| Abstract | ||
| The antibacterial activity studies of the Alcoholic , Flavonoides and glycoside extracts of the plant Brassica Nigra (Seeds) on Gram positive standard strain represented by Staphylococcus aureus and Gram negative standard strain represented by Escherichia Coli and Pseudomonas aeruginosa, also antibacterial activity studied on (100) isolated included Gram positive strain represented by S. aureus and Gram negative standard strain represented by E. Coli , Ps. aeruginosa and Proteus vulgaries. The results show that the flavonoid and glycoside extract of the plant Brassica Nigra had antimicrobial activity against Gram positive and Gram negative strain in this studies, but alcoholic extract of the plant Brassica Nigra was no antibacterial activity on all strain. The minimum inhibitory concentration (MIC) was determined. The results showed that the (MIC) of the flavonoid and glycoside extract on Gram positive standard strains S. aureus was (2, 0.5 ) µg/ml respectively, and Gram negative standard strain represented by E. Coli was (0.25, 0.125) µg/ml respectively and Ps. aeruginosa was (1,0.25) µg/ml respectively. The celluler cytotoxicity of flavonoide and glycoside extract was determined by observation of its effect on RBCs. The results found that all these extracts didn't show any cytotoxicity on the concentration (200) mg/ml. | ||
