Abstract

A pair of new diastereoisomeric flavan, containing an additional phenylpropanoid (C6-C3) unit in the molecule, has been isolated from the leaves of Ilex centrochinensis. Their structures were identified by extensive spectral analysis and comparison with the data of known analogues.

Keywords: Ilex centrochinensis; diastereoisomer; flavan; phenylpropanoid.
