摘 要 目的:完善和提高咳清胶囊的质量标准。方法:根据2015年版《中国药典》(四部)通则0502法对咳清胶囊中吉祥草、桑白
皮进行薄层色谱(TLC)鉴别[展开剂分别为二氯甲烷-乙酸乙酯-甲酸(10 ∶ 4 ∶ 0.2,V/V/V)、乙酸乙酯-甲醇-浓氨试液(12 ∶ 2 ∶ 1,V/V/
V)];采用高效液相色谱法(HPLC)同时测定咳清胶囊中吗啡、磷酸可待因的含量[色谱柱为XBridge C18,流动相为乙腈-0.01 mol/L
磷酸二氢钾水溶液(以 5%磷酸溶液调节 pH 至 2.7)(5 ∶ 95,V/V),流速为 1.0 mL/min,检测波长为 210 nm,柱温为 35 ℃,进样量为
10 µL]。结果:在吉祥草、桑白皮供试品TLC图谱中,与对照药材图谱相应的位置上显相同颜色的斑点,且阴性对照无干扰。吗
啡、磷酸可待因检测进样量的线性范围分别为 0.301 56~2.110 90、0.064 93~0.454 52 µg(r=0.999 9、0.999 9),检测限分别为
0.000 10、0.001 28 µg,定量限分别为0.000 34、0.042 5 µg,精密度、稳定性(12 h)、重复性、耐用性试验的RSD均小于3%(n=6),平
均加样回收率分别为96.18%、95.95%(RSD=1.78%、2.07%,n=6)。18批咳清胶囊样品中吗啡、磷酸可待因的含量范围分别为
0.97~1.37、0.16~0.37 mg/g。结论:本研究建立了咳清胶囊吉祥草、桑白皮的TLC鉴别方法以及吗啡、磷酸可待因的HPLC含量
测定方法,操作简便、准确可靠、专属性强,提升和完善了该制剂的质量标准。

ABSTRACT OBJECTIVE:To optimize and improve the quality standard for Keqing capsules. METHODS:According to general
rule 0502 method stated in 2015 edition of Chinese Pharmacopeia(part Ⅳ),TLC method was used to identify Reineckia carnea
and Morus alba in Keqing capsules [the developing solvents were dichloromethane-ethyl acetate-formic acid(10 ∶ 4 ∶ 0.2,V/V/V)
and ethyl acetate-carbinol-ammonia(12 ∶ 2 ∶ 1,V/V/V),respectively]. The contents of morphine and codeine phosphate in Keqing
capsules were determined by HPLC. The determination was performed on XBridge C18 column with mobile phase consisted of
acetonitrile-0.01 mol/L potassium dihydrogen phosphate aqueous solution (pH value adjusted to 2.7 with 5% phosphoric acid
solution)(5 ∶ 95,V/V)at the flow rate of 1.0 mL/min. The detection wavelength was set at 210 nm,and the column temperature
was 35 ℃. The sample size was 10 µL. RESULTS:In TLC of R. carnea and M. alba in samples,same color spots were shown in
the corresponding positions of reference substance
