Abstract

A new fernane-type triterpene, named integrifolin (1), was isolated and characterized from the aerial parts of Teucrium integrifolium. The structure of the new compound was deduced to be 3β-hydroxy-fern-9(11)-en-23-oic acid through its spectral properties and X-ray crystallographic analysis.
