title: Bioactive saponins and glycosides. XVIII. Nortriterpene and triterpene oligoglycosides from the fresh leaves of Euptelea polyandra Sieb. et Zucc. (2): Structures of eupteleasaponins VI, VI acetate, VII, VIII, IX, X, XI, and XII.
abstract: Following the elucidation of eupteleasaponins I, II, III, IV, V, and V acetate, eupteleasaponins VI, VI acetate, VII, VIII, IX, X, XI, and XII were isolated from the fresh leaves of Euptelea polyandra Sieb. et Zucc. The structures of eupteleasaponins VI-XII were determined on the basis of chemical and physicochemical evidence.
