TITLE:
摘要: 目的:建立苗药妇肤康喷雾剂的高效液相色谱(HPLC)指纹图谱。方法:色谱柱为Thermo Hypersil GOLD C18,流动相为乙腈-0.2%冰醋酸(梯度洗脱),检测波长为262 nm,流速为0.6 mL/min,柱温为25 ℃,进样量为10 μL。以6′ -羟基-爵床定B为参照,绘制10批样品的HPLC图谱,采用中药色谱指纹图谱相似度评价系统软件(2004 A版),对10批样品进行相似度评价,确定10批样品的共有峰。采用建立的方法测定10批样品中6′ -羟基-爵床定B和爵床定B的含量。结果:10批样品的HPLC指纹图谱有12个共有峰,相似度均大于0.90,其HPLC指纹图谱与对照指纹图谱具有较好的一致性。10批样品中6′ -羟基-爵床定B和爵床定B含量分别为1.64~5.84、0.83~2.78 mg/100 mL。结论:建立的方法操作简便,结果准确可靠,可为妇肤康喷雾剂的质量评价提供参考。
ABSTRACT: OBJECTIVE: To establish HPLC fingerprint of Miao medicine Fufukang spray. METHODS: The determination was performed on Thermo Hypersil GOLD C18 column with mobile phase consisted of acetonitrile-0.2% glacial acetic acid (gradient elution) at the flow rate of 0.6 mL/min. The detection wavelength was set at 262 nm, and column temperature was 25 ℃. The sample size was 10 μL. Using 6′ -hydroxyl-justicidin B as reference control, HPLC chromatograms of 10 batches of samples were drawn. Similarity evaluation system software (2004 A edition) of TCM fingerprint was used to evaluate the similarity and determine common peaks of 10 batches of samples. The established method was used to determine the contents of 6′ -hydroxyl-justicidin B and justicidin B in 10 batches of samples. RESULTS: There were 12 common peaks in HPLC fingerprints of 10 batches of samples with similarity>0.90. HPLC fingerprint showed a good consistency with the control fingerprint. The contents of 6′ -hydroxyl- justicidin B and justicidin B in 10 batches of samples were 1.64-5.84, 0.83-2.78 mg/100 mL, respectively. CONCLUSIONS: The established method is simple, accurate, reliable and suitable for quality evaluation of Fufukang spray.
