用 FT- NMR波谱仪测定了 6个不同产地黄连特征总提物的 1 HNMR图谱 ,并对特征信号进行了归属。从特征总提物中分得并鉴定了小檗碱和棕榈碱。分析结果指出 ,每种黄连的 1 HNMR图谱都显示出原小檗碱型生物碱的特征共振峰。黄连伪品无此信号
FT-NMR spectrometer was used to determine the 1 HNMR spectra of the total extracts of Coptis chinensis from 6 different origins, and the characteristic signals were assigned. Berberine and palmitine were separated and identified from the total extracts of the characteristics. The analysis results indicate that the 1 H NMR spectrum of each Coptis shows the characteristic resonance of the original berberine alkaloid. Coptis counterfeit without this signal
