ANALYSIS OF TERPENES IN MATRICARIA PERFORATA AND THYMUS PULEGIOIDES ON GEA-COM LTD. PASTURES USING GC-MS

Identification and monitoring of specific plant biomarkers in animal products and tissues can relate to feed and nutrition whereby lamb meat fed with pasturage contains more phenols, terpenes, indoles and sulfur compounds. Aromatic herbs, as part of hey/pasturage botanical composition, can affect sheep’s / lamb’s health, quality and aroma profile with their bioactive molecules. Numerous studies have confirmed a better aroma, color and quality of lamb meat and a more favorable composition of fatty acids. It all points to the possibility of producing functional lamb meat. During May, June and July 2019 on the pastures of GEA-COM Ltd. (Crkvina) there was a noticeable occurrence of Matricaria perforata and Thymus pulegioides, both of them rich in terpenes and terpenoids. Therefore, within the scope of the research, the content of aromatic hydrocarbons and derivatives in Matricaria perforata and Thymus pulegioides is determined using GC-MS analysis. The chemical composition of the Matricaria perforata identified by gas chromatographic and mass spectrometric data is listed: naphthalene, phenanthrene, benzophenone, trans-anethole, β-farnesene, aromadendrine, α-bisabolol, matricarin. Constituents found in Thymus pulegioides were α-Pinene, Camphene, β-Pinene, Myrcene, Eucalyptol, Carene, β-Ocimene, allo-Ocimene, Bornyl Acetate, α-Copaene, β-Bourbonen, Caryophyllene, β-Cubeben, α-Bergamotene, Germacrene D, Bicyclogermacrene, α-Farnesene, δ-Cadinene, Spathulenol, Caryophyllene Oxide. Since the breeding and feeding system of lambs on GEA-COM Ltd. farm may have significant influence on lamb meat aroma or on the composition of volatile compounds, it is the project's (HRZZ ; IP-2016-06-3685) interest to determine chemical composition (terpenes) of aromatic herbs from Crkvina pastures. Results could contribute to a better understanding of the environmental impact (plant flora) on the quality and aroma of Lika pramenka lamb meat.
