摘要
目的研究不同生长年限山西党参的指纹图谱,为科学评价党参的内在质量提供参考。方法采用RP-HPLC法,色谱柱:GraceSmart RP18(250mm×4.6mm,5μm),以乙腈-0.1%冰醋酸为流动相,流量0.6mL/min,检测波长为268nm,柱温30℃。结果党参样品HPLC指纹图谱可明显显示不同年限党参样品的差异性和相似性,精密度、稳定性和重复性试验的RSD均<3%,用党参炔苷作为参照物可确认党参样品中的活性成分。结论本方法操作简便,结果稳定可靠,且利用指纹图谱的整体性,可以对山西党参药材的质量控制提供有益的参考。
Objective Chromatography fingerprint of Radix Codonopsis of different age from Shanxi province was studied to provide the reference for the science appraisal of intrinsic quality of Radix codonopsis. Method A RP-HPLC method was applied on GraceSmart-RP18 (250 mm×4.6 mm, 5 μm) column with acetonitrile-0.1% acetic acid gradient elution as mobile phase, and the flow-rate was 0.6 mL/min. The detection wavelength was at 268 nm and the column temperature was at 30 ℃. Result Chromatography fingerprint of Radix Codonopsis can demonstrate obviously the difference and the similarity of Radix Codonopsis of different age. The RSD were lower than 3% in the precision, stability and the repetitiveness trial, and the codonopsis pilosula alkyne glucoside can be used as the reference to identify the active composition of Radix Codonopsis. Conclusion The method was simple, reproducible and reliable. The integrity of fingerprint can be used to supply the reference for the quality control of Radix Codonopsis from Shanxi provice.
