A bioassay‐guided fractionation of Juniperus procera berries yielded antiparasitic, nematicidal and antifouling constituents, including a wide range of known abietane, pimarane and labdane diterpenes. Among these, abieta‐7,13‐diene (1) demonstrated in vitro antimalarial activity against Plasmodium falciparum D6 and W2 strains (IC 50 = 1.9 and 2.0 µg/mL, respectively), while totarol (6), ferruginol (7) and 7 β ‐hydroxyabieta‐8,13‐diene‐11,12‐dione (8) inhibited Leishmania donovani promastigotes with IC 50 values of 3.5–4.6 µg/mL. In addition, totarol demonstrated nematicidal and antifouling activities against Caenorhabditis elegans and Artemia salina at a concentration of 80 µg/mL and 1 µg/mL, respectively. The resinous exudate of J. virginiana afforded known antibacterial E ‐communic acid (4) and 4‐ epi ‐abietic acid (5), while the volatile oil from its trunk wood revealed large quantities of cedrol (9). Using GC/MS, the two known abietanes totarol (6) and ferruginol (7) were identified from the berries of J. procera , J. excelsa and J. phoenicea . Copyright © 2008 John Wiley & Sons, Ltd.
