摘要:目的使用高效液相色谱法测定不同产地苦参药材中槐果碱、苦参碱、氧化槐果

碱、槐定碱、氧化苦参碱的含量。方法使用Agilent ZORBAX NH2(4.6 mm×150 mm,5 μm)色谱柱,流动相为乙腈-无水乙醇-3%磷酸溶液(84∶10∶6),流速为1 mL/min,检测波长为210 nm。结果槐果碱在0.022 88~0.114 4 μg(r=0.999 7)、苦参碱在0.0832~0.416 0 μg

(r=0.999 7)、氧化槐果碱在0.376 2~1.836 0 μg(r=0.999 8)、槐定碱在0.104 4~0.522 μg (r=0.9992)、氧化苦参碱在0.491 2~2.456 μg(r=0.999 9)范围呈良好的线性关系,加样回收率分别为101.63%(RSD=2.08%)、98.29%(RSD=1.87%)、101.89%(RSD=1.97%)、99.87%(RSD=2.06%)、102.66%(RSD=1.34%)。结论该方法简便、灵敏、准确,可用于苦参药材的质量控制。

Abstract:Objective To determine the content of sophocarpine, matrine, oxysophocarpine,sophoridine, oxymatrine in Sophora Flavescentis Radix from different areas. Methods Agilent ZORBAX NH2 column (4.6 mm×150 mm, 5 μm) was used with mobile phase of acetonitrile-ethanol-3% phosphate (84∶10∶6), at a flow rate of 1 mL/min. The wavelength of detection was 210 nm. Results The linear range of sophocarpine, matrine, oxysophocarpine, sophoridine and oxymatrine were 0.022 88-0.114 4 μg (r=0.9997), 0.083 2-0.416 0 μg (r=0.999 7), 0.376 2-1.836 0 μg (r=0.999 8), 0.104 4-0.522 μg (r=0.999 2), 0.491 2-2.456 μg (r=0.999 9),respectively. The average recovery were 101.63% (RSD=2.08%), 98.29% (RSD=1.87%),101.89% (RSD=1.97%), 99.87% (RSD=2.06%), 102.66% (RSD=1.34%), respectively. Conclusion The method is simple, rapid and accurate, and suitable for the quality control of Sophorae Flavescentis Radix.
