[Studies on chemical constituents of Ilex Merr].

OBJECTIVE: To further probe into the chemical composition of Ilex hainanensis.

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

RESULT: 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.

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