Effect of Different Dry Methods on Ferulic Acid in Different Parts of Ligusticum chuanxiong

Objective:To study the effect of different dry methods on ferulic acid in different parts of Ligusticum chuanxiong.Method:The content of ferulic acid in L.chuanxiong from different dry methods and different parts was determined by HPLC.Result:There was a good linear relationship between ferulic acid and peak area when the sample injection was from 0.005 74-0.918 4 μg(r=0.999 9);the quantification limit was 0.114 8 mg·L-1;the average recovery was 100.7%,and RSD was 1.07%(n=9).The ferulic acid content in different parts of L.chuanxiong arranged in descending order was:rhizomestemleaf.Different dry methods had different influence on the ferulic acid content in different parts of L.chuanxiong.Conclusion:Ferulic acid content in different parts of L.chuanxiong is different.Sunshine is not suitable for rhizome,oven-drying after sunshine is suitable for L.chuanxiong.
