We have developed a procedure for the accurate measurement of histidine decarboxylase in tissues expressing low levels of enzymatic activity. Briefly, histamine is enzymatically synthesized from [ 3 H]-labeled histidine, followed by purification using high-performance liquid chromatography (HPLC) an
The quantitative determination of morphine in paregoric by reversed-phase high-pressure liquid chromatography is described. The method is simple, accurate, and fast compared to the USP method. Benzoic acid in paregoric also can be determined quantitatively with the same column. The method was applie
