Ten new oleanene-type triterpene oligoglycosides were isolated from Chinese Glycyrrhizae Radix, the dried root of Glycyrrhiza uralensis Fischer [Tohoku-Kanzo (in japanese) from China], and the structures of five olygoglycosides, named licorice-saponins A3 (3), B2 (5), C2 (7), D3 (9), and E2 (12) have been determined on the basis of chemical and physicochemical evidence.
