Abstract

A new isoflavonoid glycoside, 5-hydroxy, 8,5'-dimethoxy-5-O-isoflavone glycoside, together with irisflorentin, irisolone, irisolone-4'-diglucoside, iristectorin A and irisxanthone were isolated and characterized from the rhizomes of Iris germanica L. var. alba. A flavone-C-glycoside, swertisin, xanthone glycosides mangiferin and isomangiferin were isolated from the leaves of Iris germanica L. var. alba. Two isoflavones irisolidone and irigenin together with an isoflavone glycoside iridin were isolated from the rhizomes of Iris pseudacorus L.
