摘 要:Three new triterpenoid saponins, escins IVc (1), IVd (2) and IVf (3) were isolated from the seeds of Aesculus chinensis. They were. determined as 22 alpha-tigloyl-28-acetylprotoaescigenin-3 beta-O- [beta-D-glucopyranosyl (1--2)] [beta-D-glucopyranosyl (1--4)]-beta-D-glucopyranosiduronic acid 1, 22 alpha-angeloyl-28-acetylprotoaescigenin-3 beta-O- [beta-D-glucopyranosyl (1--2)] [beta-D-glucopyrano- syl (1--4)]-beta-D-glucopyranosiduronic acid 2 and 28-tigloyl protoaescigenin-3 beta-O- [beta-D-gluco-pyranosyl (12)] [beta-D-glucopyranosyl (1--4)] -beta-D-glucopyranosiduronic acid 3.
