 Title    Isolation and Characterization of Cytotoxic Diterpenoid Isomers from Propolis  
 Abstract    The methanol extract of Brazilian propolis was frac­ tionated by HPLC, based on HuH13 (human hepatocel­ lular carcinoma) cell cytotoxicity assay. Two isomers of diterpenoid with a molecular formula of C20H 30O 3 (MW: 318.46) were isolated. The structures of these colorless compounds were determined as clerodane diterpenoids (I, 15-oxo-3, 13Z-kolavadien-17-oic acid; II, 15-oxo-3Z, ISf-kolavadien-n-oic acid).
