Fourteen aristolochic acid derivatives: ariskanins A-E, 3-hydroxy-4-methoxy-10-nitrophenanthrene-1-carboxylic acid methyl ester, aristolochic acid-II methyl ester, aristolochic acid-IV methyl ester, aristolochic acid-C, -I, -II, -III, -IV, -IVa; nine aristolactam alkaloids: aristolactam, aristolactam-AII, -BIII, -AIII, -III, cepharanone-A, 9-methoxy-aristolactam-I, aristolactam-N-beta-D-glucoside and aristolactam-C-N-beta-D-glucoside; a 4,5-dioxoaporphine alkaloid: cepharadione-A, together with 12 other compounds: methyl-p-coumarate, N-trans-feruloyltyramine, N-cis-feruloyltyramine, methyl vanillate, methyl paraben, allantoin, an octadecyl- and eicosyl ferulate mixture, cis- and trans-p-coumaric acid, N-p-coumaroyltyramine, N-p-cis-coumaroyltyramine, methyl ferulate and isorhamnetin-3-O-rutinoside were isolated and characterized from the fresh root and stem of Aristolochia kankauensis. Their structures were elucidated by spectral and chemical methods. Among them, ariskanins-A-E and N-p-cis-coumaroyltyramine are reported for the first time from a natural source. The cytotoxicity and antiplatelet activity of the compounds isolated are also discussed.
