A new flavonol glycoside which has been isolated from the Tridax procumbens Linn. The present work deals with the isolation and identification of flavonol glycoside, characterised as 8,3′-dihydroxy-3,7,4′-trimethoxy-6-0-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside flavonol. Its structure elucidated using spectral data.
