摘要：

Two new halogenated sesquiterpenes, (8 beta) 10 bromo-3-chloro-2,7-epoxychamigr-9-en-8-ol (1) and 2 bromo-3 chlorobisabola-7(14),11 diene 6,10 diol (3). and one new phytol derived diterpene, epoxyphytyl acetate (4), along with cis- and trans 1-methylcyclohexane-1,4-diol (5 and 6) which were isolated from a natural source for the first time but have been previously synthesized were isolated from the marine red alga Laurencia composita and characterized In addition, a known sesquiterpene, pacifenediol (2), and the known furanone derivative 7 were also identified Their structures were established by MAR and mass spectroscopic methods.
