    To discover new natural resources with biological effects, the chemical investigation of antioxidant and antimicrobial activities of extract's Chaetomium globosum isolated from roots of Urginea indica. Gas chromatography-mass spectrometry (GC-MS) analysis demonstrated the presence of the major chemical constituents present in the methanol extract (1,3-oxathiolane, 1,3cyclopentadiene, 5-(1-methylethylidene), 5,9-hexadecadienoic acid, methyl ester, decane), chloroform extract (acetic acid, diethoxy-, ethyl ester, 2,2-bis(ethylsulfonyl)propane, 3-methyl-2-(2-oxopropyl) furan), and hexane extract (3-hexanone, 4,4dimethyl, decane,2,6-dimethyldecane, decane, 2,4,6-trimethyl, decane, 2,4,6-trimethyl, 1-butanesulfinamide, 1,1,2,2,3,3,4,4,4nonafluoro-N-methyl, decane). The total compound identified (56.2%) in chloroform extract, (54.72%) in hexane extract, and (65%) in methanol extract. The antioxidant effects were performed using diphenylpicrylhydrazyl radical (DPPH). The results showed that the methanol extract showed significantly the highest anti-DPPH with an IC50 value of 37.61 +/- 1.37 mu g/mL, followed by chloroform and hexane extracts with IC50 values of 40.82 +/- 3.60 and 45.20 +/- 2.54 mu g/mL, respectively. The antifungal activity of extracts was evaluated against pathogens fungi including Fusarium oxysporum, Rosellinia necatrix, Cladosporium xanthochromaticum, and Sclerotinia sclerotiorum. Methanolic and chloroform extracts showed maximum inhibition against all test pathogens, while hexane extract showed minimum inhibition.
