The phytochemical studies on the bark of Cyathostemma wrayi King resulted in the identification of ten alkaloids consisting of four oxoaporphines; lysicamine (1), atherospermidine (2), thalicminine (3), liriodenine (4), five aporphines; xylopine (5), nornuciferine (6), annonaine (7), norstephalagine (8), asimilobine (9), and one propaporphine; stepharine (10). The structural characterisation of all the isolated alkaloids was confirmed through the analysis of spectroscopic data and comparison with literature data. This is the first report on the alkaloids of Cyathostemma wrayi and also the first report on the occurrence of aporphine (1-3) and proaporphine (5-10) alkaloids in the genus of Cyathostemma. In addition, the chemophenetic significance of the isolated alkaloids was summarized.
