    Abstract

    1. A general method of estimation of alicyclic and aliphatic amines in plasma, whole blood, urine and tissue with specific reference to cocaine and mescaline has been described.

    2. The importance of the type of shaking for extraction of amines from biological material has been discussed.

    3. The procedure for mescaline and cocaine has been shown to be specific.

    4. Only halogenated sulfonephthalein dyes may be used for color development which is apparently dependent upon quininoid formation from the dye.

    5. Investigation of numerous amines indicates that the method has wide application and that color formation is inversely proportional to the molecular weight of the amine.

    6. Chloroform appears to be the most convenient solvent to use although preliminary experiments indicate that methylene dichloride, methylchloroform, anisole, bromobenzene, chlorobenzene, toluene and benzene might be employed depending upon the amine, etc.
