摘要/Abstract

摘要： 用一维¹H NMR谱、¹H-¹H COSY谱和一维¹³C NMR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,采用¹H NMR谱测定天然辣椒碱中辣椒碱和二氢辣椒碱的相对含量.

关键词: ¹H和¹³C NMR谱, 辣椒碱, 二氢辣椒碱

Abstract: Capsaicin, dihydrocapsaicin and their mixtures were studied by 1D ¹H NMR spectra, ¹H-¹H COSY spectra, 1D ¹³C NMR spectra and DEPT spectra.The ¹H and ¹³C chemical shifts were obained.A method based on NMR spectra was employed to determine the relative content of capsaicin to dihy drocapsaicin in natural capsaicins.

Key words: ¹H NMR spectra, ¹³C NMR spectra, Capsaicin, Dihydrocapsaicin
