  • Title: Identification and determination of tele-methylhistamine in cerebrospinal fluid by gas chromatography-mass spectrometry.
    Author: Swahn CH, Sedvall G.
    Journal: J Neurochem; 1981 Aug; 37(2):461-6. PubMed ID: 7264669.
    Abstract:
    The presence of tele-methylhistamine in human cerebrospinal fluid has been established. The concentration was determined with the use of deuterated tele-methylhistamine. The preparation of the deuterated standard is described. The concentration range in samples from neuropsychiatric patients was 0.1--2.5 ng/ml. The structure of the pentafluoropropionyl derivative used for gas chromatography was studied with the aid of proton nuclear magnetic resonance spectroscopy.
