Influence of Gallate and Pyrogallol Moieties on the Intestinal Absorption of (−)‐Epicatechin and (−)‐Epicatechin Gallate

Journal of Food Science, 2012
Abstract:  The cellular accumulation of individual catechins was measured as an index of intestinal absorption to clarify the interactions among catechins. The cellular accumulation of (−)‐epicatechin (EC) increased in the presence of other catechins.

Insulin like activity in (−) epicatechin

Acta Diabetologica Latina, 1989
Water extract of the bark of plant of Pterocarpus marsupium Roxb is used as an antidiabetic drug in indigenous medicine in India. (-) Epicatechin, its active principle, has been found to be insulinogenic. The present in vitro study reports some insulin like activities of (-) epicatechin.

Protective Effect of Epicatechin, Epicatechin Gallate, and Quercetin on Lipid Peroxidation in Phospholipid Bilayers

Archives of Biochemistry and Biophysics, 1994
Antioxidative effect of (-)-epicatechin,(-)-epicatechin gallate, and quercetin was examined by measuring the inhibition of lipid peroxidation in large unilamellar liposomes composed of egg yolk phosphatidylcholine (PC). These catechol-type flavonoids were stable in the liposomal suspension.

Advances in physiological functions and mechanisms of (−)-epicatechin

Critical Reviews in Food Science and Nutrition, 2020
(-)-Epicatechin (EC) is a flavanol easily obtained through the diet and is present in tea, cocoa, vegetables, fruits, and cereals. Recent studies have shown that EC protects human health and exhibits prominent anti-oxidant and anti-inflammatory activities, enhances muscle performance, improves symptoms of cardiovascular and cerebrovascular diseases ...

Effects of epicatechin on rat islets of Langerhans

Diabetes, 1984
Plants containing epicatechin (a flavonoid) have been used to treat diabetes mellitus in Indian medicine. The present study reports effects of this compound on isolated islets of Langerhans. The flavonoid (1 mM) was found to increase insulin secretion from isolated rat islets of Langerhans in the presence of either 2 or 20 mM glucose, in static ...

‘Leuco-cyanidin’ and Epicatechin

Nature, 1953
Bate-Smith and Swain1 have recently come to the conclusion that the so-called condensed, ‘catechin’, tannins are in many instances identical with the ‘leuco-anthocyanins’ described by Robinson and Robinson2. Recent work here has suggested that the catechins and ‘leuco-anthocyanins’ are extremely closely related.

Epicatechin: Endothelial Function and Blood Pressure

Journal of Agricultural and Food Chemistry, 2012
Epidemiological studies indicate an inverse relationship between flavanol intake and the risk of cardiovascular disease. Potential mechanisms include their effects on endothelial function and hypertension. A number of studies have shown that flavanol-rich cocoa reduces blood pressure and endothelial dysfunction, whereas black tea may have opposite ...

Characterization of Sulfated Quercetin and Epicatechin Metabolites

Journal of Agricultural and Food Chemistry, 2012
Different monosulfates of quercetin and epicatechin with metabolic interest were obtained by hemisynthesis and characterized regarding their chromatographic behavior and absorption and mass spectra. Three of these compounds were further isolated, and their structures were elucidated by mass spectrometry and (1)H and (13)C nuclear magnetic resonance ...

Quantification of (−)-epicatechin and procyanidin B2 in chocolates

Journal of Planar Chromatography – Modern TLC, 2011
Validation of a method for the quantification of (–)-epicatechin and procyanidin B2 in chocolates is reported. After a simple preparation of the chocolate test solution, thin-layer chromatography (TLC) on high-performance thin-layer chromatographic (HPTLC) cellulose plates with n-propanol–water–acetic acid (20:80:1, v/v) and derivatization with 4 ...
