Abstract
Phytochemical screening and antioxidantactivity of wild mushrooms growingin tropical regions.Biodiversitas 22:4716-4721.This study aims to determine the presence of secondary metabolites which generally have bioactivity thatis antioxidant with phytochemical tests and antioxidant tests in Auricularia auricula, Schyzophyllum commune, Microporus xanthopus, and Trametesversicolorfungi that grow in the wild.Phytochemical analysis was carried out by testing color changesand modifications, while antioxidant tests were carried out by using a UV-Vis spectrophotometer and aDPPH solution (1,1-diphenyl-2-picrylhydrazyl).This research found thatedible wood fungus that grows,wild such asA. auricula,contains secondary metabolites, namely flavonoids, triterpenoids, saponins, and tannins, but doesnot contain steroids, alkaloids, carotenoids, orcoumarin, while S. communecontains secondary metabolites, namely flavonoids, steroids, tannins, and coumarin, but doesnot contain triterpenoids, alkaloids, carotenoids, orsaponins and non-edible wood fungus,such as M. xanthopus,contains secondary metabolites, namely,flavonoids, saponins, tannins, coumarin, and steroids,but doesnot contain triterpenoids, alkaloids, orcarotenoids, while T. versicolorcontains compounds,secondary metabolites,flavonoids, saponin, tannins, coumarin, and triterpenoids,but does not contain steroids, alkaloids, or carotenoids. The antioxidant test results are based on IC50calculations;it is known that the IC50value of A. auriculais 499.25 g/mL, while S. communeis 121.37 g/mL, M. xanthopusis 251.20 g/mL,and T. versicoloris493.04 g/mL. Based on the research results, edible and inedible wood mushroom extracts contain several phytochemicals and show potential for antioxidant activity.Keywords:Auricularia auricula, Microporus xanthopus,Schyzophyllum commune, Trametes versicolor, wood fungusINTRODUCTIONWood-rot fungi are wild fungi in nature that grow and live on logs with varyingdegrees of weathering, e.g.Microporus xanthopus, Auricularia auricula, Trametes versicolor,and Schyzophyllum commune. There are wood-rot fungithat can be consumed, such as A. auriculaand S. commune,whilenon-edible ones,such as M. xanthopusand T. versicolor,are a group of fungi that can break downcellulose and lignin so that wood becomes rotten, and the strength of its elastic fibers drops rapidly (Herliyana et al. 2011;Julian et al. 2019).Fungi or mushrooms are plantsthat are heterotrophic anddo not containchlorophyll, to meet their daily needs they take ready-made food substances from other organisms. Thesefungirequire a food source as asubstrate, an energy source (from the oxidation of carbon compounds), metabolic activity (for the growth and development of hyphae), and nutrients (Arbaain et al. 2019).Mushrooms contain various secondary metabolite compounds that contribute to various biological activity,apart from being a nutrient-rich food source and non-toxic drugs that have physiologicalbenefits (Mirfat et al. 2010). Metabolite compounds in plants are classified into two categories, namely,primary metabolites and secondary metabolites. Primary metabolites are formedlimited quantities and are used for the growth and life of organisms (Nofiani 2008). Secondary metabolites are compounds produced by organisms as protection against extreme environmental conditions or from predatory threats. Secondary metabolites are not used for growth butare transformed into primary metabolites understressful conditions (Nofiani 2008). Secondary metabolite compoundsare chemical compounds that generally have bioactivity ability to andfunction as protectorsof these plants from pests and diseases,for the plant itself or its environment.The benefitsof wood-rot fungus secondary metabolites have been reported by several researchers, including the secondary metabolite compounds of Auricularia auriculafungi that are anti-fungal (Triani et al. 2017), and potentially ananti-microbial herbal treatment forbacterial and fungal pathogens in humans (Oli et al. 2020),theyalso
