Zingiber officinale Rosc. is widely used as spice and medicinal plant in folk and traditional medicines. The aim of this study was to review the chemical composition and biological activities of Z. officinale (ginger) essential oil. Ginger oil is extracted from Z. officinale rhizomes, which its chemical composition influences from geographical region, extraction methods, freshness or dryness of rhizomes. The antibacterial, antifungal, analgesic, anti-inflammatory, anti-ulcer, immunomodulatory, relaxant, and warming effects of ginger oil have been confirmed in experimental and preclinical studies. The safety issues of ginger oils are well documented and are generally regarded as safe. Due to wide pharmacological effects of ginger oil, attention to ginger oil as an ingredient of natural formulations in management of gastrointestinal and respiratory diseases is valuable.

“…For instance, Miyasaki et al (42) showed that most of the de-tanninized parts of the Scutellaria baicalensis have a good effect against these bacteria (MIC 90 = 128 µg/mL). Karaman et al (43) also demonstrated that the methanolic extract of Juniperus oxycedrus L. has a good effect against A. Baumannii and (44) found that the extracts of Cinnamomum verum, Syzygium aromaticum, and Ocimumbasilicum Linn. volatile oils had an effective minimum bactericidal concentration against A. baumannii (MBC 90 = 0.5, 1, and 2 µg/mL, respectively).…”

Background Acinetobacter baumannii (A. baumannii) is a bacterium that is classified as opportunistic pathogens in hospitals, especially in immunocompromised patients and children. Regarding their role as pathogens, some studies in the last two decades have shown their involvement in many human infections, especially in intensive care units (1,2). A. baumannii colonizes the skin and upper respiratory tracts. It is isolated from urine, sputum, blood, and feces. In addition, it is usually found in hospitals on different surfaces. In other words, they are isolated from different locations within the hospitals (e.g., air, water faucets, bedsides, gloves, and catheters). Historically, this type of infection is associated with war-wounded due to the direct contamination of wounds in the surrounding environment. For example, it was the most isolated Gramnegative bacterium from the wounds of those wounded in the Vietnam War, as well as the case with those wounded in the US war in Iraq. Recent reports indicate an increased incidence of septicemia in military hospital patients (2). A. baumannii exhibits high resistance against most antibiotic groups because it owns genes that encode inhibitory enzymes (3). For example, carbapenemresistant A. baumannii strains show high resistance to most antibiotics, particularly beta-lactamase groups (4), because these strains own bla OXA-51-like and bla OXA-23-like genes which encode enzymes that inhibit the action of these antibiotics (5). Further, other studies demonstrated that most clinical isolates of A. baumannii were resistant to most cephalosporins (6), and this bacterium was also completely resistant to aztreonam, cefotaxime in addition to amoxicillin-clavulanic acid combination (7). Essential oils and plant extracts are used as new sources of antibacterial and antimicrobial agents in many fields (8), which include food preservation (9), pharmaceuticals, alternative medicine, and natural treatments (10-11). Furthermore, many plant extracts and oils are commonly used as medicinal plants in Syria for several purposes, especially for respiratory and gastrointestinal disorders. Considering the above-mentioned explanations, this study aimed to conduct a survey on the antibacterial activity of several antibiotics and essential oils, in vitro, against the isolates of A. baumannii obtained from children. Materials and Methods Identification of Bacteria Two hundred and one samples were collected from Children's Hospital of Damascus, Damascus, Syria from different sources (e.g., skin abscesses, bronchial secretions, urine, pharyngeal smears, and blood) during

“…500 grams of peel distilled for 4 hours and dried over anhydrous sodium sulfate gave 0.97% of kaffir lime oil with β‐pinene (30.48%), sabinene (22.75%), and citronellal (15.66%) being the major components 30 . Similarly, 3‐5 hours of hydrodistillation obtained 2.1% yield 31 . Hydrodistillation with 500 gram of peel for 4 hours using simple quick‐fit apparatus dried over anhydrous sodium sulfate resulted in production yield of 0.77% with 19 compounds majorly citronellol (10.67%), limonene (7.32%), linalool (5.83%), and o‐cymene (5.51%) 32 …”

Kaffir lime (Citrus hystrix DC) is a tropical plant with aromatic leaves. It produces fruits that are used in Asian cuisines as a flavoring agent. Essential oil from the leaves and peel of kaffir lime is a complex mixture of volatile and semi‐volatile compounds. It is rich in bioactive molecules that act synergistically to improve the well‐being of an individual. The method of extraction is important as it affects the quality and quantity of essential oil significantly. Kaffir lime oil is used as raw material in many fields, some of which include pharmaceutical, agronomic, food, sanitary, cosmetic, and perfume industries. It is also used extensively in aromatherapy and as an essential ingredient of various cosmetic and beauty products. Hydrodistillation, steam distillation, pressurized liquid extraction, and soxhlet extraction are some of the commonly used methods for extracting essential oil from kaffir lime as they are cost‐effective, environment friendly, and easy to implement on commercial scale. This review discusses about the condition's of extraction, merits, and demerits of various extraction methods used for kaffir lime oil and their application in healthcare products to induce positive effect in humans.
