A Latrunculia sp. collected off Port Phillip Bay, Victoria, returned three new norsesterterpene cyclic peroxides. Trunculins G (9), H (10) and I (11) were isolated as their methyl esters (12), (13) (14) respectively. Gross structures for these trunculins assigned on the basis of spectroscopic analysis, while absolute stereochemistry about peroxide terminus was established by application Horeau Mosher procedures.
