The distribution of lipids and photosynthetic pigments (PSP) in the different zones of blade as apical, middle and intercalary meristem, as well as in the stipe with rhizoids two species Saccharina of Japan sea: Saccharina cichorioides (Miyabe)andS. angustata (Kjellman) with tallus blade –like and two digitate species: S. dentigera(Kjellman)и S. bongardiana (Postels et Ruprecht) from Okhotsk sea were investigated. Variation in lipid content  and PSP in zones of blade of S. cichorioides  with starting of growth and it termination were investigated additionally. Significant differences in the distribution of total lipids (TL), their individual classes, fatty acids (FA) and PSP in different zones of the thallus were founded, which had the species peculiarities and determined by the conditions habitat and the stage of development of algae rather than the morphology of the thallus.In algae S. cichorioides grow up completed, in contrast to algae started of growth, there was an increase in lipid content in all parts of the blade, but in the stipe with rhizoids lipid content was reduced. Along with this, there was a redistribution contents all classes of lipids and PSP, saturated (SFA) and unsaturated (USFA) FA in zones of the blade: the content of first decreases sharply in the apical part and in the middle of the blade, but USFA - increased. Such restructuring is likely to have been associated with the beginning of stage of sporogenesis.
