乌梅中主要有机酸的定量动态分析

Quantitative dynamic analysis of organic acids in Fructus Mume by isota-chophoresis

影响药材成分的因素很多，为探明影响乌梅主要有机酸的含量问题，应用简便、快速、准确的毛细管等速电泳法对不同采收期乌梅的主要有机酸：柠檬酸和苹果酸含量的动态变化进行了分析，同时对不同加工方法、不同梅品种加工成的乌梅中主要有机酸含量也进行了测试，结果发现采收期、加工方法及梅品种对乌梅的有机酸含量均有影响。此结果为乌梅的综合质量评价、最佳采收期、最优加工方法及梅品种的选择提供了参考依据。

A simple,rapid and accurate isotachophoresis method was developed for the assayof citric acid and malic acid contents in traditional Chinese medicine Fructus Mume with differentharvest time,different processing methods or different plant origins。The results showed that theharvest time,processing method and plant orginal influenced the quality of Fructus Mume。Thisstudy provided a basis for conprehensive quality assessn1ent and choicc of the optimum harvesttime,the best processing method and the better plant original of Fructus Mume。
