Abstract
Two novel triterpenoids have been isolated from the roots of Lantana camara L.: 3 beta,19 alpha dihydroxy ursan-28-oic acid and 21,22 beta- epoxy-3 be ta-hydroxy olean-12-en-28-oic acid in its methyl ester form. Its leaves hav e yielded an essential oil which is rich in sesquiterpenes. Oleanolic acid, which is thought to be a hepatoprotective compound, was isolated from L. c amara roots and converted into its 28 --> 13 beta lactone by a facile photo -oxidation reaction.
