Abstract

Phytochemical studies on the bark ofArtabotrys pleurocarpushave yielded seven isoquinoline alkaloids; liriodenine (1), lanuginosine (2), atherospermidine (3), lysicamine (4), asimilobine (5), isocorydine (6) and N-methylcoclaurine (7).  The isolation of the alkaloids was achieved by chromatographic techniques and the structural elucidations were performed via spectral methods; namely 1D and 2D NMR, IR, UV and MS.
