Two new triterpene saponins, 16-O-acetyl-21-O-angeloyltheasapogenol A 3-O-[beta-D-galactopyranosyl(1 --> 2)][beta-D-xylopyranosyl(1 --> 2)-alpha-L-arabinopyranosyl (1 --> 3)]-beta-D-glucopyranosiduronic acid (1) and 16,28-O-diacetyl-21-O-tigloyltheasapogenol A 3-O-[beta-D-galactopyranosyl(1 --> 2)][beta-D-xylopyranosyl(1 --> 2)-alpha-L-arabinopyranosyl (1 --> 3)]-beta-D-glucopyranosiduronic acid (2), together with four known triterpenenes, have been isolated from the dried seedling of Aronia melanocarpa, and their structures established by spectroscopic and chemical evidence.
