title: Cytotoxic cyclopenta[b]benzofuran derivatives from the stem bark of Aglaia formosana.
abstract: A new cytotoxic cyclopenta[b]benzofuran derivative, aglaiformosanin (1) and three known cyclopenta[b]benzofuran derivatives (2 - 4) were isolated from the stem bark of Aglaia formosana. Compounds 1 - 4 exhibited potent cytotoxicity against the P-388, KB, HT-29, HL-60, and A549 cell lines. The structure of compound 1 was determined by spectroscopic analysis.
