Xanthones from Drimiopsis maculata

Abstract

Six new xanthones, drimiopsins A-F (1-6), have been isolated from the South African Drimiopsis maculata. The structures of these compounds were difficult to elucidate due to the lack of correlating protons seen in the NMR spectra, and INADEQUATE spectra were used to confirm the structures. Xanthones have not previously been reported from the Hyacinthaceae.
