Screening of plant essential oils for antifungal activity against malassezia furfur

Abstract: Dandruff is a common scalp disorder affecting almost half of the population at the prepubertal age and of any gender and ethnicity. The fungus Malassezia furfur, a lipophilic yeast is widely accepted as the causative agent of dandruff, which due to its lipase activity releases proinflammatory free fatty acids causing dermal inflammation and tissue damage. Currently available treatment options of chemical origin have various limitations, either due to poor clinical efficiency or compliance issues. Also, these drugs are unable to prevent recurrence, which is the most common problem. Due to this, attention is shifting towards herbal remedies with aromatic plants and their essential oils being widely popular for their empirically antifungal properties. The present study was aimed to evaluate the potential inhibitory effects of essential oils of indigenous plants on M. furfur. The antifungal activity of four aromatic oils of kapur tulsi, cinnamon, eucalyptus, cajeput along with one fixed oil of karanj was screened alone or in combinations using tea tree oil and ketoconazole as standards. Out of five selected oils, three oils showed activity in the order cinnamon oil >kapur tulsi oil >cajeput while karanj oil and eucalyptus oil were inactive against the fungus. The minimum inhibitory concentration (MICs) of the active oils was evaluated using broth dilution method. The cinnamon oil, kapur tulsi oil and cajeput oil on evaluating in different combinations showed synergistic effect with a mixture of cinnamon oil and kapur tulsi oil exhibiting the best activity. The study reports effectiveness of kapur tulsi oil against M. furfur for the first time and further the synergistic combinations of oils is also being reported for the first time. The findings provide promising information on the potential use of essential oils for the treatment of dandruff.

Repellent Activities of Ocimum basilicum, Azadirachta indica and Eucalyptus citriodora Extracts on Rabbit Skin against Aedes aegypti

Abstract: Vector borne diseases are the major public health problems in developing countries particularly in tropics. Essential oils from plants can provide the safe and biodegradable alternatives to synthetic repellents, but plant-based repellent formulations available in the market are not effective. The purpose of the study was to investigate mosquito repellent activities of Sweet Basil (Ocimum basilicum), Neem (Azadirachta indica) and Lemon Eucalyptus (Eucalyptus citriodora) extracts. Different concentrations of the extracts were tested for mosquito repellency on rabbit skin as the host of Aedes aegypti. Laboratory reared starved females were used for the tests and data collection was done by observational parameters based on frequency of mosquito landing and blood engorgement. Synergised Crude oleoresin extract of Pyrethrum and Ballet mosquito repellent® were included as positive test controls and Vaseline pure petroleum jelly® as a negative test control. The results showed that synergised Pyrethrum oleoresin showed complete protection at 0.1% as compared to Lemon Eucalyptus oil and Sweet Basil oil at 2% and 3% respectively(p<0.05). Neem oil and Ballet did not provide complete protection. The mean percent repellency of 5% Neem oil was 84.21 and that of Ballet was 66.84 (p<0.05). Sweet basil and Lemon Eucalyptus oils can be alternative to Pyrethrum as natural mosquito repellents from plant origin.

Study the effect of essential oils on microbial biofilm formation by klebsiella pneumonia

Abstract: Microbial infections associated with biofilms formation through quorum sensing have imposed a serious problem in their treatment using conventional antibiotics. This has prompted researchers to identify alternatives such as plant products as antimicrobial agents. Research on plant derived natural antimicrobials agents, has almost exclusively focused on their effects against planktonic micro-organisms, however, the biofilm forms are more resistant to antimicrobial agents and therefore more difficult to control, remain largely unexplored. In view of this, the present study evaluated the antibiofilm activity of five different plant essential oils i.e., Garlic (Allium sativum), Eucalyptus (Eucalyptus grandis), Neem (Azadirachta indica), Tulsi (Ocimum sanctum), Clove (Syzygium aromaticum) on the growth of the Klebsiella pneumoniae NCIM 2719 strain on the abiotic surface like urinary catheter. Out of the five essential oil tested, the Eucalyptus oil showed the maximum inhibition in biofilm formation on both tube and on the surface of the catheter.

Effect of Garlic and Eucalyptus oils in comparison to Organophosphatinsecticides against some Piercing-Sucking Faba bean insect Pests and natural enemies populations

Abstract: The efficacy of garlic Allium sativum oil, and eucalyptus Eucalyptus globulus oil and their combinations with two organophosphorus pesticides, Dimethoate 30 % and Pestban 48% were evaluated for the control of some Piercing-Sucking insect pests associated with Faba bean Vicia faba in open field, during season 2011/2012. All of the four composites diluted to 3% before applying for four times in each spray. Samples were taken at the first, fifth, seventh and tenth days after application to determine the reduction in numbers. The results showed that, garlic oil was the best efficient in reducing the population of leafhoppers and planthoppers by a mean reduction percentage of 68.09%, followed by the two chemical insecticides Dimethoate 67.90 % and Pestban 64.02 %, and Eucalyptus oil was the least in this category as 43.27 %. However in controlling aphids, also garlic surpasses again by a mean overall reduction 90.96 %, followed by Pestban 89.44 %, while eucalyptus oil came in the third rank as 80.66 % before the dimethoate which achieved the least rank in controlling aphids as 76.14 %. Furthermore experiment was conducted also to evaluate the side effects of such composites on the population fluctuations of two insect predators rife in Fababean fields, true spiders and minute pirate bug (Orius sp.). Data showed that, in compared with control, the use of natural oils preserved partly the coexist of natural enemies than the use of chemical compounds in Faba bean fields.

Antilisterial Characteristics of Volatile Essential Oils

Abstract: OF THESIS ANTILISTERIAL CHARACTERISTICS OF VOLATILE ESSENTIAL OILS This study explored the in vitro and in situ antilisterial inhibitory activity of 16 essential oils during indirect exposure: Spanish Basil oil (Ocimum basilicum), Bay oil (Pimenta racemosa), Italian Bergamot oil (Citrus bergamia), Roman Chamomile oil (Anthemis nobilis), Sri Lanka Cinnamon oil (Cinnamomum zeylanicum), Citral, Clove Bud oil (Syzygium aromaticum), Cumin Seed oil (cuminum cyminum), Eucalyptus oil (Eucalyptus globulus), Eugenol, Geranium extract (Pelargonium graveolens), Marjoram oil (Origanum majorana), Neroli extract (Citrus aurantium), Peppermint oil (Mentha piperita L.), Rosemary oil (Rosmarinus officinalis L.),and Spanish Sage oil (Salvia officinalis L.). All essential oils were tested against Listeria monocytogenes (ATCC 4644). In vitro inhibitory activity was determined using the microatmosphere method at three temperatures (37°C, 24°C, 4°C) and six possible volumes (0, 10μl, 25μl, 50μl, 100μl, 150μl, or 200μl). In situ inhibitory activity was determined using inoculated bologna slices packaged in Modified Atmosphere Packaging (80% O2, 20% CO2). Essential oils (0, 0.13ml, 1.35ml, or 2.70ml) were injected into the sample packages adjacent, but not touching, the bologna slices and stored at 24°C for 24h. Basil oil displayed the least antilisterial activity across the three temperature applications in vitro. Peppermint, Cumin Seed, and Citral consistently exhibited the greatest antilisterial activity among the temperature applications in vitro. However, only Eugenol applied at 1.35ml achieved a mean one log10 CFU/ml reduction in LM in situ, which could not be replicated. Peppermint (P < 0.048) displayed significant differences between application volumes (0.13ml, 1.35ml) but did not attain a mean one log10 CFU/ml reduction in LM. This study suggests that while various essential oils can display antilisterial activity in vitro, transitioning into a MAP food system warrants further research in mode of actions and application volumes.
