Two New Triterpenoid Saponins from the Seeds of Aesculus chinensis
摘要:
Two new triterpenoid saponins, named isoescins IIIa (1) and IIIb (2) were isolated from the seeds of Aesculus chinensis and identified by spectroscopic analysis and chemical hydrolysis.Their structures were established as 21b-tigloyl-28-acetylbarringtogenol C-3β-O-[b-D-galactopyranosyl (1→2)] [β-D-glucopyranosyl (1→4)]-β-D-glucopyranosiduronic acid (1) and 21β-angeloyl-28-acetylbarringtogenol C-3β-O-[β-D-galactopyranosyl (1→2)] [b-D-glucopyrano-syl (1→4)]-β-D-glucopyranosiduronic acid (2), which are geometrically isomeric.
