[Studies on the triterpenoids of Vitex trifolia].
OBJECTIVE
To study the chemical constituents of Vitex trifolia.


METHODS
Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.


RESULTS
Five triterpenoids were obtained and identified as ursolic acid (I),2alpha,3alpha-dihydroxyurs-12-en-28-oic acid (II), betulinic acid (11), taraxerol (IV), 2alpha,3beta, 19-trihydroxyurs-12-en-28-oic acid (V).


CONCLUSIONS
Compounds 1-5 are isolated from this plant for the first time.
