previously reported compound falcarindiol-3-monoacetate consisted of a mixture of the 3-acetate and its allylic isomer, 1-acetoxyheptadeca-2,9-diene-4,6-diyn-8-ol. The other polyacetylenic carbonyl previously identified, falcarinolone, was present only as an artifact derived from autooxidation of falcarindiol during the isolation procedure.
