J Nat Prod. 2002 Mar; 65(3):352-7.JN

Abstract

Six new flavonoid glycosides, quercetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(4-O-trans-p-coumaroyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (1), quercetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(3-O-trans-p-coumaroyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (2), isorhamnetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(4-O-trans-p-coumaroyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (3), isorhamnetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(3-O-trans-p-coumaroyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (4), isorhamnetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(4-O-cis-p-coumaroyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (5), and isorhamnetin 3-O-alpha-L-rhamnopyranosyl(1-->6)-[alpha-L-rhamnopyranosyl(1-->2)]-(4-O-trans-feruloyl)-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside (6), were isolated from the dried aerial parts of Rhazya orientalis. The structures of 1-6 were determined by spectroscopic and chemical means.
