【摘要】:建立了超高效液相色譜-三重四極桿-線性離子阱質譜(Qtrap-UPLC-MS/MS)法同時測定大鼠腦組織中4種氨基酸類神經(jīng)遞質,研究了礦物藥青礞石原藥材粉末、水煎液、藥渣對戊四氮(Pentylenetetrazol,PTZ)點燃癲癇模型大鼠腦組織中氨基酸類神經(jīng)遞質含量的影響。在ESI+電離模式下,采用多反應監(jiān)測掃描方式測定腦組織(皮層,海馬)中谷氨酸(Glu)、甘氨酸(Gly)、天冬氨酸(Asp)及γ-氨基丁酸(GABA)的含量。結果表明:4種氨基酸的線性關系良好,精密度、準確度均符合生物樣品的分析要求。大鼠給予青礞石不同樣品后,腦組織皮層和海馬中興奮性神經(jīng)遞質Glu、Asp水平顯著降低。與模型組相比,皮層中Gly占氨基酸總含量的百分比均增加,Asp/Gly值、Glu/Gly值均降低;海馬中,各組Glu、Asp、Gly、GABA的濃度均降低。這說明,礦物藥青礞石能有效降低PTZ點燃大鼠腦內興奮性氨基酸遞質含量,調節(jié)皮層和海馬區(qū)Gly含量。
[Abstract]:A high performance liquid chromatography-triple quadrupole linear ion trap mass spectrometry (Qtrap-UPLC-MS / MS) method was developed for simultaneous determination of four amino acid neurotransmitters in rat brain. In this paper, we studied the effect of the mineral drug, protophore powder, decoction and residue on pentylenetetrazol (Pentylenetetrazol) in pentylenetetrazol (PTZ). The effect of amino acid neurotransmitters in brain tissue of kindled epileptic rats was studied. Under ESI ionization mode, the brain tissue (cortex) was measured by multi-reaction monitoring scanning. The contents of glutamate, glycine, aspartic acid and GABA in hippocampus showed a good linear relationship and precision. The level of excitatory neurotransmitter Gluus Asp in cerebral cortex and hippocampus of rats was significantly lower than that of model group. The percentage of Gly in total amino acid content in cortex increased and the value of Asp-gly decreased. In the hippocampus, the concentration of Glu-AspGlyGA-GABA in each group was decreased, which indicated that the mineral penicillin could effectively reduce the content of excitatory amino acid transmitters in the brain of PTZ kindled rats. To regulate the content of Gly in cortex and hippocampus.
