| dc.description.abstract | Polyporus grammocephalus is a mushroom that is commonly found on fallen logs. This study determined the proximate and mycpchemical compositions and functional activities such as antioxidant, antibacterial, embryotoxic, teratogenic and cytotoxic effects of P. grammocephalus mycelia. Mycelia of P. grammocephalus contain 9 mycochemicals 9essential oils, alkaloids, coumarines, anthraquinones, phenols, flavonoids, steroids, tannins and terpenoids), 11.75% ash, 10.59% crude protein and 6.79% crude fiber. Ethanol extract exhibited radical scavenging activity with a mean of 64.57% and had a total phenolic content of 42.13 mg GAE/g. However no inhibitory activity against two bacterial pathigens was recorded. The mycelia extract showed embryotoxic and teratogenic effects in zebrafish. Aside from delayed growth, morphological abnormalities were also observed like C-shaped larvae with pericardial edema, C-shaped larvae with deformed yolk and bent tail as teratogenic effect. Based on the brine shrimp lethality assay, P. grammocephalus mycelia extract was non-toxic (LC50 value of 6569.328). | |
