“…However, researchers have indicated that this chemical compound imperceptibly contributed to any antibacterial effect at tested concentrations against Enterococcus faecalis , S. mutans , and Lactobacillus rhamnosus [50] . Nonetheless, it has been observed that when β‐myrcene is combined with other constituents, it exhibits synergistic effects that contribute to the overall antibacterial activity [51] . Interestingly, another major monoterpenoid present in this essential oil of C. mangga , namely, β‐pinene, has been reported to possess bacteriostatic activity.…”

“…[50] Nonetheless, it has been observed that when β-myrcene is combined with other constituents, it exhibits synergistic effects that contribute to the overall antibacterial activity. [51] Interestingly, another major monoterpenoid present in this essential oil of C. mangga, namely, βpinene, has been reported to possess bacteriostatic activity. This suggests that β-pinene may play a significant role in contributing to the antibacterial properties of the essential oil.…”

Essential oils have been recognised for their potential benefits in oral care. The aim of this study was to evaluate the antibacterial and antiproliferative activity of essential oils derived from four Zingiberaceae species. A combination of GC/MS and GC‐FID was employed to analyse these essential oils. The results showed that β‐myrcene (79.77%) followed by ethyl‐cinnamate (40.14%), β‐curcumene (34.90%), and alloaromadendrene (25.15%) as the primary constituents of Curcuma mangga, Curcuma xanthorrhiza, Kaempferia galanga and Curcuma aeruginosa, respectively. The Zingiberaceae oils were tested for their antibacterial activity against oral bacteria using the disc diffusion test. Curcuma xanthorrhiza oil showed the largest inhibition zones against Streptococcus mitis (19.50 ± 2.22 mm) and Streptococcus sanguinis (15.04 ± 3.05 mm). Similarly, Curcuma mangga oil exhibited significant antibacterial activity against Streptococcus mutans (12.55 ± 0.45 mm) and mixed oral bacteria (15.03 ± 3.82 mm). Furthermore, the MTT viability assay revealed moderate inhibitory activity of these essential oils against H103 and ORL‐204 oral cancer cells. The study findings demonstrate that Curcuma xanthorrhiza and Curcuma mangga essential oils have potent antibacterial properties, suggesting their potential use as natural alternatives to synthetic antibacterial agents in oral care products. However, further investigations are necessary to fully explore their therapeutic applications.

“…Again, the individual components were ineffective when used individually. Pure eugenol (MIC 0.25 mg/mL) was sufficient to fully eradicate E. coli strain 128 MR within 2 h whereas 1/2 MIC had only a bacteriostatic effect [79]. In the study of Wang et al [80], for most rare clinical colistin-resistant or native colistin-sensitive E. coli strains as well as the ATCC 25922 reference strain, eugenol exhibited a synergistic effect (FICi from 0.375 to 0.5) or additive effect (FICi = 0.625) with colistin and a bactericidal effect within 2 h in the time-kill assay was noted.…”

Avian pathogenic Escherichia coli (APEC) causes a variety of infections outside the intestine. The treatment of these infections is becoming increasingly difficult due to the emergence of multi-drug resistant (MDR) strains, which can also be a direct or indirect threat to humans as consumers of poultry products. Therefore, alternative antimicrobial agents are being sought, which could be essential oils, either administered individually or in interaction with antibiotics. Sixteen field isolates of E. coli (originating from 1-day-old broilers) and the ATCC 25922 reference strain were tested. Commercial cinnamon bark, clove bud, lavender flower essential oils (EOs) and enrofloxacin were selected to assess the sensitivity of the selected E. coli strains to antimicrobial agents. The checkerboard method was used to estimate the individual minimum inhibitory concentration (MIC) for each antimicrobial agent as well as to determine the interactions between the selected essential oil and enrofloxacin. In the case of enrofloxacin, ten isolates were resistant at MIC ≥ 2 μg/mL, three were classified as intermediate (0.5–1 μg/mL) and three as sensitive at ≤0.25 μg/mL. Regardless of the sensitivity to enrofloxacin, the MIC for cinnamon EO was 0.25% v/v and for clove EO was 0.125% v/v. All MDR strains had MIC values for lavender EO of 1% v/v, while drug-sensitive isolates had MIC of 0.5% v/v. Synergism between enrofloxacin and EO was noted more frequently in lavender EO (82.35%), followed by cinnamon EO (64.7%), than in clove EO (47.1%). The remaining cases exhibited additive effects. Owing to synergy, the isolates became susceptible to enrofloxacin at an MIC of ≤8 µg/mL. A time–kill study supports these observations. Cinnamon and clove EOs required for up to 1 h and lavender EO for up to 4 h to completely kill a multidrug-resistant strain as well as the ATCC 25922 reference strain of E. coli. Through synergistic or additive effects, blends with a lower than MIC concentration of enrofloxacin mixed with a lower EO content required 6 ± 2 h to achieve a similar effect.

“…The development of current and new technologies will result in the identification of plant-derived antimicrobials and their synergy with antibiotics [ 160 , 161 , 162 , 163 ], as well as the clarification of their complex mechanisms of interactions [ 164 ]. Therefore, the use of modern methods, antimicrobial testing with standardized protocols, and quality controls of plant materials are necessary.…”

Interactions between Medical Plant-Derived Bioactive Compounds: Focus on Antimicrobial Combination Effects

et al. 2022

View full text Add to dashboard Cite

It is accepted that the medicinal use of complex mixtures of plant-derived bioactive compounds is more effective than purified bioactive compounds due to beneficial combination interactions. However, synergy and antagonism are very difficult to study in a meticulous fashion since most established methods were designed to reduce the complexity of mixtures and identify single bioactive compounds. This study represents a critical review of the current scientific literature on the combined effects of plant-derived extracts/bioactive compounds. A particular emphasis is provided on the identification of antimicrobial synergistic or antagonistic combinations using recent metabolomics methods and elucidation of approaches identifying potential mechanisms that underlie their interactions. Proven examples of synergistic/antagonistic antimicrobial activity of bioactive compounds are also discussed. The focus is also put on the current challenges, difficulties, and problems that need to be overcome and future perspectives surrounding combination effects. The utilization of bioactive compounds from medicinal plant extracts as appropriate antimicrobials is important and needs to be facilitated by means of new metabolomics technologies to discover the most effective combinations among them. Understanding the nature of the interactions between medicinal plant-derived bioactive compounds will result in the development of new combination antimicrobial therapies.
