Objective:
To study the flavonoids compounds from the effective fraction of Thesium chinese in anti-inflammation.
Methods:
The isolation and purification were carried out by many kinds of column chromatographic techniques. The flavonoids were analyzed by HPLC-DAD, and elucidated by 1H-NMR, 13C-NMR and ESI-MS.
Results:
Five compounds were obtained and therir structures were determined as kaempferol-3-O-glucoside (I), rutinoside (II), luteolin-7-O-glucoside (III), kaempferyl 5-methyl ether (IV), apigenin-5-O-neohesperidoside (V).
Conclusion:
Compounds IV and V are isolated from this plant for the first time.
