Jokela and Lounasmaa presented and C-NMR exact spectral data for seven types of ajmaline-type alkaloids from various species of the Dogbane family. These alkaloids are as follows ajmaline, 17-O-acetylajmaline, iso-ajmaline, isosandwichine, rauflorine, vincamajine, and vincamedine. Four steroidal alkaloids (conessine, holadysenterine, isoconessimine, and kurchessine) were found in the stem bark of Holarrhena antidysenterica Eleven indole alkaloids were isolated from the stem bark of Kopsia hainanensis Tsiang, which is a species of Kopsia, endemic in China. They are (—)-kopsinine, (—)-kopsinnic acid, (—)-kopsinoline, kopsinilam, kopsanome, (-h)-5,22-dioxokopsane, ebumamenine, (-i-)-ebumamine, (—)-isoebumamine, (-i-)-tubotaiwine, and (-i-)-kopsoffine.
