Özet:

In this study,  fatty acid composition, total phenolic contents, and antioxidant activities of the extracts obtained from the stem and seed parts of Euphorbia chamaesyce L. (Euphorbiaceae) were investigated. Linolenic and linoleic acids were determined as the main fatty acid components in the seed (32.42% and 15.04%, respectively) and stem (22.31% and 14.25%, respectively) hexane extracts by using GC/MS.  EC/SEM (seed methanolic extract, IC50 = 5.35 ± 0.01 µg/mL),  EC/SEA (seed acetone extract, IC50 = 8.61 ± 0.11 µg/mL), and EC/SEE (seed ethyl acetate extract; IC50 = 20.6 ± 1.12 µg/mL) exhibited higher radical scavenging effect than synthetic antioxidant BHT. Also, a positive correlation was found between the total phenolic content and DPPH radical scavenging activity. The results showed that the seeds of this plant had a high amount of polyunsaturated fatty acids and remarkable antioxidant activities.
