It has been reported that curdione is a major component in Chinese traditional herb ezhu. But no curdione was found in the herb ezhu collected from Guangdong province, instead a furan sesquiterpene was isolated. Its structure and configuration were determined by the analysis of IR, UV, MS, NMR and circular dichroism.
