title: Antimicrobial diterpenes of Croton sonderianus, 1. Hardwickic and 3,4-secotrachylobanoic acids.
abstract: The hexane-extracted resin of the roots of Croton sonderianus showed antimicrobial activity in standardized bioassays. Fractionation of the resin yielded two acid diterpenes, (-)-hardwickic acid [2] and the new 3,4-secotrachylobanoic acid [5] as major bioactive materials.
