Abstract:

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.

Key words: 13C NMR, Ganoderma, Ganoderma triterpenoids, chemical shift, chemical structure
