Abstract LSD (diethylamide of d-lysergic acid) can be detected by its fluorescence under ultraviolet light and by the production of a deep blue color when it is treated with a solution of p-dimethylaminobenzaldehyde and ferric chloride in sulfuric acid. LSD in an acid aqueous system has a peak maximum at about 312 m/j. This paper describes methods, adapted and modified in our laboratories, which are based on the above chemical properties of LSD. The methods include separatory funnel and column cleanup procedures, fluorescence tests, thin layer chromatography, separation of iso-LSD from LSD, and infrared identification

ABSTRACT Rat and bovine brain have been incubated with testosterone-4-14C under standard conditions. With use of paper chromatography, the extracted metabolites were noted to fall into less-polar, iso-polar, and more polar fractions. The components of the less-polar fraction were separated by acetylation and thin-layer chromatography and the major end-products identified by recrystallization to constant specific activity or constant 3H/14C ratios. Androst-4-enedione and 5α-dihydrotestosterone were formed consistently under the conditions utilized. Trace amounts of other less-polar metabolites were noted occasionally.
