OBJECTIVE
To study the chemical constituents of the flower buds of Daphne genkwa.
METHODS
The constituents of petroleum ether and ethyl acetate-soluble portions were isolated and purified by means of chromatography, then they were identified by their physico-chemical characteristics and spectral
Four flavonoids including luteolin, apigenin, 3'-hydroxygenkwanin and genkwanin were isolated and purified from Daphne genkwa Sieb. et Zucc. by high-speed countercurrent chromatography (HSCCC). Preparative HSCCC with a two-phase solvent system composed of n-hexane-ethyl acetate-methanol-water
A sensitive UHPLC-MS/MS approach was developed and validated for the quantification of genkwanin, 3'-hydroxygenkwanin, apigenin, luteolin, yuanhuacine and genkwadaphnin in biological samples after oral administration of raw and vinegar-processed Daphne genkwa. Liquiritin and glycyrrhetinic acid were
