Abstract

Two new indole alkaloids, kopsiyunnanines J1 and J2, were isolated from Yunnan Kopsia arborea, and their structures were determined by spectroscopic analyses. Kopsiyunnanines J1 and J2 are unprecedented Strychnos-Type indole alkaloids having an additional C1 unit in the secologanin moiety of the molecule.
