Determination Content of 5 components in Huannao Yicong Decoction by HPLC
Objective To establish a method for the determination of 5 components:Ferulic acid,Ligusticolide Ⅰ,Ligusticolide A,Ligustilide and Angelica lactone A in Huannao Yicong Decoction,and explore the material basis.Methods HPLC was per-formed on Agilent Extend-C18(4.6 mm ×250 mm,5μm)column.Mobile phase:methanol(A),0.3%phosphoric acid solu-tion(B),acetonitrile(C);Flow rate:1m L/min;Column temperature:30℃;Detection wavelength:280nm.Results A total of 5 chemical constituents of chuanxiong were detected in Huannao Yicong Decoction.The established method has no negative inter-ference,and the five components achieved good separation effect,and the linear range of standard curve is good.Conclusion This method is simple,stable and reproducible,and can be used for the quantitative detection of Chuanxiong in Huannao Yicong prescription,providing evidence for the material basis in the treatment of AD.
