Abstract
Two new eremophilane sesquiterpenes, 12-oxa-1β, 5β,8,9aβ-tetramethyl-4α,5-ethano-4aβ-hydroxy-7β,10aβ-epoxy-9β-angeloyloxy-1,2,3,4,4a,5,6,7,9,9a,10,10a-dodecahydro-anthracen-13-on (knorringianalarin A, 1) and 6,9-dien-8-oxoeremophil-12-nor-11-ketone (knorringianalarin B, 2), and a new resorcinol, 4-acetyl-6-(2-methylpropionyl)-1,3-resorcinol (knorringianalarin C, 3) were isolated from the roots and rhizomes of Ligularia knorringiana, together with three known eremophilane sesquiterpenes (4–6). The structures of the new compounds were identified by spectroscopic methods including 2D-NMR techniques.
