Abstract Six novel alkylated p-Benzoquinones irisoquin (A-F) (1-2, 4-7) together with a known cytotoxic quinone, irisoquin (3) along with three known isoflavones, tectoregenin, iristectorin and irigenin were isolated from the rhizomes of Iris kumaonensis and characterized. The structures of compounds 1-2, 4-7 were confirmed by extensive spectroscopic analysis, IR, MS, HRMS, GC, GC-MS, 1D (1H, 13C, NOE) and 2D (HMQC and HMBC) NMR and comparison with literature data of known compounds.
