Phytochemical studies were carried out on the plant parts of Jatropha curcas (L.) and Azadirachta indica (A. Juss) found in the South Eastern parts of Nigeria with a view to highlighting their pre-existing secondary metabolites which have varieties of biological activities attributed to them. Qualitative and quantitative analysis of seven secondary metabolites (alkaloids, tannins, saponins, fla...

Jatropha curcas is a herbal preparation used in the tropics for the treatment of threatened abortion and related problems associated with pregnancy. The Stem bark of Jatropha curcas is used ethno medicinally in Nigeria especially in the eastern part of the country for the treatment of infertility and spontaneous abortion (miscarriage). The present study was undertaken in order to validate the f...

To study oil contents and fatty acid composition among the samples of Jatropha curcas L. seeds were collected from Dehradun, Uttarakhand. Soxhlet extraction method and gas chromatography (GC) were employed to determine the oil contents of Jatropha seeds and the fatty acid composition of Jatropha oil. The seed oil contents (dry basis) was 46.27% .Physicochemical properties shows acid value (36.4...

BACKGROUND The potential biofuel plant Jatropha curcas L. is affected by larvae of Archips micaceanus (Walker), a moth of the family Tortricidae. The hybrid Bacillus thuringiensis (Bt) δ-endotoxin protein Cry1Ab/1Ac confers resistance to lepidopteran insects in transgenic rice. RESULTS Here, we report the production of a marker-free transgenic line of J. curcas (L10) expressing Cry1Ab/1Ac usi...

A vigorous interspecific hybrid has been obtained from cross-polliniations between two tropical woody species of Jatropha, J. curcas and J. integerrirna, which belong to differ...

When Jatropha costaricensis Webster & Poveda was described from Guanacaste, Costa Rica, some years ago (Webster & Poveda, 1978), it was predicted that other xeric relict taxa might be discovered elsewhere in Central America. Recent botanical exploration in Nicaragua has disclosed not only a number of new populations of Jatropha podagrica Hook. in rocky areas in Dept. Esteli, but also on basalti...

In this study, Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. To establish the optimum conditions for biodiesel production, effects of certain factors were investigated, these factors are oil-to-methanol molar ratios (1:4 1:8), KOH catalyst concentrations (0.5 1.5% w/w oil), reaction temperatures (50 70oC), and reaction times (55 90minutes)....

Original scientific paper Renewable sources should be preferred by a modern society and this should be done not only in the areas of material engineering. Jatropha curcas L. is a plant with a high potential with many technologically utilized parts among which seeds most of all. The seeds of the plant serve for the pressing of oil. During this technological process worse utilizable commodities s...

91 10.4155/BFS.09.4 © 2010 Future Science Ltd Jatropha curcas L. (further referred to as Jatropha) is a rapidly emerging biofuel crop currently attracting a lot of interest and investments [1]. This stem-succulent [2] deciduous tree or shrub produces seeds rich in toxic oil (27–40% [3]). The oil can be extracted easily with techniques of different sophistication levels [4,5]. The crude Jatropha...

Propagation potentials of stem cuttings of different physiological ages and genotypes of physic nut (Jatropha curcas L.) were studied at UKM, Malaysia. Stem cuttings of the different physiological ages (hardwood, semi hardwood and soft wood) taken from five selected genotypes of Jatropha were planted in soil media (top soil). Data were collected on the attributes of the stem cuttings and then a...
