An improved and validated method for the determination of vinpocetine in human plasma using a combination of a solid-phase extraction as a cleaning step followed by gas chromatography-mass spectrometry (GC-MS) has been presented. Quantitation has been carried out with apovincaminic acid methyl ester as internal standard. A limit of detection of 0.01 ng/ml, limit of quantitation of 0.10 ng/ml, as well as a satisfactory accuracy, improved precision and prolonged capillary column life have been achieved.
本文提出了一种改进且经过验证的方法，用于测定人血浆中的长春西汀。该方法采用固相萃取作为净化步骤，随后结合气相色谱 - 质谱联用（GC-MS）。采用阿朴长春胺酸甲酯作为内标进行定量分析。实现了0.01 ng/ml的检测限、0.10 ng/ml的定量限，以及令人满意的准确度、更高的精密度和延长的毛细管柱寿命。
