Photoluminescence quantitative analysis of Gallic acid and Caffeine in green tea using multi-way chemometric approaches
Green tea is considered as a dietary source of antioxidant nutrients, which acts upon human health. Green tea leaves contain three main components in the form of simple hydroxy benzoic acids such as gallic acid, propyl gallate and xanthic bases (caffeine), have been reported to prevent or delay a number of degenerative diseases and act mainly upon the central nervous system and stimulating wake...

متن کاملGallic 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 کاملP-20: Role of Green Tea in Increasing Fertility
Background: Green tea is a popular type of tea that is made of unfermented tea leaves. Green tea has been used for thousands of years by people in Eastern countries for a variety of health reasons. One of the primary benefits of Green Tea in regard to fertility is not in what it contains, but rather in what it does not contain. Materials and Methods: In the present study attempts to investigate...
