“…Unlike other species of the genus Jatropha, the quality of the oil extracted from the seed of Jatropha mollissima is still little reported in the literature, especially in relation to the composition of fatty acids. According to Barros et al, (2015) [11], the mean oil content of Pinhão-Bravo is 18.3% w/w, with a higher content of unsaturated than saturated fatty acids. Indeed, Linoleic (C18:2) and oleic (C18:1) acids represent around 58-63 % and 17-19% of total fatty acids.…”

Caatinga is a Brazilian semi-arid ecosystem that stands out for presenting unique environmental characteristics with a dry, spiny and deciduous shrub/forest vegetation with several species that can be renewable oil sources with potential applicability in oleochemical and nutrition. Caatinga oilseeds have a high content of unsaturated fatty acids, phytosterols and sterols, and this composition is related to its nutritional potential. The present review summarizes the knowledge on the oil contents and fatty acid profiles of seeds from six representatives caatinga species. It was observed that plants species like Caju (Anacardium occidentale L.), Favela (Cnidoscolus quercifolius Pohl), Licuri (Syagrus coronata (Mart.) Becc.), Pinhão-bravo (Jatropha mollissima Pohl Baill), Pequi (Caryocar brasiliense Camb) and Oiticica (Licania rígida Benth) contains approximately 33.1, 33.5, 49.2, 18.3, 70.16 and 57.0 % w/w of oil, respectively, on a dry weight basis. Their fatty acid profiles are mostly saturated for Licuri oil, with a high content of lauric acid (up to 40%) and unsaturated for Favela, Pinhão-bravo, Cashew nut, Pequi and Oiticica oils. Oiticica oil shows a high concentration of unusual conjugated polyunsaturated fatty acids, like α-Eleostearic and Licanic acid with 16.90 and 43.20 % w/w, respectively.

“…[17] Overall, jatropha, a perennial shrub with inedible seeds containing toxic compounds, has emerged as a promising alternative for biodiesel production due to its ease of cultivation as an alternative to traditional crops. [18] The field of biodiesel production has garnered significant research attention, particularly in the use of heterogeneous catalysts. Basumatary et al investigated the use of calcium-rich waste shells to develop sustainable and cost-effective CaObased catalysts for biodiesel synthesis via esterification or transesterification pathways.…”

The rationale for this study lies in the investigation of the transesterification of crude Jatropha curcas oil into biodiesel using advanced heterogeneous catalysts under supercritical methanol conditions. The oxides of strontium, lanthanum, and zinc (SrO, La2O3, and ZnO) were synthesized with varying loadings (2 wt %, 6 wt %, and 10 wt %) on γ‐Al2O3 using the wet impregnation method followed by calcination at 900 °C. To gain a comprehensive understanding of the prepared catalysts, multiple analytical techniques were employed, including scanning electron microscopy (SEM) with energy‐dispersive X‐ray spectroscopy (EDS), Brunauer‐Emmett‐Teller (BET) surface area analysis, X‐ray diffraction (XRD), and Fourier transform infrared (FT‐IR) spectroscopy. The performance of the catalysts was assessed through the measurement of biodiesel yield, where the SrO/γ‐Al2O3, ZnO/γ‐Al2O3, and La2O3/γ‐Al2O3 systems produced yields of 97.54 %, 97.49 %, and 97.36 %, respectively, under identical reaction conditions of a 1 : 40 oil to methanol molar ratio, 10 wt % catalyst loading amount, 300 °C reaction temperature, 90 bar reaction pressure, and a reaction time of 3 min. Despite a minimal decrease of 0.05 %, zinc oxide catalysts remain highly attractive due to their favorable price position compared to strontium. Additionally, the catalyst can be reused up to 12 times with minimal loss in biodiesel yield (~2 %).

“…The focus on renewable energies has identified Jatropha curcas L. as a promising plant to contribute to a more sustainable alternative. This is due to the yield and quality of the oil extracted from the seeds, having a relatively high oil content, ranging from ~30% to ~35% (Barros et al, 2015;de Oliveira et al, 2009). *Corresponding author.…”

Developing a protocol for somatic embryogenesis (SE) for adult mother plants of Jatropha curcas, aids to overcome problems such as harvesting time and an uneven yield, providing the opportunity to propagate proven elite genotypes. Until now, several authors have achieved SE in J. curcas using different explants, however, in none of these protocols adult plants have been used as mother plant material. Furthermore, the challenge of overcoming the morphogenesis limitations successfully and further regeneration of adult plants of J. curcas has been great. The main objective of this study was to develop a somatic embryogenesis protocol for adult plants of the oil producing J. curcas. transverse thin cell layers (tTCL) of young petioles were used as explants. Half strength Y3 and MS media were used containing three different concentrations of 2,4-dichloropherioxyacetic acid and 6-benzilaminopurine in a factorial trial. Nine accessions of J. curcas of various ages (3-12 years.) were tested using this protocol. All accessions responded positively to callus induction and to the induction of somatic embryos, demonstrating the protocol to be genotype-independent. This study enables micropropagation of adult of proven elite plants of J. curcas via somatic embryogenesis.
