[Studies on chemical constituents in leafs of Ilex kudingcha].
OBJECTIVE
To study chemical constituents of Ilex kudingcha.


METHODS
The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral analysis.


RESULTS
Seven compounds, lupeol(I); 3 beta-hydroxyl-lup-20(29)-ene-24-methyl ester(II); lup-20(29)-ene-3 beta-, 24-diol(III); beta-sitosterol(IV); ursolic acid(V); daucosterol (VI); mannitol were obtained(VII).


CONCLUSIONS
I, III, VI and VII compounds were obtained from genus Ilex for the first time.
