【摘要】：目的:对不同产地党参药材及其水提物的红外指纹图谱进行比较分析,说明党参的红外光谱特点。方法:采用傅里叶变换红外光谱(Fourier transform infrared spectroscopy,FTIR)分析方法,采集党参药材及水提物的红外光谱,对光谱进行双指标序列分析。结果:7个产地党参药材的红外图谱在3 385、2 929、2 360、1 734、1 541、1 507、1 456、1 250、870、818、778、668 cm~(-1)附近有12个共有峰,主要对应党参中的多糖、党参苷、内酯类等成分。以陵川党参为对照,得到原药材的平均共有峰率为72.74%,水提物的平均共有峰率为58.54%,其中原药材中壶关党参与陵川党参的关系最为接近。结论:FTIR图谱分析可为党参的鉴定及质量控制提供补充。
[Abstract]:Objective: to compare and analyze the infrared fingerprint of Codonopsis pilosula and its aqueous extracts from different areas, and to explain the infrared spectrum characteristics of Codonopsis pilosula.Methods: Fourier transform infrared spectroscopy (transform infrared spectroscopy FTIR) was used to collect the infrared spectra of Codonopsis pilosula and its aqueous extracts.Results: there were 12 peaks in the infrared spectra of Codonopsis pilosula from 7 producing areas, which were mainly corresponding to the polysaccharides, Codonopsis glycosides and lactones of Codonopsis pilosula.Compared with Lingchuan Codonopsis pilosula, the average common peak rate was 72.74 and the average common peak rate of water extract was 58.54. The relationship between Huguan Party and Lingchuan Codonopsis pilosula was the closest.Conclusion the analysis of FTIR spectra can provide a supplement for the identification and quality control of Codonopsis pilosula.
