[Studies on the chemical constituents from Daphne tangutica].
OBJECTIVE
To research the chemical constituents from Daphne tangutica.


METHODS
Column chromatography with silica gel, ODS-C18, Sephadex LH-20 and re-crystallization were employed to isolate and purify the constituents. According to physical and chemical properties and spectral data to identify the structure of compounds.


RESULTS
Eight compounds were isolated and identified as palmitic acid (1), laurostearic acid(2), beta-sitosterol(3), 7-methoxy-8-hydroxycumarin(4), daphnetin(5), genkwanin(6), hydroxygenkwanin(7), p-hydroxybenzoic acid(8).


CONCLUSIONS
Compounds 1,2,7 and 8 are isolated from Daphne tangutica for the first time.
