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