title: Diastereoisomeric saponins from Albizia julibrissin.
abstract: The structures of four new diastereoisomeric triterpenoidal saponins Julibroside J5, J8, J12 and J13 (1-4) isolated from Albizia julibrissin Durazz. (Leguminosae) have been determined on the basis of comprehensive spectroscopic analysis and chemical degradation. Julibroside, J8 and J13 showed marked cytotoxic activities against Bel-7402 cancer cell line at 100 microg/mL.
