[Studies on chemical constituents in leafs of Ilex kudingcha].Zhongguo Zhong Yao Za Zhi. 2003 Sep; 28(9):834-6.ZZ
To study chemical constituents of Ilex kudingcha.
The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral analysis.
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).
I, III, VI and VII compounds were obtained from genus Ilex for the first time.
