摘要: 由于谱峰拥挤和重迭、关附庚素的一部分1H和13C谱峰用一般核磁共振方法难于确定归属。本工作采用选择性远程DEPT、一维COSY和-维接力COSY等新技术作了研究,其1H和13C谱峰归属全部得到确定。结果有助于此类化合物的化学结构测定。

Abstract: The 1H and 13C NMR spectra of guan-fu base G (1) were studied by selec-we long-range 13C DEPT, 1 D COSY and 1 D relay COSY new techniques, otal assignment of 1H and 13C NMR spectra of the compound can be obtained. The results obtained showed that the techniques described in this paper are very ffective and convenient for the structure determination and oectral assignment of this class of compounds.
