摘要
[目的]研究干燥方法对蘼芜中阿魏酸含量的影响。[方法]采用高效液相色谱法测定不同干燥方法处理的蘼芜中阿魏酸的含量。[结果]阿魏酸在进样量0.011 48～0.114 8μg/ml浓度范围内,与峰面积呈良好的线性关系(r=0.999 9),平均回收率为100.1%,RSD为1.18%(n=9);采用晒后烘干法干燥的蘼芜中阿魏酸的含量为0.005 4%,RSD为1.55%;采用自然阴干法干燥的蘼芜中阿魏酸的含量为0.008 0%,RSD为1.80%;采用晒后烘干法干燥的蘼芜中阿魏酸的含量为0.010 5%,RSD为1.07%。结果表明,3种干燥方法中,以晒后烘干处理的蘼芜中阿魏酸的含量最高。[结论]蘼芜的最佳干燥方法为晒后烘干法。
[ Objective ] To study the effect of drying methods on the content of fendic acid in different parts of Ligusticum chuanxiong Hort.. [ Method ] The content of ferulic acid in Ligusticum chuanxiong Hort. was determined by HPLC. [ Result ] There was a good linear relationship between the concentration and peak area of ferulic acid when the sample injection ranged from O. 01148 to 0.1148 μg （ r = 0. 999 9 ）. The average recovery was 100.1% with the RSD of 1.18% （n = 9）. The content of ferulic acid in naturally sun-dried Ligusticum chuartxiong Hort. was 0. 005 4% with the RSD of 1.55% , while that was 0.010 5% with the RSD of 1.07% in those dried oven-drying after sunshine. As to Ligusticum chuartxiong Holt. , oven-drying after sunshine was superior to the above two methods. [ Conclusion ] Among the three drying methods, oven-drying after sunshine was the optimal one for Ligusticum chuanxiong Hort.
