OBJECTIVES The susceptibility of Candida albicans to catechin under varying pH conditions and the synergism of the combination of catechin and antimycotics were evaluated. METHOD Antifungal activity was determined by broth dilution and calculation of cfu. RESULTS The antifungal activity of catechin was pH dependent. The concentration of epigallocatechin gallate (EGCg) causing 90% growth inh...

PURPOSE Preclinical studies suggested that green tea or green tea catechins can modulate the activities of drug-metabolizing enzymes. We conducted this clinical study to determine the effect of repeated green tea catechin administration on human cytochrome P450 (CYP) enzyme activities. METHODS Forty-two healthy volunteers underwent a 4-week washout period by refraining from tea or tea-related...

Effects of some polyphenols and their related compounds (chlorogenic acid, caffeic acid, quinic acid, ferulic acid, gallic acid, D-(+)-catechin, D-(-)-catechin, 4-hydroxy-3-methoxybenzoic acid, salicylic acid, L-dopa, dopamine, L-adrenaline, L-noradrenaline, o-dihydroxybenzene, m-dihydroxybenzene, and p-dihydroxybenzene) on the formation of 13-hydroperoxide octadecadienoic (13-HPODE) acid-deriv...

The aim of this study is synthesis molecularly imprinted polymers (MIPs) and evaluation for extraction catechin. Catechin a bioactive compound which found abundantly in green tea. In paper, MIPs was synthesized by precipitation polymerization technique catechin, acrylic acid trimethylolpropane trimethacrylate as template, functional monomer cross-linker molecular ratio (1:12:12), respectively. ...

Cocoa and chocolate products have been delicacies for hundreds of years. Only recently have they been recognized as significant sources of phytochemicals with healthful effects. These foods are among the most concentrated sources of the procyanidin flavonoids, catechin and epicatechin. Recent studies have shown that these polyphenols are absorbed from the intestine of animals and humans with ep...

During the last two decades, new drug delivery strategies have been invented that able to solve microbial resistance against antibiotics. The goal of current report was assess antimicrobial effects nano-catechin gels clinically isolated Porphyromonas gingivalis, one main causes periodontal disease. Catechin-loaded chitosan nanoparticles were prepared by adding a catechin solution solution. Then...
