“…It has been recently demonstrated that Amomum tsao-ko extract exhibited a high biofilm inhibition when tested against S. typhimurium (51.96%), S. aureus (47.06%), and P. aeruginosa (45.28%) at 4 mg/mL. The same authors demonstrated that this extract can inhibit the violacein production (44.59%) and anti-swarming activity by 4 mg/mL extract on S. typhimurium and S. aureus [ 27 ].…”

To highlight the importance of the spices in the Mediterranean diet, the aim of the paper was to study the essential oil compositions and to clarify the potential differences in the biological activities of the three cardamom species. In the study, we compared the phytochemical profiles and biological activities of essential oils from Elettaria cardamomum, Aframomum corrorima and Amomum subulatum. The oils were analyzed using the GC and GC/MS techniques and were mainly constituted of the oxygenated monoterpenes which represents 71.4%, 63.0%, and 51.0% of all compounds detected in E. cardamomum, A. corrorima and A. subulatum essential oils, respectively, 1,8-cineole was the main common compound between the tree tested volatile oil. The essential oils showed significant antimicrobial activity against Gram-positive and Gram-negative microorganisms tested especially the fungal strains. The Ethiopian cardamom was the most active essential oil with fungal growth inhibition zone ranging from 12.67 to 34.33 mm, MICs values ranging from 0.048 to 0.19 mg/mL, and MBCs values from 0.19 to 1.75 mg/mL. The three tested essential oils and their main component (1,8-cineole) significantly increased the production of elastase and protease production, and motility in P. aeruginosa PAO1 in a dose dependent manner. In fact, at 10 mg/mL concentration, the three essential oils showed more than 50% of inhibition of elastolytic and proteolytic activities in P. aeruginosa PAO1. The same oils inhibited also the violacein production in C. violaceum strain. It was also noticed that at high concentrations, the A. corrorima essential oil significantly inhibited the germination of radish. A thorough knowledge of the biological and safety profiles of essential oils can produce applications of economic importance.

“…The presence of different structures of biomolecules in the volatile oils, allows a wider spectrum of bioactivity. Recently, it has been demonstrated that organic extracts from Amommum tsao-ko (Crevost et Lemarie) and Elettaria cardamomum exhibited anti-quorum sensing and antibiofilm activities [ 26 , 27 ].…”

“…The A. tsaoko ethanol extract exhibited anti-bacterial activity against A. baumannii and P. aeruginosa , whereas the aqueous extract did not. Most previous studies have examined the antibacterial activity of the extract or volatile oil of A. tsaoko , and although some results implied that they had antibacterial effects, this may be due to the larger concentrations used in these studies [ 28 , 29 ]. S. officinalis is a TCM, which be used to treat hemorrhoids, wounds, and ulcers in Eastern Asian countries [ 30 ].…”

“…A recent study evaluated the anti-QS activity of the A. tsaoko extract using Chromobacterium violaceum a biosensor strain. They showed that it exhibited anti-QS activity in a dose-dependent manner at a concentration range of 0.5–4 mg/mL [ 28 ]. Our study is the first one to use agr reporter strains to evaluate the quorum quenching activity of these extracts.…”

Background Multidrug-resistant pathogens are resistant to many antibiotics and associated with serious infections. Amomum tsaoko Crevost et Lemaire, Sanguisorba officinalis, Terminalia chebula Retz and Salvia miltiorrhiza Bge, are all used in Traditional Chinese Medicine (TCM) against multidrug-resistant pathogens, and the purpose of this study was to evaluate the antibacterial and anti-virulence activity of extracts derived from them. Methods The antibacterial activity of ethanol and aqueous extracts from these four plants was examined against several multi-drug resistant bacterial strains, and their anti-virulence potential (including quorum quenching activity, biofilm inhibition, and blocking production of virulence factor δ-toxin) was assessed against different S. aureus strains. The chemical composition of the most effective extract was determined by LC-FTMS. Results Only extracts from S. officinalis and A. tsaoko were shown to exhibit limited growth inhibition activity at a dose of 256 μg·mL-1. The S. officinalis ethanol extract, the ethanol and aqueous extract of A. tsaoko, and the aqueous extract of S. miltiorrhiza all demonstrated quorum quenching activity, but didn’t significantly inhibit bacterial growth. The ethanol extract of S. officinalis inhibited bacterial toxin production and biofilm formation at low concentrations. Chemical composition analysis of the most effective extract of S. officinalis showed that it mainly contained saponins. Conclusions The most active extract tested in this study was the ethanol root extract of S. officinalis. It inhibited δ-toxin production and biofilm formation at low concentrations and saponins may be its key active components. While the four plants showed no direct antibacterial effects, their anti-virulence properties may be key to fighting bacterial infections.

“…Bacterial quorum sensing is the cell to cell communication by producing the signaling molecules, autoinducers which confer the ability of controlling the gene expression through the detection of small signal molecules (Bai & Rai, 2011;Banerjee et al, 2017;Hentzer & Givskov, 2003;Jakobsen et al, 2012;Singh, Mishra, & Jha, 2017). Moreover, the quorum sensing regulates various bacterial behaviours, such as virulence factor production and motility (Harmsen, Yang, Pamp, & Tolker-Nielsen, 2010;Rahman, Lou, Yu, Wang, & Wang, 2017;Williams, 2007).…”

The transparent inhibition zone by p-coumaric acid (pCA) proving its inhibitory effect on quorum sensing. The treatment with a mixture of 0.1% Potassium Sorbate (PS)+0.01% pCA resulted in gradual inhibition of the viable counts of meat. In addition, the microbial counts of the samples treated with the mixture of pCA and PS were significantly lower than that treated with PS alone, which indicated that the effect of the mixture on bacteria and protein decomposition was stronger than that of PS alone, which can better delay the spoilage of meat. P-coumaric acid reduced the generation of biogenic amines, mitigating the spoilage of chilled pork meat. During sensory evaluation, pork meat treated with the mixture of pCA and PS scored higher than the control group. P-coumaric acid could be used to reduce the amount of PS, and the application of the mixture greatly enhanced the preservation efficiency and the quality of pork. Actividad inhibitoria del ácido p-cumárico en la percepción de cuórum y efecto potenciador del mismo en la conservación de la carne RESUMEN La zona de inhibición transparente del ácido p-cumárico (pCA) da cuenta de su efecto inhibitorio sobre la percepción de cuórum. El tratamiento de carne de cerdo con una mezcla de 0,1% de sorbato de potasio (PS) + 0,01% de pCA produjo una inhibición gradual de los recuentos viables de carne. Además, los recuentos microbianos de las muestras tratadas con la mezcla de pCA y PS fueron significativamente más bajos que el de aquellos tratados con PS solo. Esto indica que el efecto de la mezcla sobre la descomposición bacteriana y de proteínas fue más fuerte, retrasando más el deterioro de la carne que cuando se la trató con PS solo. El ácido p-cumárico redujo la generación de aminas biogénicas, mitigando el deterioro de la carne de cerdo refrigerada. En la evaluación sensorial, la carne de cerdo tratada con la mezcla de pCA y PS obtuvo una puntuación más alta que el grupo de control. En conclusión, el ácido p-cumárico puede usarse
