目的 建立小兒磨積片的質(zhì)量標(biāo)準(zhǔn)。方法 采用薄層色譜法對(duì)制劑中甘草、厚樸進(jìn)行定性鑒別；采用高效液相色譜法對(duì)橙皮苷進(jìn)行定量測(cè)定。色譜柱為美國(guó)Dikma公司C¹⁸柱（250 mm×4.6 mm，5 μm），以乙腈-0.4%磷酸溶液（45∶55）為流動(dòng)相，體積流量1 mL/min，檢測(cè)波長(zhǎng)283 nm。結(jié)果 薄層色譜鑒別斑點(diǎn)清晰，陰性樣品無干擾；定量測(cè)定中橙皮苷進(jìn)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(jiǎn)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.
