(-)-Epicatechin gallate

SKU: orb1226662

Description

(-)-Epicatechin gallate is a flavan-3-ol, a type of flavonoid, present in green tea.(In Vitro):(-)-Epicatechin gallate (Epicatechin gallate) exhibits >95% inhibitory activity at 70 μg/mL against cyclooxygenase-1 (COX-1) with an IC50 of 7.5 μM.(In Vivo):(-)-Epicatechin gallate (Epicatechin gallate), a component of Rhei Rhizoma, is one of the active components of Onpi-to, a herbal medicine composed of five crude drugs (Rhei Rhizome, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma and Aconiti Tuber). Following intravenous injection of (-)-Epicatechin gallate (1.0 mg/kg) in rats, the plasma concentration vs. time curve is fitted in a three compartment model. Pharmacokinetic parameters for plasma Epicatechin gallate (ECG) are measured. ECG has a t1/2α of 0.038 h, a t1/2βof 0.291 h and a t1/2γ of 4.033 h . The CLtot of ECG is 4.19 L/h kg. The Vdss is 12.39 L/kg.
