PHYTOCHEMICAL ANALYSES, ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF ACMELLA OLERACEA, A VARIETY GROWN IN MIZORAMAbstract
Acmella oleracea (L.) R.K. Jansen (family Asteraceae) is an interesting plant because of its wide range of medicinal and culinary uses. It has been traditionally used in the treatments of anemia, body ache, cancer, gastric ulcer and infections, gingivitis, gout, inflammations, laceration, malaria, stammering, and worm infection (helminthiasis). Different extracts of the plants were prepared, and the methanol extract showed the highest number of bioactive compounds, including carbohydrates, phytosterols, and tannins. The antioxidant activity was estimated from the rate of scavenging of the free radical, 2,2-diphenyl-1-picrylhydrazyl (DPPH). The plant extract showed similar concentration-dependent scavenging activity as that of butylated hydroxytoluene (BHT). The total antioxidant activity was estimated against ascorbic acid, and it showed a higher value than BHT. The methanol extract was treated with two Gram-negative bacteria Pseudomonas aeuroginosa and Escherichia coli, and two gram-positive bacteria Staphylococcus aureus and Bacillus subtilis. However, no antibacterial activity was observed. Nonetheless, the study provides important information on the basic pharmacological properties of the plant.
