A rapid method of isolating a phenothiazine derivatives from cadaveric specimens

Proximate method for isolation of 10 psychotropic compounds of phenothiazine series from the cadaveric material was developed using acetonitrile with subsequent extraction of these derivatives by ether at pH 13.0 and reextraction by 0.5 n. solution of sulfuric acid. Method of isolation by acetonitrile shortens time for analysis by 5-6 times as compared with modified Stas-Otto method suggested previously for this purpose.
