A new alkaloid glycoside from the rhizomes of <i>Aristolochia fordiana</i>

<div><p>A new alkaloid glycoside named fordianoside (<b>1</b>), together with three known compounds arabinothalictoside (<b>2</b>), 6-<i>O</i>-<i>p</i>-coumaroyl-β-fructofuranosyl-(2 → 1)-α-d-glucopyranoside (<b>3</b>) and 4-[formyl-5-(hydroxymethyl)-1<i>H</i>-pyrrol-1-yl] butanoic acid (<b>4</b>), was isolated from the rhizomes of <i>Aristolochia fordiana</i>. The structure of <b>1</b> was established as (1<i>S</i>)-1,2,3,4-tetrahydro-7-hydroxy-1-[(4-hydroxybenzyl) methyl]-2,2-dimethyl-8-<i>O</i>-isoquinolinyl β-d-glucopyranoside by using chemical and spectroscopic methods including HR-ESI-MS, 1D and 2D NMR.</p>
