Abstract

A new acylated γ-pyrone glucoside was isolated from the leaf extract of Gordonia axillaris (Theaceae), and was characterized as 3-O-(6'-O-galloyl)-β-D-glucopyranosylmaltol (7) based on two-dimensional NMR experiments and other spectroscopic analyses. 5-O-(6'-O-Galloyl)-β-D-glucopyranosylgentisic acid (6), and two dimeric hydrolyzable tannins [camelliin B (4) and schimawalin B (5)] were also isolated.
