Two new flavone glycosides from the seeds of Impatiens balsamina L.
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.
