Extractive and Degradative Procedure (1 16-1 18) With the recognition of the extensive occurrence of amine oxides as alkaloids in the plant there have been developed differential isolation procedures, to separate these from the amines, and reduction procedures, applied to crude extracts, to convert all the amine oxides to amines. For qualitative detection of amine oxides, the red or reddish brown coloration that these compounds give with acetic anhydride serves as a useful test (150). The problem of the separation of the naturally occurring amines from the amine oxides has been attacked in different ways.
