摘要: 对12种西洋参中的7种人参皂苷进行HPLC同时测定,建立西洋参中人参皂苷含量测定的现代分析方法,并建立起西洋参人参皂苷类的色谱指纹图谱。HPLC测定条件:梯度洗脱,AlltimaC18色谱柱,乙腈-0.05%磷酸水溶液为流动相,流速为1.2ml/min,柱温为35℃,紫外检测器,检测波长203nm。在选定的最佳色谱条件下每种成分在各自的浓度范围内均具有较好的线性相关性,7种人参皂苷的加标回收率为94.1%~97.9%。对色谱指纹图谱进行相似度和聚类分析计算,得到了令人满意的结果。该法为西洋参样品的质量和品种鉴定提供了较全面的信息,并为HPLC应用于样品复杂组分的分析和鉴别开拓了新的领域。

Abstract: A modern HPLC analysis method was developed for the determination of seven major ginsenosides in 12 kinds of Panax quinquefolium. L. Their chromatographic fingerprints were established by HPLC. Separations and determinations were carried out by linear gradient elution under following conditions: Alltima C18 (250mm×4.6mm, 5μm) column, acetonitrile-0.05% phosphoric acid solution as mobile phase, detection length of UV at 203nm, flow-rate of 1.2ml/min, column temperature of 35 ℃. The obtained results indicated that the developed method was simple, accurate and reliable for the determination of seven ginsenosides in Panax quinquefolium. L with a good linearity with the recovery ranges of 94.1%~97.9%. Hierarchical clustering analysis was performed and the similarity of the HPLC chromatograms was analyzed for the research of fingerprints and classificationo f Panax quinquefolium.L samples.
