[Chemical constituents of the leaves of Crataegus scabrifolia (Franch.) Rehd].
OBJECTIVE
To explore the medicinal resources of Crataegus and seek compounds with pharmaceutical effects.


METHODS
Column chromatography was employed for the isolation and purification of constituents and the structures were elucidated by spectral analysis and chemical evidence.


RESULTS
Six compounds were obtained and identified as rutin, hyperoside, vitexin, ursolic acid, daucosterol, and nonacosanol.


CONCLUSIONS
The main constituents of the leaves of Crataegus scabrifolia are flavonoids.
