Abstract

Abstract: A new and three known furanoeremophilanes were separated from Ligularia atroviolacea via chemical investigation, which were identified as 1α-chloro-6β-isobutyroxy-9-oxo-10β-hydroxy-furanoeremophilane(1), 1α-hydroxy-6β-isobutyroxy-9-oxo-10β-H-furanoeremophilane(2), 1α-hydroxy-6β-isobutyroxy-9-oxo-10α-H-furanoeremophilane(3), 1α,10β-dihydroxy-6β-angeloyloxy-9-oxo-furanoeremophilane(4). Their structures were established by spectroscopic methods including 2D-NMR. The absolute structure of compound 1 was determined by X-ray diffraction analysis.

Key words: Ligularia atroviolacea, Isolation and purification, Structure identification, Furanoeremophilane, X-ray diffraction
