[ES]: Se realiza una revisión bibliográfica de la composición lipídica de dos peces pertenecientes al orden PERCIFORMES, familia Gempylidae, Ruvettus pretiosus y Lepidocybium flavobrunneum. La fracción lipídica está compuesta principalmente por esteres tipo ceras (formados por la unión de ácidos grasos y alcoholes grasos median-te enlace tipo éster), además de fosfolípidos, triglicéridos, hidrocarburos y esteróles. Las grasas extraídas de estos peces son utilizadas tradicionalmente por sus propiedades purgantes en pueblos pescadores de islas como Canarias. En los mercados japoneses, estos peces se pueden encontrar como susti-tuto fraudulento de otros peces comestibles. Parece ser que las propiedades tóxico-laxantes son debidas a la gran cantidad de ceras presentes en su fracción lipídica.
[EN]: A review is made on the literature conceming the lipid composition of two fish belonging to PERCIFORMES order, Gempy//c/ae family, Ruvettus pre-tiosus and Lepidocybium fiavobrunneum. The lipid fraction is principally composed of wax esters (esters of fatty acid with long chain fatty alcohols), as well as phospholipids, triglycerides, hidrocarbons and sterols. The lipid extracted from these fish is tradicionally used in consideration of its purgative properties in fishing villages from islands like Canarias. In Japa-nese markets, this fish can be found as a fraudulent substitue of other edi-ble fish. It seems that the toxic-laxative properties are due to the large amount of wax esters in its lipid fraction.
