Abstract:
OBJECTIVE: To study the chemical constituents of Ixeris chinensis Nakai. METHODS: The constituents were isolated by silica gel column chromatography, HPLC and recrystallization, and their structures were elucidated on the basis of spectral analysis. RESULTS: Fifteen compounds were isolated and identified as Chinensioide F(1), Chinensioide C(2), daucosterol(3), 6'-phydroxyphenylacetyl-Ixerin D(4), methyl-4-hydroxyphenylacetate(5), p-hydroxyphenylethanol(6), 3,5-dimethoxy-4-hedroxyphenylpropynol(7), 10α-hydroxy-guaia-12,6-lactone-3-keton(8), sitosterol(9), Chinensioide E(10), Chinensioide D(11), Ixerochinoside(12), 3β,10α-dihydroxy-guaia-4(15), 11(13)-diene-12,6-lactone(13), 10α-hydroxy-11βH-guaia-4(15)-ene-12,6-lacton(14) and luteolin-7-O-β-D-glucoside(15). CONCLUSION: Compound 1 is new (chinensiode F). Compound 4~7 and 12~14 were isolated from I. chinensis Nakai for the first time.
