- Triterpene glycosides from the roots of Sanguisorba officinalis
-
Five triterpene glycosides were isolated from the MeOH extract of Sanguisorba officinalis (Rosaceae) roots, as confirmed by detailed analysis of their 1H, 13C, and two-dimensional NMR data, and by the results of hydrolytic cleavage.

- TWO TRITERPENOID GLYCOSIDES FROM LEAVES OF ILEX CORNUTA
-
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.
