    [摘要]
    用 FT- NMR波譜儀測定了 6個不同產(chǎn)地黃連特征總提物的 1 HNMR圖譜,并對特征信號進行了歸屬。從特征總提物中分得并鑒定了小檗堿和棕櫚堿。分析結(jié)果指出,每種黃連的 1 HNMR圖譜都顯示出原小檗堿型生物堿的特征共振峰。黃連偽品無此信號

    [Abstract]
    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.
