A Comparative Study of the Antibacterial Activity of Two Chenopodiaceae: Haloxylon scoparium (Pomel) and Traganum nudatum Del.

The present work is aimed mainly to investigate and compare the antibacterial activities of some extracts of the aerial parts of two Chenopodiaceae species : Haloxylon scoparium and Traganum nudatum against seven bacteria strains: three gram negative (Serratia marcescens ATCC 13880, Pseudomonas aeruginosa ATCC 10145 and Escherichia coli ATCC 25922) and four gram positive (Bacillus subtilis ATCC 6051, Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923 and Bacillus cereus ATCC 11778) using well diffusion method. The results revealed that both extracts exhibited a certain bioactivity against gram positive bacteria. H. scoparium extracts showed higher activity compared to T. nudatum. Moreover the butanol extract of H. scoparium and the methylene chloride extract of T. nudatum proved to be more noteworthy against Staphylococcus aureus with a maximum inhibition zone diameter of 22 mm and 19 mm respectively at 1000
