A new steroidal glycoside from <i>Corypha taliera</i> Roxb., a globally endangered species

<div><p>The reversed-phased HPLC analysis of the methanol extract of the pericarp of <i>C. taliera</i> Roxb. (Talipalm), a rare species of Arecaceae family, afforded a new steroidal glycoside, β-sitosterol-3-O-α-l-rhamnopyranosyl-(1→4)-β-d-xylopyranosyl-(1→4)-β-d-glucopyranosyl-(1→4)-β-d-glucopyranoside (<b>1</b>). The structure of the compound was elucidated unequivocally by UV, IR, HR-ESI-MS, <sup>1</sup>H and <sup>13</sup>C NMR spectroscopic studies.</p></div>
