Abstract
|
|
|
|
High-performance liquid chromatographic method with diode-array detector and electrospray ionization with multi-stage tandem mass spectroscopy (HPLC/DAD/ESI-MSn) was used to identify the major constituents in a methanolic extract of Eclipta prostrata. The chromatographic separation was performed on a C18 column. Acetonitrile-water was used as a mobile phase. HPLC/DAD/ESI-MSn allowed the characterization of constituents of E. prostrata, mainly triterpenoids (eclalbasaponin I, Ⅱ, Ⅲ, Ⅳ, Ⅵ), flavonoids (luteolin 7-O-glucoside, demethylwedelolactone, wedelolactone, luteolin, demetylwedelolactone sulfate, luteolin sulfate, apigenin sulfate) and phenolic acids (5-O-caffeoylquinic acid, 3, 4-O-dicaffeoylquinic acid, 3, 5-O-dicaffeoylquinic acid, 4, 5-Odicaffeoylquinic acid).
