Objective: To study the chemical constituents of Alternanthera philoxeroides (Mart.) Griseb. Methods: A variety of chromatographic techniques were used to separate and the structure of each compound was analyzed using modern spectroscopic techniques. RESULTS: Sixteen compounds were obtained and identified, which were ursolic acid (1), indole-3-carbaldehyde (2), indole-3-carboxylic acid (3), p-coumaric acid (4), and quinoline. Acid (5), N-trans feruloyl tyramide (6), Blumol A (7), 2-hydroxy-3-methylanthraquinone (8), methyl isoorientin-1-alpha Ether (9), Methylisoquercitrin (10), Quercetin (11), Luteolin (12), Coielicin-6-C-β-Boivins-7-O-β-pyrazole Glucoside (13), alendinin (14), stigmasterol (15) and α-spinasterol (16). Conclusion: Compounds 1-13 were isolated from this plant for the first time.
