Abstract: A new flavone glycoside 1 molecular formula C32H38O19, m.p. 246-48°C, [M]+ 726 (FABMS), has been isolated from seeds of Emilia sonchifolia 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 2 and Isoetin 5′-methyl ether 3.
