Background: Local communities near La Malinche National Park have traditionally consumed wild edible mushrooms as an alternative seasonal food during the rainy season.
Objective: Evaluate the chemical composition and antioxidant activity of Hygrophoropsis aurantiaca and Hypomyces macrosporus collected in La Malinche National Park, Mexico.
Methods: A proximate chemical analysis was carried out to determine moisture, fat, reducing sugars, total dietary fiber, ash, crude protein, and fatty acid profile. Chemical analysis was performed on some mycochemical metabolites: total phenolic compounds, total flavonoids, and total triterpenes. The antioxidant activity against the DPPH and ABTS radicals was evaluated.
Results and conclusions: Hygrophoropsis aurantiaca and Hypomyces macrosporus, were found to contain relevant macronutrients and mycochemical compounds. In H. aurantiaca, crude protein ranged from 11.2-12.5%, fibre 21.4-23.1%, and triterpenes 25.4-28.6 mg UAE/g, while antioxidant activity showed IC₅₀ values of 1.20 ± 0.22 mg/mL. In H. macrosporus, protein contents were lower (8.7-9.5%), fiber 18.9-20.1%, and triterpene content was 6.3-7.1 mg UAE/g, with antioxidant activity of 5.78 ± 0.03 μmol ET/g. These results demonstrate that both wild edible mushrooms are valuable sources of nutritional and mycochemical components.
