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 1D TOCSY, HSQC, HMBC and DQF-COSY.
从欧洲白桦内皮的甲醇水提取物中分离出两种苯丁类化合物,7-{3R-[(4-羟基苯基)丁基]β-D-吡喃葡萄糖苷氧基-6-基}-4-O-β-D-吡喃葡萄糖基香草醛和3-β-D-吡喃葡萄糖苷氧基-1-(4-羟基苯基)丁酮。通过核磁共振光谱和质谱确定了它们的结构。通过一维和二维核磁共振实验实现了质子和碳信号的完全归属:选择性一维全相关谱、异核单量子相干谱、异核多键相关谱和双量子滤波相关谱。
