摘　　要：用一维１ＨＮＭＲ谱、１Ｈ１ＨＣＯＳＹ谱和一维１３ＣＮＭＲ谱、ＤＥＰＴ谱研究辣椒碱分子和二氢辣椒碱分子及其混合物，得到１Ｈ和１３Ｃ的化学位移。Capsaicin, dihydrocapsaicin and their mixtures were studied by 1D\ 1H NMR spectra,\ 1H 1H COSY spectra, 1D\ 13 C NMR spectra and DEPT spectra. The\ 1H and\ 13 C chemical shifts were obained. A method based on NMR spectra was employed to determine the relative content of capsaicin to dihydrocapsaicin in natural capsaicins.
