Anthocyanins are one of the main classes of flavonoids in red wines, and they appear to contribute significantly to the powerful antioxidant properties of the flavonoids. In grapes and wines the anthocyanins are in the flavylium form. However, during digestion they may reach higher pH values, forming the carbinol pseudo-base, quinoidal-base, or the chalcone, and these compounds appear to be abs...

This study shows the effects of spices, and their phenolic and flavonoid compounds, on prostate cell lines (PNT1A, 22RV1 and PC3). The results of an MTT assay on extracts from eight spices revealed the strongest inhibitory effects were from black pepper and caraway seed extracts. The strongest inhibitory effect on prostatic cells was observed after the application of extracts of spices in conce...

Phenolic compounds including flavonoids and phenolic acids are plants secondary metabolites. Due to their ability to act as antioxidant agents, there is a growing interest to use those components in traditional medicine for cancer prevention or treatment. The aim of this study was to measure the amounts of total phenolics and flavonoids as well as anti-proliferative effect of aqueous extract of...

recently, subcritical water extraction (swe) has been well known as a green technology for extraction of bioactive compounds from plants. in this study, subcritical water extraction, ultrasound assisted extraction (uae) and shaker solvent extraction (sse) were compared for extraction of phenolic compounds from fig (ficuscarica) pulp and skin. antioxidant activity of the extracts was evaluated u...

Juniperus drupacea fruit is widely used in traditional and complementary medicine Turkey for the treatment of different diseases various forms such as molasses tar. This study was carried out to evaluate phenolic compounds, organic acid, sugar, macro- micromineral distributions methanol water extracts J. drupace fruit, well their antioxidant antimicrobial potential. For this purpose, total cont...

The trypanocidal action of green tea catechins against two different developmental stages of Trypanosoma cruzi is reported for the first time. This activity was assayed with the nonproliferative bloodstream trypomastigote and with the intracellular replicative amastigote parasite forms. An ethyl acetate fraction from Camellia sinensis green tea leaves, which contains most of the polyphenolic co...

Stachys genus with medicinal properties and high polymorphic features has been considered oneof the largest genera of Lamiaceae. The aim of this study was to determine the flavonoid patternvariations and flavonoid groups in ten Stachys species belonging to two sections; Fragilicaulis,and Aucheriana. The studied species were collected from natural habitats in Iran and analysedfor their flavonoid...

the effect of postharvest uv-c irradiation on phenolic compounds accumulation was investigated in berries of ‘rishbaba’ table grape (vitis vinifera cv. rishbaba). grape clusters were harvested at mature stage and irradiated with uv-c using fluorescent germicidal lamp (30 w, 90 cm) with a peak emission at 254 nm for 0 (control), 5 and 10 min. uv-c treatment had significant effect on individual p...

Phytochemical investigations of Cotinus coggygria Scop. wood, a medicinal and tinctorial plant used since antiquity, resulted in the isolation and structure elucidation of the novel C-3/C-3'' dimer of butin (3',4',7-trihydroxyflavanone) and other known compounds: gallic acid and its methyl ester; catechin; profisetinidins: fisetinidol-(4α→8)-(+)-catechin and epifisetinidol-(4β→8)-(+)-catechin; ...

BACKGROUND Amiodarone (AMD) and its metabolite N-desethylamiodarone can cause some adverse effects, which include pulmonary toxicity. Some studies suggest that mitochondrial dysfunction and oxidative stress may play a role in these adverse effects. Catechin and epicatechin are recognized as important phenolic compounds with the ability to decrease oxidative stress. Therefore, the aim of this st...
