Abstract
Two new flavone glycosides were isolated from the seeds of Impatiens balsamina L. and their structures were determined as quercetin-3-O-[α-l-rhamnose-(1 → 2)-β-d-glucopyranosyl]-5-O-β-d-glucopyranoside (1), and quercetin-3-O-[(6‴-O-caffeoyl)-α-l-rhamnose-(1 → 2)-β-d-glucopyranosyl]-5-O-β-d-glucopyranoside (2) on the basis of various spectral and chemical studies.
