻疯树、向日葵、大豆和油菜籽油进行了比较。在甲醇钠催化剂存在下，用甲醇对诃子油进行了酯交换。根据生物柴油的 ASTM D-6751 规范，将合成的甲酯的理化性质与麻疯树、向日葵、大豆和油菜甲酯进行了比较。将合成的诃子甲酯以 5-20%的比例混入柴油中，并根据 IS 1460 规范评估了关键理化性质，发现根据特定标准评估的性质符合要求。该研究表明诃子籽油作为生物柴油潜在资源的可能性。
