title: Cytotoxic cycloartanes from Aglaia argentea.
abstract: Aglaia argentea leaves yielded three new cycloartanes: argenteanones A and B, and argenteanol. The first two possess cytotoxic activity against KB cells (IC50 7.5 micrograms ml-1 and 6.5 micrograms ml-1 respectively). Structural elucidation was done by two-dimensional NMR spectroscopy.
