Abstract:Objective To establish an high performance liquid chromatography method for content determination of four kinds of phenylphthalides in Radix Angelicae Sinensis, and to evaluate its quality by cluster analysis. Methods The Agilent Eclipse Plus C18 column (4.6 mm×150 mm, 3.5 μm) was used as the column. The mobile phase was composed of acetonitrile-water with gradient elution at a flow rate of 1 ml/min. The column temperature was 35℃. The detection wavelength were set at 284 nm for senkyunolide I and senkyunolide A, 326 nm for ligustilide, and 260 nm for 3-butylidenephthalide. SPSS 26.0 statistical software was performed on cluster analysis. Results All the four components could achieve baseline separation with good liner relationships (r = 0.9999), and the calibration curves of senkyunolide I, senkyunolide A, ligustilide and 3-butylidenephthalide were in good linearity over the range of 5.85×10-3 to 0.234 μg, 1.12×10-2 to 0.446 μg, 0.416 to 16.64 μg, 5.20×10-3 to 0.208 μg. The average recoveries were between 98.33% and 102.22%, with the RSD between 1.36% and 3.61%. The samples of Radix Angelica Sinensis from different habitats could be divided into two species according to the content in different parts. For Radix Angelicae Sinensis head, the ones from Yunnan Qujing 1, Yunnan Baiyao Base 1 and Yunnan Nujiang were grouped together, and the others were grouped together. For Radix Angelicae Sinensis body, the ones from Yunnan Qujing 1, Yunnan Nujiang 2, Hubei Shennongjia, and Yunnan Baiyao Base 1 were grouped together, and the others were grouped together. Conclusion The method is simple, accurate and specific, for the determination of four phenylphthalides in Radix Angelicae Sinensis, which can provide reference for the quality evaluation and comprehensive development and utilization of Angelica Sinensis.
