Abstract

Essential oil chemical constituents of Jatropha curcas were analyzed for the effect of lead (Pb) on in vitro shoots. A total of 36 and 30 compounds obtained from in vitro and Pb treated shoots. The four compounds were ?-copaene, ?-bourbonene, T-muurolol and lauric acid increased parentage in Pb treated in vitro shoots. Lead treated in vitro shoots resulted in production of 21 new compounds and increased percentage of fatty acid, alkanes and aldehyde.
