title: A cytotoxic saponin from Albizia julibrissin.
abstract: A new triterpenoidal saponin (1: Julibroside J(21)) with a xylopyranosyl moiety located at its C-21 side chain was isolated from Albizia julibrissin DURAZZ. (Leguminosae), and its structure was determined on the basis of comprehensive spectroscopic analyses. Compound 1 showed marked inhibitory action against Bel-7402 cancer cell line at 10 microg/ml.
