Thymus vulgaris L. is a well-know medicinal and aromatic plant native to the Mediterranean region. The essential oil is considered as the main active constituent, being responsible for its typical odour and taste as well as for several therapeutic effects. Our aim was to demonstrate the most important factors influencing the quality and quantity parameters of thyme oil by summarizing the available literature data and our own scientific results. Genetic background, climatic and growing conditions, techniques of primary processing, storage conditions as well as different extraction methods have proven effects on the essential oil properties and, as a consequence, on its biological activity, either.

The presence of different phytochemical components of essential oil such as tannins, alkaloids, terpenoids and phenolic compounds has antibacterial, antifungal, and anti-inflammatory effects. The aim of this study is to investigate importance of the major components of three herb essential oils (Thymus vulgaris L., Centauriumerythraea Rafn. And Foeniculumvulgare Mill) on challenging with fish diseases. The components of essential oils provided from a commercial firm were made GC/MS analyzes. The major component of T. vulgarewas carvacrol called as phenol, 2-methyl-5-(1-methylethyl) with 40%.The others were Linalool L (15.11%) and benzene, methyl(1-methylethyl)- (12.12%).The richest oil in C. erythraea was bicyclo[3.1.1]hept-2-ene, 2,6,6-trimethyl- (34.90%) called as alpha-pinene, followed by heptacosane (19.15%) and dotriacontane (17.72%), respectively.The evaluation of the essential oil of F. vulgarispresented benzene, 1-methoxy-4-(1-propenyl)- with 67.99%, followed by dl-Limonene (16.03%) and benzene, 1-methoxy-4-(2-propenyl)- (6.97%). The therapeutic effects of thyme are due to its high content of phenolic compounds, particularly carvacrol. The most important compounds of F. vulgare essential oil is anethole, fenchone, limonene that has antibacterial, antioxidant, antifungal and anticancer effects. The previous studies show that alpha pinene significantly inhibits many pathogenic Gram-negative bacteria. In aquaculture studies, in vitro and in vivo effects of the dominant compounds of essential oils in our study are consistent with the previous findings.

Mentha arvensis or mint is a renowned medicinal and aromatic plant. It is annual plant and cultivated in the tropical and sub-tropical regions under irrigation. Its cultivation has significant importance, such as for food flavoring, medicinal applications, essential oil applications, and also using in traditional purposes. Its essential oil contains many components phenolic, aldehydes, ketones, and carbohydrates. Menthol is a fundamental component of Mentha arvensis essential oil. Menthol has also several industrial applications, especially in food, cosmetics, pharmaceuticals, and by-products. There are many types or variations of menthol found in Mentha arvensis depending on the species or cultivars as well as cultivation conditions, such as weather, irrigation, soil type, pruning, and other agronomical practices. It has interesting and valuable botany, morphology, and ecology. Its growth rate is strongly affected by the change of variables, such as pH, temperature, and nutritional values of soil. The extraction of essential oil and the post-harvest analysis are done by using traditional methods for Mentha arvensis oil production in developing countries. Research on oil extraction methods, maximizing yield per hectare, and optimum preservation are needed for the further, especially in post-harvest of mint leaves and roots.

Initial Comparison

Feijoa is an aromatic fruit and the essential oil from feijoa peel could be a valuable by-product in the juicing industry. An initial comparison of the essential oil extraction methods, steam-distillation and hydro-distillation, was conducted. The volatile compounds in the essential oils from four feijoa cultivars were identified and semi-quantified by GC-MS and the aroma active compounds in each essential oil were characterized using SPME-GC-O-MS. Hydro-distillation, with a material to water ratio of 1:4 and an extraction time of 90 min, was the optimized extraction method for feijoa essential oil. The Wiki Tu cultivar produced the highest essential oil yield among the four selected cultivars. A total of 160 compounds were detected, among which 90 compounds were reported for the first time in feijoa essential oils. Terpenes and esters were dominant compounds in feijoa essential oil composition and were also major contributors to feijoa essential oil aroma. Key aroma active compounds in feijoa essential oils were α-terpineol, ethyl benzoate, (Z)-3-hexenyl hexanoate, linalool, (E)-geraniol, 2-undecanone, 3-octanone, α-cubebene, and germacrene D. This is the first report on the optimization of the extraction method and the establishment of the aroma profile of feijoa essential oils, with a comparison of four New Zealand grown cultivars.
