Pharmacognostic Studies of the Jatropha Curcas Leaves

The J. curcas is considered as a biofuel plant, but the leaves are traditionally used as an antiinflammatory and anticoagulant. In present investigation, the detailed pharmacognostic study of J. curcas leaf is carried out to lay down the standards which could be useful in future experimental studies. The study includes macroscopy, microscopy, preliminary phytochemical screening and physicochemi...

Effects of Crude Oil Contaminated Soil on Biomass Accumulation in Jatropha curcas L. Seedlings

A study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation inJatropha curcas seedlings in Asaba, Delta State, Nigeria. Oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. The trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. Results showed that contamination...

CORROSION INHIBITIVE PROPERTIES OF EXTRACT OF JATROPHA CURCAS LEAVES ON MILD STEEL IN HYDROCHLORIC ACID ENVIRONMENT

Jatropha curcas leaves extract was tested as a green corrosion inhibitor for mild steel in aqueous hydrochloric acid solution using gravimetric and thermometric techniques. The results reveal that the inhibition efficiency vary with concentration of the leaf extract and the time of immersion. Maximum inhibition efficiency was found to be 95.92% in 2M HCl with 0.5 g/l concentration of the extrac...

Antioxidant activity of flavonoids from leaves of Jatropha curcas

The objective of this study was to characterize the antioxidant properties of ethanol extracted from leaves of Jatropha curcas and to determinate the compounds. The IC50 values of DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) were found to be 7.47 and 6.6 μg/ml, respectively, for the extracts. The reducing power of the ex...
