摘要: 建立一种不同时期花生茎叶中阿魏酸含量的高效液相色谱(HPLC)检测方法并测定其含量。以水为溶剂,在单因素试验的基础上,通过正交试验优化花生茎叶中阿魏酸提取条件并优化检测条件。结果表明:HPLC最佳检测条件为色谱柱Venusil XBP C18,流动相乙腈∶0.3%磷酸水溶液为20∶80,流速1.0 mL/min,检测波长320 nm,在3.0~50.0 μg范围内,阿魏酸浓度与峰面积呈现良好的线性关系,平均回收率为100.4%,RSD=1.19%。此方法分析速度快、操作简便、结果的精密度与重现性好,可作为花生茎叶中阿魏酸含量的测定方法。阿魏酸最优提取条件:料液比为1∶100(g∶mL)、提取温度为95 ℃、提取时间为30 min;不同时期花生叶中阿魏酸含量均高于茎,其中初花期花生叶中阿魏酸含量是茎的2.1倍,成熟期花生叶中阿魏酸含量是茎的2.9倍。

Abstract: A high performance liquid chromatography(HPLC)method was established for the determination of ferulic acid in peanut stems and leaves at different stages. Based on the single factor experiments, orthogonal experiment was used to optimize extraction condition and the HPLC detection condition. The best HPLC condition was as follows: the analytical column was a Venusil XBP C18; The mobile phase consisted of acetonitrile-0.3% phosphoric acid aqueous solution(20∶80); Flow rate was 1.0 mL/min, and detection wave length was 320 nm. In the range of 3.0~50.0 μg, there is a good linear relationship between ferulic acid concentration and the peak area. The average recovery of the method was 100.4% with a RSD of 1.19%(n=6). This method has the advantages of fast analysis, simple operation, good precision and reproducibility, and is suitable for determination of ferulic acid content in peanut stems and leaves. The optimal extraction condition for ferulic acid was: ratio of material to liquid 1:100(g:mL), extraction temperature 95 ℃, extraction time 30 min. The content of ferulic acid in peanut leaves was higher than that in stems at all stages. At initial flowering stage, the content of ferulic acid in peanut leaves was 2.1 times that of stems. At the ripening stage, the ferulic acid content was 2.9 times that of the stem.

Key words: peanut stems and leaves, ferulic acid, HPLC
