摘 要:为了对六神曲质量进行有效评价,收集了陕西省六神曲主要生产厂家不同月份生产的24批样品,采用电位滴定法,建立了六神曲总有机酸含量测定方法,滴定至pH 8.2为终点。结果表明,该方法重现性、稳定性好,回收率在97.37%~100.88%;总有机酸含量在0.69%~2.05%,说明此方法可用于六神曲的质量控制,为有效控制质量、提升质量标准提供了科学依据。In order to effectively evaluate Liushenqu, the study collects 24 branches of Liushenqu samples from main manufactures in different months in Shaanxi Province, adopts potentiometric titration, establishes the method for the determination of total organic acids in Liushenqu. Potentiometric titration was used to titrate to pH 8.2 as the end point. The method had good reproducibility and stability, and the recovery was 97.37%~100.88%.The content of total organic acid in 24 batches of Liushenqu was between 0.69% and 2.05%.The method can be used for the quality control of Liushenqu, to provide scientific reference for effective quality control and quality standard improvement.
