%X The fruiting bodies of higher Ganoderma are well-known traditional Chinese medicines. The results of many previous studies have indicated that Ganoderma triterpenoids found in Ganoderma sp. are the main bioactive components. In recent years, a great number of novel triterpenoids with unique chemical structures has been isolated from Ganoderma. ^13C NMR is a powerful tool to determine the structure of Ganoderma triterpenoids. In this paper, a meta-analysis was performed on previously reported ^13C NMR chemical shifts of triterpenoids and another substances isolated from Ganoderma and on their assignment. The characteristics of and interpretation rules for the ^13C NMR spectra of these compounds were discussed. The results obtained in this study should be useful for future studies investigating the chemical structures, configuration and conformation of Ganoderma triterpenoids.
