EFFECTS OF SUBSTRATES ON THE PROXIMATE AND PHYTOCHEMICAL ANALYSIS OF Pleurotus tuber regium(Fries) Singer
semanticscholar(2017)
Abstract
The effect of sclerotium and three different substrates on the proximate and phytochemical composition of Pleurotus tuberregium (Fries) Singer was investigated. The result showed that Pleurotus tuberregium grown from the three substrate namely : cassava peel, oil palm husk and banana peel with its sclerotium is nutricious. The highest values of moisture content and protein, were in cassava peel (7.90%) and oil palm (30.49%) while sclerotium fruiting bodies had the highest values for ash (3.76%) and crude fibre (5.16%) and sclerotium after fruiting bodies had the highest values for crude fiber (6.73%)and carbohydrate (64.33%) while the lowest values in moisture was in oil palm (5.92%), in protein and ash, lowest values were in sclerotium after fruiting bodies (18.66%), (1.59%) respectively, sclerotium after fruiting body had lowest values in protein (18.66%) and ash (1.59%). Banana leaves has lowest value in fat (0.81%), sclerotium fruiting bodies had lowest value in crude fiber (2.47%) and oil palm husk had lowest value in carbohydrate (52.43%). There were significant differences on all the samples. Saponins, tannins, steroids, flavonoids, glycoside, phenols were present in all the samples while alkaloid and phlobatannins were absent in all the samples. This work shows that Pleurotus tuberregium can supply rich nutrient that can support good functioning of both human and animal system .
