| Description | Echinatin is a chalcone isolated from the Chinese herbal medicine Gancao with hepatoprotective and anti-inflammatory effects. Echinatin may undergo an electron transfer (ET) and a proton transfer (PT) to cause the antioxidant action in aqueous solution[1]. Echinatin can be quickly absorbed and eliminated and extensively distributed with an absolute bioavailability of approximately 6.81% in Rat[2]. |
