Nontargeted metabonomics analysis of Scorias spongiosa fruiting bodies at different growth stages

Summary

This study analyzed the chemical composition of Scorias spongiosa, an edible fungus, at different stages of growth using advanced laboratory techniques. Researchers found that the fungus contains beneficial compounds with antioxidant, anti-inflammatory, and other health-promoting properties. The study recommends harvesting the fungus at its earliest growth stage to preserve the most beneficial compounds for food and nutritional products.

Background

Scorias spongiosa is an edible fungus in the Capnodiaceae family rich in polysaccharides, amino acids, trace elements, and vitamins. The fungus forms fruiting bodies that change appearance at different growth stages. Understanding metabolite composition at various growth stages is important for determining optimal harvest timing and utilization.

Objective

To conduct nontargeted metabonomic analysis on Scorias spongiosa fruiting bodies at five different growth stages to identify differences in metabolites and related metabolic pathways during growth and development.

Results

The five growth stages were associated with 15 common metabolic pathways. Eleven bioactive substances were identified, with six (trehalose, spermidine, squalene, AICAR, protocatechuic acid, and stachyose) showing highest content at S1 stage. Metabolites related to sugar metabolism were enriched in pentose and gluconate interconversions, pentose phosphate pathway, and TCA cycle.

Conclusion

The S1 growth stage is recommended as the optimal harvest period to retain most bioactive substances in S. spongiosa fruiting bodies. The three main sugar metabolism pathways identified are related to polysaccharide content changes during fruiting body growth.
