ABSTRACT
<p><b>OBJECTIVE</b>To study the compounds from the whole plant of Galium aparine var. tenerum.</p><p><b>METHOD</b>The various column chromatographic techniques were applied to isolate the chemical constituents. MS, NMR and 2D-NMR spectroscopic techniques were uesd to identify chemical structures.</p><p><b>RESULT</b>Six compounds were isolated from the EtOAc-soluble part of the 95% ethanol extract of the plant, and their chemical structures were identified as 1-(4-hydroxyphenyl)-ethanone (1), vanillic acid (2), 3,4-dihydroxybenzoic acid (3), p-hydroxycinnamic acid (4), gallic acid (5), 4-hydroxytruxillic acid (6).</p><p><b>CONCLUSION</b>The NMR data of compound 6 were completely assigned by 2D-NMR techniques, including 1H-1H COSY, HMQC and HMBC spectra. This was the first time to report isolation of the compound 6 from natural product. The compounds 1-5 was isolated from the genus Galium for the first time.</p>
