“…Similar results were obtained in this work, even with different method of extraction. Nevertheless, these results are different of that obtained by Martínez-Herrera, Chel-Guerrero & Martínez-Ayala (2004), because they reported 96% of PEs extraction through hydroalcoholic extraction, quantified by HPLC; while, in this work the intensity of the spots was higher on Soxhletmethanol extracts than hydroalcoholic extraction (Fig. S1).…”

“…In Mexico, Brazil and India, non-toxic varieties of this species have been identified with very low or non-detectable levels of phorbol esters (PEs) in seeds (Laviola et al, 2010;Martínez-Herrera, Chel-Guerrero & Martínez-Ayala, 2004;Kumar, Anand & Reddy, 2011). PEs are known as Jatropha factors because each one of them has the same nucleus diterpene moiety, namely, 12-deoxy-16-hydroxy-phorbol (DHP) which is coupled to unstables intramolecular diterpenes (named C 1 -C 6 factors) (Hirota et al, 2017).…”

Jatropha curcas L. belongs to Euphorbiaceae family, and it synthesizes flavonoid and diterpene compounds that have showed antioxidant, anti-inflammatory, anticancer, antiviral, antimicrobial, antifungal and insecticide activity. Seeds of this plant accumulate phorbol esters, which are tigliane type diterpenes, reported as toxic and, depending on its concentration, toxic and non-toxic varieties has been identified. The aim of this work was to characterize the chemical profile of the extracts from seeds, leaves and callus of both varieties (toxic and non-toxic) of Jatropha curcas, to verify the presence of important compounds in dedifferentiated cells and consider the possibility of using these cultures for the massive production of metabolites. Callus induction was obtained using NAA (1.5 mg L−1) and BAP (1.5 mg L−1) after 21 d for both varieties. Thin layer chromatography analysis showed differences in compounds accumulation in callus from non-toxic variety throughout the time of culture, diterpenes showed an increase along the time, in contrast with flavonoids which decreased. Based on the results obtained through microQTOF-QII spectrometer it is suggested a higher accumulation of phorbol esters, derived from 12-deoxy-16-hydroxy-phorbol (m/z 365 [M+H]+), in callus of 38 d than those of 14 d culture, from both varieties. Unlike flavonoids accumulation, the MS chromatograms analysis allowed to suggest lower accumulation of flavonoids as the culture time progresses, in callus from both varieties. The presence of six glycosylated flavonoids is also suggested in leaf and callus extracts derived from both varieties (toxic and non-toxic), including: apigenin 6-C-α-L-arabinopyranosyl-8-C-β-D-xylopyranoside (m/z 535 [M+H]+), apigenin 4′-O-rhamnoside (m/z 417 [M+H]+), vitexin (m/z 433 [M+H]+), vitexin 4′-O-glucoside-2″-O-rhamnoside (m/z 741 [M+H]+), vicenin-2 (m/z 595 [M+H]+), and vicenin-2,6″-O-glucoside (m/z 757 [M+H]+).

Legume lipoxygenase: Strategies for application in food industry

et al. 2020

Lipoxygenase (LOX) is a widely distributed enzyme in plant and animal cells. It catalyzes the oxidation of polyunsaturated fatty acid into fatty acid hydroperoxides. LOX is also associated with the production of aroma substrates, color changes, and alternation of physico‐chemical characteristics. The associated reaction could be either desirable or undesirable in food production. An understanding of LOX characteristics and functional principles is essential for utilizing LOX as a natural food ingredient. Legumes are nutrient‐dense food ingredient and also serve as a good source of LOX. This paper is focused on the biological function of LOX in legumes, the history of legume LOX, the application of legume LOX in the food industry, and the inhibition strategies of unwanted LOX‐catalyzed reaction.
