Identification and determination of tele-methylhistamine in cerebrospinal fluid by gas chromatography-mass spectrometry

C H Swahn et al. J Neurochem. 1981 Aug.

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.
