摘要：

Five new saponins, ilexosides XLI-XLV, were isolated from fresh leaves of Ilex rotunda, and their structures were elucidated on the basis of chemical and physicochemical evidence. Ilexoside XLI is rotundic acid 28-O-alpha-D-glucopyranosyl (1 --> 6)-beta-D-glucopyranoside, ilexoside XLII is 23-oxorotungenic acid 28-O-beta-D-glucopyranoside, ilexoside XLIII is 30-hydroxyrotundic acid 28-O-beta-glucopyranoside, ilexoside XLIV is 3,28,bis-O-beta-D-glucopyranosyl ilexosapogenin B (3-O-beta-D-glucopyranosyl 23,30-dihydroxyursolic acid 28-O-beta-glucopyranoside), and ilexoside XLV is 24-hydroxyrotundioic acid 28-O-beta-D-glucopyranoside.
