Two new isoflavonoid biosides, tectorigenin 4'-glucosyl(lā6)glucoside and iristectorigenin B 7-glucosyl(1ā6)glucoside, a new isoflavonoid monoside, 4'-methyltectorigenin 7-glucoside and a new flavone glucoside, 6,4'-dimethoxy-5-hydroxyflavone 7-glucoside, together with tectoridin and tectorigenin 4'-glucoside were isolated from rhizomes of Iris carthaliniae. The structures of the isolated compounds were determined by NMR spectral analysis.
