The physic nut shrub, Jatropha curcas (Euphorbiaceae), has been considered as a “miracle tree”, particularly as a source of alternate fuel. Various extracts of the plant have been reported to have insecticidal/acaricidal or molluscicidal/anthelminthic activities on vectors of medical or veterinary interest or on agricultural or non-agricultural pests. Among those extracts, the phorbol ester fraction from seed oil has been reported as a promising candidate for use as a plant-derived protectant of a variety of crops, from a range of pre-harvest and post-harvest insect pests. However, such extracts have not been widely used, despite the “boom” in the development of the crop in the tropics during recent years, and societal concerns about overuse of systemic chemical pesticides. There are many potential explanations to such a lack of use of Jatropha insecticidal extracts. On the one hand, the application of extracts potentially harmful to human health on stored food grain, might not be relevant. The problem of decomposition of phorbol esters and other compounds toxic to crop pests in the field needing further evaluation before such extracts can be widely used, may also be a partial explanation. High variability of phorbol ester content and hence of insecticidal activity among physic nut cultivars/ecotypes may be another. Phytotoxicity to crops may be further limitation. Apparent obstacles to a wider application of such extracts are the costs and problems involved with registration and legal approval. On the other hand, more studies should be conducted on molluscicidal activity on slugs and land snails which are major pests of crops, particularly in conservation agriculture systems. Further evaluation of toxicity to natural enemies of insect pests and studies on other beneficial insects such as pollinators are also needed.

“…The purified PEs could also be converted or transformed chemically into nontoxic compounds with beneficial activities such as the hydrolysis of 12-deoxy-16-hydroxyphorbol that results in the synthesis of 12-deoxyphorbol-13-phenyl acetate, a compound that is considered as a promising adjuvant for antiviral therapy because of its anti-HIV properties (Wender et al, 2008). Some studies had been reported the antifungal and insecticide properties from Jatropha curcas seed cake attributed to the presence of PE , Devappa et al, 2012Ratnadass and Wink, 2012;Saetae and Suntornsuk, 2010).…”

Jatropha curcas plant shrub of Euphorbiaceae family is a plant whose seeds are rich in oil that can be used for biofuel production. However the seeds contain many toxic compounds which the most important ones are known as phorbol esters (PEs). This study has as aim the study of the technical and economic feasibility of the supercritical fluid to extract the PEs present in the Jatropha seed cake. The effect of temperature (40 -100 ºC) and pressure (100 -500 bar) on the phorbol yield was investigated using a central composite design methodology to determine the significance and interactions of these parameters. PEs in the extracted samples were analyzed and quantified by HPLC. The supercritical fluid extraction was effective in the PE extraction from Jatropha curcas cake varying from 23.0%, at 70 ºC and 500 bar to 2.6% at 90 ºC and 160 bar. The results showed that pressure had the most significant enhancing effect on the phorbol ester yield. Simulations of phorbol ester extraction from Jatropha curcas cake were carried out using SuperPro Designer 9.0 to evaluate the production costs of an industrial process to treat the necessary quantity of cake. It was possible to conclude that the supercritical extraction is a promising technology that can be applied to detoxify the Jatropha curcas cake.

“…They also possess some beneficial effects, because not all of the PEs are toxic and their activity and potency vary from one type of PE to another [11]. Many works have been studied in order to extract the PEs to add value to this by product [12][13][14][15]. The purified PEs could also be converted or transformed chemically into nontoxic compounds with beneficial activities such as the hydrolysis of 12-deoxy-16-hydroxyphorbol that results in the Abstract Jatropha curcas plant shrub of Euphorbiaceae family is a plant whose seeds are rich in oil that can be used for biofuel production.…”
