摘要
目的: 测定壮骨关节丸中补骨脂素、异补骨脂素的含量。方法: 高效液相色谱法, AlltimaC18 分析柱(250 m m ×4-6 m m , 5 μm) , 流动相: 甲醇- 水(50∶50) , 检测波长: 245 nm , 流速:1-0 mL·min - 1 , 柱温: 40 ℃。结果: 补骨脂素在0-074 8 ~0-598 4 μg (r = 0-999 9) 、异补骨脂素在0-075 4 ~0-603 2 μg (r = 0-999 9) 范围内呈线性; 补骨脂素和异补骨脂素平均回收率分别为98-28 % ( RSD= 1-6 % ) 和98-72 % ( RSD= 2-0 % ) 。结论: 本方法简便、快速, 准确。
Objective:To determine psoralen and isopsoralen in Zhuanggu Guanjie pills Methods:The chromatographic conditions included Alltima C 18 column(250 mm×4 6 mm,5 μm)and the mobile phase consisting of a mixture of methanol-water(50∶50) Detection wavelength was at 245 nm.The flow rate was 1 0 mL·min -1 . Column temperature was at 40 ℃. Results:The calibration curve of psoralen was 0 074 8~0 598 4 μg( r=0 999 9 ). The calibration curve of isopsoralen was 0 075 4~0 603 2 μg( r=0 999 9) . The average recovery of psoralen and isopsoralen were 98 28% ( RSD=1 6 %) and 98 72% ( RSD=2 0 %) respectively. Conclustion: The method is simple and accurate.
