Laurus nobilis L. is one of the most valuable non-wood forest products on world export market and Turkey. Turkey is the biggest provider country for Laurus nobilis in the world. Therefore, laurel is an important commercial product for our country. In this study, the effects of cultivation area and altitude variation on essential oil content and quantity of laurel leaves were examined which grown in Trabzon, Bartın and Samsun. It was aimed to determine chemical composition of laurel's leaves grown in Karadeniz region. Laurus nobilis L. leaves were collected in three different height ranges. These were 0-100 m, 100-300 m, 300-600 m. Leaves were shade-dried and crushed. A device called ''Clevenger'' was used for getting volatile oil and their yields were calculated according to dry weight. The yields of essential oils ranged between 0.91% to 1.66 %. These essential oils were obtained from Bartin (B2) (100-300 m) and Artvin (A1) (0-100 m) respectively. The major components of these essential oils were 1,8-cineole (19.71%-35.63%), α-terpinyl acetate (12.86%-21.24%), sabinene (5.98%-9.40%), α-pinene (3.67%-8.45%) and β-pinene (2.91%-5.87%) were the most abundant volatile compounds in the leaves of bay.

“…We found that CIN was a major component of L. nobilis leaves (65% of essential oil) by GC-MS analysis that correlates with the findings of Sangun et al (2007) (50%), Yilmaz et al (2013) (Ozcan and Chalchat, 2005;Sangun et al, 2007).…”

“…1,8-Cineole (CIN) has been found main component of essential oil of Laurus nobilis L., an aromatic plant of Mediterranean region (Sangun et al, 2007;Yilmaz et al, 2013). Bay laurel is a perennial shrub with aromatic evergreen leaves and Turkey is an important exporter country Plant secondary compounds can have stimulating effect on C cycling and change its rate in soils.…”

“…These compounds delay oxidation by inhibiting the formation of free fatty acid radicals at the beginning with giving hydrogen from phenolic hydroxyl groups (Üstün and Turhan, 1999). Several researchers have also reported that essential oils and extracts obtained from laurel, thyme and rosemary are effective antioxidants (Bozin et al, 2006;Santoyo et al, 2006;Gachkar et al, 2007;Lie et al, 2009;Basmac›o¤lu Malayo¤lu et al, 2011;Yilmaz et al, 2013;Fadda et al, 2014).…”

“…(2004) reported that the inhibitory effect of LEO on the pathogens was in the following order: E. coli O157:H7 > S. aureus > L. monocytogenes. The inhibitory effect of LEO against various microorganisms using the agar well diffusion method was investigated by Yilmaz et al (2013) who reported that LEO showed antibacterial activity against E. coli O157:H7 (33 mm), S. aureus (ATCC 25923) (10 mm) and L. monocytogenes (ATCC 7644) (22 mm). Antimicrobial activity of essential oil obtained from laurel against L. monocytogenes (ATCC 7644), E. coli O157:H7 (ATCC 8739) and S. aureus (ATCC 25923) was also determined by Ekren et al (2013).…”

In this study, the antimicrobial and antioxidant properties of thyme (TEO), rosemary (REO) and laurel essential oils (LEO) and their mixtures (TEO/REO, TEO/LEO, REO/LEO, 1/1, v/v and TEO/REO/LEO, v/v/v, 1/1/1) were investigated. The antimicrobial activity was measured by the agar well diffusion method, while antioxidant capacity was measured using the FRAP and DPPH scavenging activity methods. All essential oils and their mixtures showed antimicrobial activity and antioxidant capacity. The highest antimicrobial activity against S. aureus, E. coli O157:H7 and L. monocytogenes was determined in TEO with zone diameters of 39.33, 28.00 and 30.67 mm, respectively. In general, essential oil mixtures negatively affected the antimicrobial activity compared to essential oils alone, and E. coli O157:H7 was less sensitive to the inhibitory activity of essential oils and their mixtures than S. aureus and L. monocytogenes. The FRAP values of all essential oils and mixtures ranged from 3.67 (REO) to 40.30 mg/mL (LEO), while the DPPH scavenging activity values ranged from 21.31 (REO) to 89.48% (TEO/LEO). These results suggest that essential oils obtained from thyme, rosemary, laurel and their mixtures have potential to be used as natural antimicrobial and antioxidant agents in the food industry.
