Jatropha gossypifolia L. (Euphorbiaceae) is a plant widely used in the treatment of type 2 diabetes mellitus (T2DM), but there are few scientific reports validating its activity in this area. In this work and through a bioguided assay, a crude extract stimulated glucose uptake in C2C12 myotubes up to 30%, thereby reducing insulin resistance induced by fatty acids compared to the basal control. ...

Jatropha hulls were successfully for the first time used as raw materials for the production of 2,3-butanediol via dilute sulfuric acid hydrolysis and fermentation with Klebsiella oxytoca. Two-step hydrolysis was used to effectively hydrolyze the hulls at 150°C after pretreatment. In the first-step, hemicellulose was hydrolyzed under mild conditions (0.5h, 1.5% acid) to avoid secondary decompos...

The present study deals with the enzymatic synthesis of biodiesel by transesterification of Jatropha oil (Jatropha curcas L.) with ethanol in a solvent-free system. Seven commercial lipase preparations immobilized by covalent attachment on epoxy-polysiloxane-polyvinyl alcohol composite (epoxy-SiO2-PVA) were tested as biocatalysts. Among them, immobilized lipases from Pseudomonas fluorescens (li...

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...

BACKGROUND Transesterification of Jatropha oil was carried out in t-butanol solvent using immobilized lipase from Enterobacter aerogenes. The presence of t-butanol significantly reduced the negative effects caused by both methanol and glycerol. The effects of various reaction parameters on transesterification of Jatropha oil were studied. RESULTS The maximum yield of biodiesel was 94% (of whi...

Diminishing of conventional fuels and hysterical vehicles emission leads to deterioration of the environment, which emphasize the research to work on biofuels. Biofuels from different sources attract the attention of research due to low emission and biodegradability. Emission of carbon monoxide, carbon dioxide and H-C reduced drastically using Biofuels (B-20) combustion. Contrary to the convent...

Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between these two biodiesel pathways compared to fossil diesel, by taking into account possible uncertainties. The geographical location of this study i...

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...

Introduction: Stroke is one of the diseases that cause death and impact serious health problems. The inflammatory response appears in ischemic stroke will affect progression stroke. This study examines ethanol extract Jatropha leaves (Jatropha curcas L.) as a gel compress preparation post-ischemic patients. Methods: research design was experimental with randomized post-test-only control group d...
