A new guaiacylglycerol ether, threo-guaiacylglycerol-8 -vanillic acid ether, pyrocatechuic acid, pyrocatechuic acid 3-O-β-d-glucoside, gentisic acid, gentisic acid 5-O-β-d-glucoside, vanillic acid and vanillic acid 4-O-β-d-glucoside were identified from fruits of Boreava orientalis. Structural elucidation was carried out on the basis of UV, mass, 1 H and 1 3 C NMR spectral data, including 2D shift-correlation and selective INEPT experiments.
