8‐Hydroxyflavone is not found in nature. While the 13C chemical shifts of 8‐hydroxyflavone have been reported previously, the observed 13C chemical shifts were not assigned. A previously reported empirical predictive tool has been applied in reverse in order to deconvolute the 13C chemical shifts for 8‐hydroxyflavone from each of those of 7,8,4′‐trihydroxyflavone and 7,8‐dihydroxyflavone together with those of 7‐hydroxyflavone, 4′‐hydroxyflavone, and flavone. The two sets of calculated 13C…

Correlation between 13C NMR chemical shifts and complete sets of descriptors of natural coumarin derivatives
Abstract Choosing the best set of descriptors for quantitative structure-property relationship (QSPR) is subjective and different descriptor set may be obtained for the same case. A complete set of
The effect of 7,8,4´-trihydroxyflavone on tyrosinase activity and conformation: Spectroscopy and docking studies.
7,8,4´-trihydroxyflavone was found to strongly inhibit the oxidation of l-DOPA by tyrosinase with an IC50 value of 10.31 ± 0.41 μM and the inhibitory mechanism was determined to be reversible and non-competitive.
Selective and efficient oxidative modifications of flavonoids with 2-iodoxybenzoic acid (IBX)
Abstract 2-Iodoxybenzoic acid (IBX), a mild and efficient hypervalent iodine oxidant, has been utilised in different reaction conditions to perform several efficient oxidative modifications of
Analysis of flavonoids: tandem mass spectrometry, computational methods, and NMR.
The application of NMR data to the mass spectrometric examination of flavonoids is discussed and the addition of a chromophoric ligand to allow the application of infrared (IR) multiphoton dissociation as an alternative to collision-induced dissociation (CID) for the differentiation of isomers.
Novel Techniques Towards the Identification of Different Classes of Polyphenols
Polyphenols are secondary metabolites ubiquitously distributed among all higher plants, which affect the organoleptic and nutraceutical properties of fruits, vegetables and other plants. They have


A predictive tool for assessing 13C NMR chemical shifts of flavonoids
A simple predictive tool for assigning flavonoid 13Cchemical shifts, which is based on the cumulative differences between the monohydroxyflavones and flavone 13C chemical shifts, is demonstrated and is expected to be useful for rapid assessment of flavonoidal 13C NMR spectra and for assigning substitution patterns in newly isolated flavonoids.
1H and 13C‐NMR data of hydroxyflavone derivatives
In the present study, the complete 1H and 13C NMR spectral assignments were presented for 6 hydroxyFlavones, and NMR data of additional 14 hydroxyflavone derivatives were compared with those of the 6 hydroXYflavones.
A combined nuclear magnetic resonance and computational study of monohydroxyflavones applied to product ion mass spectra.
The magnitude of gamma, which is dependent on the relative bond orders within the C-ring of the protonated and deprotonated molecules of monohydroxyflavones, can be rationalized on the basis of the magnitudes of the 13C- and 1H-chemical shifts as determined by nuclear magnetic resonance spectroscopy.
Synthesis and biological evaluation of substituted flavones as gastroprotective agents.
Flavone (1) was found to protect against ethanol-induced gastric damage in rats; however, it is known that certain compounds in the flavone class, including flavone itself, are inducers of hepatic
