Abstract

Six diterpenes among which two new (8beta-hydroxy-9(11),13-abietadien-12-one and 5,6-didehydroferruginol) were isolated from the seeds of Cephalotaxus harringtonia. The compounds were studied for their antimicrobial activity in vitro against clinically isolated bacteria and Candida strains. Ferruginol and 6,12-dihydroxyabieta-5,8,11,13-tetraen-7-one showed antimicrobial activity against Gram-positive bacteria. None of the six diterpenes was active against the Gram-negative organisms and yeasts tested.
