Objective:
To study the chemical constituents of the Ixeris chinensis .
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 Methyl-4-hydroxyphenylacetate (1), Daucosterol (2), Sitosterol (3), Luteolin-7-O-beta-D-glucoside (4), 15-hydroxy-2-oxoguaia-1 (10), 3,11 (13)-triene-12,6-lactone (5), Chinensiolide B (6), Chinensiolide E (7), Ixerochinoside (8), Chinensiolide C (9), 10alpha-hydroxy-guaia-4(15)-ene-12,6-lactone (10), 10alpha-hydroxy-guaia-4 (15), 11 (13)-diene-12,6-lactone-3beta-O-beta-D-(6'-p-hydroxyphenylacetyl) glucopyranoside (11), Epiloliolide (12), Apigenin-O-beta-D-glucopyranoside (13), Luteolin (14), Lutein (15).
Conclusion:
Compounds 1,10,11,12 and 15 are isolated from this plant for the first time.
