18(2)(250 mm×4.6 mm,5 μm),流動相為乙腈-0.1%磷酸溶液(15:85)(每100 mL 加0.1 g 庚烷磺酸鈉),柱溫40 ℃,體積流量1.0 mL/min,檢測波長220 nm。結(jié)果 嗎啡在3.907~97.680 μg/mL 與峰面積積分值呈良好線性關(guān)系,平均回收率為96.78%,RSD=0.64%(n=6)。結(jié)論 所建立的方法操作簡便、測定準確、重復(fù)性良好,可用于二母安嗽片的質(zhì)量控制。;Objective To establish a method for the determination of morphine in Ermu Ansou Tablet. Methods RP-HPLC was applied to determine the content of morphine. An RP-HPLC method was established with Luna C18 column (2) (250 mm × 4.6 mm, 5 μm) by a gradient elution using acetonitrile-0.1% phosphoric acid (15:85) (0.1 g sodium heptanesulfonate added into 100 mL); The flow rate was 1.0 mL/min and the wavelength was set at 220 nm. The column temperature was 40 ℃. Results The relationship between injection level and area of morphine was evaluated to be linear at the range of 3.907—97.680 μg/mL. The average recovery rate was 96.78%, and RSD was 0.64% (n = 6). Conclusion The quantitative methods established in this study are convenient, accurate, and reproducible, and can be used as the quality control standard for Ermu Ansou Tablet."/>
