AI Article Synopsis
- Two new iboga-type indole alkaloids were identified from the twigs and leaves of the Tabernaemontana divaricata plant.
- The newly discovered compounds are (3R)-7,19-di-epi-3-methoxytabernoxidine and (3R,19R)-19-hydroxy-3-(2-oxopropyl)voacangine.
- Their structural identities were confirmed through various scientific methods, including spectroscopic techniques, X-ray diffraction, and circular dichroism analysis.
Article Abstract
Two hitherto unknown iboga-type indole alkaloids, namely (3R)-7,19-di-epi-3-methoxytabernoxidine (1) and (3R,19R)-19-hydroxy-3-(2-oxopropyl)voacangine (2), together with eight known alkaloids (3-10), were isolated from the twigs and leaves of Tabernaemontana divaricata. Their structures were established on the basis of spectroscopic data interpretation, single crystal X-ray diffraction analysis and circular dichroism spectrum.
