【摘要】：建立了非水电位滴定测定甘油磷脂酰胆碱(GPC)含量的方法。采用高氯酸标准溶液对GPC样品进行电位滴定,利用二级微商法确定电位滴定终点消耗的高氯酸标准溶液体积从而得出GPC含量,用建立的方法测得自制GPC样品含量为78.73%,其方法精密度RSD为0.048%。该法操作方便、准确度高,适合GPC的快速检测。
[Abstract]:A method for the determination of glycerophosphatidylcholine (GPC) by non-hydroelectricity potentiometric titration was established. Perchloric acid standard solution was used for potentiometric titration of GPC samples. The volume of perchloric acid standard solution consumed at the end point of potentiometric titration was determined by the two-order microquotient method and the GPC content was obtained. The content of self-made GPC sample was 78.733.The precision RSD of the method was 0.048. The method is easy to operate and has high accuracy. Suitable for rapid detection of GPC.
