Opis:
An important trend in current cosmetic industry is increasing demand for new, biologically active compounds and preservatives of natural origin. These products constitute a major ingredients of natural (organic) cosmetics and usually may also be used in typical cosmetics as functional additives. This work summarizes the perspectives of the use of essential oils as active ingredients and preservatives in cosmetic products and as biopesticides. Brief characteristics of essentials oils, their preparation and biological activity is provided. Literature data suggests that essential oils exhibit broad therapeutic effects including antibacterial, antiseptic, antifungal and antioxidant activity, they can be also used as transdermal enhancers. On the other hand, in essential oil have been found compounds which can be use as a biopesticides. The use of essential oils in cosmetic products is possible, but requires a detailed knowledge regarding their compatibility, active concentration as well as toxicological and skin irritant characteristics. The literature review, presented in this paper, shows the great potential of essential oils as a biologically active preservatives and antioxidants, repellents and transepidermal enhancers.

Opis:
Introduction: In order to prevent increased bacterial resistance, it is important to use herbal medicines with less side effects. Objective: In this study, the chemical composition, antimicrobial, antioxidant activities and SEM images of Lavandula officinalis and Origanum onites oils obtained in two different ways were determined. Methods: The antimicrobial activity of the oils was determined against reference and multiple strains of foodborne and pathogenic bacteria. The each essential oil sample were analyzed by GC–MS. Antioxidant activities of the samples were examined through DPPH• and ABTS•+ radical scavenging and FRAP assays. Results: The results indicate that the oils of obtained from Origanum onites and Lavandula officinalis exhibited relatively strong antibacterial and antifungal activity. In addition, the antioxidant activities detected were remarkable. Morphological changes in bacterial cells treated with essential oil samples were demonstrated with SEM images. In addition, the chemical components of the oil samples obtained by both water steam and cold press were revealed by GC-MS analysis and compared. Conclusion: When all the obtained results are evaluated together; these plants could be suitable for using as antimicrobial and antioxidative agents in several industries such as food, cosmetic, etc.
