“…brevirostris leaves ethanol extract possessed antioxidant activity, where the prevailing antioxidants in the extract were gallic and ellagic acid (El-Ghorab et al, 2003). There are several more studies dealing with antioxidant activity of E. camaldulensis (Barra et al, 2010;Salem et al, 2015;Siramon and Ohtani, 2007;Olawore and Ololade, 2017), but it is interesting to mention here that E. camaldulensis flower EO inhibited melanogenesis through its antioxidant properties and by down-regulating both mitogen-activated protein kinases (MAPK) and protein kinase A (PKA) signaling pathways. This study indicated that the essential oil has the potential to be developed into a skin care product (Huang et al, 2015).…”

A B S T R A C TEucalyptus has become one of the world's most widely planted genera and E. camaldulensis (The River Red Gum) is a plantation species in many parts of the world. The plant traditional medical application indicates great antimicrobial properties, so E. camaldulensis essential oils and plant extracts have been widely examined. Essential oil of E. camaldulensis is active against many Gram positive (0.07-1.1%) and Gram negative bacteria (0.01-3.2%). The antibacterial effect is confirmed for bark and leaf extracts (conc. from 0.08 μg/mL to 200 mg/ mL), with significant variations depending on extraction procedure. Eucalyptus camaldulensis essential oil and extracts are among the most active against bacteria when compared with those from other species of genus Eucalyptus. The most fungal model organisms are sensitive to 0.125-1.0% of E. camaldulensis essential oil. The extracts are active against C. albicans (0.2-200 mg/mL leaf extracts and 0.5 mg/mL bark extracts), and against various dermatophytes. Of particular importance is considerable the extracts' antiviral activity against animal and human viruses (0.1-50 μg/mL). Although the antiprotozoal activity of E. camaldulensis essential oil and extracts is in the order of magnitude of concentration several hundred mg/mL, it is considerable when taking into account current therapy cost, toxicity, and protozoal growing resistance. Some studies show that essential oils' and extracts' antimicrobial activity can be further potentiated in combinations with antibiotics (beta-lactams, fluorochinolones, aminoglycosides, polymyxins), antivirals (acyclovir), and extracts of other plants (e.g. Annona senegalensis; Psidium guajava). The present data confirm the river red gum considerable antimicrobial properties, which should be further examined with particular attention to the mechanisms of antimicrobial activity.limited number of antiprotozoal and antiviral agents (El-Taweel, 2015;Irwin et al., 2016). This highlights the necessity for examination of new antimicrobial agents and treatment strategies of infections caused by the mentioned microorganisms.The plant kingdom represents the source of various medicines. Indeed, since ancient times medicinal plants play an important role of health care population and could represent a significant source of new antimicrobial drugs for combating pan-and multi-drug resistant microorganisms. These new antimicrobial agents could be hidden in medicinal plant extracts and essential oils. One of the significant medicinal plants is Eucalyptus camaldulensis. Thus, this review represents the summary of previous researches data, regarding chemical composition, antimicrobial activity, and other significant effects of Eucalyptus camaldulensis.

The word aromatherapy has become a household term, yet most of the people have no clear knowledge about its application. We would have a query that why plant produce essential oil, the reason is they protect the plant from fungal infection, insect pests and it attracts pollinators. Hence essential oil extracted from plants would be major source for antifungal and insecticidal agents. Studies were reported for the effect of essential oil components on food borne fungi and mycelia growth. The complex chemical constituents of essential oil could be due to the attraction of wide range of pollinators. Even though these volatile chemical constituents are naturally available in plants, extraction process plays the major role for its utilization. When plant material is subjected to steam distillation, the herb material under pressure which softens the cells and allows the essential oil to escape as vapour which was condensed and collected as essential oil. Various extraction processes have been evolved recently for the better yield of essential oil. Micro wave steam distillation and conventional steam distillation was noticed most common in the literature. This review is to discuss about the extraction methods, major constituents of various essential oils, and its application.
