Study on the Phytochemical Constituents in Essential oil of Pandanus amaryllifolious Roxb. Leaves and their Anti-bacterial Efficacy Ae Mar Aye Aye Mar Pwint Phyu Thin Moh Moh Zin The study was conducted to evaluate the phytochemicals and antibacterial efficacy of essential oil of Pandanus amaryllifolius leaves against various Gram-positive and Gram-negative bacterial. The phytochemicals of essential oil of P. amaryllifolius leaves were analyzed by using GC-MS, while the mass spectra of the compounds found in the essential oil was confirmed by comparison of their Kováts retention indices relative to C8-C22 n-alkanes. The gas chromatography–mass spectroscopy (GC-MS) analysis of P. amaryllifolius leaves essential oil showed the presence of 54 compounds were identified, representing 98.28 % of the total oil composition. It was observed that phytol in essential oils was the major component, with the highest concentration in oil (21.35%), followed by -thujaplicin (18.64%), dodecanol (12.55%), n-tetradecanol (8.93%), benzyl acetate (8.08%). The finding of present study revealed that the essential oil of pandanus leaves demonstrate the presence of potential extractive active substances and their antibacterial potential. The essential oil had the greatest antibacterial activity against all Gram-negative bacteria. The essential oil had the largest inhibition zones against E. coli and M. luteus, measured at 15.3, 10.7, respectively. The lowest MIC value (31.2 μg/mL) was observed for the drugs, while the essential oil showed higher MIC values at concentrations of 31.25 μg/mL for E. coli and M. luteus, 62.5 μg/mL for Ps. aeruginosa and 125 μg/mL for S. aureus, respectively. 2019 http://hdl.handle.net/20.500.12678/0000000477 https://meral.edu.mm/records/477
