摘要

本研究的目的是建立并验证一种灵敏的反相高效液相色谱法(RP-HPLC)，用于测定山茱萸酸的含量。山茱萸酸是一种由植物提取物和精油组成的复杂混合物，其中包括山茱萸提取物。在高效液相色谱柱(Zorbax Eclipse XDB-C18 600 Bar (4.6?100毫米，1.8 ?m))。采用溶剂(磷酸(pH 2.5)和乙腈)的梯度法，在0.1 mL/min的流速下，可以从所研究的复杂混合物中有效地分离出usic酸和其他化合物。该方法的适宜性、线性度、精密度、准确度和选择性/特异性表明其可作为一种可靠的检测方法用于所研究的多成分中药制剂的稳定性研究。

The RP-HPLC method for analysis of usnic acid as potential marker of herbal drugs-based formulations containing Usnea barbata

The aim of this study was to develop and validate sensitive RP-HPLC method for determination of usnic acid, as potential marker substance of the herbal product for oromucosal use being the complex mixture of plant extracts and an essential oil, including the extract of Usnea barbata. Analysis of usnic acid in the tested formulation was performed through an extraction with methanol, prior to injection on the HPLC column (Zorbax Eclipse XDB-C18 600 Bar (4.6?100 mm, 1.8 ?m)). Employed gradient procedure of the solvents (phosphoric acid (pH 2.5) and acetonitrile), at flow rate of 0.1 mL/min allowed efficient and reproducible separation of usnic acid from other compounds present in the investigated complex mixture. The established suitability, linearity, precision, accuracy and selectivity/specificity of this assay implied its applicability as a reliable examination in the stability study of the investigated multi-ingredient herbal preparation.
