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

The ¹HNMR fingerprints of the general characteristic extracts (GCEs) of rhizoma of Coptis chinensis Franch. from six different localities were determined on FT-NMR spectrometer. The characteristic signals were analyzed and assigned on the basis of the consituents of the GCEs. Six samples of C. Chinensis showed clearly the characteristic resonance peaks of the alkaloids of protoberberine type, which could be used for the identification of C.chinensis. The faked products were devoid of such characteristics.
