Abstract :In this study, we investigated the effects of cold pressed oil on physicochemical properties of milk thistle insert ignore into journalissuearticles values(Silybum marianum);, anise seed insert ignore into journalissuearticles values(Pimpinella anisum);, fennel seed insert ignore into journalissuearticles values(Foeniculum vulgare);, terebinth insert ignore into journalissuearticles values(Pistacia terebinthus);, coriander insert ignore into journalissuearticles values(Coriandrum sativum); and nettle seed insert ignore into journalissuearticles values(Urtica dioica);. Selected oils from Central Anatolia Regions, were investigated in terms of the fatty acid methyl esters insert ignore into journalissuearticles values(FAME); compositions, peroxide value insert ignore into journalissuearticles values(PV);, free fatty acid insert ignore into journalissuearticles values(FFA);, refraction index insert ignore into journalissuearticles values(RI); at 40 ° C and oilseed yields. The data obtained from the analyses were evaluated chemometrically. The diagrams obtained by basic component analysis insert ignore into journalissuearticles values(PCA); and hierarchical clustering analysis insert ignore into journalissuearticles values(HCA);. According to PCA and HCA results, selected seed oils have different properties in terms of FAME, FFA, PV and RI. This suggests that each oil originates from the physicochemical properties of its unique pharmacological properties. As a result, in this study, data on the physicochemical properties of oils obtained from six medicinal plants was given. These results indicate that the seeds of the Central Anatolian region can be used as acceptable raw materials for herbal natural support products. These analyses can be used in order to assure the purity and quality parameters of seed oils. And FAME, PV, FFA and RI data can be good parameters to determine any adulteration to these oils by chemometric analysis.
