Abstract


There are diverse beneficial health effect of mushrooms to humans, such as food, drugs and medicines, and it is cultivated worldwide on almost all agricultural and agro industrial residues. This work examined the quantities of phytochemicals present in Pleurotus ostreatus  that was cultivated on compost and vermicompost  prepared from wood dust substrates of P. angolensis with organic waste (cow dung, goat dung, sheep dung and poultry droppings)  mixed at ratio 9:1 using stock pile method for a period of 70 days. Samples of harvested mushroom were analysed quantitatively using the standard method described by Nwosu (2011) for phytates, saponin, tannin, oxalates and alkaloids. Comparing the amount of phytochemicals in compost and vermicompost, the result showed that alkaloids have the highest amount of 0.27% in mushroom cultivated on composting substrate of the wood dust with cow dung compared to the least of 0.02% of tannins in mushroom cultivated on all the substrate mix. There is no significant difference in the quantities of these chemicals in P. ostreatus cultivated on both compost and vermicompost substrates at P<0.05. Composting and vermicomposting of cultivating substrates reduced the quantities of all the phytochemicals in mushroom and are safe for dietary intake.
