本文以正相高效液相色谱法,用窗口图解技术对色谱条件进行了优化。对黄柏及其中成药中的有效成分——小檗碱、巴马亭的提取、测定条件、标准曲线进行了研究。并对两种含黄柏的中成药样品进行了分析。其中小檗碱的回收率均在97%以上,巴马亭的回收率均在96%以上。
In this paper, the chromatographic conditions were optimized using normal phase high performance liquid chromatography with windowed graphical techniques. The berberine and palmatine extraction, determination conditions, and calibration curves of the active ingredients in Phellodendron and its proprietary Chinese medicines were studied. Two samples of proprietary Chinese medicine containing cork were analyzed. Among them, the recovery rate of berberine was above 97%, and the recovery rate of bamatin was over 96%.
