BackgroundThe aim of the present work was to evaluate the antibacterial effect of 3,4-DHPEA-EA (methyl-4-(2-(3,4-dihydroxyphenethoxy)-2-oxoethyl)-3-formyl-2-methyl-3,4-dihydro-2H-pyran-5-carboxylate), a derivate of oleuropein, against a range of Gram-positive bacteria, including ATCC strains, food and clinical isolates.MethodsThe minimum inhibitory concentrations (MICs) of 3,4-DHPEA-EA were determined by the broth microdilution method and the Bioscreen C.Results3,4-DHPEA-EA was effective… 
In Vitro Efficacy of Crataegus oxycantha L. (Hawthorn) and Its Major Components against ATCC and Clinical Strains of Ureaplasma urealyticum
TLDR
It is demonstrated that flavonoids present in Crataegus oxycantha are effective against clinical isolates of U. urealyticum and could be used in combination with antibiotics in order to combat resistance.
Compounds from Olea europaea and Pistacia lentiscus inhibit oral microbial growth
TLDR
Overall, maslinic acid and oleanolic acid exerted the most significant inhibitory activity against the tested oral pathogens, especially streptococci and anaerobic oral microorganisms.
Phenolic compounds of Tagetes lucida Cav. with antibacterial effect due to membrane damage
TLDR
The sytox and comet tests showed an antibacterial action of the extract on the bacterial membrane and DNA of this bacterial strain, and the bioautography revealed that the phenolic compounds could act synergistically.
Biochemical Characterization of Clinical Strains of Staphylococcus spp. and Their Sensitivity to Polyphenols-Rich Extracts from Pistachio (Pistacia vera L.)
TLDR
The antimicrobial potential of pistachios could be used to identify novel treatments for S. aureus skin infections and to characterized a number of clinical strains of Staphylococcus spp.
In Vitro Antimicrobial Activity and Effect on Biofilm Production of a White Grape Juice (Vitis vinifera) Extract
TLDR
WGJe exerted both bacteriostatic and bactericidal activity in vitro against a range of Gram-positive and Gram-negative bacteria, yeasts, and the fungus Aspergillus niger to develop novel strategies for the treatment of skin infections and against potential respiratory pathogens.
Antibacterial Potential by Rupture Membrane and Antioxidant Capacity of Purified Phenolic Fractions of Persea americana Leaf Extract
TLDR
The most susceptible strain to the treatment with the extract was S. aureus, and in this strain, the bacterial membrane damage induced by the extract and fractions was evidenced by light fluorescence microscopy and the extract had better antioxidant action than each fraction.
Anti‐infective potential of Citrus bergamia Risso et Poiteau (bergamot) derivatives: a systematic review
TLDR
A systematic review on the anti‐infective properties of bergamot derivatives that highlight the activity of bERGamot essential oil against bacteria, mycetes and larvae, as well as the anti-Helicobacter pylori effect of b Bergamot juice and the antimicrobial properties of extracts from bergAMot peel are presented.

In vitro antibacterial activity of some aliphatic aldehydes from Olea europaea L.
TLDR
The saturated aldehydes characterized in the present study do not exhibit significant antibacterial activity, while the alpha,beta-unsaturated aldeHydes have a broad antimicrobial spectrum and show similar activity against Gram-positive and Gram-negative microorganisms.
Synergism and postantibiotic effect of tobramycin and Melaleuca alternifolia (tea tree) oil against Staphylococcus aureus and Escherichia coli.
In vitro evaluation of secoiridoid glucosides from the fruits of Ligustrum lucidum as antiviral agents.
TLDR
Results showed that none of the glucosides had any significant activity against HSV-1 and Flu A, and documented that the anti-oxidative potency of these secoiriodoid glucoside was not directly related to their antiviral effects.
Antimicrobial activity of commercial Olea europaea (olive) leaf extract.
Phenolic compounds and antimicrobial activity of olive (Olea europaea L. Cv. Cobrançosa) leaves.
TLDR
At low concentrations olive leaves extracts showed an unusual combined antibacterial and antifungal action, which suggest their great potential as nutraceuticals, particularly as a source of phenolic compounds.
The olive compound 4-hydroxytyrosol inactivates Staphylococcus aureus bacteria and Staphylococcal Enterotoxin A (SEA).
TLDR
It is suggested that food-compatible and safe antitoxin olive compounds can be used to reduce both pathogens and toxins produced by the pathogens in foods.
Main antimicrobial compounds in table olives.
TLDR
It was found that the dialdehydic form of decarboxymethyl elenolic acid, identified for the first time in table olives, and an isomer of oleoside 11-methyl ester were also effective against Lactobacillus pentosus and can, therefore, contribute to the antimicrobial activity of olive brines.
In vitro antimicrobial activity of pistachio (Pistacia vera L.) polyphenols.
TLDR
The bactericidal activity of pistachio extracts could be used to help control the growth of some microorganisms in foods to improve safety and may find application as a topical treatment for S. aureus.
Bactericidal activity of glutaraldehyde-like compounds from olive products.
TLDR
It is proposed that the bactericidal activity of the main olive antimicrobials is primarily due to their dialdehydic structure, which is similar to that of the commercial biocides GTA and OPA.
Absorption and metabolism of olive oil secoiridoids in the small intestine.
TLDR
It is suggested that the reduced and glucuronidated forms represent novel physiological metabolites of the secoiridoids that should be pursued in vivo and investigated for their biological activity.
