Three azulenoid sesquiterpenes (1 – 3) were isolated from the Antarctic gorgonian Acanthogorgia laxa collected by bottom trawls at 343 m. Besides linderazulene (1), and the known ketolactone 2, a new brominated C16 linderazulene derivative (3) was also identified. This compound has an extra carbon a...
