Abstract Fifteen compounds were obtained from the extract of the whole herbs of Aristolochia tagala, which were divided into eight aristolactam-type alkaloids (1–6, 14 and 15) and seven aristolochic acid derivatives (7–13). Their structures were identified as aristolactam BII, aristolactam II, sauristolactam, aristolactam I, 7-methoxyaristolactam IV, aristolactam AII, 3-hydroxy-4-methoxy-10-nitrophenanthrene-1-carboxylic acid methyl ester, ariskanin A, ariskanin D, ariskanin E, aristolochic acid C, ariskanin C, ariskanin B, aristolactam-N-β-D-glucoside and cepharanone A N-β-D-glucoside by comparison of their spectral data with those reported previously in the literature. The chemotaxonomic relationships between A. tagala and other species of genus Aristolochia were also discussed. As a result, the isolated compounds closely matched the ones obtained in other species of the genus.
