Abstract

The oleoresin from Hardwickia pinnata Roxb. is shown to be a complex blend of sesquiterpenes and diterpenes. (-)-Copaene, (-)-caryophyllene and humulene account for over 90% of the sesquiterpenes present. The diterpenes, which constitute some 60% of the oleoresin, have been found to consist of a series of closely related new diterpenoids of ent-clerodane type. Evidence leading to the elucidation of the absolute stereostructure of the main diterpenoid-hardwickiic acid-is presented.
