Silica gel column chromatography and preparative HPLC were applied to isolate the chemical constituents from roots of Ixeris chinensis. Fifteen compounds isolated their structures elucidated by physicochemical properties spectral analysis as chinensioide G(1), B(2), 10α-hydroxy-guaia-12,6-lactone-3-keton(3), C(4), 10α-hydroxy-11βH-guaia-4(5) -ene-12,6-lactone (5), 3β, 10α-dihydroxy-11βH-guaia-11 (13)-ene-12,6-lactone (6), 10α-dihydroxy-4βH, 11βH-guaia-12,6-lactone(7), 10α-dihydroxy-guaia-4 (15), 11 (13) -diene-12, 6-lactone (8), caffeic acid (9), p-hydorxyphenylacetic acid(10), methyl p-hydroxyphenylacetate (11), ethyl (12), sitosterol (13), daucosterol (14), ixerin D(15). Compound 1 was new, 6 7 I. chinensis for first time.
