Résumé
Jatropha curcas L. is a multipurpose shrub with a variety of applications and enormous economic potentials for its seed oil, which can be converted into biodiesel- an alternative to petro-diesel. It aims to overcome energy crisis problem and also to reduce environmental changes. The fact that the oil of J. curcas cannot be used for nutritional purposes without detoxification makes its use as an energy source for fuel production very attractive. Oil content of Jatropha curcus L was subjected to various physicochemical parameters. The chemical parameters include determination of free fatty acids, peroxide value, Iodine value, saponification value, various physiological analysis of Jatropha curcus L plant was also carried out in order to estimate the presence of total content of chlorophyll. By considering all the above parameters the present study reveals that the Jatropha curcus L l plant is good for production of better quality of biodiesel.
