OBJECTIVE
To study effective active constituents of Cayratia japonica,a genuine herbal medicine from Fujian.
METHODS
Such chromatographic methods as Macroporous, Sephadex LH-20, ODS and normal phase silica gel column chromatography were adopted to separate the chemical components of C. japonica.
RESULTS
Thirteen compounds were obtained, and their structures were identified by analyzing multiple spectral data as luteolin(1), apigenin(2), triethyl citrate-(3), 3-formylindole(4), esculetin(5), bis(2-ethylhexyl)-phthalate(6), calendin(7), ethyl-trans-3,4-dihydr-oxycinnamate(8), luteolin7-O-D-glucoside(9),5-hydroxy-3,4-dimethyl-5-pentyl-2(5H-furanone(10),ethyl-3,4-dihydroxybenzoate(11), eriodictyol(12) and daucosterol(13).
CONCLUSIONS
Among them, compounds 3-8 and 10-12 were separated from the plant for the first time.
