The Pink Oyster Mushroom, Pleurotus djamor (Agaricomycetes): A Potent Antioxidant and Hypoglycemic Agent

The present investigation aimed to study the physicochemical properties, nutritional indices, antioxidant properties, and hypoglycemic effects of dried pink oyster mushroom (Pleurotus djamor) powder. The yield of dried mushroom powder was 8.54%, the oil absorption capacity was 3.34 mL/g, and the swelling index was 0.33 mL/g. A qualitative analysis of mycoconstituents revealed that tannins, flavonoids, terpenoids, cardiac glycosides, and saponins were present in P. djamor. Free radical scavenging activity on 2,2-diphenyl-1-picrylhydrazyl was 6.22%. Hypoglycemic testing revealed that the highest (P < 0.05) glucose consumption by poultry hepatocytes was at 2 mL of mushroom extract at 100 mg% glucose exposures, followed by 200 and 150 mg% exposures. These results indicated that P. djamor powder can be used to lower the risk of lifestyle diseases, including diabetes, and to alleviate malnutrition.
