Magn Reson Chem. 2010 Apr;48(4):304-8. doi: 10.1002/mrc.2578.

Abstract

Two new acylated flavonol glycosides, 3-O-{[2-O-beta-D-glucopyranosyl]-3-[O-beta-D-glucopyranosyl]-4-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]}-alpha-L-rhamnopyranosyl-kaempferol 7-O-alpha-L-rhamnopyranoside and 3-O-{2-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]-3-[O-beta-D-glucopyranosyl]-4-[(6-O-p-coumaroyl)-O-beta-D-glucopyranosyl]}-alpha-L-rhamnopyranosyl-kaempferol 7-O-alpha-L-rhamnopyranoside, trivially named as brauhenefloroside E (1) and F (2), respectively, were isolated from the fruits of Stocksia brauhica and their structures were elucidated using spectroscopic methods, including 2D NMR experiments.
