Two new galloyl glucosides, furan-2-carbonyl 6-C-β-D-(6'-O-galloyl)glucopyranoside (1), grasshopper ketone 5-O-β-D-(6'-O-galloyl)glucopyranoside (2), and one known compound 4-quinolone-2-carboxylic acid, were isolated from ethanol extract of the fresh leaves of Castanopsis fordii (Fagaceae). The chemical structures of these compounds were determined by one and two dimensional (1D and 2D)-NMR, liquid chromatography/time-of-flight/mass spectrometry (LC/TOF/MS), chemical evidence, and comparison with the literature.
