A pre-column derivatization-high performance liquid chromatographic (HPLC) method has been developed for the determination of histamine in canned fish. The homogenated samples were ultrasonically extracted with perchloric acid aqueous solution, derivatized with dansyl chloride and diluted with acetonitrile to a desired volume. The samples were determined by HPLC with ultraviolet detector and quantified by external standard method. Adopting a C18 column with 1.8 microm stationary phase particles, the analysis time for each sample was smaller than 5 min with the flow rate of 0.3 mL/min. It can decrease the consumption of the mobile phase and save the cost. The linear range was 0.08-8.00 mg/L for histamine. The correlation coefficient was 0.999 98. The average recoveries of histamine at different concentration levels in spiked samples were greater than 96% and the relative standard deviations (RSDs) were smaller than 2.5%. The quantitation limit was 5.00 mg/kg for histamine in canned fish by HPLC. The results indicated that this HPLC method is fast, sensitive, reproducible and practical for the routine analysis of histamine in canned fish.

    ABSTRACT: Herbal medicines have ever been thought harmless, but it is obviously not true. Many adverse reports emerged with the development of their popular application in the world. Allergic reactions, especially serious immediate hypersensitivity, frequently occurred when herbal injections were used in clinic and made this ever prevailing agent nearly disappear in China. The aim of this study is to establish a rapid and economical method for the prediction of the allergenicity of herbal injections. Ovalbumin (OVA) and four other herbal injections, in which two of them were well known for their allergenicity, were selected to sensitize and stimulate the animals. Serotonin in the animal serum was detected with HPLC to reflect the anaphylactic response and compared with the other cytokines which could mediate the anaphylaxis, including histamine, IgE and β-hexosaminidase. The results suggest that serotonin can be detected quickly and has good correlation with the other allergy-related cytokines. It is a promising way for predicting the allergenicity of the herbal injections and those complicated natural products.
