【摘要】 目的测定不同地区地黄饮片中梓醇含量。方法高效液相色谱(HPLC)法,流动相:乙腈-水(0.5∶99.5);检测波长:210 nm。结果标准曲线为:Y=347.93X+10.138(R2=0.999 6),梓醇在0.322 4~2.901 6μg时呈良好的线性关系;平均回收率为96.21%,RSD为1.35%(n=5)。结论该法简便、快捷、准确,不同地区地黄饮片的梓醇含量差异很大。更多还原

【Abstract】 Objective To determine catalpol in processed Radix Rehmanniae products from different areas.MethodsMobile phase: cetonitrile-water(0.5∶99.5),detection wavelength: 210 nm.ResultsStandard curve : Y=347.93X + 10.138(R~2=0.999 6),linear range: 0.322 4～2.901 6 μg,mean extraction recovery: 96.21%(n=5).ConclusionThe method is simple,sensitive and rapid,and the contents of catalpol in processed Radix Rehmanniae products from different areas are different.更多还原
