PHYTOCHEMICAL SCREENING, ANTIOXIDANT PROPERTY AND ANTIBACTERIAL TESTING OF LEMON GRASS (Cymbopogon citratus), ALOE VERA (Aloe barbadensis) AND KUCHAI (Allium odorum)
Cymbopogon citratus, Aloe barbadensis and Allium odorum were assessed for their phytochemicals, antioxidant activity and antibacterial properties against Escherichia coli and Staphylococcus aureus. Phytochemical screening revealed that C. citratus, A. barbadensis and A. odorum had alkaloids, flavonoids, saponins, sterols, tannins, and terpenes. The antioxidant activity revealed that the extract of C. citrates had the highest radical scavenging activity (80.36%) and total phenolics (187.33 mg/g). Meanwhile, C. citratus, A. barbadensis and A. odorum exhibited bacterial inhibitory activity against E. coli and S. aureus. The phytochemicals, antioxidant activity, and the antibacterial properties of C. citratus, A. barbadensis and A. odorum shows that the three herbaceous plant have viable potential in fighting off causes of diseases such as free radicals and bacterial pathogens specifically, E. coli and S. aureus. This implication can be further explored for further utilization of the three plants.
