Furanoeremophilanes from Ligularia atroviolacea.
A new furanoeremophilane, 1alpha-chloro-6beta-isobutyroxy-9-oxo-10beta-hydroxy-furanoeremophilane (1) was isolated from the root of Ligularia atroviolacea and identified mainly on the basis of detailed spectral analyses including X-ray. Moreover, five known furanoeremophilanes,1alpha-hydroxy-6beta-isobutyroxy-9-oxo-10beta-H-furanoeremophilane (2), 1alpha-hydroxy-6beta-isobutyroxy-9-oxo-10alpha-H-furanoeremophilane (3), 1alpha,10beta-dihydroxy-6beta-angeloyloxy-9-oxo-furanoeremophilane (4), furanoeremophil-3-en-15,6alpha-olide (5) and furanoeremophil-15beta,6alpha-olide (6) were isolated from the same source.
