A Comparative Study on Fatty Acid Compositions, Total Phenolic Contents, and Antioxidant Potentials of Various Extracts from Different Parts of Euphorbia chamaesyce L.

Abstract

In this study, fatty acid compositions, total phenolic contents, and antioxidant effects of thestem and seed extracts from Euphorbia chamaesyce L. (Euphorbiaceae) were investigated.Linolenic and linoleic acids were found as the main fatty acid components in the seed and stemhexane extracts by using GC/MS. In the seed hexane extracts, linolenic and linoleic acids werefound as 32.42% and 15.04%, respectively. On the other hand, in the stem hexane extracts, theywere found as 22.31% and 14.25%, respectively. 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 (seedethyl acetate extract; IC50 = 20.6 ± 1.12 µg/mL) showed higher radical scavenging effect thansynthetic antioxidant BHT. The results showed that the seeds of E. chamaesyce had a highamount of polyunsaturated fatty acids and remarkable antioxidant activities.
