We conducted experiments on the different development stage of Momoridica charantia fruit and different types of solvent, water and 70% EtOH, affect the content of total polyphenol and flavonoid and its antimicrobial activity. The total polyphenol and flavonoid of each extracted solution from Momordica charantia fruit was determinated by colorimetric method. The antibacterial and antifungal activity was studied by paper disc diffusion method and inhibition rate with potato dextrose agar (PDA) respectively. The result, total polyphenol was determinated higher content to 70% EtOH extracted unripe fruit, and 70% EtOH extracted seed hull. Flavonoid concentration was desterminated the highest content to water extracted ripe fruit. The results of the antibacterial activities was showed that water extracted unripe fruit had 43% antibacterial activity against Neisseria gonorrheoae KCTC 2746. While all extracted solution was showed the highest antifungal activity against balck rot's disease. 10 mg/ml of extracted solutions were particularly exhibited an average 40% and over anti-fungal activity. Therefore, the fruit extracts of Momordica charantia possess the effect of biological prevention on the black rot's disease of plant.
