Antibiotic Efficacy and Characterization of Mangrove Metabolites against UTI Microbes

摘要

In vitro antibacterial aptitude of Avicennia marina, A. marina var acutissima, Rhizophora mucronata, and R. annamalayana leaves were evaluated for urinary tract infective bacterial strains. A. marina var. acutissima and R. annamalayana methanolic extracts had diverse phytochemicals and demonstrated lower antibacterial activity at the concentrations of 100 to 250 ig.mLT1 and greater activity at 500 to 1,000 ig.mL~1. The minimum inhibitory concentration and minimum bactericidal concentration intensity of methanolic extracts were at 150 to 375 ig.mlr1. Alkaloids and genstine were noted in TLC fractionation, and their bioactivities were determined in bioautography analysis. Active functional groups OH alcoholic (hydrogen bond), C-H methylene, and C-O- aldehyde were present in both active guided fractions, but R_2C=CH_2 alkene and N-O nitraso groups were only in A. marina var. acutissima.
