摘　　要：A pair of novel geometrically isomeric triterpenoid saponins named escins IVa and IVb, together with known escins Ia and Ib. were isolated from the seeds of Aesculus chinensis. Their structures were determined on the basis of spectroscopic evidences and comparison.A pair of novel geometrically isomeric triterpenoid saponins named escins IVa and IVb, together with known escins Ia and Ib. were isolated from the seeds of Aesculus chinensis.
