3. We reported in this short note the isolation and identification of plumbagin from a plant indigenous to New Caledonia. Although identified previously from the plant "plumbago" this is the first time it has been found in Diospyros olen. New Caledonia was part of the ancient megacontinent "Gondwanaland" which split into parts of present day Antarctica, Chile, New Zealand, New Caledonia, Australia, New Guinea and other small isolated islands. While the original plant source of this compound, plumbago, is indigenous to the old world it is still retained in related plants after a possible 350 million years. It is estimated that New Caledonia has been separated from Gondwanaland for about 260 million years and allowing for the separation of the new and old worlds of an additional 100 million years yet this same chemistry is conserved as a very potent antibiotic which doubtless protects plants from numerous pathogens.
