Texte intégralRésumé :
This study was conducted to assess the phytochemical, antistaphylococcal and antioxidant properties of the leaf and stem bark of Jatropha curcas and Jatropha gossypifolia. Ethanolic extract of the leaf and stem bark of Jatropha curcas and Jatropha gossypifolia was obtained using standard methods. Qualitative and quantitative phytochemical properties of theJatropha plant was assessed using standard methods. Antistaphylococcal and minimum inhibitory concentration of the extracts were assessed against Staphylococcal aureus obtained from different sources using agar diffusion method. Ferrous ion and hydroxyl radical scavenging activity of the extracts were also determined using standard methods. Quantitative phytochemical screening revealed that the distribution of phytochemicals in the two Jatropha species do not follow a regular trend. However, saponin was highest in Jatropha curcas stem bark (35.64 mg/g) while Jatropha gossypifolia stem bark and leaf have the highest flavonoid (31.35 mg/g) and alkaloids (23.20 mg/g) respectively. The antistaphylococcal effect of the combined extract was higher and significantly different (P≤0.05) than when used singly. The highest antistaphylococcal effect (19.83mm) was recorded for the combination of Jatropha curcas and Jatropha gossypifolia leaf (JCL and JGL) against Staphylococcus aureus obtained from blood. Antioxidant assay of extracts revealed a concentration dependent effect. The antioxidant activities of the extracts vary from one extract to the other. The results obtained from this study indicates that bioactive compounds present in Jatropha curcas and Jatropha gossypifolia can be exploited as source of effective antistaphylococcal and antioxidant compounds.

La baisse de la fertilité des sols due à la mauvaise gestion des terres et l’utilisation excessive des engrais chimiques a motivé le regain d’intérêt dans la recherche de fertilisants organiques respectant l’environnement pour un développement durable. Pour évaluer l’efficacité agronomique des litières de Jatropha sur la production de la tomate, une étude a été conduite en champs dans des pots de 20 cm de diamètre. Le dispositif expérimental est un bloc de Fischer randomisé avec un total de 64 pots (4 traitements x 4 répétitions x 4 unités expérimentales). Les résultats ont montré que les litières de Jatropha curcas et Jatropha gossypifolia ont amélioré la croissance et le développement (le diamètre et la ramification de la tige, le nombre de feuille et de fruits ainsi que la masse des fruits) de la tomate par rapport au témoin. La litière de Jatropha curcas a induit une large amélioration de la masse des fruits (33,09 g) par rapport aux autres traitements : le témoin (19,99 g), la litière de Jatropha gossypifolia (20,44 g) et l’engrais chimique (24,02 g).

This study aims to explain the use (biofuel) and toxicity of J. curcas. This study is based on an online literature study on Google Scholar using the keywords J. Curcas and toxicity of J. curcas. Inedible vegetable oil (biodiesel), such as castor oil is considered a future raw material because it is a non-edible oil, does not cause food versus fuel conflicts. The potential of J. curcas as a biofuel is related to the oil content consisting of saturated fatty acids, palmitic acid, stearic acid and unsaturated fatty acids, oleic acid, and linoleic acid. Poisoning due to side effects of J. curcas seeds occurs in humans, especially children and also in the environment. Symptoms of poisoning caused by J. curcas can be analyzed through clinical signs and the effects vary greatly, depending on the concentration, frequency, part eaten and the processing process. Accidentally ingested J. curcas seeds cause clinical syndromes such as restlessness, severe vomiting, and dehydration. Curcacycline A and curcin compound has been successfully identified from J. curcas with antitumor activity. The potential of J. curcas as an antitumor needs to be studied further to find alternative treatments for cancer and tumors.

 One of the successful chemical modifications that improves the physico-chemical properties of vegetable oils is epoxidation, Jatropha oil has potential as a raw material for industrial applications because it is renewable and inedible. The epoxidation was carried out in Jatropha curcas L. oil from the province of Manabí, Republic of Ecuador, through the reaction of formic acid with hydrogen peroxide. The parameters of the crude and epoxidized oil are determined through the standards of the American Society for Tests and Materials (ASTM) for acid number ASTM D-664, density ASTM D-1298, Dynamic and kinematic viscosity ASTM D-445, Saponification index ASTM D-94, Moisture content ASTM D-2709, European Standard (EN) for iodine number EN 14111, International Organization for Standardization (ISO) for peroxide number ISO 3960 and American Society of Oil Chemists (AOCS) for Percentage of Acidity AOCS with the official Method Ca 5a-40, respectively. The results show that the epoxidized Jatropha curcas L. oil has a lower iodine value (27.48 g I2 / g fat) and peroxide value (158.28 mEq O / Kg fat), and a higher acidity index (34.92 mg KOH / g oil), acidity (17.55%), density (1.01 ± 0.01 g / cm3), dynamic and kinematic viscosity at 100 and 40 ºC among other properties. From the analysis it is concluded that this is an effective method to improve the properties of Jatropha curcas L. oil and demostrates the usefulness of epoxidized Jatropha curcas L. oil for the formulation of biodegradable lubricating greases.

Texte intégralRésumé :
Objectif : L’objectif est de contribuer à enrichir la gamme d’espèces végétales utilisables dans la restauration et la valorisation des terres salées. Méthodologie et résultats : Dans 3 essais indépendants et selon un dispositif complètement aléatoire, des plants de Casuarina equisetifolia, Gossypium hirsutum et Jatropha curcas ont été arrosés avec une solution de NaCl de concentrations variant de 0 à 23,36 g.l-1 et suivis pendant deux mois. Ensuite, ils ont été soumis à un test de toxicité de concentrations 8 fois plus élevées. Les résultats montrent que les concentrations utilisées au début sont moins néfastes pour la croissance et la production de biomasse chez G. hirsutum et C. equisetifolia que chez J. curcas. Elles augmentent la production de litière chez J. curcas. Conclusion et application des résultats : Les résultats obtenus peuvent expliquer qu’entre 46,72 et 186,88 g.l-1, la solution de NaCl fut létale (44 à 100% de mortalité) pour C. equisetifolia et G. hirsutum mais pas pour J. curcas qui n’a enregistré aucune mortalité. Ainsi, jusqu’à une concentration de 23,36 g.l-1, les trois espèces réagissent différemment. De ce fait, il en ressort que G. hirsutum et C. equisetifolia peuvent être utilisés pour la restauration et la valorisation de superficies de terres salées. Par contre, à partir de 46,72 g.l-1, le choix de J. curcas s’impose. Mots-clés : Salinisation, restauration, Casuarina equisetifolia L., Gossypium hirsutum L., Jatropha curcas L., valorisation. ABSTRACT Objective: To contribute to the range of plant species that can be used in the restoration and reclamation of saline lands. Methodology and results: In three (3) independent trials and in a completely randomised design, Casuarina equisetifolia, Gossypium hirsutum and Jatropha curcas young plants were sprayed with NaCl solution at concentrations varying from 0 to 23.36 gl-1 and monitored for two months. Subsequently, these plants were submitted to a toxicity test with concentrations eight times higher. Results show that first two months salt solutions are less harmful for growth and biomass 16521 Faye et al., J. Appl. Biosci.

They have significant effects on litter production, which increases in J. curcas. Conclusion and application of results: The study results may explain why between 46.72 and 186.88 gl-1 NaCl solution is lethal (44 to 100% mortality) for C. equisetifolia and G. hirsutum and not for J. curcas, which does not record mortality. Thus, up to 23.36 gl-1 NaCl concentration, the three species react differently. Thereby, G. hirsutum and C. equisetifolia can be used for the restoration and enhancement of salty areas. On the other hand, from 46.72 g.l-1, it is essential to choose J. curcas. Key words: Salinization, restoration, Casuarina equisetifolia L., Gossypium hirsutum L., Jatropha curcas L., valorisation.

Texte intégralRésumé :
A pot-grown experiment was conducted to investigate the effect of limited irrigation on growth, storage water amount of every organ and water use of Jatropha curcas L.seedlings. Four watering treatments were designed in the study, i.e. (W1: 0.3θf，W2: 0.5θf，W3: 0.7θf，W4: 0.9θf，θf is the field capacity). Results show that Jatropha curcas L.seedlings has the higher resistance ability to drought-stress, it can survival in lower soil moisture (0.3θf) , and has certain growth potential. Dry mass of every organ in plant shows that shoot＞branch and master rod＞leaf＞root＞petiole. Storage water capability of unit dry mass for every organ in plant shows that petiole＞branch and master rod or shoot＞leaf＞root. Compared to W4 treatments, W2 reduced irrigation water by 27.1%, mean leaf area of Jatropha curcas L.seedlings for W2 reduced by 25.8%, but root-shoot ratio increased by 6.1%, meanwhile, mean storage water capability of unit root, lateral branch and master rod, leaf, shoot and total plant dry mass of Jatropha curcas L.seedlings for W2 increased by 15.4%，1.3%，7.4%，0.6% and 1.8%, respectively. But mean root, shoot and total plant dry mass accumulation of Jatropha curcas L.seedlings for W2 only reduced by 11.4%、17.7%、15.8%, respectively, therefore, irrigation water use efficiency and total water use efficiency of Jatropha curcas L.seedlings for W2 increased by 15.5%，14.9%, respectively. It is clear that W2 treatment not only increased water use efficiency, but increased regulation storage water capability, thus W2 treatment’s Jatropha curcas L.seedlings improved water regulation and controlled water balance capability and resistance ability to drought-stress.

Texte intégralRésumé :
Along with the awareness to obtain quality plant products, the use of plant-based insecticides is increasingly being used. One of the plants used as a plant-based insecticide is Jatropha curcas L. (Jarak pagar) because it contains toxic ingredients to kill cabbage caterpillar pests (Crocidolomia binotalis). This study aims to determine the effectiveness of Jatropha curcas L. on the mortality of Crocidolomia binotalis cabbage caterpillars. The research method used was a Completely Randomized Design (CRD) 7 × 3, consisting of seven treatment concentrations (0,000 ppm, 10,000 ppm, 20,000 ppm, 30,000 ppm, 40,000 ppm, 50,000 ppm, 60,000 ppm), with three replications. Observations were made at 24, 48, 72, 96, 120, 144 hours after application (HAA) of Jatropha. The research activities were carried out in two stages, namely 1) the extraction stage of Jatropha curcas L. seeds and the breeding of the Crocidolomia binotalis test larvae and 2) the testing stage with seven concentration levels of Jatropha curcas L. extract as a plant-based insecticide. ANOVA test showed that the treatments of Jatropha curcas L. extract gave the death effect on larvae [F-count > F-table (116.8 > 2.37)]. Dead larvae change color to black and their body shape will curve. The fastest larval death occurs 24 HAA, with a concentration of 40,000 ppm, which is 50%. At lower concentrations (30,000 ppm), which can kill larvae up to 50%, occurs 120 HAA. With a concentration of 50,000 ppm, 90% of larvae can be killed occurring 96 HAA.

Texte intégralRésumé :
The study was conducted to compare the proximate composition of bacterial (Psuedomonas aeruginosa) treated and untreated Jatropha curcas kernel cake (JKC). Jatropha curcas L. is one of the toxic species of Jatropha similar in shape to plants in Euphorbiaceous families in plant kingdom. It kernel after oil extraction have been shown to be a promising animal feed cake with appreciable crude protein content, therefore method of detoxifying the kernel cake should be intensify in other to improve it feeding value. Dried Jatropha curcas kernel cake was obtain from University of Ilorin Jatropha plantation unit. It was treated by soaking in petroleum ether (24 hours), air dried (three days) and then autoclave for 15 minutes at 121OC before fermented with the spores of bacteria (Pseudomonas aeruginosa) for nine days. Standard procedures (AOAC) were employed to analyse the treated and untreated Jatropha curcas kernel cake samples. The results showed that the treated sample significantly (p<0.05) had higher content of dry matter, ash and nitrogen free extract while the untreated had lower values. On the other hand the untreated sample significantly (p<0.05) had higher values of crude protein, crude fibre and ether extract while the treated sample had lower. It can be concluded that inoculation of Jatropha curcas kernel cake with bacteria (Pseudomonas aeruginosa) will improve dry matter, ash and nitrogen free extract contents. 
 
 
 
 
 L’étude a été menée pour comparer la composition immédiate des bactéries (Psuedomonas aeruginosa) traité et non traité de tourteau de noyau de Jatropha curcas (TNJ). Jatropha curcas L. est l’une des espèces toxiques de Jatropha de forme similaire aux plantes des familles Euphorbiacées du règne végétal. Il a été démontré que le noyau après extraction de l’huile est un tourteau prometteur pour l’alimentation animale avec une teneur appréciable en protéines brutes. Par conséquent, la méthode de détoxification du tourteau de noyau doit être intensifiée dans d’autres pour améliorer sa valeur alimentaire. Le gâteau de noyau de Jatropha curcas séché a été obtenu auprès de l’unité de plantation de Jatropha de l’Université d’Ilorin. Il a été traité par trempage dans de l’éther de pétrole (24 heures), séché à l’air (trois jours) puis autoclavé pendant 15 minutes à 121°C avant de fermenter avec les spores de bactéries (Pseudomonas aeruginosa) pendant neuf jours. Des procédures standard (AOAC) ont été utilisées pour analyser les échantillons de tourteaux de noyau de Jatropha curcas traités et non traités. Les résultats ont montré que l’échantillon traité de manière significative (p < 0,05) avait une teneur plus élevée en matière sèche, en cendres et en extrait sans azote tandis que l’échantillon non traité avait des valeurs plus faibles. D’autre part, l’échantillon non traité avait significativement (p < 0,05) des valeurs plus élevées de protéines brutes, de fibres brutes et d’extrait d’éther tandis que l’échantillon traité en avait des plus faibles. On peut conclure que l’inoculation du tourteau de Jatropha curcas avec des bactéries (Pseudomonas aeruginosa) améliorera les teneurs en matière sèche, en cendres et en extraits libres d’azote.

Texte intégralRésumé :
Jatropha curcas is a plant of great economic importance that experiences high incidence of fungal attack. Misidentification of the fungal species is bound to occur with the use of traditional cultural methods where organisms are identified morphologically and/or microscopically. This study was carried out to isolate and identify the fungi associated with Jatropha curcas (L.) using both traditional/ cultural techniques and molecular methods. The fungi were isolated from diseased leaves and stems of J. curcas using both Standard Blotter and Potato Dextrose Agar (PDA) methods. DNA was extracted from the fungal isolates using Zymo Fungal/Bacteria DNA MiniPrep Kit. Amplification of the Internal Transcribed Spacer (ITS) regions of the fungal isolates was carried out using fungi universal primer pairs for ITS4 and ITS5. The amplicons were sequenced and the isolates were identified as Penicillium brevicompactum, Aspergillus sp., Botryosphaeria rhodina, Aspergillus nomius, Aspergillus tamarii, Rhizopus oryzae, Penicillium citrinum and Fusarium solani. Phylogenetic analysis was carried out to know the relationship between the isolates and other closely-related species in GenBank. Jatropha curcas is colonized by many fungal species some of which may be pathogenic to the plant, and molecular techniques pose the best alternative for accurate identification of these organisms.

Periodontal disease is characterized by inflammation as well as damage to the periodontal tissues, including the alveolar bone, cementum, gingiva, and the periodontal ligament. Aggregatibacter actinomycetemcomitans is the dominant bacterium in cases of periodontitis. Jatropha curcas plant is one of the ingredients that has been widely used for traditional medicine in the community, especially for the leaves. This plant is rich in active compounds such as alkaloids, tannins, phenols, flavonoids, and saponins, which are effective against gram-positive and gram-negative bacteria. This study aimed to determine the effectiveness of Jatropha extract (Jatropha curcas L.) as an antibacterial against Aggregatibacter actinomycetemcomitans in vitro.
 Methods: In vitro experimental studies. A total of 28 petri dishes contained bacterial colonies Aggregatibacter actinomycetemcomitans were used and divided into 7 test groups, treatment, and control groups. Obtained data were analyzed using SPSS program.
 Results: Jatropha extract treatment group with a concentration of 35% to 65% had optimal antibacterial abilities as the dose increased. This study also showed that at a concentration of 25%, Jatropha curcas extract did not have the antibacterial ability.
 Conclusion: Jatropha curcas extract has an antibacterial effect as the concentration of the extract increases againts Aggregatibacter actinomycetemcomitans.

Texte intégralRésumé :
Jatropha curcas L., a multipurpose oilseed plant, is very important for biodiesel production; it also has a wide range of bioactive compounds with medicinal properties and biocidal activity for control of crop pests and diseases. This review presents the state-of-the-art of the biocidal activity of J. curcas extracts. Chemical constituents such as phorbol esters are responsible for high bioactivity of J. curcas, due to their toxicity to humans and animals and to their high fungicidal and insecticidal activity. The fungicidal activity of these constituents may be due to destroy endoplasmatic reticulum and hyphae cell walls. The activity of these compounds on insect pest metabolism is well known, leading to an antifeedant effect, repellency, mating inhibition, oviposition inhibition or suppression and/or induction of infertile egg production, and inhibition of larva, nymph, and pupa development. Several studies have shown that although all organs of J. curcas plant are toxic, the degree of toxicity varies in accordance with the extract formulation, the nature of the active substance, the administration rate and procedure, and the individual sensitivity of pests and diseases. Thus, J. curcas stands out as a promising species for bioenergy purposes, as well as for control of pests and diseases that affect agriculture production.

The experimental design used was Completely Randomized Design (CRD) replicated three times. Physical and chemical properties of domestic sewage were investigated before and after the purification exercise. Treatments imposed included: the control culture (no alum and Jatropha), 10 mg/l of Aluminium Sulphate (alum) treatment, 80 mg/l of J. curcas treatment, 100 mg/l of J. curcas treatment and 120 mg/l of J. curcas treatment. The results showed that for the total dissolved solids, cultured tanks treated with 80 mg/l of J. curcas reduced the sewage concentration from 30.1 mg/l to 23.20 mg/l, Biological Oxygen Demand (BOD) was reduced from 30.55 mg/l to 30.10 mg/l, increased acidity from 5.33 mg/l to 5.66 mg/l, reduced alkalinity from 6.35 mg/l to 6.0 mg/l, reduced pH from 7.6 to 6.55, and likewise 10 mg/l of alum also reduced pH from 7.6 to 6.55. The cultured tanks treated with 120 mg/l of J. curcas performed best in reducing turbidity and Chemical Oxygen Demand (COD) of the sewage. The turbidity was reduced from 5.99 NTU to 5.6 NTU; 120 mg/l of J. curcas also reduced total hardness from 9.6 mg/l to 7.15 mg/l, total solids from 55.6 mg/l to 55.17 mg/l. Cultured tanks treated with 10 mg/l of alum reduced total dissolved solids from 30.1 mg/l to 24.30 mg/l, while those treated with 80 mg/l of J. curcas reduced it from 30.1 mg/l to 23.20 mg/l, 100 mg/l and 120 mg/l of J. curcas reduced it to 25.20 mg/l. Total suspended solids increased from 25.5 mg/l to 30.96 mg/l for 10 mg/l of alum, to 30.22 mg/l for 80 mg/l of J. curcas, 30.26 mg/l for 100 mg/l of J. curcas and 30.38 mg/l for 120 mg/l of J. curcas. Conductivity increased withion the study period from 525 μS/cm to 830 μS/cm for 10 mg/l of alum, to 590 μS/cm for 80 mg/l of J. curcas, 634 μS/cm for 100 mg/l of J. curcas and finally to 662 μS/cm for 120 mg/l of J. curcas. The results show that, within the reduction of BOD, pH, alkalinity and total solids, 80 mg/l of J. curcas performed best, while for reduction of COD and turbidity, 120 mg/l of J. curcas gave the best results.

Texte intégralRésumé :
The genetic transformation via pollen-tube pathway is an alternative method to overcome the constraints imposed by genotype specificity in transformation and regeneration in jatropha (Jatropha curcas L.) tissue culture. Therefore, it is necessary to establish important parameters for efficient genetic transformation of jatropha via pollen-tube pathway. The objective of the research was to study the efficiency of direct transformation of jatropha via pollen-tube pathway based on histochemical and molecular analysis. Solution of purified pCAMBIA1301 DNA plasmid carrying a hptII marker gene and a gus reporter gene with concentration level of 0.05, 0.25, 0.50 µg µl-1 were applied to stigma of flowers at 1, 2, 4, 7, 10 h after pollination. Seedling of IP3A, IP3P and JcUMM18 jatropha’s genotypes derived from 15 combination treatments of plasmid DNA concentration and application time, also wild type was subjected to histochemical and molecular analyses. Based on those analyses, the efficiency of transformation via pollen-tube pathway of three jatropha genotypes ranged from 1.5-16.7%. PCR analysis showed that a number of positive plants were identified by using specific primers hptII and gus, i.e. 1-3 and 3-7 plants of the 15 combined treatments, respectively. It indicated that the transformation efficiency via the pollen-tube pathway varied in each jatropha genotype.<br /><br />Keywords: Jatropha curcas L., pCAMBIA1301, plasmid DNA, stigma-drip<br /><br />

Cell suspension cultures of Jatropha curcas were established and optimized in shake flasks. The stem segments of Jatropha curcas were taken as the explants for studying the techniques of callus induction and cell suspension cultures. The result shows that the optimal medium for callus induction is MS+2,4-D0.6mg/L+ BA1.0mg/L + Sucrose 30g/L, in which the callus is humid, loose and colorful. The fine suspension cell system have been established by inoculating the callus in the medium of MS+NAA0.2mg/L+2,4-D1.0mg/L+BA0.5mg/L for 13 days of cultivation, and the rotation speed should be lower than 120rpm in the culture of oscillation. QD-labeled chitosan-DNA complexes as nano transgenic system, using CdSe as bio-labels and chitosan-DNA(CS-DNA) as nano-scale genic carriers, were prepared and shown to have uniform particle sizes and superior fluorescence properties. Confocal laser scanning microscopy(CLSM) confirmed the target DNA from QD-labeled chitosan-DNA complexes was integrated into the plant cell and suggest the possibility of stable transformation in Jatropha curcas.

Fever is a condition when the body temperature increases to more than 380C. Fever indicates the presence of a disease or other condition in the body. Fever generally occurs as a reaction of the immune system to fight viral, bacterial, fungal, or parasitic infections that cause disease. Some of the diseases that often cause fever are flu, sore throat, and urinary tract infections. Fever can happen to anyone, starting frombaby, children, to adults. This disease can be cured by using drugs that contain antipyretics, analgesics and anti-inflammatory. Jatropha leaves contain active compounds in the form of flavonoids which contain antipyretics, analgesics, and anti-inflammatory properties. Here will be explained about the content of jatropha leaves which can be used as a medicine for fever.
