摘要：

Ten new eremophilane-type sesquiterpene lactones, eremopetasitenins A1, A2, B1, B2, C1, C2, C3, D1, D2, and D3, sulphoxide bearing lactone, eremopetasinsulphoxide, and two methoxyl derivatives, as well as seven previously known sesquiterpenes have been isolated from fresh rhizomes of Petasites japonicus and their structures determined by spectroscopic techniques. Epoxyeremophilanolides, eremopetasitenins Al, A2, B1, and B2, are proposed to be important biogenetic intermediates. (C) 1997 Elsevier Science Ltd. All rights reserved.
