“…Moreover, several flavanones (dihydroflavones) were also characterized for first time in V. faba : eriodictyol‐di‐ C ‐dihexoside ( 60 ) , naringenin 6,8‐di‐ C ‐hexoside ( 88 ) , naringenin 6‐ C ‐α‐ d ‐glucoside (hemipholin; 101 ) , naringenin 7‐ O ‐glucoside (prunin; 131 ) , and pinocembrin ( 144 ) . Compounds 60 , 84 , 88 , 91 , 101 , and 110 gave a fragmentation pattern typical of C ‐glycosides, as commented above.…”

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.

“…The methanol extract (6.5 g) yielded taxifolin ( 1 ) [ 8 ], astragalin ( 2 ) [ 9 ], isorhamnetin 3- O -β- d -glucoside ( 3 ) [ 10 ], (−)-catechin ( 4 ) [ 11 ], benzoate glucoside ( 5 ) [ 12 ], benzyl-β- d -glucoside ( 6 ) [ 13 ], benzyl-β- d -rutinoside ( 7 ) [ 14 ], 2-methoxy-phenyl-β- d -glucoside ( 8 ) [ 15 ], 3,4-dimethoxyphenyl-β- d -glucoside ( 9 ) [ 16 ], raspberry ketone ( 10 ) [ 17 ], p-anisic acid ( 11 ) [ 18 ], 4-hydroxybenzoic acid 4- O -β- d -glucoside ( 12 ) [ 19 ], p-coumaric acid ( 13 , 6.0 mg) and its glucoside ( 14 ) [ 20 , 21 ], trans -vaginoside ( 15 ) [ 22 ] and abscisic alcohol glucoside ( 16 ) [ 23 ]. The methanol:water (5:1) extract afforded kaempferol-3- O -β-rutinoside ( 17 ) [ 24 ], kaempferide-3- O -β-rutinoside ( 18 ) [ 25 ], tiliroside ( 19 ) [ 26 ], and syringetin 3- O -β- d -glucoside ( 20 ) [ 27 ] ( Figure 1 ).…”

The phytochemical analysis of the polar extracts of Cedrus brevifolia needles yielded 20 compounds, namely from the methanol extract we isolated three flavonoids (1–3), one hydrolysable tannin (4), eleven phenolic derivatives (5–15) and one apocarotenoid (16), while from the methanol: water (5:1) extract we isolated four flavonoids (17–20). Chemical structures of all isolated compounds were determined by 1D, 2D-NMR (1 Dimension, 2 Dimensions Nuclear Magnetic Resonance) and UV-Vis (Ultraviolet-Visible) spectroscopy. Furthermore, the antioxidant potentials and the anti-inflammatory activities of both crude extracts and isolates were evaluated through DPPH radical scavenging capability, linoleic acid lipid peroxidation inhibition, and soybean LOX inhibition assays. This is the first report on the chemical profile of C. brevifolia needles. Catechin was the main compound derived from the methanol extract. According to our results, 4-O-β-d-glucopyranyl trans-p-coumaric acid and taxifolin were the most active ingredients.

“…Compound 2 was identified as quercitrin, a 3-O-rhamnosylquercetin, by comparison of its 1 H NMR spectral data with those found in the literature (Pyo et al, 2002). Compound 3 was identified as 6-C-glycosylnaringenin through comparison of its spectral data with those reported 1 H and 13 C NMR spectral data in literature (Budzianowski and Skrzypczakowa, 1978;Abdel-Kader, 1997). Compound 4 was an impure catechin derivative and due to the weak inhibitory activity further efforts for the structure elucidation were not applied.…”
