Antioxidant Properties and Monoterpene Composition of 13 Different Pine Resin Samples from Turkey

Pine resin has been used as a traditional health-promoting medicinal food in Turkey and some countries for centuries. In the present study, antioxidant potential monoterpene profile of 13 pine samples purchased from herbalists different provinces were investigated. According to analysis results, there differences between samples, especially terms color properties. The experimental results demonstrated that had strong in-vitro effects. Total phenolic, FRAP, DPPH (EC50) values ranged 23.19 379.44 mgGAE g-1, 68.85 758.80 µmol Fe2+ 54.36 1006.97 µg respectively. phenolic content correlated well with FRAP values. contrast, it was found negative correlation EC50 (r=-0.719**) total substance (r=-0.688**). Also, compounds determined by applying solid-phase microextraction (SPME) gas chromatography-mass spectroscopy. Eight identified including α-pinene, camphene, β-pinene, 3-carene, β-myrcene, cymene, D-limonene, p-cymene. Generally, main monoterpenes α-pinene β-pinene.
