Nortriterpenoids from the Fruiting Bodies of the Mushroom 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 . . In this study, fifteen nortriterpenoids including six new nortriterpenoids (-) and nine known analogs (-), were separated and purified from the fruiting bodies of . . New compounds were identified as lucidone I (), lucidone J (), lucidone K (), lucidone I (), ganosineniol B (), and ganosineniol C (), 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 (), lucidone B (), lucidone H (), lucidone E (), lucidone F (), lucidone D (), lucidone C (), ganoderense F (), and ganosineniol A (), by comparing their spectroscopic data with those reported in the literature. Compounds , , and - were examined for -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 -glucosidase inhibitory activity.
