Tomatoes (Solanum lycopersicum L.) have highmoisture content (93–95%), making them more vulnerable to various types of spoilage fungi. Numerous medicinal plants' essential oils are known to have antifungal properties that combat these spoilage fungi. Therefore, this study aimed to investigate the potential antifungal activity of essential oils from some indigenous plants in Bangladesh to prevent the fungal attack on tomatoes. Using potato dextrose agar medium, 4 species of spoilage fungi from tomatoes were identified. ITS (Internal transcribed spacer) region-specific sequencing was used to identify the fungal species as Aspergillus welwitschiae, Aspergillus tamari, Penicillium citrinum and Rhizopus arrhizus. Assessment on antifungal activity was conducted for four essential oils extracted from plants: turmeric leaf (Curcuma longa), patchouli (Pogestemon cablin), palmarosa (Cymbopogon martini) and lemongrass (Cymbopogon citratus). The GC-MS method was used to analyze these essential oils to ascertain their chemical content. A pathogenicity test determined the severity and % of rot on tomatoes. A. welwitschiae caused the most severe spoilage (80%) after 21 days, while R. arrhizus damaged 26% of the tomatoes within 5 days. The minimal fungicidal concentration (MFC) and minimal inhibitory concentration (MIC) of the essential oils were determined after analysis. Lemongrass oil fully suppressed the growth of all the isolates at a concentration of 12 ????l/ml. Finally, the essential oils of palmarosa and lemongrass may be used as a preventative measure against tomato fungal rot.

“…Several studies have reported essential oils as the best antifungal and antibacterial agents due to their broad-spectrum activity (Ferdosi et al, 2022;Ferdosi et al, 2021). Often these oils are obtained from plants including Zingiber officinale, Curcuma longa, Eucalyptus globulus, Syzygium aromaticum, Nigella sativa, Elettaria cardamomum, Cinnamomum verum and Cuminum cyminum.…”

Plant essential oils have been used in traditional medicines since ancient times to combat disease and in agro-food science to preserve food stuff. Antifungal activity of plant essential oils was evaluated using different substrates of varied moisture levels against ochratoxin A (OTA) producing Aspergillus ochraceus. A. ochraceus (n = 3) isolates were processed for antifungal activity of various essential oils including Zingiber officinale, Curcuma longa, Eucalyptus globulus, Syzygium aromaticum, Nigella sativa, Elettaria cardamomum, Cinnamomum verum and Cuminum cyminum extracted by hydro-distillation. To check the antimicrobial activity of essential oils, the highest zone of inhibition recorded was of C. verum (33.67±0.57mm) followed by S. aromaticum (30.33±0.57mm) and the least minimum inhibitory concentration (MIC) was of S. aromaticum (0.52±0.22 µg/mL) followed by C. verum (0.65±0.22 µg/mL). Antifungal activity was evaluated in term of log reduction and at the exposure time of 60 and 90 min, 6±0.00 log reduction was observed by S. aromaticum, C. verum and E. cardamomum with non-significant differences. At 15 th , 30 th , 45 th and 60 th day of experiment, toxin production by A. ochraceus at moisture contents (10, 20, 30, 40, 50, 60 and 70%) in un-inoculated groups and inoculated treated groups with C. verum Essential Oils were found non-significantly different to each other but significantly different from the OTA production in inoculated groups of wheat, maize and rice (intact and broken). At 10% moisture level, OTA production was low and reached to maximum level at 40% moisture level and again decline with increasing moisture level. Cinnamon has showed antifungal activity against A. ochraceus at all moisture levels. The confirmation of inhibition potential of C. verum was evaluated using thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC) techniques. This study illustrates that cinnamon oil is effective to inhibit the growth of OTA producing A. ochraceus in stored grains to overcome the economic losses.
