A novel bieremophilanolide from Ligularia lapathifolia.
A new bieremophilanolide was isolated from the roots and rhizomes of Ligularia lapathifolia. Its structure was established as 8,8'-bi-3beta-angeloyloxy-eremophil-7(11)-en-12,8alpha(14beta,6alpha)-diolide (1) by IR, MS, 1D, and 2D NMR experiments.
