Jatropha curcas is a multipurpose plant with many attributes and considerable potential. It is a tropical plant that can be grown in low or high rainfall areas and can be used to reclaim land, as a hedge or as a commercial crop. Now days the cases of Jatropha poisoning are rare, but due to its high toxic value in the presence of toxins like phorbol esters, the case studies in homicidal, suicidal or accidental cases become significant. For identification of Jatropha curcas constituents, an attempt has been made in the present study to identify phytochemicals, amino acid, saponins, phyto sterols, glycosides, anthraquinones, flavonoids and tanins. These were examined by various chemical colour tests and phorbol ester was examined by thin layer chromatography.
The extracted oil from the leaves and seed part was studied along with standard oil using two different solvents and their Rf values were also studied. For visualization of the spots, the plates were sprayed with sulphuric acid to develop coloured spots, which were then studied by UV in the range of 254-365 nm.
