“…In the present work, twenty compounds were detected by GC-MS, and among them, sarcosine N -(trifluoroacetyl)-butyl ester, levulinic acid, propanedioic acid, palmitic acid, morphinan-6-one, 4,5 alpha-epoxy-3-hydroxy-17-methyl, 2,4-undecadiene-8,10-diyne- N -tyramide, and isovaleric acid compounds were detected for the first time in this work, according to the best of our knowledge. Some of the compounds identified in the studied extracts of A. pyrethrum (L), such as alkylamides ((2,4)- N -isobutyl-2,4-undecadiene-8,10-diynamide, N -isobutyl-dodeca-2,4,8,10-tetraenamide, N -isobutyl-2,4-octadiene-6-monoynamide, N -isobutyl-2,4-heptadiene-6-monoynamide, and N-isobutyl-2,6,8-datrienamide), were previously confirmed to have activities such as immunomodulatory, antithrombotic, antimicrobial, antiviral, antioxidant, anti-inflammatory, analgesic, anticancer, antidiabetic, and antiprotozoal activities [ 35 , 36 , 37 , 38 ]. Moreover, levulinic acid was found to have anti-inflammatory, anticonvulsant, and antioxidant activities [ 39 , 40 , 41 , 42 ].…”
