Two new triterpenoid saponins from the root of Ilex pubescens.
Two new triterpenoid saponins, named ilexsaponins B(4) (1) and C (2), have been isolated from the roots of Ilex pubescens. Their structures have been established as ilexgenin B 3-O-alpha-L-arabinopyranosyl-(2-->1)-beta-D-glucopyranosyl-(2-->1)-beta-D-xylopyranoside (1) and 3-O-beta-D-xylopyranosyl spathodic acid 28-beta-D-glucopyranosyl ester (2) by means of spectral and chemical methods.
