The dichloromethane extract of leaves of Croton zambesicus (Euphorbiaceae)
showing in vitro cytotoxicity against human cervix carcinoma cells was
investigated in order to identify its active compounds. A bio-guided
fractionation by HSCCC followed by MPLC led us to isolate a trachylobane
diterpene, ent-trachyloban-3beta-ol, with cytotoxic properties (IC50 on HeLa
cells = 7.3 microg/ml). This is the first report on the cytotoxicity of a
trachylobane diterpene.
