| 摘 要： | Carpesium cernuun L. has long been used as chinese folk medicine for its anti-inflammatory, pain-relief, and detoxication properties1. Up to now, no phytochemical studies of Carpesium cernuun has been carried out. Here we report the structure elucidation of a new eudesmanolide 1 and a new aromatic derivative 2, which were obtained from this plant. Compound 1 was isolated as colorless gum, (]+128.4 (c 0.43, CHCl3). Its EIMS revealed a molecular ion peak m/z 248. Together with the support …

| Abstract: | A new eudesmanolide and a new aromatic derivative were isolated from the roots of Carpesium cernuun. Their structures were elucidated as 13-hydroxy-5,7(11)-eudesmadien-12,8-olide and 3-methyl-8-acetoxy-9,10-diisobutyryloxy-p-cymene by spectral methods (EIMS, FAB-MS, 1D and 2D NMR). |
