[A comparative evaluation of methods for the isolation of khlozepid from human cadaveric liver]. / Sravnitel'naia otsenka metodov izolirovaniia khlozepida iz pecheni trupa cheloveka.

Comparative evaluation of two isolation methods in fatal chlozepid poisoning was performed using expert material. Isolation by neutral acetone from visceral tissues showed that chlozepid and its metabolites are extracted in amounts 6-13 times greater (in terms of chlozepid) than using A. A. Vasil'eva's method. Quantitative determination was performed by photometry according to the reaction of azo dye formation after hydrochloric acid hydrolysis of the extracts.
