Valente IM, Cabrita ARJ, Malushi N, Oliveira HM, Papa L, Rodrigues JA, Fonseca AJM, Maia MRG. Unravelling the phytonutrients and antioxidant properties of European Vicia faba L. seeds. Food Res Int 2018; 116:888-896. [PMID: 30717020 DOI: 10.1016/j.foodres.2018.09.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2018] [Revised: 08/27/2018] [Accepted: 09/08/2018] [Indexed: 12/30/2022]
Abstract
For the first time, seven European varieties of Vicia faba L. seeds were investigated for (1) their phytonutrients profile by HPLC-DAD-MS/MS, (2) total phenolic content (TPC), and (3) antioxidant capacity (DPPH and FRAP assays). A wide range of compounds were identified, namely alkaloids, organic acids, terpenoids, jasmonates, and phenolics; these two latter being the most abundant. TPC ranged between 2.62 and 4.3 mg (gallic acid equivalent) g-1 dry weight, for V. faba major variety Belshi and V. faba minor variety Bauska, respectively. The DPPH radical scavenging capacity showed poor correlation (r = 0.550, P = .041) with TPC, suggesting the presence of other antioxidant sources than phenolics. Still, FRAP was positively correlated with TPC (r = 0.709, P < .01) and DPPH (r = 0.819, P < .01). These results elucidated the phytonutrients and antioxidant properties of V. faba L. seeds as functional food sources.

Abu-Reidah IM, del Mar Contreras M, Arráez-Román D, Fernández-Gutiérrez A, Segura-Carretero A. UHPLC-ESI-QTOF-MS-based metabolic profiling of Vicia faba L. (Fabaceae) seeds as a key strategy for characterization in foodomics. Electrophoresis 2015; 35:1571-81. [PMID: 24658881 DOI: 10.1002/elps.201300646] [Citation(s) in RCA: 62] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2013] [Revised: 02/18/2014] [Accepted: 03/10/2014] [Indexed: 11/08/2022]
Abstract
Vicia faba (Fabaceae) is a popular food in many countries and a good source of nutrients. However, little is known about its phytochemical composition, specially referring to phenolic compounds. In the present work, the dietary metabolites from a hydro-methanolic extract of V. faba seeds were thoroughly characterized by a nontargeted analytical approach based on reversed-phase ultra-HPLC (UHPLC) coupled to QTOF-MS. A total of 155 primary and secondary metabolites of various structural types were characterized: carbohydrates, amino acids, organic acids, alkaloids, terpenoids, jasmonates, and, mainly, polyphenols. Among the latter group, 73 compounds were characterized for the first time in this legume. In addition, 24 new structures, belonging to jasmonates and glycosylated N-containing compounds, were also proposed. Thus, this methodology could be implemented in foodomics as a characterization strategy to complement the knowledge of the phytochemical composition of vegetables.

Abstract
Western white pine (Pinus monticola) seeds exhibit deep dormancy at maturity and seed populations require several months of moist chilling to reach their uppermost germination capacities. Abscisic acid (ABA) and its metabolites, phaseic acid (PA), dihydrophaseic acid (DPA), 7'-hydroxy ABA (7'OH ABA) and ABA-glucose ester (ABA-GE), were quantified in western white pine seeds during dormancy breakage (moist chilling) and germination using an HPLC-tandem mass spectrometry method with multiple reaction monitoring and internal standards incorporating deuterium-labeled analogs. In the seed coat, ABA and metabolite levels were high in dry seeds, but declined precipitously during the pre-moist-chilling water soak to relatively low levels thereafter. In the embryo and megagametophyte, ABA levels decreased significantly during moist chilling, coincident with an increase in the germination capacity of seeds. ABA catabolism occurred via several routes, depending on the stage and the seed tissue. Moist chilling of seeds led to increases in PA and DPA levels in both the embryo and megagametophyte. Within the embryo, 7'OH ABA and ABA-GE also accumulated during moist chilling; however, 7'OH ABA peaked early in germination. Changes in ABA flux, i.e. shifts in the ratio between biosynthesis and catabolism, occurred at three distinct stages during the transition from dormant seed to seedling. During moist chilling, the relative rate of ABA catabolism exceeded ABA biosynthesis. This trend became even more pronounced during germination, and germination was also accompanied by a decrease in the ABA catabolites DPA and PA, presumably as a result of their further metabolism and/or leaching/transport. The transition from germination to post-germinative growth was accompanied by a shift toward ABA biosynthesis. Dormant imbibed seeds, kept in warm moist conditions for 30 days (after an initial 13 days of soaking), maintained high ABA levels, while the amounts of PA, 7'OH ABA, and DPA decreased or remained at steady-state levels. Thus, in the absence of conditions required to break dormancy there were no net changes in ABA biosynthesis and catabolism.

Abstract
Metabolism of R,S-[2-(14)C]abscisic acid (ABA) was studied in detached leaves of six wheat (Triticum aestivum) cultivars, using non-stressed leaves or leaves water stressed by desiccation to 90% of their original fresh weight. The rate constant of ABA metabolism was similar in nonstressed leaves of all cultivars. Water stress resulted in significantly lower rate constants in two cultivars which accumulated high levels of ABA when stressed, the constants decreasing by a factor of about 1.5. Rate constants for the remainder of the cultivars were not significantly different from those for the non-stressed controls. It was calculated that if decreased metabolism was the mechanism for the accumulation of ABA following water stress the rate constants of metabolism would have to be reduced by a factor of between 25 and 70. The results therefore support the hypothesis that enhanced synthesis rather than reduced degradation is the main process by which ABA levels are elevated following experimentally induced water stress. There were differences between the six cultivars in the products of ABA metabolism. Over the time period studied, oxidation to phaseic acid and dihydrophaseic acid as well as to other unidentified metabolites appeared to be the predominant pathway of ABA metabolism, rather than conjugation to ABA glucose ester and other more polar compounds.
