Description

Epichatechin is one of the 4 catechin diastereoisomers. It can be isolated from a number of species of Palmae, as well as Dryas octopetala and guarana seeds. Epicatechin has been widely studied as a potential therapeutic compound in a wide variety of conditions including cancers, diabetes, heart conditions, and neurological conditions. Epicatechin is available as a natural health supplement and marketed for bodybuilding and the treatment of high blood pressure, high cholesterol, immune support, low testosterone, high blood sugar, and improved memory.

Sample Use Guides

In Vivo Use Guide
Ten adults with genetically-confirmed Becker muscular dystrophy received (-)-epicatechin 100 mg/day orally for 8 weeks.
Route of Administration: Oral
In Vitro Use Guide
HCAEC cells were obtained from 14-, 40, and 60-year old healthy male donors. Cells were maintained in HCAEC growth medium at 37 deg-C under a 5% CO2 atmosphere. Sixteen hours prior to experiments, HCAECs were washed with phenol red-free Hank’s salts solution and kept in phenol red-free M-199 supplemented with 200 mmol/L of L-glutamine and 1% antibiotic mix. To develop time response curves, cells were treated with 1 micromol/L epicatechin diluted in water. Culture media samples were collected at 0, 5, 10, 20, 30, 60, 120, 180 and 240 min. To develop concentration-response curves, cells were treated with epicatechin (0.1 nmol/L–100 μmol/L) for 10 min. Increases in NO were detected as early as 5 min after treatment, with a maximal effect occurring at 10–30 minutes and a maximal effect was obtained with 1 μmol/L epicatechin.
