摘要: 以五角枫叶片为实验材料,经预处理后用反相高效液相色谱测定了植物组织中水杨酸的含量.该方法摸索出了使水杨酸与其他酸性(或杂质)组分很好分离的液相色谱条件,建立了植物组织中水杨酸的定性定量方法.用该方法测定水杨酸标样的回收率高于95%,精密度和重现性均较好(相对标准偏差为0.42%).用该方法对实际植物样品的分析也取得了较理想的结果.Abstract: Salicylic acid(SA) in the leaves of Acer mono was detected by reverse phase high performance liquid chromatography(RP-HPLC) after the tissues were pretreated.The analysis method for SA in the plant tissues was established.The recycle rate of this method was higher than 95%.Its relative standard deviation(RSD) was 0.42%.The results showed that SA was well separated from other acidic interferents, and the ideal quantitative data of SA in A.mono were obtained.
