建立了一个用原子吸收光谱法间接测定微量金雀花碱的新体系。依据是,在水相中质子化的金雀花碱与无机络阴离子Zn(SCN)_4~(2-)形成离子对,用有机溶剂1,2-二氯乙烷萃取离子对,于有机相中用火焰原子吸收光谱法测定Zn,以间接测定金雀花碱的含量。确立了测定金雀花碱的最佳实验条件,并成功地测定了健康人血清中微量金雀花碱的含量,检出限为0.027ppm,变异系数为2.3％。 A new system for the indirect determination of trace cytisine by atomic absorption spectrometry was established. Based on the fact that the protonated chrysin in the aqueous phase forms an ion pair with the inorganic complex anion Zn (SCN) _4 ~ (2-), the ion pair is extracted with an organic solvent, 1,2-dichloroethane, Determination of Zn by Flame Atomic Absorption Spectrometry to Indirectly Measure the Content of. The optimal conditions for the determination of cytisine were established. The content of microgasterine in healthy human serum was successfully determined. The detection limit was 0.027ppm and the coefficient of variation was 2.3%.
