title: Antimicrobial activity of flavonoids from leaves of Tagetes minuta.
abstract: The total extract and fractions with different solvents, obtained from leaves of Tagetes minuta, showed several degrees of antimicrobial activity against Gram positive and Gram negative microorganisms. The same fractions were inactive against Lactobacillus, Zymomonas and Saccharomices species. The major component of the extract: quercetagetin-7-arabinosyl-galactoside, showed significant antimicrobial activity on pathogen microorganisms tested. Correlation results were carried out using chloramphenicol as standard antibiotic.
