From the Japanese horse chestnut Aesculus turbinata Blume. 70% triterpene saponin compounds were extracted from 70% ethanol extracts of seeds, and the structures of 2 compounds were identified by spectroscopic analysis. They were: Aescin Ia: 21β-crotonoyl-22a-acetogen 7 Saponins-3β-O-[β-D-glucopyranosyl (1-2)] [β-D-glucopyranosyl (1-4)]-β-D-glucuronopyranoic acid ( 21β-tigloyl-22α-acetylprotoaescigenin-3β-O-[β-D-glucopyranosyl(1-2)][β-D-glucopyra-nosyl(1-4)]-β-D-glucopyra-nosiduronic acid) and seven Leaf saponin Ib: 21β-angelica-22α-acetylsapogenin-3β-O-[β-D-glucopyranosyl (1-2)] [β-D-glucopyranosyl (1 -4)]-β-D-glucopyranoside Glucuronic acid (21β-an-gelovl-22a-acetylprotoaescigenin-3β-O-[β-D-gluconyranosyl(1-2)][β-D-glucopyranosyl(l-4)]-β-D-glucopyranosiduronic acid ), all from the Japanese Aesculus for the first time
