Antifungal activity of Cinnamomum iners bark extract against Schizophyllum commune

Plants contain various bioactive compounds that benefit humans and the environment, such as antimicrobial, antiplasmodial, cytotoxic, amylase inhibitor, antinociceptive, anti-inflammatory, biopesticide, and antifungal. This study aims to analyze the antifungal activity of teja lawang (Cinnamomum iners) bark extract against the wood-decaying fungi Schizophyllum commune. The bark powder samples with a 40-60 mesh size came from three trees with a diameter of approximately 30 cm growing at the Forest Education of Hasanuddin University. The powder was extracted with methanol and acetone, followed by successive fractionation with n-hexane, ethyl acetate, and water. The effectiveness of antifungal activity was determined based on the Antifungal Activity (AFA) value, with testing patterned in a completely randomized design for six treatments at two concentrations, namely 50 ppm and 100 ppm. The results showed that acetone and methanol extract yields were 6.39% and 3.52%, respectively. Adding extract and its fractions to PDA media can inhibit the growth of S. commune with an AFA index ranging from 64% to 100%, categorized as strong to very strong. The C. iners bark extract has significant potential as a biocontrol agent for the fungus S. commune.
