Alkaloids are widely present in food and medicine. However, many alkaloids have poisoning effect. Thus, a sensitive and rapid method for determination of alkaloids is highly desired. In this study, a convenient, reliable and accurate method is developed for the simultaneous determination of 16 poisonous alkaloids in human blood by ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) coupled with supported liquid extraction (SLE). The 16 alkaloids include colchicine, anisodamine, scopolamine, atropine, sinomenine, dicaine, thebaine, papaverine, strychnine, brucine, aconitine, hypaconitine, yunaconitine, deoxyaconitine, bullatine A and bullatine B. Low limits of detection (LODs) were obtained ranging in 0.002-0.03 μg L-1. The linear ranges are 0.005-200 μg L-1 for colchicine, papaverine, brucine, aconitine, hypaconitine, yunaconitine and deoxyaconitine, 0.01-200 μg L-1 for anisodamine and scopolamine, 0.05-200 μg L-1 for atropine, strychnine, bullatine A and bullatine B, 0. 1-200 μg L-1 for other target analytes, all with correlation coefficients (R2) higher than 0.995. The recoveries range from 79.2% to 95.8%. The relative standard deviation (RSD) values are lower than 15% and the values of matrix effect (ME) range in 86.3%-118.2%. This method of UPLC-MS/MS coupled with SLE has high potential for analyzing multiple alkaloids in blood samples.

D053719 Tandem Mass Spectrometry A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
