Four new triterpenoid estersaponins, tentatively designated as IIIA(2) (1), IIIA(3) (2), 111132 (3), and IIIC4 (4) have been isolated from fruits of Pittosporum tobira AIT. and their structures elucidated by spectroscopic and chemical analyses. All the four compounds consist of an acylated pentacyclic triterpenoid aglycone which bears the same oligosaccharide portion. The crude saponin mixture (CIDI) was found to show significant in vitro and in vivo cytotoxicity in different human cancer cell lines. (C) 2002 Elsevier Science Ltd. All rights reserved.
