%X Halophyte is an oil seed coded as SOS-7 (Salicomia Oil Seed, 7th year of selection). Tocopherol constituents of SOS-7 halophyte oil were determined directly in the oil by using high pressure liquid chromatography coupled to fluorescence detector. It was found that the oil contains 710 ppm total tocopherols. The tocopherol constituents, alpha, beta, gamma and delta, were found at the level of 38.2,1.0, 58.7 and 2.1% respectively. Nine flavonoid glycosides were isolated and identified from the seeds and it was found that they belong to the flavonol class of flavonoids. These flavonol compounds were identified as: quercetin-3, 7-diglucoside, quercetin-3-glucoside-7-galactoside, quercetin-3-sophoroside, quercetin-3-glucoside, quercetin-3-galactoside, isorhamnetin-3, 7-di-glucoside, isorhamnetin-3-glucoside, kaempferol-3, 7-diglucoside and kaempferol-3-glucoside. Halofito es una semilla oleaginosa codificada como SOS-7 (semilla oleaginosa Salicomia, s谷ptimo a o de selecci車n). Los tocoferoles del aceite de halofito SOS-7 fueron determinados directamente en el aceite usando cromatograf赤a l赤quida de alta presi車n acoplada a detector fluorescente. Se encontr車 que el aceite conten赤a 710 ppm de tocoferoles totales. Los tocoferoles alfa, beta, gamma y delta, se encontraron a niveles de 38.2,1.0, 58.7 y 2.1%, respectivamente. Nueve glic車sidos flavonoides fueron aislados e identificados de las semillas y se encontr車 que pertenecen a la clase flavonol dentro de los flavonoides. Estos flavonoles fueron identificados como: quercetina-3,7-diglucosido, quercetina-3-glucosido-7-galactosido, quercetina-3-soforosido, quercetina- 3-glucosido, quercetina-3-galactosido, isorannetina-3, 7-di-glucosido, isorannetina-3-glucosido, kampferol-3, 7-diglucosido y kampferol-3-glucosido.
