This review summarizes data on the in vitro antimicrobial effectiveness of volatile agents of plant origin and in vitro methods for evaluating their activity in the vapour phase. As a result of literature analysis, the antimicrobial efficacy of vapours from 122 different plant species and 19 pure compounds examined in 61 studies using different in vitro tests against a broad spectrum of microorganisms was identified and summarized. In addition, 11 different techniques found in the literature are described in detail. An original classification of methods based on the solid and liquid matrix volatilization principle is proposed because carrier medium/matrix selection is crucial for the volatilization of any agents tested. This review should be useful for medicinal, pharmaceutical, food, and agricultural experts working in areas related to the management of infectious diseases (especially respiratory and skin infections), food preservation (active packaging), and protection of agriculture products (controlled atmosphere). It may also stimulate the interest of pharmaceutical, cosmetic, food, and agriculture industries in the research and development of new antimicrobial agents of natural origin. Since several original apparatuses previously developed for antimicrobial susceptibility testing in the vapour phase are described in this review, labware manufacturers may also be interested in this topic. The review also provides specific guidelines and recommendations for researchers studying the antimicrobial activity of volatile agents. The article will therefore appeal to communities of industrial stakeholders, pharmacists, physicians, food experts, agriculturists, and researchers in related areas such as pharmacology, medicinal chemistry, microbiology, natural product chemistry, food preservation and plant protection.

“…Thymol and carvacrol applied as volatile phase vapor had strong antifungal activity against Geotrichum candidum , Lasiodiplodia spp., Pestalotiopsis spp., and Phomopsis spp. exhibiting MIC and MFC in the range of 40 to 80 mg/L (Suwanamornlert, Sangchote, Chinsirikul, Sane, & Chonhenchob, ). However, when the EOs from Thymus plant species are applied via direct contact (Boubaker et al., ), the MFC and MIC doses against G. citri‐aurantii ranged from 500 to 4000 µl/L, which were similar to the doses of thymol and carvacrol used in the present experiment.…”

Geotrichum citri‐aurantii causes sour rot in citrus fruits and is responsible for important economic losses during storage. However, the availability of chemical fungicides for the control of this pathogen is limited. Thus, the aim of this research was to evaluate the antifungal efficacy of thymol and carvacrol encapsulated in 2‐hydroxylpropyl‐beta‐cyclodextrin (HP‐β‐CD) (prepared by the microwave irradiation method [MW] and solubility method [S]) for inhibition of G. citri‐aurantii using in vitro bioassays broth (micro and macrodilutions methods) and inoculated food testing. Both encapsulated thymol and carvacrol were shown to be effective for inhibiting G. citri‐aurantii growth in in vitro assays. Thymol was more effective in inhibiting G. citri‐aurantii, while better encapsulation was provided by MW. HP‐β‐CD‐thymol encapsulated by MW (HP‐β‐CD‐thymol‐MW) showed the lowest 50% effective dose (ED50 = 1.16 mM), minimum inhibitory concentration (MIC = 5.06 mM), and minimum fungicide concentration (MFC = 52.6 mM). HP‐β‐CD‐thymol‐MW was found highly effective in reducing the growth rate and mycelial growth inhibition. Finally, HP‐β‐CD‐thymol‐MW and HP‐β‐CD‐carvacrol‐MW showed a higher persistent effect than thymol and carvacrol in their natural form in inhibiting this fungus. Therefore, HP‐β‐CD‐thymol‐MW could be a promising alternative to synthetic fungicides for controlling G. citri‐aurantii, the causal agent of citrus sour rot. Practical Application Encapsulated thymol and carvacrol in HP‐β‐Cyclodextrins are effective for controlling G. citri‐aurantii in in vitro experiments. Encapsulation of thymol and carvacrol by microwave irradiation method (MW) was more effective than the solubility (S) method. Thymol was more effective than carvacrol, and the best results on G. citri‐auriantii inhibition were achieved using the HP‐β‐CD‐thymol‐MW method (which gave the lowest ED50, MIC, and MFC).

Aim: To investigate the antifungal effect of the neem extract volatile propyl disulphide against the fungal plant pathogens. Methods and Results: Postharvest pathogens were isolated and identified as Lasiodiplodia theobromae and Neofusicoccum parvum causing the stem end rot of mango fruit. Antifungal activity of propyl disulphide at different concentrations was determined in comparison with ethanol and distilled water. Both diffusion assays were effective in controlling the mycelial growth of the tested fungi. The high coefficient of determination (R 2 , 0Á970-0Á997) of the growth curves indicated the good fit of the experimental data to the Gompertz growth model. Propyl disulphide significantly (P ≤ 0Á05) decreased the mycelial growth during the stationary phase (A) and increased the lag phase (k) than both control (ethanol and distilled water). Conclusion: This compound can potentially be applied to other tropical and subtropical fruits for the successful control of postharvest losses of fresh produce. Significance and Impact of the Study: This is the first report of propyl disulphide from neem extract against plant pathogens and could be beneficial for effective microbial decay prevention in food industries.
