摘要:
Four new eremophilanolides were isolated from the rhizomes of Ligularia intermedia. Their structures were determined by spectroscopic methods and 2D-NMR techniques, to be 6 alpha,9-dihydroxy-14 beta-carboxyfuranoeremophil-9(10)-ene, 7 alpha,8 alpha-epoxyeremophilan-12 beta,8 beta(14 beta,6 alpha)-diolide, eremophil-7(11),8(9)-dien-12,8(14 beta,6 alpha)-diolide and eremophil-7(8)-en-12,8(14 beta,6 alpha)-diolide.
