Abstract

Abstract: Aim To study the saponin constituents of the seeds of Aesculus chinensis Bunge var. chekiangensis (Hu et Fang) Fang. Methods Compounds were separated and purified by macroreticular resin column chromatography and high-performance liquid chromatography. Their structures were elucidated by spectroscopic and hydrolysis analysis. Results Six compounds were isolated from the 70% ethanolic extracts. They were identified as escins IVc, IVd, Ia, Ib, isoescins Ia and Ib, respectively. Conclusion The above compounds were obtained from the seeds of Aesculus chinensis Bunge var. chekiangensis (Hu et Fang) Fang for the first time.

Key words: Aesculus chinensis Bunge var chekiangensis, Aesculus chinensis Bunge var chekiangensis, triterpenoids, triterpenoids, escin, escin, isoescin, isoescin
