Nutritional, Hypoglycemic, and Haematinic Potentiality of Edible Mushroom Pleurotus tuber-regium (Rumph. ex Fr.) Singer

Abstract

Mycochemical composition, calorific value, the antioxidant activity of Pleurotus tuber-regium was analyzed and impact of P. tuber-regium extract on rat model especially glycemic, vitamins and blood parameters were explored to validate its medicinal importance. Mycochemical screening showed the presence of biochem-icals such as phenols, flavonoids, proteins, carbohydrates etc. The extract showed good antioxidant activity (33.62% total antioxidant activity equivalent to 21.30 µg ascorbic acid). The extract showed dose-dependent hypoglycaemic activity by significant decreased average blood glucose level at high dose (100.62 ± 1.04mg/dL) compare to control (124.40 ± 1.45 mg/dL), haematinic activity by el-evation of hemoglobin (14.75 ± 0.24 g/dL) at a high dose of extract compared to control (11.66 ± 0.21 g/dL). P. tuber-regium extract elevated vitamin B12 of rats at high dose of extract (449.60 ± 3.12 pg/mL) compared to control (420.00 ± 2.86pg/mL). P. tuber-regium extract showed a positive response to hypoglycemic, haematinic, and vitamin level of the body and posses high calorific value. Hence P. tuber-regium can be used as good fodder, medicinal and nutritional supplement.
