摘要：

A novel clerodane-type diterpene with a 6,7-oxirane group has been isolated from Croton megalocarpus. Structure elucidation has been achieved by a combination of spectroscopic measurements including 2D NMR and NOE experiments. In addition, 3-O-acetoacetyl lupeol, a novel triterpene ester, the triterpene O-acetyl aleuritolic acid, and long chain esters of E-ferulic acid with C24-, C26- and C28-alcohols were also isolated and characterized by spectroscopic methods.
