CRYPTOCARYA LIEBERTIANA AND OCOTEA-BULLATA - THEIR PHYTOCHEMICAL RELATIONSHIP

Isolation of the major components from the bark of mature Cryptocarya liebertiana shows that ocobullenone and its precursor (both previously isolated from Ocotea bullata) are present in detectable concentration s in this source. These particular compounds are absent in other South African Cryptocarya species. The result is significant since Cryptoca rya bark is currently being utilized by traditional healers as an alte rnative to O. bullata bark. Copyright (C) 1997 Elsevier Science Ltd
