摘要

Nuclear magnetic resonance (NMR) spectroscopic analysis of metabonome/metabolome has wide-spread applications in biomedical science researches. However, most of NMR resonances for urinary metabolites remain to be fully assigned. In the present study, human urine samples from two healthy volunteers were pre-treated with C18 solid-phase extraction and the resultant 5 sub-fractions were subjected to one- and two-dimensional NMR studies, including 1H J-Resolved, 1H-1H COSY, 1H-1H TOCSY, 1H-13C HSQC, and HMBC 2D NMR. More than 70 low molecular weight metabolites were identi-fled, and complete assignments of 1H and 13C resonances including many complex coupled spin sys-terns were obtained.
