Two phenylbutanoids, 7‐{3 R ‐[(4‐hydroxyphenyl)butyl] β‐glucopyranosid‐ O ‐6‐yl} 4‐ O ‐β‐glucopyranosylvanillin and 3‐β‐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 1D TOCSY, HSQC, HMBC and DQF‐COSY. Copyright © 2007 John Wiley & Sons, Ltd.
