Flavonoid constituents of the mature fruit of Tetrapleura tetraptera schum. Et Thonn.)
Abstract
Phytochemical investigation of the ethanolic extract of the mature fruit of Tetrapheura tetraptera led to the isolation of three flavonoid constituents namely 2', 4, 4'-trihydroxychalcone, 2', 3, 4, 4'- tetrahydroxychalcone and 4', 5, 7-trihydroxyflavanone. The structures were established from 1D and 2D NMR experiments. This is the first isolation of flavonoid constituents in the genus Tetrapleura.
Keywords: tetrapheura tetraptera, flavonoid, chalcone, flavanone, 1D and 2D NMR.
