Pegagan (Centella asiatica (L.) Urban) is a herbal plant that contain secondary metabolite compounds like phenol and flavonoid. NaCl salinity one of abiotic stress enhanced synthesis some metabolites in plants. This study was investigated the effect to phenolic compound, total flavonoid antioxidant activity pegagan leaves. were treated with five different concentrations, 0 mM (1), 50 (2), 100 (...

abstract: mustard is a natural multi-functional additive with strong hot flavor. in this research, powdered yellow mustard (sinapis alba) was heated by 21 different thermal processes, statistically designed by response surface methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

Phenolic acid derivatives are typical constituents of Clerodendranthus spicatus which were considered to the active principles of this medicinal plant. These chemical constituents with their interesting frameworks and biological significance attracted our attention. As part of our ongoing chemical investigation of C. spicatus using various column chromatography techniques, a new phenolic compou...

In the mol-ecule of the title compound, [Ni(C19H20N2O4)(H2O)2], the central Ni(II) ion lies on a mirror plane and is surrounded by an N2O4 coordination set in the form of a distorted octa-hedron defined by the O atoms of two water mol-ecules and by two phenolic O and two imine N atoms of the tetra-dentate Schiff base ligand. In the crystal, O-H⋯O hydrogen bonds between the water mol-ecules and ...

In their comprehensive work on 2acetylaminofluorenel (Fig. 1) the Weisburgers and Morris (l-4) have identified six phenolic metabolites of this carcinogen in the urine of adult rats. During recent studies (5) on this compound we have encountered a new acidic urinary metabolite. This metabolite is of interest since its excretion is greatly reduced by administration of a-methylcholanthrene, a pot...

A rapid, sensitive and selective analysis method using Ultra High Performance Liquid Chromatography coupled to triple-quadrupole Mass Spectrometry (UHPLC-QqQ-MS) has been developed for the quantification of polyphenols in rosé wines. The compound detection being based on specific MS transitions in Multiple Reaction Monitoring (MRM) mode, the present method allows the selective quantification of...

Dobriner, Rhoads, and Lavin (8, 9) isolated from the excreta of rats injected subcutaneously with 1,2,5,6_dibenzanthracene 1 a phenolic compound which was later shown by Cason and Fieser (3) to have an absorption spectrum identical with that of synthetic 4',8'-dihydroxy-i,2,5,6-dibenzanthracene (Fig. z); the same phenolic derivative was also present in the excreta of mice which had received sim...

In the title compound, C14H15BrN2O2S, synthesized by the reaction of the corresponding phenacyl thio-cyanate with morpholine, the dihedral angle between the 1,3-thia-zole ring and the phenolic substituent ring is 23.46 (10)° as a result of the steric influence of the ortho-methyl group on the thia-zole ring. A strong intra-molecular phenolic O-H⋯N hydrogen bond is present in the mol-ecule. In t...

Honokiol is a poly-phenolic compound that exerts neuroprotective properties through a variety of mechanisms. It has therapeutic potential in anxiety, pain, cerebrovascular injury, epilepsy, and cognitive disorders including Alzheimer's disease. It has been traditionally used in medical practices throughout much of Southeast Asia, but has now become more widely studied due to its pleiotropic eff...

Four phenolic compounds were isolated from the roots of Sanguisorba officinalis L. by silica gel column chromatography and preparative HPLC. On the basis of chemical and spectroscopic methods, their structures were identified as methyl 4-O-β-D-glucopyranosy-5-hydroxy-3-methoxylbenzoate (1), 3,3′,4′-tri-O-methylellagic acid (2), fisetinidol-(4α-8)-catechin (3), and (+)-catechin (4). Compound 1 i...
