Isolation and Structural Determination of a New Methylated Triterpenoid from Rhizomes of Iris versicolor L.

Abstract

A monocyclic C₃₁-triterpenoid was isolated from rhizomes of Iris versicolor L. Its structure was elucidated as 12 by spectroscopy combined with oxidative degradation. The identity of the degradation-products was proven by comparison with synthetic references.
