Abstract

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.
