Two phenylbutanoids, 7-(3R-[(4-hydroxyphenyl)butyl] beta-glucopyranosid-O-6-yl) 4-O-beta-glucopyranosylvanillin and 3-beta-glucopyranosyloxy-1 -(4-hydroxyphenyl)-butanone were isolated from an aqueous methanol extract of the inner bark of Betula pendula. Their structures were determined by NMR spectroscopy and mass spectrometry. The complete assignment of proton and carbon signals was achieved by 1D and 2D NMR experiments: selective 1 D TOCSY, HSQC, HMBC and DQF-COSY. Copyright (C) 2007 John Wiley & Sons, Ltd.
