摘要
建立科学完善的牡丹皮配方颗粒质量评价体系,包括含量测定方法、特征图谱方法和质谱分析方法。利用高效液相色谱法对牡丹皮配方颗粒进行含量测定,颗粒中的芍药苷平均质量分数为1. 72%,丹皮酚平均质量分数为1. 42%。利用特征图谱对牡丹皮配方颗粒进行整体定性,包含7个特征峰,分别为没食子酸,对羟基苯甲酸,氧化芍药苷,芍药苷,四没食子酰葡萄糖,1,2,3,4,6-五没食子酰葡萄糖,丹皮酚。利用质谱分析进行化学成分分析,共鉴定牡丹皮配方颗粒中40个化合物,包括没食子酸类、芍药苷类、丹皮酚类、黄酮类及苯甲酸类化合物。该研究将多种分析手段应用于牡丹皮配方颗粒的质量评价体系中,对提高质量评价和过程质量控制水平起到积极的促进作用。
A scientific and perfect quality evaluation system for Moutan Cortex Formula Granules was established,including content determination method,characteristic chromatogram method and mass spectrometry method. The content of paeoniflorin and paeonol in Moutan Cortex Formula Granules was determined by high performance liquid chromatography( HPLC),and the average content was 1. 72% and 1. 42%,respectively. The characteristic chromatogram was used to characterize Moutan Cortex Formula Granules,which contained 7 characteristic peaks,namely gallic acid,p-hydroxybenzoic acid,oxypaeoniflorin,paeoniflorin,tetragalloyl glucose,1,2,3,4,6-penta-O-galloyl-β-D-glucose and paeonol. A total of 40 compounds in Moutan Cortex Formula Granules,including gallic acids,paeoniflorins,paeonols,flavonoids and benzoic acids,were identified by mass spectrometry. In this study,a variety of analytical methods were used to evaluate the quality system of Moutan Cortex Formula Granules,which could play a positive role in improving the level of quality evaluation and process quality control.
