Abstract

Ganoderma resinaceum is usually used as ethnomedicine for immune-regulation, hyperglycemia, and liver disease. To date, only a few chemical constituents have been reported from G. resinaceum. In this study, fifteen nortriterpenoids including six new nortriterpenoids (1-6) and nine known analogs (7-15), were separated and purified from the fruiting bodies of G. resinaceum. New compounds were identified as lucidone I (1), lucidone J (2), lucidone K (3), lucidone I (4), ganosineniol B (5), and ganosineniol C (6), based on analysis of extensive spectroscopic data (high resolution mass spectrometry (HRMS), nuclear magnetic resonance (NMR), infrared (IR), and ultraviolet (UV)). The known compounds were assigned as lucidone A (7), lucidone B (8), lucidone H (9), lucidone E (10), lucidone F (11), lucidone D (12), lucidone C (13), ganoderense F (14), and ganosineniol A (15), by comparing their spectroscopic data with those reported in the literature. Compounds 3, 4, and 7-13 were examined for α-glucosidase inhibitory activity and display no significant activity, but the finding may support that the side chain of ganoderma triterpenoids played an important role in α-glucosidase inhibitory activity.
