ANTIFUNGAL ACTIVITIES OF PANGIUM EDULE REINW SEED EXTRACTS INHIBIT THE GROWTH OF ASPERGILLUS FLAVUS, PRODUCER OF AFLATOXINS, THROUGH THE IN-VITRO TESTAbstract
Aspergillus flavus is a famous fungus that produces aflatoxins. Aflatoxins are the most well known toxic and carcinogenic chemical prominent produced in nature. The fungus and aflatoxins are the main concern of the corn consumer. Pangi (Pangium edule Reinw) is a potential native plant to reduce infestation of the fungus A. flavus to prevent fungal contamination of food or feed. The research was undertaken to assess the antifungal activity of the P. edule Reinw extracts of seed against fungus A. flavus. Higher concentration is shown as the best concentration to suppress the growth of the A. flavus both mycelial growth and emerging new colony. The concentration of the 15% effectively and consistently inhibits A. flavus than other treatments. The lower concentration of 0.5%, 0.75%, 1% showed not significantly different over the control. Another higher concentration of the 5% showed that there is no inhibition of the fungus growth. However, the concentration of the 10% indicates also as a good treatment to suppress the fungus growth. Colony appearance after 144 h after inoculation showed that concentration of 15% remains white is different than control that shows mostly green colony. This study exhibits the efficacy of formulated Pangium edule Reinw seed in inhibiting A. flavus growth.
