Resistance to conventional fungicides causes the poor disease control of agriculture plant essential oils have a great potential as novel fungicide sources for controlling pathogenic fungi. In this study antifungal activity of the essential oil of Cymbopogon distans and Cinnamomum tamala were evaluated in vitro against ten plants pathogenic fungal activity was evaluated with three replicates. The result showed C. distans and C. tamala essential oil with maximum zone of inhibition against Fusarium sp. (12.53 ± 0.97 mm) and P. aurantiogriseum (12.06 ± 0.52 mm) while minimum activity was seen against R. solani (6.83 ± 0.41, 6.16 ± 0.16 mm) zone of inhibition respectively. The highest efficacy was observed for C.distans essential oil where the MIC values 0.625 mg/ ml against A. flavus and Pythium sp. So, plant essential oils have the potential to replace the synthetic fungicides in the management of postharvest diseases of fruits and vegetables.

AbstractTwo novel cyclic hexadepsipeptides, fusarihexin A (1) and fusarihexin B (2), and two known compounds, cyclo-(L-Leu–L-Leu–D-Leu–L-Leu–L-Val) (3) and cyclo-(L-Leu–L-Leu–D-Leu–L-Leu–L-Ile) (4), were isolated from the marine mangrove endophytic fungus Fusarium sp. R5. Their chemical structures were elucidated on the basis of spectroscopic data and Marfeyʼs analysis. In an in vitro bioassay, fusarihexin A (1) remarkably inhibited three plant pathogenic fungi: Colletotrichum gloeosporioides (Penz.) Sacc., which causes anthracnose in many fruits and vegetables, Colletotrichum musae (Berk. and M. A. Curtis) Arx, which causes crown rot and anthracnose in bananas, and Fusarium oxysporum Schlecht. f. sp. lycopersici (Sacc.) W. C. Snyder et H. N. Hansen, which causes Fusarium wilt and fruit rot in tomatoes. Fusarihexin B (2) strongly inhibited C. gloeosporioides and C. musae. The compounds were more potent than carbendazim, which is widely used as an agricultural and horticultural fungicide worldwide.

In this study, antiphytopathogenic fungi activities of the leaf and cones essential oils and its constituents from Cunninghamia lanceolata were evaluated in vitro against 6 plant pathogenic fungi. The main compounds responsible for the antiphytopathogenic fungi activities were isolated and identified. The essential oil from the fresh leaves and cones of C. lanceolata was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS, respectively. The leaf oil consisted primarily of ferruginol (10%), τ-cadinol (8.2%), and α-cadinol (6.6%); the cones oil’s main constituents were abietadiene (42.5%), abietatriene (13.1%), and α-pinene (9.6%). Comparing the antiphytopathogenic fungi activities of the oils suggested that leaf oil was the most effective one. Further fractionation of the leaf oil produced ferruginol, τ-cadinol, and α-cadinol. The 3 compounds exhibited very strong antiphytopathogenic fungi activities. For the antiphytopathogenic fungi activities of the leaf oil, the active source compounds were determined to be ferruginol, τ-cadinol, and α-cadinol.

Abstract The yield, composition and fungicidal activity of essential oils obtained from fennel fruits cultivated in Poland (FEOPOL) and Egypt (FEO-EG) were compared. The influence of the duration of hydrodistillation using a Clevenger apparatus on the essential oil yield was studied. The composition of the fennel essential oils was determined by GC-MS method. Studies have shown that FEO-POL and FEO-EG are two distinct chemotypes, which differ in yield and composition. The fennel fruits cultivated in Poland contained 4.14% of essential oil with trans-anethole as a main component. The plant material from Egypt was characterised by low content of essential oil (1.32%) with a predominant share of estragole. The fungicidal activity was tested in vitro against ten species of pathogenic fungi. The best result for FEO-POL was achieved against Sclerotinia sclerotiorum, Rhizoctonia solani and Botrytis cinerea. Antifungal activity of FEO-EG against tested fungi was weak or none.

Plant essential oils have the potential to replace the synthetic fungicides in the management of postharvest diseases of fruit and vegetables.The aim of this study was to access the in vitro and in vivo activity of essential oil obtained from oregano (Origanum vulgare L. ssp. hirtum), thyme (Thymus vulgaris L.) and lemon (Citrus limon L.) plants, against some important postharvest pathogens (Botrytis cinerea, Penicillium italicum and P. digitatum). In vitro experiments indicated that P. italicum did not show any mycelium growth in presence of thyme essential oils at concentration of 0.13 μl/ml. Moreover, B. cinerea did not show any mycelium growth in presence of lemon and oregano essential oils at concentration of 17 μl/ml and 0.02 μl/ml, respectively. Moreover, the essential oils from three species were effective in reducing the spore germination. The in vivo experiments confirmed the strong efficacy shown in vitro by essential oils. These oregano and lemon oils were very effective in controlling disease severity of infected fruit by B. cinera in tomatoes, strawberries and cucumbers. In tomatoes, grey mould due to B. cinerea was completed inhibited by oregano essential oils at 0.30 μl/ml. Moreover, lemon essential oils induced a significant reduction of grey mould disease severity. In strawberries, grey mould was completed inhibited by lemon essential oils at 0.05 μl/ml. In addition, lemon essential oils at 0.05 μl/ml showed 39% reduction of infected cucumber fruits by B. cinerea. These results indicate that essential oils after suitable formulation could be used for the control of postharvest diseases caused by Botrytis and Penicillium pathogens.

A preparation of essential oils to control chicken lice (Menopon gallinae) and mites (Ornithonyssus bursa) was developed. Each essential oil was effective against lice and mite in vitro. Citronella oil at the lowest concentration of 0.208 µg/cm2 resulted in a mortality rate of 100% in chicken lice, whereas a higher concentration of cloves, lemongrass, ginger, Makwan oil (0.416 µg/cm2), and Litsea oil (0.832 µg/cm2) was also found to be effective. A 100% rate of mortality for mites was observed using citronella and ginger oil at a concentration of 0.416 µg/cm2. At the same concentration, cloves, lemongrass, Litsea, and Makwan oil exhibited mortality rates in mites of 77.96%, 93.33%, 87.30%, and 93.49%, respectively. The efficacy of citronella oil and ginger oil against lice and mites was further examined in vivo. Citronella and ginger oil affected the rate of decline in lice from day 1 to day 14, whereas the number of mites living in nests declined from day 1 to day 7. The reduction of these parasitic insects may be correlated with the chemical constituents present in each essential oil. The active ingredients likely acted insecticidal agents against both parasitic insects. Moreover, the preparation developed here did not cause any side effects, such as dermatitis and respiratory disorders, during animal trials. Hence, preparations comprised of the essential oils of citronella and ginger can be further developed and used as insecticidal agents to control and/or eliminate chicken lice and mites on commercial farms.

ABSTRACT Synthetic food additives generate a negative perception in consumers. This fact generates an important pressure on food manufacturers, searching for safer natural alternatives. Phytochemicals (such as polyphenols and thiols) and plant essential oils (terpenoids) possess antimicrobial activities that are able to prevent food spoilage due to fungi (e.g., Aspergillus, Penicillium) and intoxications (due to mycotoxins), both of which are important economic and health problems worldwide. This review summarizes industrially interesting antifungal bioactivities from the three main types of plant nutraceuticals: terpenoids (as thymol), polyphenols (as resveratrol) and thiols (as allicin) as well as some of the mechanisms of action. These phytochemicals are widely distributed in fruits and vegetables and are very useful in food preservation as they inhibit growth of important spoilage and pathogenic fungi, affecting especially mycelial growth and germination. Terpenoids and essential oils are the most abundant group of secondary metabolites found in plant extracts, especially in common aromatic plants, but polyphenols are a more remarkable group of bioactive compounds as they show a broad array of bioactivities.

Several essential oils of condiment and medicinal plants possess proven antimicrobial activity and are of important interest for the food industry. Therefore, the Minimum Inhibitory Concentrations (MIC) of those oils should be determined for various bacteria. MIC varies according to the oil used, the major compounds, and the physiology of the bacterium under study. In the present study, the essential oils of the plants Thymus vulgaris (time), Cymbopogon citratus (lemongrass) and Laurus nobilis (bay) were chemically quantified, and the MIC was determined on the bacteria Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Listeria monocytogenes ATCC 19117, Salmonella enterica Enteritidis S64, and Pseudomonas aeruginosa ATCC 27853. The essential oil of C. citratus demonstrated bacterial activity at all concentrations tested and against all of the bacteria tested. The majority of essential oil compounds were geranial and neral. The major constituent of T. vulgaris was 1.8-cineol and of L. nobilis was linalool, which presented lower antibacterial activity, followed by 1.8-cineol. The Gram-negative bacteria demonstrated higher resistance to the use of the essential oils tested in this study. E. coli was the least sensitive and was inhibited only by the oils of C. citratus and L. nobilis.
