目的 建立清眩軟膠囊的定性鑒別和定量測(cè)定方法。方法 采用TLC法對(duì)本方中的川芎、荊芥穗和薄荷進(jìn)行定性鑒別；采用HPLC法對(duì)方中主要成分歐前胡素進(jìn)行測(cè)定。Agilent C₁₈色譜柱（250 mm×4.6 mm，5 μm）；以乙腈-水（42.5：57.5）為流動(dòng)相；檢測(cè)波長(zhǎng)300 nm，柱溫為35℃，體積流量為1.5 mL/min。結(jié)果 薄層色譜斑點(diǎn)清晰，陰性樣品無干擾。歐前胡素在1.09～54.55 μg/mL與峰面積呈良好的線性關(guān)系，平均回收率為97.0%，RSD值為0.77%（n=6）。結(jié)論 所建立的定性和定量方法結(jié)果可靠、準(zhǔn)確，重現(xiàn)性好，無干擾，可用于清眩軟膠囊的質(zhì)量控制。

Objective To establish the quality control method for Qingxuan Soft Capsule including qualitative identification and quantitative determination. Methods TLC was applied to identifing Chuanxiong Rhizoma, Schizonepetae Spica, and Menthae Haplocalycis Herba. HPLC method was applied to determining imperatorin in Qingxuan Soft Capsule. The analytical column was Agilent C₁₈ (250 mm × 4.6 mm, 5 μm), and the mobile phase was acetonitrile-water (42.5:57.5). The detection wavelength was at 300 nm. The column temperature was at 35℃, and the volume flow was 1.5 mL/min. Results The TLC spots were distinct and reproducible. The linear range of imperatorin was 1.09-54.55 μg/mL. The average recovery rate was 97.0% with RSD 0.77% (n=6). Conclusion The qualitative and quantitative methods established are feasible, accurate, and reproducible, which can be well used for the quality control of Qingxuan Soft Capsule.
