The presence of different phytochemical components of essential oil such as tannins, alkaloids, terpenoids and phenolic compounds has antibacterial, antifungal, and anti-inflammatory effects. The aim of this study is to investigate importance of the major components of three herb essential oils (Thymus vulgaris L., Centauriumerythraea Rafn. And Foeniculumvulgare Mill) on challenging with fish diseases. The components of essential oils provided from a commercial firm were made GC/MS analyzes. The major component of T. vulgarewas carvacrol called as phenol, 2-methyl-5-(1-methylethyl) with 40%.The others were Linalool L (15.11%) and benzene, methyl(1-methylethyl)- (12.12%).The richest oil in C. erythraea was bicyclo[3.1.1]hept-2-ene, 2,6,6-trimethyl- (34.90%) called as alpha-pinene, followed by heptacosane (19.15%) and dotriacontane (17.72%), respectively.The evaluation of the essential oil of F. vulgarispresented benzene, 1-methoxy-4-(1-propenyl)- with 67.99%, followed by dl-Limonene (16.03%) and benzene, 1-methoxy-4-(2-propenyl)- (6.97%). The therapeutic effects of thyme are due to its high content of phenolic compounds, particularly carvacrol. The most important compounds of F. vulgare essential oil is anethole, fenchone, limonene that has antibacterial, antioxidant, antifungal and anticancer effects. The previous studies show that alpha pinene significantly inhibits many pathogenic Gram-negative bacteria. In aquaculture studies, in vitro and in vivo effects of the dominant compounds of essential oils in our study are consistent with the previous findings.

Background: Coronavirus has become a life-threatening disease and it is caused by severe acute respiratory syndrome (SARS). This new strain of coronavirus is not completely understood and to date, there is no treatment for coronavirus. Traditional ayurvedic medicines, mainly essential oils and Chinese herbs, have always played a vital role in the prevention and treatment of several epidemics and pandemics. In the meantime, guidelines of the ministry of AYUSH (Ayurveda, yoga, unani, siddha and homoepathy) include a traditional medicinal treatment for flu and fever and also recommended to boost immunity to prevent the spread of coronavirus. It is not possible to find which essential oil will offer the best level of protection. However, it is likely to assume that some essential oils are likely to offer a measurable level of defense in the same way they do with many other known viruses. Methods: Literature relevant to various essential oils having antiviral activity has been collected and compiled. Various nanocarriers of essential oils have also been stated. The database was collected using various search engines such as J-Gate, Google Scholar, Sci-Hub, PubMed, ScienceDirect, etc. Results: Essential oils contain active constituents such as phenolic compounds, terpenoids, alkaloids, phenyl propanoids, etc., which are responsible for their biological properties such as antiviral, antibacterial, antimicrobial, antioxidant activities and many more. However, the use of essential oils has always been limited due to poor solubility, solvent toxicity, volatility and low solubility. Many nanotechnology based carriers especially, liposomes, dendrimers, nanoparticles, nanoemulsion and microemulsion, etc. have been evidenced to overcome limitations associated with essential oils. Conclusion: Several essential oils possess potent antiviral activity and are characterized by fewer side effects and are safe for human use. The nanocarrier systems of these oils have proved the potential to treat viral and bacterial infections. Lay Summary: Current COVID-19 era demands traditional treatment for immunity boost up as support therapy. Traditional ayurvedic medicines, mainly essential oils and Chinese herbs, have always played a vital role in the prevention and treatment of several epidemics and pandemics. Therefore, authors have summarized various essential oils having antiviral activity in current manuscript. Various nanocarriers of essential oils have been reported. Essential oils contain active constituents such as phenolic compounds, terpenoids, alkaloids, phenyl propanoids, etc., which are responsible for their biological properties such as antiviral, antibacterial, antimicrobial, antioxidant activity. However, the use of essential oils has always been limited due to poor solubility, solvent toxicity, volatility and low solubility.

Abstract We assessed the degree to which 16 post-infection treatments controlled Botrytis (Botrytis cinerea Pers. ex. Fr.) damage in cut roses (Rosa × hybrida). Additional experiments examined whether essential oils (EO) of cinnamon (Cinnamomum zeylanicum Blume) leaf (CLO), clove (Eugenia caryophyllata Thunb.) bud (CBO), and thyme (Thymus vulgaris L.) (TO) could reduce damage in Botrytis-infected cut roses. The 16 treatments applied to ‘Light Orlando' cut roses differed in reducing Botrytis damage and causing phytotoxicity damage. Only the synthetic fungicide fludioxonil [applied as 0.23 g · L−1 (0.00024 oz · fl oz−1) Medallion®] resulted in the desirable combination of greatly reduced stem termination frequency due to Botrytis damage and relatively minor flower phytotoxicity. When applied to cut rose ‘Freedom' or cultivars with light colored flowers (‘Cool Water', ‘Jessika', ‘Polar Star', ‘Tiffany'), all EO aqueous solutions caused pronounced phytotoxicity damage, but only TO reduced Botrytis damage significantly compared to untreated flowers. Roses exposed to EO vapor rather than an aqueous solution tended to exhibit less phytotoxicity. Vapors of CLO and CBO tended to reduce Botrytis damage less and caused greater flower phytotoxicity than TO vapor and aqueous fludioxonil. Thyme oil vapor exposures of 4.6 and 9.1 ppm warrant further investigation. Index words: Botrytis blight, Botrytis cinerea Pers. ex. Fr., cut flowers, floriculture, fungicide, gray mold, Rosa × hybrida. Chemicals used in this study: Bacillus subtilis (Cease®), bleach (Clorox®), chlorothalonil (Daconil®), copper sulphate (Phyton® 27), fenhexamide (Elevate®), fludioxonil (Medallion®), hydrogen peroxide (ZeroTol® 2.0), iprodione (Chipco® 26019 Flo), potassium bicarbonate (Milstop®), pyraclostrobin + boscalid (Pageant® Intrinsic®). Species used in this study: Rose (Rosa × hybrida) ‘Cool Water', ‘Freedom', ‘Jessika', ‘Polar Star', ‘Tiffany', Botrytis (Botrytis cinerea Pers. ex. Fr.).

The antiradical properties of essential oils from the inflorescences of Filipendula ulmaria (L). Maxim, herbages Hypericum perforatum L. and Pulmonaria mollis Wulfen ex HORNEM., growing on the territory of the Krasnoyarsk territory were studied. For this purpose, the reaction of essential oil components with a stable free 2,2-diphenyl-1-picrylhydrazyl radical was used. Essential oil of the plants under study received comprehensive hydroponically. The component composition of the oils was determined by chromatography-mass spectrometry. The main components of essential oil of F. ulmaria inflorescences are methyl salicylate (28.2%), salicylic aldehyde (2.8 %) and linalool (4.9%), essential oil of H. perforatum – γ - amorphene (30.7%), δ-cadinen (7.1%), (E, E)-β-farnesene (5.5%), caryophyllene (5.0%), ledol (5.0%), essential oil of P. mollis – di-n-butyl phthalate (18.7%), docosan (13.4%), tetracosan (11.6 %). The results of the DPPH test showed that the essential oils of the inflorescences of F. ulmaria and the aboveground part of H. perforatum and P. mollis exhibit antiradical activity (ARA). According to the size of the ARA of essential oils, the studied plants can be arranged in the following row: P. mollis > F. ulmaria > H. perforatum.

The aim of this study was to determine the effects of four essential oils intake by feed, namely Origanum vulgare, Thymus vulgaris, Cinnamomum zeylanicum Ness, and Syzygium aromaticum on antioxidant status in mice in vivo. Essential oils were in the aether oleum form. They were diluted with ethanol absolute mixed with ground pelett (0.1, 0.25, 0.57 and 1% concentration) and thereafter ethanol was evaporated. SOD, GPx activities and TAS were measured in erythrocytes and plasma spectrophotometrically with Ransod, Ransel and TAS kits from RANDOX, respectively. GPX activity showed a significant increase in 0.25% and 0.1% concentration of Origani aetheroleum. The GPx activities were decreased in 1% concentration of Thymi aetheroleum and 0.57% concentration of Cinnamomi aetheroleum and 0.57% concentration of Caryophylli aetheroleum. The total antioxidant status showed a significant decrease in 1 % concentration of Origani aetheroleum and significantly increased in 0.1% concentration. The same results were found in Thymi aetheroleum. Cinnamomi aetheroleum and Caryophylli aetheroleum had not effect on total antioxidant status. SOD activities were not significantly changed after intake of essential oils. In conclusion, our results showed, that concentration of essential oil is very important for antioxidant status and also for metabolism of mice, because a high dose of essential oil has adverse effect on metabolism of mice, representated by a lower growth of the body weight. On the other hand, essential oils at lower concentrations have positive effect on antioxidant status of mice.
