Recently, algal biomasses have become interested as a source of food and feed materials. The investigation of the algal constituents, therefore, must be performed in order to utilize effectively red algae. The present paper describes the constituents such as sterol, hydrocarbon and higher fatty acid fractions from the dried red alga porphyra pseudolinearis UEDA growing profusely in the Sea of Japan. Components of the P. Pseudolinearis were extracted with methanol and the extract was examined by combined gaschromatograph-mass spectrometry (GC-MS). The alga is charactesjzed by a higher content of desmosterol [5, 24-cholestadien-3β-ol] (68%) in the sterol fraction and the contents of brassicasterol [(24R)-24-methylcholesta-5, 22-dien-3β-ol] (10%), cholesterol (19%) and fucosterol (or 28-isofucosterol) (3%) were low. cis-7-Heptadecene was characteristically detected in the hydrocarbon fraction. Palmitic acid and methyl palmitate were detected, respectively, as major components in the fatty acid fraction.
