Gallic acid
Anhydrous 3,4,5-trihy-droxy-benzoic acid, C(7)H(6)O(5), is essentially planar, with its non-H atoms exhibiting mean and maximum deviations from coplanarity of 0.014 and 0.0377 (5) Å, respectively. The C-C-C-OH torsion angle about the bond linking the carboxyl group to the benzene ring is -0.33 (10)°. In the crystal, the -COOH groups form centrosymmetric hydrogen-bonded cyclic dimers [graph set ...
متن کاملGallic acid pyridine monosolvate
IN THE TITLE COMPOUND (SYSTENATIC NAME: 3,4,5-trihy-droxy-benzoic acid pyridine monosolvate), C(5)H(5)N·C(7)H(6)O(5), the gallic acid mol-ecule is essentially planar (r.m.s deviation = 0.0766 Å for non-H atoms) and is linked to the pyridine mol-ecule by an O-H⋯N hydrogen bond. An intra-molecular O-H⋯O hydrogen bond occurs in the gallic acid mol-ecule. The gallic acid and pyridine mean planes ma...
متن کاملQuantification of Gallic Acid in Fruits of Three Medicinal Plants
Triphala is a traditional herbal formulation consisting of dried fruits originating from three medicinal plants, namely Terminalia chebula, Terminalia bellirica and Phyllanthus embelica. It is used in folk medicine for the treatment of headaches, dyspepsia and leucorrhoea. There are some reports regarding Triphala"s pharmacological effects including its anti-cancer, radioprotective, hypocholest...
متن کاملDifferent generation of inhibitors against gallic acid-induced apoptosis produces different sensitivity to gallic acid.
Gallic acid (3,4,5-trihydroxybenzoic acid), a naturally occurring plant phenol, showed selective cytotoxicity against tumor cells with higher sensitivity than normal cells such as hepatocytes and keratinocytes. To elucidate the difference in sensitivity between normal and tumor cells to gallic acid, we studied whether the inhibitor of gallic acid-induced apoptosis existed or not. A serum-free c...
متن کاملFree radicals produced by the oxidation of gallic acid: An electron paramagnetic resonance study
BACKGROUND Gallic acid (3,4,5-trihydroxybenzoic acid) is found in a wide variety of plants; it is extensively used in tanning, ink dyes, as well as in the manufacturing of paper. The gallate moiety is a key component of many functional phytochemicals. In this work electron paramagnetic spectroscopy (EPR) was used to detect the free radicals generated by the air-oxidation of gallic acid. RESUL...
