A high-speed counter-current chromatography (HSCCC) method for separation and purification of coumarins from Cnidium monnieri (L.) Cusson was developed by using stepwise elution with a pair of two-phase solvent system composed of light petroleum-ethyl acetate-methanol-water at volume ratios of 5:5:5:5, 5:5:6:4 and 5:5:6.5:3.5. Five kinds of coumarins were obtained and yielded 7.6 mg of xanthoto...
A simple, specific and reproducible liquid chromatography-electrospray ionization mass spectrometry was developed and validated for the determination of jolkinolide B, a potential antitumor active component isolated from Euphorbia fischeriana, in rat plasma. Chromatographic separation was achieved on a Venusil MP-C18 column using an isocratic elution. Jolkinolide B and osthole (internal standar...
