Constituents from solid-cultured Antrodia camphorata

Area of Science:

• Mycology
• Natural Product Chemistry
• Pharmacology

Background:

• Antrodia camphorata is a highly valued mushroom in Taiwan, traditionally used for health benefits.
• Its rich phytochemical profile makes it a target for scientific investigation.
• Previous research has hinted at its potential medicinal properties.

Purpose of the Study:

• To isolate and characterize novel and known compounds from Antrodia camphorata.
• To evaluate the cytotoxic effects of isolated compounds on HepG2 cells.

Main Methods:

• Phytochemical analysis involving isolation and purification techniques.
• Structure elucidation using 2D NMR (COSY, HMBC, HSQC, NOESY) and HRMS.
• Cytotoxicity screening using HepG2 cell lines at a concentration of 50 μg/mL.

Main Results:

• A new naphthalenecarboxaldehyde (1) was isolated and identified.
• Seven known compounds (nerolidol, cadinol, herbarulide, etc.) were identified for the first time in this mushroom.
• Compounds 2,3-dimethoxy-5-methyl-p-benzoquinone (7) and β-sitosterol (8) demonstrated significant toxicity to HepG2 cells.

Conclusions:

• The study successfully identified a novel compound and several known compounds from Antrodia camphorata.
• Specific compounds, 7 and 8, exhibit cytotoxic activity against HepG2 cells, suggesting potential for further pharmacological research.
