title: [Inositol-containing phospholipids in rat brain and liver].
abstract: A simple modification of the method of Rossiter and Palmer for the quantitative determination of phosphoinositides (PI) in animal tissues (brain and liver) is worked out: Phospholipids are mineralyzed (together with a paper) in 57% perchloric acid, avoiding the time consuming procedure of the tenfold elution of inositids spots from chromatogramms and the subsequent evaporation of the substantial volume of the eluate obtained. The time of the analysis is twice as short as that of the original method, the data obtained being reliable. The quantity of mono-, di- and triphosphoinositides in rat brain is as follows: 85.08, 11.33 and 32.85 mkg P/g wet tissue, but in liver it is 94.5, 1.88 and 2.5 mkg P/g wet tissue respectively.
