“…Considering the antimicrobial activity reported for this plant species, a preservative action from this extract, when incorporated to a gel, could be equally expected, as it has been reported for other species (Nostro, 2002;Manou, 1998).…”

Currently, microbial contamination is one of the major problems faced by the phytomedicine industry with respect to the quality of the raw materials. The objective of this study was to evaluate the effectiveness of a preservative system in a formulation with hydrogel containing hydroalcoholic extract of Schinus terebinthifolius Raddi, Anacardiaceae ("aroeira" or "Brazilian Peppertree"), through the challenge test. The extracts were prepared by maceration at a ratio of 1:10 plant/solvent in 40% alcohol. Gel samples were artificially contaminated with separate inocula of Aspergillus niger, Candida albicans, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and the number of viable microorganisms determined in triplicate by the "pour plate" method for counting colonies at 0, 24 and 48h, 7, 14, 21 and 28 days. The addition of the preservatives (methyl and propylparaben) in the "aroeira" gel proved to be effective against the studied species when the samples were evaluated using the challenge test. According to the criterion A of the European Pharmacopoeia, it was verified that the hydrogel product showed good conservation in a 28 days period.

1 H-and 13 C-NMR. The oil was dominated by C 3 oxygenated p-menthane derivatives: cis-isopulegone (75.2%), pulegone (6.9%), neoiso-isopulegol (6.0%) and trans-isopulegone (4.5%). The whole essential oil was tested against a variety of bacteria, both Gram-positive and Gram-negative, and two fungi; it exhibited remarkable activity against Escherichia coli and was active against Agrobacterium tumefasciens and Staphylococcus aureus and the phytopathogenic fungus Botrytis cinerea. It was ineffective against Streptococcus faecium, Streptococcus mutans and Candida albicans.

“…3,4 Plants from Lamiaceae family are well-known medicinal herbs that are widely used in pharmaceutical products and traditional medicine for the treatment of several pathologies. 5,6,7,8 However, their protective power against some strains of bacteria has not been deeply described. For further identification of substances with antimicrobial properties and streamlining their use, we evaluated in the present study the antibacterial activity of nine Moroccan plants from the Lamiaceae that was passed through an 80-mesh sieve.…”

Context:Plant from the Lamiaceae family are considered as dietary spices and medicinal herbs traditionally used in medicine for the treatment of several pathologies. Objective: Evaluation of the in vitro antibacterial activity of ethanol and aqueous extracts of nine Moroccan plants from the Lamiaceae family against six bacterial strains regularly implicated in toxiinfection. Method: The antibacterial activities of hot (HAE), cold (CAE) aqueous extracts and ethanolic extracts (EE) were evaluated using agar-well diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and IC 50 against six foodborne bacteria (Bacillus cereus, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica). Total phenolic and flavonoid contents were assessed as well. Results: In the present study, the ethanol extracts were rich in polyphenols, with middling values of flavonoids, and relatively poor in condensed tannins. The presence of saponins, essential oils, irroides, alkaloids, anthocyanins, and aldehydes was recorded. The effect of the extracts was directly bactericidal for B. cereus and L. monocytogenes; for the other strains, the MBC value was twice higher than that of MIC. However, the ethanol extract (EE) of O. majorana and T. satureioides showed the highest antibacterial activity. With the principal component analysis, it was demonstrated that the nine Lamiaceae family plants possess a powerful antibacterial effect, correlated with their phenolic content. Statistical analysis : Analysis of variance was performed by uni-varied ANOVA in the software SPSS 22 Fr. Conclusion : The active compounds were thermostable and soluble in ethanol and water. The antimicrobial activities of the plants extracts investigated may contribute to understand their involvement in traditional medicine against many microbial infections.
