Abstract

Five new di- and triglycosides, irigenin 7-[O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside] (1), 6-hydroxygenistein 4'-[O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside] (2), nigricin 4'-[O-beta-D-glucopyanosyl-(1 -->6)-beta-D-glucopyranoside] (3), nigricin 4'-[O-beta-D-glucopyanosyl-(1-->2)-O-[alpha-L-rhamnopyranosyl-(1-->6)]-beta-D-glucopyranoside] (4), and 7-{4'-[2-O-(4-acetyl-2-methoxyphenyl)-beta-D-glucopyranosyl]oxy}-3'-(beta-D-glucopyranosyloxy)phenyl]-9-methoxy-8H-1,3-dioxolo[4.5-g]-[1 benzopyran-8-one-] (5), along with a known compound, nigricin 4'-(beta-D-glucopyranoside) (6), were isolated from the rhizomes of Iris germanica. The structures of these compounds were established by spectroscopic methods, including 2D NMR spectroscopic techniques.
