Abstract
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.
