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...

The objective of present study was to determine appropriate fruit harvesting stage for Jatropha curcas L. for getting seeds with good oil content and better germination. The seeds separated from the fruits harvested at yellow capsule stage (C2) showed maximum germination efficiency, both under laboratory and nursery conditions whereas seeds separated from the fruits harvested at brownish black ...

Longicorn beetle, Acanthophorus rugiceps Gahan (Coleoptera: Cerambycidae), is reported for the first time as a confirmed host on physic nut, Jatropha curcas L. (Malpighiales: Euphorbiaceae), from India, causing extensive damage to roots. Plants of three years age and above were prone to attack by this pest. In a six year study beginning in 2005, about 11.3 percent of plants in a 16.25 acre phys...

Developing a protocol for somatic embryogenesis (SE) adult mother plants of Jatropha curcas, aids to overcome problems such as harvesting time and an uneven yield, providing the opportunity propagate proven elite genotypes. Until now, several authors have achieved SE in J. curcas using different explants, however, none these protocols been used plant material. Furthermore, challenge overcoming ...

The objective of this research is to produce the low-cost activated carbon from Jatropha curcas L. by chemical activation using zinc chloride ZnCl2. The effects of the impregnation ratio on the surface and chemical properties of activated carbon were investigated. The impregnation ratio was selected at the range of 1:1-10:1 for investigation. The optimum conditions resulted in an activated carb...

Thrombosis is one of the leading cause of thromboembolic disorders affecting million persons worldwide. Several plants used for the treatment of thromboembolic diseases in different systems of traditional medicine have shown anticoagulant/antithrombotic activity and such plants claimed in the traditional system still remain to be scientifically investigated. The review explored various herbal d...

Jatropha curcas is a woody-shrub species of the Euphorbiaceae family that widely distributed in tropical and subtropical areas. The great interest its cultivation lies potential for achieving elevated yields high-quality oil. Another characteristic makes J. promising ability to produce green energy even high-salinity soils. For commercial be considered effectively competent withstand these cond...

Jatropha curcas L. (Euphorbiaceae) is a plant species widely present in tropical and subtropical regions that have been studied mainly for its potential biofuel production; it also known toxic substances. To explore use as an insecticide, we the effect of seed extract from green fruit oils mature dried J. on aphid Myzus persicae (Hemiptera: Aphididae). Seven concentrations extracts different ma...

Plant poisoning is not an uncommon problem in Sri Lanka. A hospital based prospective study showed that Jatropha curcas, Ricinus communis, Dieffenbachia, Adenia palmata, Amanita phalloides and Thevetia peruviana are common poisonous plants implicated in poisoning among children in Sri Lanka. [1]. In the past, deliberate ingestion of yellow oleander seeds (Thevetia peruviana) was a common method...

The crude methanol extract of Jatropha curcas leaves exhibited activity against Staphylococcus aureus, Bacillus subtilis, Mycobacterium phlei, Candida albicans, and Trichophyton mentagrophytes but was inactive against Escherichia coli, Pseudomonas aeruginosa, and Saccharomyces cerevisiae. In a bioassay-directed fractionation, two new phorbins were isolated and analysed by spectroscopic methods....
