“…The inhibition radius around the oil disk (colony-free perimeter) was measured using a digital vernier caliper (Mitutoyo, Kawasaki, Japan). Mycelia growth (cm) was recorded and the percentage inhibition (PI) was determined after comparison with the control ( Pandey et al, 1982 ; Trabelsi et al, 2016 ). The minimal inhibitory concentration (MIC) was defined as the lowest concentration of CEO at which the growth of microorganism was inhibited ( Rasooli and Abyaneh, 2004 ).…”

In this study, one of the dominant pathogens, which caused postharvest diseases such as anthracnose, was isolated from decayed ‘Hongyang’ kiwifruit. It was identified as Colletotrichum acutatum by its morphological characteristics and standard internal transcribed spacer ribosomal DNA sequence. Further, the efficacy and possible mechanism of cinnamon essential oil on inhibition of C. acutatum were investigated. Results showed that C. acutatum was dose-dependently inhibited by cinnamon essential oil. Meanwhile, the mycelial growth and spore germination of C. acutatum were completely inhibited at the concentrations of 0.200 μL/mL and 0.175 μL/mL (v/v), respectively. Indeed, both minimal inhibitory and minimum fungicidal concentrations of cinnamon essential oil were measured as 0.200 μL/mL. Additionally, the possible antifungal mechanism of cinnamon essential oil on C. acutatum was demonstrated. Results showed that the cinnamon essential oil could destroy the cell membrane integrity of C. acutatum, and the structure of cell membrane was changed. Indeed, the cell cytoplasm including soluble protein, sugar, and nucleic acid was released, which significantly changed the extracellular conductivity. Results suggested that the cinnamon essential oil exerted great potential to be used as a natural and efficient preservative for kiwifruit postharvest storage, which were helpful for the better understanding of the efficacy and mechanism of cinnamon essential oil on inhibition of pathogens isolated from decayed ‘Hongyang’ kiwifruit.

The Antifungal Potential of Carvacrol against Penicillium Digitatum through 1H-NMR Based Metabolomics Approach

et al. 2019

Carvacrol (5-Isopropyl-2-methylphenol), a volatile oil constituent, mainly exists in Labiaceae family plants. Carvacrol has long been studied for its natural antifungal potential and food preservative potential. However, its exact mode of action, especially against Penicillium digitatum (P. digitatum), remains unexplored. Herein, a 1 H-NMR-based metabolomic technique was used to investigate the antifungal mechanism of carvacrol against P. digitatum. The metabolomic profiling data showed that alanine, aspartate, glutamate, and glutathione metabolism were imbalanced in the fungal hyphae. A strong positive correlation was seen between aspartate, glutamate, alanine, and glutamine, with a negative correlation among glutathione and lactate. These metabolic changes revealed that carvacrol-induced oxidative stress had disturbed the energy production and amino acid metabolism of P. digitatum. The current study will improve the understanding of the metabolic changes posed by plant-based fungicides in order to control citrus fruit green mold caused by P. digitatum. Moreover, the study will provide a certain experimental and theoretical basis for the development of novel citrus fruit preservatives.aroused by excessive use of certain routine and synthetic antifungal agents. Over the past few decades, the intentions have been to ensure the hygiene and safety levels of fruit products along with promoting maximum biodegradability. In order to achieve this ambition, researchers are still trying to screen natural products with strong antifungal potential from plants. Moreover, it has also been tried to explore new preservation technologies that can replace synthetic fungicides. Compared with synthetic fungicides, natural antifungal substances have attained much attention in recent years [6][7][8][9].Various essential oils refined from Melaleuca alternifolia have strong inhibitory effects on multiple fungal strains, particularly P. italicum Wehmer and P. digitatum Sacc., and hence can be used as natural preservatives in agricultural and food processing [10]. Previously we have reported that cinnamaldehyde contained in cinnamon has a good antifungal effect against P. italicum and clarifies the method for dynamic detection of the antifungal effect of cinnamaldehyde [11]. In addition, GC-MS and GC-FID techniques successfully separated the essential oils components viz. limonene (87.02%), linalyl acetate (53.76%) and linalool (39.74%) from peels, leaves and flowers of Citrus aurantium var amara, neroli oil appeared as the best fungistatic agent, which reduced the P. digitatum sporulation to 25 % at a 50 mg/mL concentration of oil [12].Carvacrol (5-Isopropyl-2-methylphenol) is the major volatile oil constituent from Labiaceae family plants, such as oregano, mint, and thyme [13].

Effects of UV and X-ray treatments on oxidative stability of soybean oil were evaluated during accelerated storage. Furthermore, antioxidant activity of neroli oil incorporated into soybean oil was compared with those of BHT and β-carotene. UV and X-ray treated samples had significantly higher peroxide (105.00 and 191.99 meq O 2 /kg, respectively), anisidine (62.30 and 153.80 mg/kg, respectively), and Totox values (272.3 and 453.43, respectively) than non-irradiated samples (75.74 meq O 2 /kg, 26.50 mg/kg, and 177.98, respectively). The X-ray radiation accelerated the oxidation of soybean oil more significantly than UV radiation did. This could be due to the fact that X-ray radiation has a higher energy content. In addition, neroli oil proved its antioxidant activity in soybean oil. Nonetheless, neroli oil had a lower antioxidant activity than BHTa chemical agentwhile β-carotene was neither antioxidant nor pro-oxidant. In conclusion, neroli oil can improve the oxidative stability of irradiated and non-irradiated soybean oil.
