Abstract

Methanol extracts from Perezia hebeclada roots yielded the new 8‐β‐D‐glucopyranosyloxy‐4‐methoxy‐5‐methylcoumarin (1) together with the known 4‐β‐D‐glucopyranosyloxy‐5‐methylcoumarin (2). Their structures were determined and verified, respectively, by MS and NMR studies, including 1D and 2D experiments. Two ^13^C NMR signals of the sugar residue of 2 were reassigned.
