摘要
建立血浆样品中葛根素的薄层-紫外光密度扫描法。采用日本岛津CS-91O型双波长薄层扫描仪;高效硅胶G板;乙酸乙酯:甲醇:H_2O::甲苯:无水乙醇(10O:15.5:13.5:2:13.5V/V)为展开剂。最小检测量为7.5ng/点。不同板间测定精密度(CV)为8.4％～13.8%,板内精密度为6.7%,同点重复扫描精密度为4.2%。家兔vi 30mg/kg的药时曲线经计算机非线性最小二乘法拟合为开放式二室模型,其T_(1/2)α、T_(1/2)β分别为5.7min,27.5min。
A simple thin layer chromatography ultraviolet densitometric method has been established for the separation and quantitative determination of Puerarin in plasma. Using ethyl acetate : metha-nol: water : toluene : absolute alcohol ( 100 : 15.5: 13.5: 2 :13.5 V/V ) as the developing system, 5μl supernatant of the sample extracts were spotted on high performance sillica gel G glass plates and developed. The separeted spots were scanned using Shimadzu CS-910 TLC scanner, the results were calculated by the areas...
