Abstract: A new flavone glycoside <b style="">1</b> molecular formula C<sub>32</sub>H<sub>38</sub>O<sub>19</sub>, m.p. 246-48°C, [M]<sup>+ </sup>726 (FABMS), has been isolated from seeds of <i style="">Emilia sonchifolia</i> DC. It has been characterized as 3,7,3′,4′-tetrahydroxy-flavone-3-O-β-d-xylopyranosyl-(1→3)-O-β-d-gal­actopyranosyl-(1→4)-O-α-l-rhamnopyranoside by various chemical degradations and spectral analysis alongwith two known compounds Luteolin-7-O-β-d-glucoside <b style="">2</b> and Isoetin 5′-methyl ether <b style="">3</b>.
