Description
A further minor alkaloid obtained from the stem, stem bark, root and root bark of Cabucala fasciculata, isocarboxine B is an isomer of the preceding alkaloid. It forms an amorphous powder which cannot be crystallized and has no definite melting point. It is dextrorotatory with a specific rotation of [α]D + 53° (c 1.0, CHC13). The structure given is based mainly upon spectroscopic evidence, particularly the ultraviolet, NMR and mass spectra.
