摘要:

采用HPLC法建立黄芩中黄酮类成分的特征图谱,以6个主要特征峰的回收率和特征图谱相似度为指标,优选固相萃取小柱填料、淋洗液和洗脱条件。最终确定C18固相萃取小柱对6个成分的回收率最高,淋洗液为甲醇0.3%甲酸(20∶80,V/V),洗脱液为甲醇(含0.3%甲酸),纯化后6个主要特征峰的回收率均在89%以上,HPLC特征图谱相似度大于0.98。采用HPLC特征图谱指导优化黄芩黄酮类成分的固相萃取纯化方法,可保持纯化前后黄芩有效组分中化学成分的一致性。

Abstract:

The specific chromatogram of flavonoids in Radix Scutellariae was established by HPLC in this paper. The column filling, eluent and the elution condition of solid phase extraction were optimized using the recovery rates and specific spectral similarity of six main characteristic peaks in HPLC specific chromatogram as indexes. Experimental results confirmed that C18 solid phase extraction (SPE) possessed the highest recovery rates of six components. The SPE column was rinsed with methanol0.3% formic acid(20∶80,V/V), and then was eluted finally with methanol (containing 0.3% formic acid). After being purified, the recovery rates of six components were all over 89%, and the similarity of characteristic chromatogram was higher than 0.98. Based on HPLC characteristic chromatogram, the optimized purification process of flavonoids in Radix Scutellariae with solid phase extraction can ensure that the main effective components remain consistent before and after purification of Radix Scutellariae.

Key words: Radix Scutellariae, solid phase extraction, flavonoids, HPLC specific chromatogram
