Determination of the Contents of Ferulic Acid in Angelica sinensis from Different Regions

The contents of ferulic acid in Angelica sinensis collected from different areas were investigated.The ferulic acid contents in A.sinensis from 4 different regions were determined by high performance liquid chromatography(HPLC).The chromatography conditions were as follow,ZORBAX SB-C18(4.6 mm×150 mm,5 μm)with mobile phase of 0.5% CH3COOH and CH3OH at 1.0 mL/min,and detected at wavelength of 275 nm with flow rate of 1.0 mL/min,column temperature of 25 ℃.The content of ferulic acid in different areas of Angelica sinensis were 0.713 0 mg/g(Dali),0.646 5 mg/g(Lijiang),0.629 4 mg/g(Chuxiong),0.630 1 mg/g(Baoshan) respectively.The ferulic acid content of A.sinensis from Dali was the highest.
