Chromene and Prenylated Xanthones from the Roots of Cratoxylum formosum ssp. pruniflorum

Abstract

Two new xanthones, namely pruniflorone K (1) and L (2), have been isolated from the roots of Cratoxylum formosum ssp. pruniflorum, along with thirteen known xanthones (3—15). Their structures were mainly established using the spectroscopic methods. Only isolated compounds with sufficient amount were evaluated for antibacterial and antifungal activities.
