摘要：

A methanol extract of Cladanthus arabicus gave two sesquiterpenes. One was a new compound, cladantholide, identified as 2-oxy-1 alpha H,5 alpha H,6 beta H,7 alpha H,11 alpha H-guai-3,4-en-6,12-olide. The other compound was sintenin elucidated as 3 beta,9 beta-diacetoxy-6 beta H,7 alpha H-germaera-1(10),4(5)-diene-6,12-olide. The structures of these compounds were substantiated by high field H-1 and C-13 NMR spectroscopy. The structure of cladantholide was confirmed by single crystal X-ray diffraction.
