S1 Figure. Representative mass spectra of putative flavanones and C-methyl flavanones detected in gland extracts of E. meulleriana S1 Fig. Multiple flavanones and C-methyl flavanones detected in gland extracts of E. meulleriana at m/z [M+H] + 271, 285 and 299 using ESI-LCMS/MS in positive mode. All compounds show the characteristic loss of 104 Da of flavanones.

Many (dietary) bitter compounds, e.g. flavonoids, activate bitter receptor hTAS2R39 in cell-based assays. Several flavonoids, amongst which some flavanones, are known not to activate this receptor. As certain flavanones are known to mask bitter taste sensorially, flavanones might act as bitter receptor antagonists. Fourteen flavanones were investigated for their potential to reduce activation o...

Flavanones constitute the majority of flavonoids in citrus fruits such as sweet (Citrus sinensis) and sour oranges (C. aurantium) and their near relatives—tangerines/mandarins (C. reticulata), tangors and tangelos. The relevant chemical analytic literature was searched, abstracted, documented, standardized, examined for quality, enumerated, and summarized in a database for these citrus flavanon...

background: deoxynivalenol (don) is a mycotoxin produced mainly by fusarium graminearum in grains such as wheat and maize. the aim of this study was to evaluate the inhibitory effects of citrus flavanones including, naringin (nar), hesperidin (hes), and neohesperidin (neo) on deoxynivalenol production using response surface methodology (rsm). methods: the studied flavanones were extracted from ...

BACKGROUND/OBJECTIVES This study was aimed at examining the association between dietary flavanones intake and lipid profiles according to the presence of metabolic syndrome (MetS) in Korean women with type 2 diabetes mellitus (T2DM). SUBJECTS/METHODS A cross-sectional analysis was performed among 502 female T2DM patients (non-MetS group; n = 129, MetS group; n = 373) who were recruited from t...

The use of N-methylimidazole as an efficient catalyst for the cyclization of 2′-hydroxychalcones to the corresponding flavanones in DMSO was investigated. The scope of this process was studied and various flavanones were obtained exclusively in good yields.

Abstract Flavanones have been prepared by the cyclization of 2'‐hydroxychalcones using acidic reagents, such as H 2 SO 4 , HX, CF 3 COOH, CH H, KF‐celite, or SiO . Treatment with bases, LiOH, KOH, NaOAc, K CO pyridine, Et N, N ‐methylimidazole afforded flavanones. The conversion to flavanones has conducted Co(salpr), Fe(CN) 6 CuO, Ni(Tfacac) Thioflavanones deprotecting and cyclizing S ‐protecte...

In order to develop a database for flavanones, the dominant flavonoid class in the genus citrus, the relevant scientific literature on flavonoids in grapefruit, lemons, and limes was searched, abstracted, documented, standardized by taxons and units (mg/100 g) and examined for quality. Values for eight flavanones (didymin, eriocitrin, hesperidin, naringin, narirutin, neoeriocitrin, neohesperidi...
