Summary
This research examined the beneficial compounds and properties of a Brazilian edible mushroom called Pleurotus ostreatoroseus. Scientists found that extracts from both the mushroom caps and laboratory-grown fungal cells contain various healthy compounds with antioxidant, anti-inflammatory, and antimicrobial properties. The study shows this mushroom could have potential health benefits while being safe for consumption.
Impacts on everyday life:
• Identifies a new natural source of beneficial compounds for potential food supplements or medicines
• Validates the traditional use of this edible mushroom in Brazilian cuisine
• Demonstrates safe ways to produce beneficial mushroom compounds through laboratory cultivation
• Provides scientific support for developing new natural antioxidant and antimicrobial products
• Opens possibilities for sustainable production of bioactive compounds through mushroom cultivation
Background
Pleurotus ostreatoroseus is a Brazilian edible mushroom whose chemical characterization and bioactivity remain underexplored. Understanding its bioactive compounds and properties is important for potential therapeutic applications.
Objective
To compare the hydrophilic and lipophilic compounds as well as the antioxidant, anti-inflammatory and antimicrobial activities of formulations prepared from P. ostreatoroseus fruiting bodies and submerged culture mycelia.
Results
The formulations contained at least five free sugars, four organic acids, four phenolic compounds and two tocopherols. The fruiting body-based formulation showed superior reducing power, DPPH scavenging activity, β-carotene bleaching inhibition and lipid peroxidation inhibition compared to the mycelium-based preparation. It also demonstrated higher anti-inflammatory and antimicrobial activities. Neither formulation showed hepatotoxicity in porcine liver primary cells.
Conclusion
The bioactive properties of P. ostreatoroseus formulations, particularly from fruiting bodies, can be attributed to their phenolic acids, organic acids and tocopherols content. The absence of hepatotoxicity and presence of multiple beneficial compounds suggests potential for therapeutic applications.
