ANTIMICROBIAL ACTIVITY OF MEDICINAL PLANTS FROM THE HUAUTLA SIERRA BIOSPHERE RESERVE IN MORELOS (MÉXICO)

Abstract

Twenty-two extracts from nine Mexican
medicinal plants of eight different families
used for people neighbor to Huautla Sierra
Biosphere Reserve (REBIOSH) in different
infectious diseases were assayed in vitro to
determine their antibacterial activity against
Staphylococcus aureus, Streptococcus faecalis; Escherichia coli; Proteus mirabilis;
Salmonella typhi and the yeast Candida
albicans. Most plants showed antibacterial
activity, while two plants showed activity
against range 0.25 a 4 mg/mL almost one
microorganism used. The extracts showed
minimum inhibitory concentration (MIC)
against S. aureus and S. faecalis, represents
microorganisms Gram-positive were hexanic and acetonic extracts of Bursera copallifera and hexanic extract of B. grandifolia.
The ethanol extract of Lippia graveolens
showed a MIC value of 1 mg/mL against
yeast Candida albicans.
