Use of Essential Oils of the Genus <i>Citrus</i> as Biocidal Agents

Abstract

In this study, the essential oils extracted from the peels of Citrus aurantifolia, Citrus limon and Citrus sinensis were chemically characterized and quantified. These essential oils and their standards limonene, citral and limonene + citral were evaluated (at concentrations ranging from 500 to 3.91 mL·mL −1 ) regarding their anti-trypanosome, antifungal and antibacterial activities. The chemical identification and quantification (by GC/FID and GC/MS) displayed the limonene as the major component of the three essential oils. It did not verified antitrypanosome activity for all treatments. Regarding antimicrobial activity, the results were satisfactory against Gram-negative bacteria (Staphylococcus aureus, Listeria. monocytogenes and Salmonella cholerasuis) and funghi (Aspergillus niger, A. flavus and A. carbonarius), except for the bacterium Pseudomonas aeruginosa, which showed no inhibition for any treatment used.

Acaricidal properties of essential oils from agro‐industrial waste products from citric fruit against Tetranychus urticae

“…The high quantity of monoterpenes followed by sesquiterpenes in the present study, with limonene as the major constituent of the C. reticulate, C. reticulata × C. sinensis , C. aurantiifolia and C. limon oils, is in agreement with data published on samples collected in other locations of Brazil for oranges (Badawy, Taktak, & El‐Aswad, ) and limes/lemons (Amorim et al, ; Gomes et al, ). The abundance of monoterpenes with limonene as the major component of Citrus oils has also been reported for samples from other countries, such as C. aurantiifolia in Vietnam (Dang et al, ), Cameroon (Tchameni et al, ), India (Fagodia, Singh, Batish, & Kohli, ) and Australia (Mirzaei‐Najafgholi, Tarighi, Golmohammadi, & Taheri, ); C. limon in India (Jain & Sharma, ) and Iran (Ghoorchibeigi et al, ); and C. reticulate in Vietnam (Dang et al, ), China (Tao, Jia, & Zhou, ), Pakistan (Zia et al, ), Nigeria (Ayoola et al, ) and Egypt (Hamdan, Mohamed, & El‐Shazly, ).…”

“…On the other hand, the yields in the present study for the mandarin/tangerine oils ( C. reticulate and C. reticulata × C. sinensis ) were higher than those reported for samples collected in Faisalabad, Pakistan, by Sadaf, Shahid, and Iqbal (), who attributed the lower yield (0.18 ± 0.03%) to the ripeness of the fruit. Gomes et al () reported higher yields that those found in the present study for C. aurantiifolia and C. limon grown in Lavras, Brazil, whereas Ghoorchibeigi, Larijani, Azar, Zare, and Mehregan, () and Tchameni, Mbiakeu, Sameza, Jazet, and Tchoumbougnang () reported lower yields than those found in the present investigation for samples of C. aurantiifolia and C. limon collected in Iran and Cameroon, respectively.…”

Characterization of the Biological Potential of the Essential Oils from Five Species of Medicinal Plants

“…Food poisoning outbreaks are increasingly common, so there is a need to find compounds that are able to control bacterial strains resistant to antibiotics so as to reduce the contamination and deterioration of food-products [3]. This study sought to chemically characterize the essential oils from the following medicinal plants: M. piperita, C. citratus, R. officinalis, P. boldus and F. vulgare and to evaluate their antioxidant and antibacterial activities.…”

Effect of edible coatings with essential oils on the quality of red raspberries over shelf‐life

“…Citrus essential oils are used as flavors in soft drinks, ice cream, confectionery, bakery, or as fragrances in cosmetics, perfumery, soaps and cleaning materials. Nevertheless they also have biological properties such as insecticidal and antimicrobial activity . Owing to these properties, they can be used in edible coatings for the control of postharvest diseases, increasing the shelf‐life of fruits and vegetables.…”
