Qualitative Properties and Antibacterial Activity of Essential Oil obtained from Citrus sinensis Peel on Three Selected Bacteria
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 19, Issue 4
Abstract
Medicinal plants are essential curative agents for different types of ailments. Citrus sinensis contains important micronutrients such as vitamin C and E, carotenoids and flavonoids, essential for maintenance of human health. The antibacterial activities of its essential oil were assessed against three selected bacteria. The result showed that the essential oil extracted with hot ethanol at 100 μL had a better inhibitory ability of 16 mm, 15 mm and 16 mm against Bacillus sp., Escherichia coli and Staphylococcus aureus respectively as compared to aqueous (cold and hot) 11 mm, 10 mm, 13 mm and cold ethanol (13 mm, 13 mm and 14 mm). The GC/MS analyses revealed that the orange peel oil extract is mainly composed of terpene hydrocarbons, oxygenated compounds and nonvolatile compound, many which constitute the antibacterial properties of the extract. It can be concluded that hot ethanol can be used for the extraction of oil from orange peel in the production of drugs for used in the treatment of Escherichia coli and Staphylococcus aureus. The spread of drug resistant microbial pathogens is one of the most serious threats to successful treatment of infectious diseases [1]. Some researchers reported that there is a relationship between chemical structures of the most abundant essential oil and antibacterial activity [2,3]. Plant derived components are a major area of interest to source for safer and more effective antibacterial agents [1]. Medicinal plants are essential curative agents for different types of ailments. To know the degree of effectiveness and enhance the use of herbal medicine, it is necessary to ensure intensive study of plants that are of medicinal importance. The Citrus sinensis contains important micronutrients namely vitamin C and E, carotenoids and flavonoids, essential for maintenance of human health. Multiple dietary sources of these compounds are present virtually in all plant material [4]. The nutritional importance of foods is due to the presence of these functional food ingredients and antioxidant nutraceuticals. The essential oil obtained from Citrus sinensis are found to have many medicinal properties and is widely used against various ailments such anaesthetic, anodyne, antiseptic, astringent, deodorant, diaphoretic, disinfectant, expectorant, febrifuge, fumigant, haemostat, inhalant, insect repellent [5], cold, stomach upset, cancer, diuretic, cormunative, immuno-enhancing, stomachic, tonic to the digestive system, immune system and skin. It is also used to treat and prevent vitamin deficiencies, colds, flu and scurvy and helping to fight viral and bacterial infections [6]. The medical potency of sweet orange (Citrus sinensis) is due to its high content in vitamin C which is believed to stimulate the production of white blood cells, primarily neutrophils, which attack foreign antigens such as bacteria and viruses [7]. It also boosts the body’s production of antibodies and interferon which help protect the body from viral invaders and cancer cells [8,9]. The aim of this study is to determine the qualitative properties and antibacterial activity of essential oil obtained from Citrus sinensis peel on three selected bacteria (Bacillus sp., Escherichia coli and Staphylococcus aureus).
