Bioactive Saponins and Glycosides. XII. Horse Chestnut. (2): Structures of Escins IIIb, IV, V, and VI and Isoescins Ia, Ib, and V, Acylated Polyhydroxyoleanene Triterpene Oligoglycosides, from the Seeds of Horse Chestnut Tree (Aesculus hippocastanum L., Hippocastanaceae).

New acylated polyhydroxyoleanene triterpene oligoglycosides, escins IIIb, IV, V, and VI and isoescins Ia, Ib, and V, were isolated from the seeds of horse chestnut tree (Aesculus hippocastanum L.). Their structures were elucidated on the basis of chemical and physicochemical evidence.
