通过对二十三个香茶菜植物中二萜类化合物的~1H NMR 参数的归纳,总结了这些化合物的主要质子信号的规律,用分子模型使分子立体结构(B,C 环构象和取代基构型)与峰形相关连,为此类化合物的鉴别和结构确定提供了依据.
By summarizing the 1H NMR parameters of the diterpenoids in twenty-three Chaxiangpai plants, the rules of the major proton signals of these compounds were summarized and the molecular stereostructure (the conformation and substituents of the B and C rings) Configuration) associated with the peak shape for the identification of such compounds and provide the basis for the structure determination.
