Abstract: Aim To investigate the chemical constituents of Ixeris sonchifolia Hance. Methods The chemical constituents were isolated by various column chromatographic methods and the structures were elucidated and characterized by spectral evidences. Result Thirteen compounds were obtained and identified as 3β-acetoxy-20-taraxasten-22-one (1), bauerenyl acetate (2), 3β-acetoxy-11-oxours-12-ene (3), oleanic acid (4), oleanane (5), 8-desoxyartelin (6), aesculetin (7), ferulic acid (8), vanillic acid (9), sonchifolinin (10), hexacosanol (11), β-sitosterol (12), and daucosterol (13). Conclusion Compounds 1, 5, and 8 were isolated from this genus for the first time; compound 7 was obtained firstly from this plant.
