摘 要:目的:利用超高效液相色谱法测定了分布于新疆的不同生长时期多伞阿魏中DAW22的含量。方法:采用固相萃取(SPE)净化,测定条件Waters ACQUITY UPLC BEH C18色谱柱(2.1 mm×50 mm,1.7μm),以甲醇-1%甲酸水溶液为流动相,进行梯度洗脱,流速0.2 m L·m L^(-1),柱温30℃,波长316 nm,进行含量测定。结果:DAW22进样量在6.21~124.2 ng(r=1.000 0)与其峰曲线下面积呈良好的线性关系,平均回收率99.81%,RSD 2.0%,生长在5月9日的多伞阿魏植株中DAW22的含量最高。结论:建立的多伞阿魏中DAW22的质量控制研究方法准确、可靠、重复性好,能够用于多伞阿魏的质量控制。Objective: To establish UPLC method for the determination of DAW22 from Ferula ferulaeoides of different growth periods in Xinjiang. Method: Solid phase extraction( SPE) was used for purification,and the determination was performed on ACQUITY UPLC BEH C18( 2. 1 mm × 50 mm,1. 7 μm)with methanol-1% formic acid solution as the mobile phase for gradient elution. The flow rate was 0. 2 m L·min-1.Column temperature was 30 ℃ and UV detection wavelength was 316 nm. Result: The sample volume showed good linear relationship with area under the peak curve within the range of 6. 21-124. 2 ng( r = 1. 000 0) for DAW22.The average recovery was 99. 81%,and the RSD was 2. 0%. The content of DAW22 was highest for those grown in May 9th. Conclusion: This method is accurate,simple and reproducible,and can be applied to the quality control of F. ferulaeoides.
