Eight lipid patterns of Salicornia seed oil have been elucidated using HPLC as the main tool of analysis in conjunction with capillary GLC. The whole oil is rich in linoleic (66.5%) with lower amount of linolenic acid (1.4%). Of the 22 triglycerides (TG) determined, three major TG containing 3 and 2 linoleic acyls were detected by HPLC. The total tocopherols content (720 ppm) was determined directly in the oil by HPLC and it was found that alpha-T (49.1%) and gamma-T (48.2%) are predominating.<br />The whole sterol profile, as determined by GLC, includes cholesterol (1.0%), brassicasterol (1.4%), campesterol (2.4%), 5-stigmasterol (8.7%), beta-sitosterol (23.0%), spinasterol (17.0%), isofucosterol (0.8%), 7-stigmastenol (42.0%) and 7-avenasterol (3.7%). Furthermore, sterols patterns of the free (nonacylated) sterols (FS), acylated sterols (AS), free sterylglycosides (FSG) and acylated sterylglycosides (ASG) were determined by HPLC as their anthroylnitriles. FS and AS were determined as their steryl-9-anthroylnitriles (S-9-AN) whereas FSG and ASG were analysed as their sterylglycosidyl-1-anthroylnitriles (SG-1-AN) at nanogram level. <br /> Comparing Salicornia SOS-7 oil with traditional freshwater seed oils, Salicornia exhibits mostly a unique lipids constitution.<br><br>Se han dilucidado ocho perfiles lipídicos de aceite de semilla de Salicornia usando HPLC como principal herramienta de análisis junto con la CGL capilar. El aceite completo es rico en linoleico (66.5%) con bajo contenido en ácido linolénico (1.4%). De los 22 triglicéridos (TG) determinados, los tres mayoritarios que contenían 3 y 2 cadenas de linoleico se detectaron por HPLC. El contenido en tocoferoles totales (720 ppm) se determinó directamente en el aceite por HPLC y se encontró al alfa-T (49.1%) y al gamma-T (48.2%) como predominantes. El perfil de esteroles completo, determinado por CGL, incluyó colesterol (1.0%), brasicasterol (1.4%), campesterol (2.4%), 5-estigmasterol (8.7%), beta-sitosterol (23.0%), espinasterol (17.0%), isofucosterol (0.8%), 7-estigmastenol (42.0%) y 7-avenasterol (3.7%).<br /> Además, los perfiles de esteroles de los esteroles libres (sin acilar) (FS), esteroles adiados (AS), esterilglicósidos libres (FSG) y esterilglicósidos acilados (ASG) se determinaron por HPLC como sus antroilnitrilos. FS y AS se determinaron como sus esteril-9-antroilnitrilos (S-9-AN) mientras que FSG y ASG se analizaron como sus esterilglicosidil-1-antroilnitrilos (SG-1-AN) a niveles de nanogramos. <br /> Comparando el aceite de Salicornia SOS-7 con los aceites de semillas de agua dulce tradicionales, el de Salicornia mostró principalmente una constitución lipídica característica
