- Abstract
A new iridal, irigermanone ( 1) and nine known congeners, 2- 10, respectively, have been isolated from the dried rhizomes of German iris ( Iris germanica). The structure of 1 was established by spectroscopic methods including HR-ESI-MS, 1D- and 2D-NMR, and electronic circular dichroism (ECD) spectroscopy. Compound 1 is a structurally unique noriridal, and it possesses an unprecedented methylcarbonyl group instead of the α, β-unsaturated aldehyde function typical for this group of triterpenes.
