Objective To study the chemical constituents in 95% ethanol aqueous extract of Chuanxiong Rhizoma. Methods The compounds were separated and purified by repeated column chromatography on silica gel and high performance liquid chromatography, and their structures were determined by spectroscopic data analyses. Results Forty-one compounds were obtained. Among them, 34 compounds were identified as xanthotoxin(1), 3-butylidenephthalide(2), Z-ligustilide(3), senkyunolide A(4), senkyunolide H(5), senkyunolide I(6), coniferyl alcohol(7), 3-propylanisole(8), epoxyligustilide(9), 5-hydroxy-3-butylene-phthalide(10), chuanxiongdiolide R1(11), neocnidilide(12), Z′-3,8-dihydro-6.6′,7.3′a-diligustilide(13), tokinolide B(14), ansaspirolide(15), bergaptol(16), senkyunolide D(17), 4-hydroxy-3-butyl-phthalide(18), 5-hydroxymethylfurfural(19), vanillin(20), levistolide A(21), trans-ferulic acid(22), 4-hydroxy-3-methoxypropiophenone(23), ethyl ferulate(24), falcarindiol(25), oplopandiol(26), senkyunolide E(27), stigmasterol(28), pregnenolone(29), isopimpinellin(30), β-sitosterol(31), dibutylphthalate(32), diisobutylphthalate(33), and coniferyl aldehyde(34), respectively. Conclusion Compounds 1, 8, 16, 23, 26, and 30 are isolated from Chuanxiong Rhizoma for the first time.
