本文报告应用化学和光谱法(^1H, ^1^3C NMR, ^1^3C,^1H COLOC, noeds和NOESY) , 对分自川产家种华西贝母(F. siechuanica S. C. Che)藓茎中的碱N确证为西贝素β-氮氧化物(imperialine β-N-oxide )3以及3的二维核磁共振谱的研究. 同时, 对文献[4]报告的3中某些^1^3C信号化学位移的归属也进行了纠正.

关键词: 二维核磁共振谱法, 贝母碱, 氮氧化物

Imperialine β-N-oxide 3 isolated from the bulbs of fritillaria siechuanica S. C. Che was identified on the basis of the chemical and spectral methods. Its all ^1H and ^!^3C-signals have been assigned unambigously based on studies of 2D NMR. In addition, assigments of the chemical shifts of some ^!^3C-signals of 3 reported in literature 4 were revised.

Key words: PEIMINE, 2D NMR SPECTROMETRY, NITROGEN OXIDE
