34221-41-5 - Reference Information
| Plant source: | Licorice |
| biological activity | Echinatin is isolated from the Chinese herbal medicine licorice, chalcone, which has liver-protecting and anti-inflammatory effects. The Echinatin causes antioxidation through electron transfer (ET) and proton transfer (PT) in aqueous solution. In rats, Echinatin can be quickly absorbed and eliminated and widely distributed, with an absolute bioavailability of about 6.81%. |
| uses | prickly licorice chalcone has anti-tumor, liver-protecting and anti-inflammatory effects. used for content determination/identification/pharmacological experiment, etc. |
