Abstract:: Angulatin B , which is a sesquiterpene polyol ester , was studied using the NMR data analysis methodand was detected through 1D (1H , 13C NMR and DEPT) and 2D NMR (1H _ 1H COSY,HSQC, and HMBC)techniques . The results show that the 1H and 13C NMR spectra are completely analyzed and assigned and itsstructure in the literature is corrected by HMBC technique. This research provided NMR data analysis methodand evidences for the identification of sesquiterpene polyol esters.
