Abstract

Objective: To study chemical constituents of Ilex kudingcha.

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

Result: 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).

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