Antimicrobial Activity of Fractions of Ethyl Acetate Extract of Cladosporium oxysporum, An Endophytic Fungus Derived from Alyxia reinwardtii

Dwi Hartanti, July Supriyanto, Noor Erma N Sugijanto


The endophytic fungi Cladosporium oxysporum was isolated from medicinal plants Alyxia reinwardtii. The antimicrobial activity of fractions of ethyl acetate extract and also antioxidant and antimicrobial activities of fraction 7 of ethyl acetate extract of (AR-7) were determined in this study. Antimicrobial activity was determined by TLC bioautography and disc diffusion methods. Antioxidant activity was determined by TLC-DPPH autography assay. The fractions of ethyl acetate extract of C. oxysporum at dose of 100 mg/ml were active as antimicrobial againstĀ  S. aureus, E. coli and C. albicans in disc diffusion method test. Fraction AR-7 was active as antioxidant in TLC-DPPH autography assay. Fraction AR-7 was active as antimicrobial against S. aureus, but was not active against another tested microoorganisms in TLC-bioautography
