Percent yield of fatty acid ethyl esters at 1:4 SPSO-to-ethanol molar ratio. Salvadora biodiesel obtained from the most productive SPSO-to-ethanol molar ratio (1:4) was analyzed through gas chromatography to find out the composition of major ethyl esters in the biodiesel yield. Ethyl laurate was found in the lowest quantity (6%) followed by the highest percentages of ethyl myristate and ethyl palmitate (19% each). The quantity of ethyl oleate ranged up to 16%. Therefore, mostly esters of medium- and long-chain fatty acids were found in Salvadora biodiesel at 1:4 molar ratio. The graph was plotted in Microsoft Excel version 365 Pro Plus. Experiments were performed in duplicate
