摘要：

An investigation on the constituents of the fresh, uncrushed leaves of Eucalyptus camaldulensis var. obtusa has led to the isolation of the triterpenoid amirinic acid and four known triterpenoids ursolic acid lactone, betulinic acid, oleanolic acid and ursolic acid. Amirinic acid transformed into amirolide in deuterated chloroform at room temperature. The new products were characterized by exhaustive spectroscopic studies as 2 alpha,3 beta,7 beta-trihydroxy-11 alpha-methoxyurs-12-en-28-oic acid and 2 alpha,3 beta,7 beta-trihydroxyurs-11-en-28,13 beta-olide.
