Pleurotus tuber- regium (Rumph. ex Fr.) Singer a potent source of antioxidant

Mushrooms have been used as traditional source of nutritional food and medicinal suppliments. P. tuber-regium has been well known edible fungi and posses bioactive mycochemicals such as flavonoids, phenols, alkaloids, glycosides, proteis, fattyacids etc. and possess good antioxidant activity. Among estimated biochemicals alkaloid was found in high quantity (28.14 ± 0.32mg/100g) and tannin in low quantity (2.74 ± 0.26mg/100g). The mushrooms extract also posses good antioxidant potentiality. Estimated freeradical scavenging cativity was 8.98±1.02%, hydroxy radical scavenging activity was 10.85±0.73% and total antioxidant capacity of the crude extract was 21.50±1.3% at 100µg/100mL concentration of extract
