Triterpene antioxidants from ganoderma lucidum

Area of Science:

• Pharmacology
• Natural Products Chemistry
• Biochemistry

Background:

• Oxidative stress is implicated in various pathologies.
• Natural products like Ganoderma lucidum are explored for therapeutic potential.
• Antioxidant compounds can mitigate cellular damage.

Purpose of the Study:

• To investigate the antioxidant properties of Ganoderma lucidum.
• To isolate and identify active compounds responsible for antioxidant effects.
• To evaluate the efficacy of different Ganoderma lucidum fractions.

Main Methods:

• Bioassay-guided isolation of active compounds.
• In vitro antioxidant assays, including erythrocyte membrane oxidation and lipid peroxidation.
• Chemical characterization of isolated compounds.

Main Results:

• Ganoderma lucidum extracts and fractions displayed dose-dependent antioxidant activity.
• The terpene fraction exhibited superior antioxidant effects compared to the aqueous extract and polysaccharide fraction.
• Key compounds identified in the terpene fraction include ganoderic acids A, B, C, D, lucidenic acid B, and ganodermanontriol.

Conclusions:

• Ganoderma lucidum possesses potent antioxidant capabilities.
• Terpene compounds, particularly ganoderic acids, are major contributors to its antioxidant activity.
• This study supports the use of Ganoderma lucidum as a source of natural antioxidants.
