Abstract
The paper examines the chemical composition and antioxidant activity of free volatile aglycones
from laurel (Laurus nobilis L.) as compared to its essential oil. Comparison of the chemical
composition of volatile aglycones with the chemical composition of essential oil showed there
was no similarity between the free compounds found in the essential oil and the corresponding
volatile aglycones. Only eugenol was found to be identical. To evaluate the said antioxidant
activities, two different methods were applied: 2,2’-diphenyl-1-picrylhydrazyl radical scavenging
method (DPPH) and ferric reducing/antioxidant power assay (FRAP). The results obtained
in vitro with both methods showed that volatile aglycones from laurel possess lower reducing
power and free radical scavenging ability compared to essential oil as well as the well-known
synthetic antioxidant butilated hydroxytoluene (BHT).
