Two new isoflavonoid glucosides, 5‐hydroxy‐6,7‐methylenedioxy‐isoflavone‐4′‐O‐ D ‐glucopyranosyl (2→1)‐ L ‐rham‐noside (irilone‐bioside) (compound 1) and 5,4′‐methoxy‐6,7‐methylenedioxyisoflavone‐3′‐O‐β‐ D ‐glucoside (irisleptophyllidin) (compound 2), together with five known compounds, nigricanin‐ 4′‐O‐β‐ D ‐glucoside (compound 3), irifloside (compound 4), irigenin (compound 5), 5, 3′, 4′‐trimethoxy‐6,7‐methylenedioxyisoflavone (compound 6), and nigricanin (compound 7) were isolated from the alcoholic extract of rhizomes of Iris leptophylla Lingelsh. Their structures were elucidated by spectroscopic methods.
