Rhazya stricta Decne seed oil as an alternative, non-conventional feedstock for biodiesel production

Description
Summary:Rhazya stricta Decne (R. stricta) is a hardy, drought-resistant, and arid land plant that is widely distributed from the Middle East to South Asia. The aim of this study was to evaluate the use of R. stricta seed oil as an alternative source of triacylglycerols that may be suitable for the synthesis of biodiesel. The oil content of the seeds was approximately 14% and was mainly composed of the fatty acids linoleic (60.95%) and oleic (25.48%) acid. R. stricta methyl esters (RSME) were prepared by a base-catalyzed transesterification reaction. The conversion rate of the triacylglycerols to the corresponding methyl esters was determined by super(1)H-NMR to be approximately 97%. This study showed that the fuel properties of the RSMEs are comparable to other vegetable oil methyl esters that are commonly used as biodiesels. R. stricta plantations will therefore be suitable for promoting sustainable agriculture and for producing biodiesel with viable prices in arid and semi-arid regions throughout the world.
