Abstract

From the leaves of Brassica juncea, a new rare kaempferol 7-Ο-triglucoside isolated and characterized as kaempferol 7-Ο-$\beta$-D-glucopyranosyl-(1longrightarrow3)-[$\beta$-D-glucopyranosyl-(1longrightarrow6)]-glucopyranoside (1) based on the spectroscopic evidences. This compound was found to be a scavenger of 1, 1-diphenyl-2-picrylhydrazyl radical.
