The results manifest that the concentration of glycocholic acid has satisfactory linear correlation whith peak area, regression equation: Y= 39579X + 57823,R2=0.9984;The lowest detected concentration is 0.02μg/mL with S/N=3 ; Average recovery rate is 98.49%; RSD为0.52%～2.00%in day, RSD为0.74%～4.98%between days;The average recovery rate is 99.35%, RSD is 2.24% in the first team, and it is 100.87%, RSD is 4.73% in the second team at the stability test. When the concentration of glycocholic acid was detected in the liver, kidney and brain tissue, corresponding tissue concentration was calculated by preparing the standard curve with the glycocholic acid standard preparation in vitro, but the result can only reflect the relative chang law of the concentration of glycocholic acid in tissue but not in real tissue. The result of tissue stability experiment is consistent with that of the serum experiment.

结果表明，在0.15625～10.0μg/ml范围内血清中甘氨胆酸浓度与峰面积呈良好的线性关系，回归方程Y= 39579X + 57823，R2=0.9984；以信噪比S/N=3为标准，最低检测浓度为0.02μg/ml；平均回收率为98.49%；日内RSD为0.52%～2.00%，日间RSD为0.74%～4.98%；稳定性试验第一组的平均含量为99.35%，RSD为2.24%，第二组的平均含量为100.87%，RSD为4.73%；测定了肝、肾、脑组织中甘氨胆酸含量，采用体外甘氨胆酸标准品制备标准曲线的方法计算了相应的组织浓度，其结果仅反映组织中甘氨胆酸浓度的相对变化规律，不能体现真正的组织浓度值，但对组织样品的稳定性进行了较细致的考察，其结果和血样结果基本一致。
