摘要
目的 建立理中丸高效液相色谱(HPLC)指纹图谱并测定绿原酸(chlorogenic acid)、甘草苷(liquiritin)、党参炔苷(lobetyolin)、甘草素(liquiritigenin)、甘草酸(glycyrrhetinic acid)、白术内酯Ⅲ(atractylenolide Ⅲ)、白术内酯 Ⅱ(atractylenolideⅡ)、白术内酯Ⅰ(atractylenolide Ⅰ)和10-姜酚(10-gingero)的含量,为其质量控制提供依据.方法 采用Eclipse Plus C18色谱柱,以乙腈体积分数-0.1％磷酸水溶液为流动相,梯度洗脱,流速0.8 mL·min-1,检测波长215和254 nm,柱温30℃;通过相似度评价,结合化学模式识别,对21批理中丸指纹图谱进行评价及分析,并对9种指标成分进行定量测定.结果 21批理中丸指纹图谱中共标定29个共有峰,各批次的相似度均大于0.9,3个厂家21批样品可聚为3类,组间差异化合物有16个.9种成分在各自线性范围内线性关系良好(r≥0.998 7);平均加样回收率95.34％～104.41％,相对标准偏差(RSD)0.95％～2.95％.结论 建立的理中丸指纹图谱及多成分定量测定方法简单、准确、重现性较好,可用于理中丸整体质量评价.
Abstract
OBJECTIVE To establish the HPLC fingerprints,determine the contents of chlorogenic acid,liquiritin,lobetyolin,liquiritigenin,glycyrrhetinic acid,atractylenolide Ⅲ,atractylenolide Ⅱ,atractylenolide Ⅰ,10-gingerol in Lizhong Pills,and lay the foundation for its quality control.METHODS A Eclipse Plus C18 column was used with acetonitrile-0.1％aqueous phosphoric acid as the mobile phase in gradient elution at a flow rate of 0.8 mL·min-1.The detection wavelengths were set at 215 nm and 254 nm,and the column temperature was maintained at 30 ℃.Through similarity evaluation,combined with chemical pattern recognition,the fingerprints of 21 batches of Li Zhong Pills were evaluated and analyzed,and 9 index components were quantitatively determined.RESULTS The fingerprints of 21 batches of Lizhong Pills were established,with 29 peaks identified,the similarity of each batch was greater than 0.9,and 21 batches of samples from 3 manufacturers could be clustered into 3 categories,with 16 compounds differing between groups.Nine components showed good linear relationships within their respective linear ranges(r≥0.998 7),the average recoveries ranged from 95.34％to 104.41％,and the RSDs ranged from 0.95％to 2.95％.CONCLUSION The fingerprint and quantitative determination method of Lizhong Pills is simple,accurate and reproducible,and can be used for the evaluation of the overall quality of Lizhong Pills.
