摘要: 本研究分别建立葛根超微粉和细粉的UPLC指纹图谱,并对其进行对比研究。采用ACQUITY UPLC  BEH C18(50 mm×2.1 mm,1.7 μm)色谱柱,以乙腈-0.1%磷酸水溶液为流动相,检测波长254 nm,体积流量0.2 mL/min,柱温30 ℃,进样量2 μL,进行梯度洗脱。以3′-羟基葛根素、葛根素、3′-甲氧基葛根素、大豆苷、染料木苷、大豆苷元为参照物,对10批次葛根超微粉及10批次细粉进行指纹图谱分析,并进行相似度分析。建立了葛根超微粉及细粉的UPLC指纹图谱,标定葛根细粉共有峰22个,葛根超微粉共有峰24个,并用对照品指认了6个色谱峰,方法精密度、重复性及稳定性良好,两者在共有峰上无明显差别,峰面积有较为明显的差别。结果表明该方法稳定准确,建立的UPLC指纹图谱能从整体上反映出葛根超微粉及细粉的化学成分信息,为葛根细粉及超微粉的质量标准提供参考。

Abstract: To establish UPLC fingerprint of Ultra-micro and Normal powder of Pueraria Radix respectively and compare the fingerprint.The UPLC chromatographic column was Acquity UPLC BEH C18(50 mm×2.1mm,1.7 μm).The mobile phase was acetonitrile-0.1% phosphoric acid water with gradient elution wavelength was 230nm and column temperature was 30 ℃ with the flow rate of 0.2 mL/min.The fingerprints of 10 batches of Ultra-micro and 10 batches of Normal were analyzed with 3′-hydroxy puerarin,puerarin,3′-methoxy puerarin,daidzin,genistin and daidzein the similarity analysis was carried out.The results of methodological study met technical requirements of UPLC fingerprint.The UPLC fingerprints of ultra –micro and normal powder of Pueraria Radix had obvious difference in area of common peaks but less differences in number of common peaks.The UPLC method was stable and accurate and could reflect the whole chemical composition information and provide a basis for the establishment of quality standard for Ultra-micro and Normal powder of Pueraria Radix.
