Abstract
7,8-dimethoxy-N-methylflindersine and 7,8-dimethoxy-3-(3-methylbut-2-enyl)-2-quinoline were isolated from the stem bark of Araliopsis tabouensis and their structures were assigned base on their 1H and 13C-NMR, DEPT 135, Gradient HMBC, G-HMQC and G-DQF-Cosy characteristics. The IC50 value in antimalarial bioassays vary from 1.8 to 4.7 μg/ml.
Key words: Araliopsis tabouensis, structural determination, antimalarial properties.
