Types Benefits How to use Side effects and risks Takeaway Overview. Types of antifungal essential oils. against some common fungal pathogens of plants and animals namely, Fusarium moniliforme NCIM , Fusarium oxysporum MTCC , Aspergillus sp. All fungal species were found to be inhibited by the oil when tested through agar well diffusion method.

Minimum inhibitory concentration MIC was determined for all the species. Column chromatography was performed to separate the eugenol rich fraction from clove oil. Out of seven fractions maximum activity was obtained in column fraction II. TLC and HPLC data confirmed presence of considerable Eugenol in fraction II and clove oil.

Microscopic study on effect of clove oil and column fraction II on spores of Mucor sp. and M. gypseum showed distortion and shrinkage while it was absent in other column fractions. So it can be concluded that the antifungal action of clove oil is due to its high eugenol content. Evaluation of antifungal activity in essential oil of the Syzygium aromaticum L.

by extraction, purification and analysis of its main component eugenol. com ; Aarti Singh Rana, Ram Charan Rajak.

In the past few decades, a worldwide increase in the incidence of fungal infections has been observed as well as a rise in the resistance of some species of fungus to different fungicides in medicine and agriculture.

The last two decades have witnessed a dramatic rise in the incidence of life threatening systemic fungal infections. The majority of clinically used antifungals have various drawbacks in terms of toxicity, efficacy and cost, and their frequent use has led to the emergence of resistant strains.

Additionally, in recent years public pressure to reduce the use of synthetic fungicides in agriculture has increased. Concerns have been raised about both the environmental impact and the potential health risk related to the use of these compounds 1. The use of plant derived products as diseases control agents have been studied, since they tend to have low mammalian toxicity, less environmental effects and wide public acceptance 5.

Essential oils have a long history of use as natural microbial agents and have recently been used in a number of pharmaceutical, food, and cosmetic products since these oils effectively inhibit the growth of a wide range of microorganisms, with fewer side effects than synthetic antimicrobial agents in humans.

Despite the widespread use of essential oils, details about the exact mechanism of their antimicrobial action are yet to be explored. Thus, many researchers have recently attempted to identify the antimicrobial properties of essential oils. Clove oil has been widely investigated due to its popularity, availability, and high essential oil content Clove oil Syzygium aromaticum is widely used as a perfume and food flavoring 22 , as a medicine for the treatment of asthma and various allergic disorders in Korea 12 , and as a general antiseptic in medical dental practices 6.

Ahmad et al. Clove oil was found to possess strong antifungal activity against opportunistic fungal pathogens such as Candida albicans , Cryptococcus neoformans and Aspergillus fumigatus. The essential ingredient responsible for its antifungal activity is eugenol from the clove Eugenol is the main volatile compound of extracted oil from clove bud S.

aromaticum L. that is used in traditional medicine, as a bactericide, fungicide 3, 4 , anesthetic, and others However, its antimicrobial activity was found to be higher against fungi than against bacteria 9.

The purpose of this study was to examine the antifungal activity of clove essential oil extracted from floral buds against dermatophytes, such as Trichophyton rubrum, Microsporum gypseum, and plant pathogenic fungi such as Fusarium moniliforme , Fusarium oxysporum , Aspergillus sp.

and Mucor sp. The major constituent of the clove oil eugenol was also purified and analyzed in this study through chromatographic techniques. Also the effect of clove oil on fungal spores was studied.

The dried flower buds of clove plant used in this study were purchased from local market of Bhopal, India. The buds were identified and authenticated by Dr. Clove buds g were powdered in a grinder and it was subjected to steam distillation, using the Clavenger apparatus Pyrex , as described by Harbone Distillation was done for 4 hours and the oil was drained off and dried over anhydrous sodium sulphate 4.

Mucor sp. and Aspergillus sp. were isolated from soil samples; Microsporum gypseum and Trichophyton rubrum were obtained from Fungal Germplasm Culture Collection Center, Department of Biological Sciences, R. University, Jabalpur, India. Fusarium monoliforme NCIM was procured from NCIM, NCL, Pune, India and F.

oxysporum MTCC was procured from MTCC, IMTECH, Chandigarh, India. All the fungal cultures were maintained on Potato Dextrose Agar PDA , Himedia, India, slant medium supplemented with 0.

For the preparation of inoculum, all the test fungi were raised on Sabouraud Dextrose Agar SDA , Himedia, by incubating the petriplates at 28±1 ˚C for 7 days in a BOD incubator. Fungal spore suspensions ml were prepared in sterile distilled water containing 0.

Preliminary screening of antifungal activity of clove essential oil EO was done through agar well diffusion assay Spore suspension of each isolate was prepared by taking a single fungal disc aseptically with a 5 mm cork borer from sporulating culture and mixed in 20 ml sterile distilled water to which 50 µl of Tween was added.

The total number of spores was determined by counting under microscope using haemocytometer Neubauer counting chamber. Petriplates containing SDA Himedia were inoculated aseptically with µl spore suspension through spread plate technique and kept in the.

laminar flow for 30 min. Wells of 5 mm diameter were punched in the center of the petriplates by using sterile cork borer. Into each well, 10 µl of the clove EO was dropped followed by 40 µl of dimethyl sulphoxide DMSO so as to make the 50 µl total volume in the well.

Plates were kept in refrigerator at 4 ˚C for 3 h, to allow EO and DMSO to diffuse into the agar medium. Plates were finally incubated at 28±1 ˚C for 5 days. Ketoconazol at the concentration of 1 mg in 1 ml of DMSO was used as positive control. DMSO without clove oil was set as negative control.

The diameter of the zone of inhibition around each well was measured in mm. Minimum inhibitory concentration MIC was determined for all the fungal strains through agar dilution method. Tween 0. Plates were inoculated in the center with mycelial disc 4 mm and incubated for 5 days followed by measurement of mean radial colony diameters.

Three replicates were made for each treatment and medium with Tween alone was set as control. The plate with lowest concentration of clove EO, showing no visible growth was regarded as the MIC Clove EO was subjected to column chromatography for fractionation based on increasing solvent polarity.

Silica gel mesh slurry was made in petroleum ether ˚C and poured into a glass column 60 x 3 cm, ASGI, India with sintered disc, to make an effective column of 45 x 3 cm size. Analytical grade solvents of Qualigens, India were used. Ten milliliter of clove oil was loaded onto column bed and eluted first with ml petroleum ether followed by ml each of ether:chloroform , chloroform:ethyl acetate , chloroform:ethyl acetate , chloroform:ethyl acetate and lastly with methanol.

Column fractions were collected in pre weighed conical flasks ml and were later concentrated by using rotary vacuum evaporator, buchi type Scientech, India at 50 ˚C and finally weighed. Antifungal potential of all the six column fractions was determined through agar well diffusion assay. Fractions were equally diluted with µl ethanol in order to dissolve the crystallized fractions.

Quantity used for bioassay was 5 µl along with 45 µl of DMSO, to make final volume of 50 µl. Silica gel TLC was performed for analysis of column fractions along with eugenol standard. Silica plates of 1 mm thickness were prepared with silica gel H Qualigens, India by using TLC apparatus Perfit India Ltd.

Plates were activated in an oven Tempo, India for 2 hours at 65 ˚C. Six column fractions 5 µl each were spotted with the help of Hamilton syringe Germany along with eugenol standard. Petroleum ether, toluene and ethyl acetate in a combination of was used as developing solvent.

When the solvent phase reached the top, the plate was air dried and exposed to iodine vapours in a glass chamber for 30 min. The plate was then taken out and photographed HPLC analysis of clove oil and laboratory reagent LR grade eugenol Oxford Chemicals, India was done in isocratic mode by using Shimadu's prominent HPLC system using a reverse phase C18 column [Phenomenex Luna, 5μ C18 2 A ×4.

One hundred milligrams of EO was dissolved in 5 ml of mobile phase solvent and 20 µl was injected. The eugenol content was quantified based on the peak. Microscopic study of effect of clove EO and fraction II on fungal mycelium and spores.

Fifty microliters of clove EO and fraction II were put on the center of the glass slides. Fresh fungal mycelium piece bearing spores was taken out of petriplate with inoculating needle and immersed in the drop of clove oil on slides.

After 1 h of incubation at ambient temperature, the slides were examined under light microscope and photographed. The results of the preliminary screening shown in Fig. Considerable variation in inhibition zone sizes ranging from mm was observed among fungal isolates depending on their sensitivity towards clove EO.

The order of sensitivity in the descending array was Mucor sp. The positive control ketoconazole was very effective even at low concentration as it showed higher inhibition zones against all the fungal strains.

No inhibition zones were observed with in negative control DMSO. Lee et al. Their results suggest that eugenol and nerolidol could apply supplementary antifungal agents.

Nunez et al. albicans, P. citrinum, A. niger and T. albicans , C. neoformans and A. gypseum and T. and F. Mycelial inhibition was concentration dependent as the colonies diameters were decreased with increasing quantity of EO.

Pinto et al. They determined MIC to evaluate the antifungal activity of the clove oil and its main component, eugenol, against Candida , Aspergillus , and dermatophyte clinical and ATCC American Type Culture Collection strains.

The essential oil and eugenol showed inhibitory activity against all the tested strains. Table 2 shows that among the column eluents, highest quantity of 5. All other eluted components were in meager quantity.

Non polar fractions were oily and light colored while polar fractions were solids and dark colored. This gave an indication that column fraction II may contain substantial amount of eugenol. It is also possible that some minor compounds present in fraction II may have promoted the inhibitory potential to some extent.

In rest of the fractions no inhibition was observed. TLC results of column fractions Lanes along with eugenol standard Lane 7 are shown in Fig. Upon exposure of TLC plate to iodine vapors the result clearly shows presence of high quantity of eugenol in column fraction II.

Small quantity of eugenol was also present in fraction III as a result of which little inhibition zones were also observed in this fraction.

The non polar oily compounds in fraction I moved faster with developing solvent close to the solvent front. The highly polar compounds in fraction V travelled only few centimeters, and that of fraction VI didn't moved at all on TLC plate. The R f value calculated for column fraction II at lane 2 and for eugenol standard was 0.

The result of antifungal assay of column fractions and that of TLC proves that the antifungal activity of the clove oil is due to its high eugenol content. Park et al. They performed TLC and column chromatography assay to identify the active antifungal components and their fractionation.

They concluded that eugenol was the most effective antifungal constituent of clove oil against the dermatophytes T.
