The Fucales plants have very homogenous taxonomic characteristics at order level, but show many morphological variations at species or subspecies levels. This study is one of the serial works to obtain more taxonomic data than morphotaxonomic ones and to clarify the taxonomic ranks and characteristics of Korean Fucales plants through physiological and biochemical analyses. Total lipid compositions of Korean Fucales plants were analyzed by the 3-dimensional TLC method. Major components of phospholipids (PA, PC, PG, PE, DPG, LPE, LPC), neutral fat TG and sterols were commonly contained in each species. Unknown lipids X1, X2 and X3 were contained in genus Sargassum, but Hizikia was lacking X3 and Myagropsis was lacking both X2 and X3. The latter contained unique X8. From the view-point of the phylogeny of lipid metabolism, Sargassum might be more closely related to Hizikia than to Myagropsis. A variant of S. patens from Seongsan showed minute metabolic difference from that of the typical plant; but a variant of S. serratifolium did not show any significant difference from that of the typical plant
