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