A drimane, (+)-drimenol (1), five known herbertanes, (−)-α-herbertenol (2), (−)-herbertenediol (3), mastigophorene A (4), (−)-mastigophorene C (5) and (−)-mastigophorene D (6), a pimarane, (−)-e nt-pimara-8(14),15-dien-19-oic acid (7), and two eudesmanolides, (−)-diplophyllolide A (8) and (−)-diplophyllin (9) were isolated from the Tahitian Mastigophora diclados (Brid.) Nees. Herbertane sesquiterpenes (2, 3, 5 and 6) showed cytotoxicity against HL-60 and KB cell lines, radical scavenging activity and antimicrobial activity against Bacillus subtilis. (−)-Diplophyllolide A (8) also exhibited cytotoxicity against HL-60 and KB cell lines.
