Screening for antimicrobial activity against Gram positive and Gram negative microorganisms has been realised with Lippia turbinata, Satureja par6ifolia, Sambucus peru6iana, Verbena officinalis and Chenopodium gra6eolens. The total extracts of flavonoids of each plant were tested and four species studied showed antimicrobial activity., Satureja par6ifolia, Sambucus peru6iana, Verbena officinalis and Chenopodium gra6eolens.
