Comparison of Different Extraction Solvents for Characterization of Antioxidant Potential and Polyphenolic Composition in Boletus edulis and Cantharellus cibarius Mushrooms from Romania

Summary

This research compared how well four different liquids extract beneficial compounds from two popular edible mushrooms: porcini (Boletus edulis) and chanterelle (Cantharellus cibarius). The study found that a simple acidic water solution was the best at pulling out healthy antioxidant compounds and polyphenols from these mushrooms. These antioxidants help protect cells from damage, making them potentially beneficial for health.

Background

Edible mushrooms are known for their nutritional benefits and bioactive compounds including polyphenols with antioxidant properties. The extraction efficiency of bioactive compounds depends on the extraction conditions and solvents used. This study investigates how different extractants affect polyphenol and antioxidant properties in two widely consumed wild mushrooms.

Objective

To evaluate the effects of four different extraction solvents on total phenolic content, total flavonoid content, and antioxidant capacity of Boletus edulis and Cantharellus cibarius mushrooms, and to identify individual polyphenolic compounds in the extracts.

Results

Acidic water extracted the highest amount of polyphenolic compounds from both mushroom types, with the strongest antioxidant activity. A very strong positive correlation was found between total phenolic content and antioxidant capacity, but no correlation between flavonoid content and antioxidant activity. Seventeen compounds were identified in B. edulis and fourteen in C. cibarius, predominantly phenolic acids.

Conclusion

Acidic water is recommended as the preferred solvent for extracting bioactive polyphenolic compounds from B. edulis and C. cibarius mushrooms, as it provides superior extraction efficiency and is a green solvent suitable for food industry applications.
