Furanoeremophilane-6β,10β-diol and Its Derivatives. New Furanosesquiterpenes from <i>Ligularia japonica</i> LESS

Abstract

Abstract Three new furanosesquiterpenes have been isolated from Ligularia japonica LESS., and their structures including absolute configurations have been determined as furanoeremophilane-6β-diol (1), 10β-hydroxyfu-ranoeremophilan-6β-yl 2′ξ-methylbutanoate (2), and 10β-hydroxy-6β-methoxyfuranoeremophilane (3).
