[Studies on chemical constituents of Ilex Merr].
OBJECTIVE
To further probe into the chemical composition of Ilex hainanensis.


METHODS
Compound isolation was affected on the basis of the EtOAc soluble fraction of the ethanolic extract from the leaves of the plant.


RESULTS
Four compounds were obtained and by physico-chemical and spectroscopic methods identified as ursolic acid, ilexgenin A, ilexsaponin A1 and beta-sitosterol-3-O-beta-D-glucoside.


CONCLUSIONS
All the four compounds were isolated from the plant for the first time.
