摘要:目的 建立山楂消脂胶囊中大黄蒽醌类成分一测多评法的分析方法,并进行方法学考察。方法 以大黄素为内参照物,建立芦荟大黄素、大黄酸和大黄酚与大黄素间的相对校正因子。分别采用外标法和一测多评法测定山楂消脂胶囊中4种蒽醌类成分的含量,以验证一测多评法的合理性、可行性和可重复性。结果 一测多评法的计算结果与外标法的实测值之间无显著差异。结论 一测多评法可作为一种质量评价模式用于山楂消脂胶囊中蒽醌类成分的质量评价。

Abstract: Objective To establish a method for the quantitative analysis of multi-component with a single-marker (QAMS) to determine the contents of four rhubarb anthraquinones in Shanzha Xiaozhi capsules; To conduct methodology investigation. Methods Emodin was set as the internal reference substance, and the relative correlation factors of aloe emodin, rhein, chrysophanol to emodin were calculated and evaluated. The contents of these four anthraquinones were determined by the external standard method and QAMS, respectively. Rationality, feasibility and repeatability of the QAMS method were verified by comparing the results obtained from the two different methods. Results The QAMS method and HPLC method did not show significant difference in results. Conclusion QAMS method can be used as a quality assessment model for quantity evaluation of anthraquinones in Shanzha Xiaozhi Capsules.

Key words: QAMS; HPLC; Shanzha Xiaozhi Capsules; anthraquinone; relative correlation factor

山楂消脂胶囊是佛山市中医院院内制剂(批准文号:粤药制字Z20060045),由山楂和大黄2味中药组成,具有行气化痰、消积除滞、清热凉血作用,临床主要用于高脂血症、肥胖症等患者[1]。山楂消脂胶囊可通过抗炎症反应,降低同型半胱氨酸水平,稳定冠状动脉粥样硬化斑块,从而减少非急性期冠心病痰瘀证患者急性心血管事件的发生[2-3]。大黄是该药的主要成分之一,主要含大黄酸、大黄素、大黄酚、大黄素甲醚、芦荟大黄素等蒽醌类成分[4]。原质量标准仅采用薄层法进行定性鉴别,为更好地有效控制山楂消脂胶囊的质量,本研究采用一测多评法[5-7]同时测定方中芦荟大黄素、大黄酸、大黄酚和大黄素4个成分的含量,为该制剂提供快速、准确、可靠的检测方法。……
