“…Only one hybrid clone (viz., CJH 12 (203.36)) recorded significantly higher saponification values compared to the control variety TNMC 7 (201.12). Similar studies on the saponification value of J. curcas hybrids have been reported by Ntaganda (2014) .…”

Jatropha curcas is a tropical species that has been recognized as a promising biodiesel plant. During 2018–2021, researchers at Forest College and Research Institute, Mettupalayam, elicited information on Jatropha’s biochemical characteristics, growth performance, variability, and association studies for biometric variables using five backcross (BC4F1) hybrid clones of Jatropha with a control variety TNMC 7. In terms of seed yield, two hybrid clones, CJH 13 (1,218.60 g) and CJH 12 (1,034.40 g), outperformed the other hybrid clones. The seed oil content was higher in CJH 5 (34.19%). The seed oil content had moderate PCV (16.49%) and GCV (16.39%) values, as well as high heritability (99%) and genetic advance (33.56%) as a percentage of the mean. The number of fruits per bunch (0.845 and 0.850) and the number of bunches per branch (0.771 and 0.788) had significant positive phenotypic and genotypic correlations with seed yield, respectively. The iodine numbers, cetane numbers, and saponification values of all hybrid clones were acceptable and satisfactory and were in good compliance with Indian and international biodiesel standards.

“…The physical and chemical properties of Jatropha biodiesel are presented in Table 4. The properties of Jatropha biodiesel [58][59][60] are similar to that of diesel [61], with the advantages of low viscosity, high flash point, and high cetane number. Biodiesel produced from Jatropha oil meets American Society of Testing Materials (ASTM) [59] biodiesel standard and can be used directly in the engine to replace petroleum diesel [62,63].…”

In this study, a Life Cycle Cost (LCC) is integrated within a life cycle assessment (LCA) model to comprehensively evaluate the energy, environment, and economic impacts of the Jatropha biodiesel production in China. The total energy consumption of producing 1 ton of Jatropha biodiesel is 17566.16 MJ, in which fertilizer utilization and methanol production consume 78.14% and 18.65% of the overall energy consumption, respectively. The production of 1 ton of Jatropha biodiesel emits a number of pollutants, including 1184.52 kg of CO2, 5.86 kg of dust, 5.59 kg of NOx, 2.67 kg of SO2, 2.38 kg of CH4, and 1.05 kg of CO. By calculating and comparing their environmental impacts potentials, it was discovered that NOx and dust emissions during the fertilizer application, combustion of Jatropha shells, and methanol production urgently require improvement, as they contribute to serious global warming and particulate matter formation issues. LCC study shows that the cost of Jatropha biodiesel is 796.32 USD/ton, which is mostly contributed by Jatropha oil cost (44.37% of the total cost) and human input (26.70% of the total cost). Additional profits are generated by the combustion of Jatropha shells and glycerol by-product, which can compensate 16.76% of the cost of Jatropha biodiesel. Graphical Abstract

Abstract:To investigate the potential use of Jatropha curcas L. seed oil, dried Jatropha curcas L. seeds were crushed to release the kernels and oil was extracted using Soxhlet apparatus and the physicochemical characteristics of the oil determined using standard methods. The physico-chemical characteristics showed: oil yield 42.19%, specific gravity 0.93, saponification value 122.49mgKOH/g, iodine value 129.66gI 2 /100g, acid value 1.38mgKOH/g, free fatty acid value 0.74mgKOH/g and peroxide value 1.55meq/Kg. The phytochemical screening of the oil showed the presence of saponins, alkaloids, steroids, terpenoids and cardiac glycosides, while tannins, flavonoids and phenols were absent. From the determined parameters, Jatropha curcas seed oil may be use as cooking oil and in cosmetics. In addition, the revealed phytochemical suggested that the seeds oil has pharmacological potentialities.
