Phytochemical Screening and Antibacterial Activity of Flower, Stem, and Tuber of Polianthes tuberosa L. Against Acne-Inducing Bacteria

Anti-MRSA activity of Pollianthes tuberosa leaf extracts

“…Studies reported that chloroform, n-hexane, water and carbon tetrachloride from concentrate methanol extract where exhibited antagonistic activity against Gram negative pathogens such as Vibrio mimicus, Shigella dysenteriae, Shigella boydii, Escherichia coli, Pseudomonas aerugonisa, Salmonella typhi, S. paratyphi, Vibrio parahemolyticus and Gram positive pathogens like Bacillus subtilis, S. auerus, Sarcina lutea, B. megaterium, B. cereus at 400 µg dose/disc with 9-11 mm resistance range. The methanol extract obtained from the dried flower was active against Proteus mirabilis with inhibition of 16 ± 1 mm at 60 µg/mL dose and 40 µg/mL dose, it was active against E. coli with 12.3 ± 1.5 mm inhibition ( (Setiani et al, 2020). The present study aimed to screen the antagonistic activity of crude extracts obtained from P. tuberosa against selected bacterial pathogens.…”
