Bioactive natural compounds

Four isoflavone glycosides were isolated from the rhizomes of Iris germanica. Compounds 1 and 2 are new, while compounds 3 and 4 are known isoflavone glycosides. These compounds were identified as iriskashmirianin 4′-O-β-D-glucoside (1), nigricin 4′-O-β-D-glucoside (2), irilone 4′-O-β-D-glucoside (3) and iridin (4). Their structures were determined with the help of spectroscopic methods.
