Antimicrobial Activity of the Olive Oil Flavor Compounds

Naturally Occurring Antifungal Agents and Their Modes of Action

“…The antimicrobial activity of a homologous series of 2E-alkenals characterized from plants has previously been reported Kubo et al, 1995a;Bisignano et al, 2001) and is generally similar to being described for the corresponding alkanols (Kubo et al, 1995b). Their MIC and MFC values against S. cerevisiae are listed in Table 2.…”

“…The amount of 2E-alkenals entering into the cytosol or lipid bilayer is dependent on the length of the alkyl chain. Hence, the length of the alkyl chain is associated with eliciting activity to a large extent Kubo et al, 1995a).…”

“…Subsequently, 2E-alkenals and alkanals were characterized from various edible plants such as the coriander Coriander sativum L. (Umbelliferae) (Kubo et al, 2004), the olive Olea europaea L. (Oleaceae) (Kubo et al, 1995a;Bisignano et al, 2001) and the cashew Anacardium occidentale (Anacardiaceae) (Muroi et al, 1993), and these aldehyde compounds exhibited broad antimicrobial activity (Table 1) (Kubo et al, 1995b). The maximum antimicrobial activity of 2E-alkenals is dependent on the balance of the hydrophobic alkyl (tail) chain length from the hydrophilic aldehyde group (head) (Kubo et al, 1995b and2003a).…”

Control of Toxigenic Fungi and Mycotoxins with Phytochemicals: Potentials and Challenges

“…Further, these are safe and effective in view of their systemic action and lack residual effect, easily biodegradable and exhibit stimulating effect on plant metabolism. Also, large number of earlier workers has reported antifungal properties of several plant species (Naganawa et al, 1996;Kubo et al, 1995). Efficacy of some plant phytochemicals against mycotoxin producing fungi suggests its possible use in minimizing the risk of mycotoxins as well as fungicides exposure.…”

Ancient Procedures for the High-Tech World: Health Benefits and Antimicrobial Compounds from the Mediterranean Empires

“…A study has shown that, contrary to most plant secondary metabolites, long chain saturated and unsaturated aldehydes from the olive fruit were more effective against fungi than against Grampositive bacteria [116]. The aliphatic aldehydes hexanal, nonanal, (E)-2-hexenal, (E)-2-heptenal, (E)-2-octenal and (E)-2-nonenal inhibited the growth of Tricophyton mentagrophytes and Microsporum canis at concentrations between 1.9 and 125 μg/mL, with the unsaturated aldehydes exhibiting the most broad spectrum of activity [117].…”
