PHYTOCHEMICAL ANALYSIS AND ANTIBACTERIAL ACTIVITY OF DIFFERENT CITRUS FRUIT PEELSAbstract
Citrus fruit is a very rich source of Vitamin C, A, E, and flavonoids, alkaloids, and minerals. Citrus fruits are medicinal plants that present rutaceae family and include some fruits such as orange (Citrus sinensis), kinnow (Citrus reticulata), mosambi (Citrua ltmetta), grapefruit (Citrus maxima) lime, pomelo lemon. Antibacterial antiviral, antifungal activity of different solvent extracts (Acetone, ethanol, methanol, and distilled water) prepared by soxhlet extractor and aqueous solvent from three citrus fruit peel orange, kinnow, mosambi (Citrus sinensis, Citrus reticulata, and Citrus limetta respectively) were screened against four pathogenic bacteria staphylococcus aureus, Bacillus subtilis, Escherichia coli and Salmonella typhi. The highest antibacterial activity was exhibited by the acetone peel and ethanol extract of Citrus reticulate peels. MICs were tested at concentrations ranging from 80-5.25 mg/mL as wells as their MBCs. The phytochemical analysis of the citrus peel extracts showed the presence of flavonoids, saponins, steroids, terpenoids, tannins and alkaloids.
