(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>
