Abstract
建立大鼠不同组织(脑、心、肺、肝、脾、小肠、肾、脂肪和肌肉)中s-油酰丙醇胺含量的测定方法,并研究s-油酰丙醇胺在大鼠体内的组织分布情况。s-油酰丙醇胺提取采用液-液萃取,以10-十一烯酰乙醇胺为内标。SD雄性大鼠灌胃给予s-油酰丙醇胺(50 mg.kg-1)后,于4个时间点(各时间点5只大鼠)处死大鼠后,取相应组织匀浆处理,通过LC-MS/MS法测定其各脏器或组织中浓度。通过多反应检测模式测得定量下限1μg.L-1,各组织匀浆中s-油酰丙醇胺在1~2×104μg.L-1内线性良好(r≥0.999 0),方法经验证符合生物样品分析要求。灌胃给药后药物浓度最高的组织为小肠和心脏,达峰时间分别为15和90 min。该法操作简便、灵敏度高,适用于s-油酰丙醇胺在大鼠体内的组织分布研究
