From the fresh leaves of Ilex rotunda, were isolated four new saponins named ilexosides XXIX-XXXII, together with the known saponins pedunculoside, ziyu-glycoside I, suavissimoside F1 and chikusetsusaponin IVa. Their structures were established on the basis of spectral and chemical evidence.

Two new triterpene glycosides, a diglycoside (as the corresponding methyl ester) and a bisdesmoside were isolated from leaves of Ilex cornuta.Their structures, termed as ilexside I methyl ester and ilexside II, have been established to be 3β-O-2)-α-L-arabinopyranosyl>-pomolic acid methyl ester and 3β-O-2)-α-L-arabinopyranosyl>-pomolic acid-(28->1)-β-D-glucopyranosyl ester, respectively, based on chemical and spectral evidence, but notably on novel and efficient application of high resolution 1H NMR spectroscopy. - Key Word Index: Ilex cornuta; Aquifoliaceae; two triterpene glycosides; pomolic acid; ilexside I methyl ester; ilexside II.
