ABSTRACT Two new xanthone glycosides, namely pruniflorosides A and B (1, 2), a new benzophenone glycoside, prunifloroside C (3), and a new xanthone, pruniflorone S (4) were isolated from the stems of Cratoxylum formosum ssp. pruniflorum, along with six known xanthones (5-10). Their structures were determined on the basis of extensive spectroscopic analysis. In addition, their retinoid X receptor α (RXRα) transcriptional activities were evaluated in vitro.
