OBJECTIVE
To investigate the chemical constituents of Ilex pernyi.
METHODS
The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.
RESULTS
Eight triterpenoid compounds were isolated and identified as ursolic acid (1), lupeol
Ten triterpenoid glycosides, including five new ones (1-5), were isolated from the leaves of Ilex pernyi. The chemical structures of 1-5 were determined on the basis of the chemical and spectroscopic evidence.
Ilexpernoside A and ilexpernoside B, two new pentacyclic C(4)-nortriterpenoid saponins, were isolated from the leaves of Ilex pernyi Franch. Their chemical structures were determined by MS, NMR spectroscopy and chemical analysis. Complete assignments of the (1)H and (13)C NMR spectroscopic data were
