18柱(250 mm×4.6 mm,5 μm),以乙腈-0.4%磷酸溶液(45∶55)為流動相,體積流量1 mL/min,檢測波長283 nm。結(jié)果 薄層色譜鑒別斑點清晰,陰性樣品無干擾;定量測定中橙皮苷進樣量在0.044~0.264 μg與峰面積線性關(guān)系良好(r=0.999 7);平均回收率為98.90%,RSD為1.49%(n=6)。結(jié)論 建立的方法操作簡單,專屬性和重現(xiàn)性好,可作為該制劑的質(zhì)量控制方法。;Objective To establish the quality standard for Xiao’er Moji Tablets (XMTs). Methods Glycyrrhizae Radix and Magnoliae Officinalis Cortex were identified by TLC. Hesperidin was determined by HPLC. The chromatographic column was a Dikma-C18 column (250 mm × 4.6 mm, 5 μm) with a mobile phase of acetonitrile-0.4% phosphoric acid solution (45:55). The flow rate was 1.0 mL/min; The detective wavelength was set at 283 nm. Results TLC spots developed were fairly clear and the negative sample showed no interference. The calibration curve was linear within range of 0.044-0.264 μg (r = 0.999 7). The average recovery was 98.90%, RSD was 1.49% (n = 6). Conclusion The method is accurate, sensitive, and specific. It could be used for the quality control of XMTs."/>
