✦ Synopsis

lnst4tzctc fov Reseamh, Prod~wtion a,nd Apfilicatio~ of Radioisotopes,' Z-Vague (Czccl~oslovakia.) (Rcccivccl Scptxmber zest, 1971) SUIMMAIIY Fatty acids of the alga Clzloralla vzdgari~ ($yrenoidosn) were analyzed by the gas-liquid chromatography of their methyl esters.' By use of two (polar and nonpolar) stationary phases, comparison with standards and bromination CIQ-CBO fatty acids were detected and identifred. In addition to the major acicls (palmitic, oleic, linoleic and linolenic) the alga lipids contain 32-14: o, 14: I, 14: z, 14: 3, gz-15 : o, U&IS; o, 1G:1, 16 : 2, 16 : 3, 12-17 : 0, ai-: 0, 9~18: o, PZ-KJ,: o and ~20: o fatty acids at levels in excess of 0.1 %.. The. results obtained are of importance in the analytical control of the radiochemical purity of I%-labelled higher fatty acids prepared from the alga, The presence of odd (straight-chain and branched) acids is interesting from biochemical viewpoint,
