[Comparative study on triterpenes in different Ganoderma species]

Area of Science:

• Mycology and Phytochemistry

Background:

• Ganoderma species are widely used in traditional medicine.
• Triterpenes are key bioactive compounds in Ganoderma, responsible for many health benefits.
• Understanding triterpene content variability is crucial for quality control and therapeutic efficacy.

Purpose of the Study:

• To analyze and compare the triterpene profiles of various Ganoderma products.
• To identify Ganoderma sources with optimal triterpene content for medicinal use.

Main Methods:

• High-Performance Liquid Chromatography (HPLC) was employed to quantify triterpene levels.
• Analysis included fermented mycelia, fruiting bodies at different growth stages, spores, and different Ganoderma species.

Main Results:

• Seven-day fermented Ganoderma mycelia exhibited low triterpene content.
• Triterpene levels in fruiting bodies remained relatively constant across different growth stages.
• Ganoderma spores contained lower triterpene concentrations compared to fruiting bodies.
• Ganoderma atrum was found to have significantly lower triterpene levels among the tested species.

Conclusions:

• Fermented mycelia and spores are not ideal sources for high triterpene content in Ganoderma products.
• Fruiting bodies offer a more consistent source of triterpenes, though Ganoderma atrum is an exception.
• HPLC analysis provides a reliable method for assessing triterpene content and guiding Ganoderma product selection.
