Investigation on Potentiality of 2h-Furo [2,3-H]-1-Benzopyran-2-One from Psoralea corylifolia L. Seeds against Gram Negative Human Bacteria

The bioactive molecule 2H-Furo[2,3-H] has antibacterial action. At concentrations of 100-1000ppm, -1-benzopyran-2-one was tested against five human bacterial species: Klebsiella pneumoniae, Vibrio cholerae, Escherichia coli, Shigella dysenteriae, and Salmonella typhi. K. pneumonia showed 32.0mm inhibition at 700mm concentration, the highest
