Abstract

Five new di- and triglycosides, irigenin 7-[O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside] (1), 6-hydroxygenistein 4′-[O-β -D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside] (2), nigricin 4′-[O-β-D-glucopyanosyl-(1 → 6)-β-D-glucopyranoside] (3), nigricin 4′-[O-β-D-glucopyanosyl-(1 → 2)-O-[α -L-rhamnopyranosyl-(1 → 6)]-β-D-glucopyranoside] (4), and 7-{4′-{[2″-O-(4″″-acetyl-2″″-methoxyphenyl) -β-D-glucopyranosyl]oxy}-3′-(β-D-glucopyranosyloxy)phenyl] -9-methoxy-8H-1,3-dioxolo[4,5-g]-[1 benzopyran-8-one-] (5), along with a known compound, nigricin 4′-(β-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.
