Abstract

Three new C-glycosides, calophymembransides D-F (1-3), were isolated from the stems of Calophyllum membranaceum Gardn. et Champ.. The structures were assigned on the basis of spectroscopic data. RXRα transcriptional inhibition and α-glucosidase inhibition assays indicated that all the isolates were inactive.

Keywords: C-glycosides; Calophyllum membranaceum; calophymembranside D; calophymembranside E; calophymembranside F.
