Abstract Two endemic Cirsium species, C. leucopsis DC. and C. sipyleum O. Schwarz, and C. eriophorum (L.) Scop. growing in Turkey were investigated to establish their secondary metabolites, fatty acid compositions, and antioxidant and anticholinesterase potentials. Spectroscopic methods were used to elucidate the structures of thirteen known compounds (p-hydroxy-benzoic acid, vanillic acid, cisepoxyconiferyl alcohol, syringin, balanophonin, 1′-O-methyl-balanophonin, apigenin, kaempferol-3- O-β-D-glucopyranoside, kaempferol-3-O-α-L-rhamnopyranoside, taraxasterol, taraxasterol acetate, β-sitosterol, β-sitosterol-3-O-β-D-glucopyranoside). cis-Epoxyconiferyl alcohol and 1′-O-methylbalanophonin were isolated for the first time from Cirsium species. Palmitic acid (47:1%) was found to be the main fatty acid of C. leucopsis, linoleic acid in both C. sipyleum (42:1%) and C. eriophorum (37:8%). Assays of b-carotene bleaching, scavenging of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals, 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium (ABTS) cation radicals, and superoxide anion radicals, as well as cupric reducing antioxidant capacity (CUPRAC) were used to determine the antioxidant activities of the extracts and isolated compounds. Vanillic acid, balanophonin, and kaempferol-3-O-α-L-rhamnopyranoside exhibited strong antioxidant activity. Taraxasterol was a potent inhibitor of acetyl- and butyrylcholinesterase activity, respectively.

Fatty Acid Compositions

Fatty acid compositions of seeds of five taxa of the Juniperus section of the genus Juniperus L. (Cupressaceae), i. e. J. drupacea Lab., J. communis L. var. communis, J. communis var. saxatilis Pall., J. oxycedrus L. subsp. oxycedrus, and J. oxycedrus subsp. macrocarpa (Sibth. & Sm.) Ball, were investigated. Methyl ester derivatized fatty acids of the lipophylic extracts of the five species were comparatively analyzed by capillary gas chromatography-mass spectrometry (GC-MS). Juniperus taxa showed uniform fatty acid patterns, among which linoleic (25.8–32.5%), pinolenic (11.9–24.1%) and oleic acids (12.4–17.2%) were determined to be the main fractions in the seed oils. Juniperonic acid was found to be remarkably high in J. communis var. saxatilis (11.4 %), J. oxycedrus subsp. oxycedrus (10.4 %), and J. communis var. communis (10.1 %). To the best of our knowledge, the present work discloses the first report on the fatty acid compositions of seeds of this Juniperus section grown in Turkey.

Fatty Acid Compositions

Seed oils of 18 species of Aceraceae (maple family) were examined and their fatty acid compositions were determined. Those of all but one species had substantial amounts of C20, C22, and C24cis-monoenoic acids. Acer rubrum, typical of the group, had 7% eicosenoic, 13% docosenoic, and 4% tetracosenoic acid in the total fatty acids of its oil. The chief isomers, identified in the oil of A. saccharum, were cis-11-eicosenoic, cis-13-docosenoic, and cis-15-tetracosenoic acids. The oils of Dipteronia sinensis and Acer negundo were much like the other Acer oils in composition, but that of A. saccharinum was composed almost entirely of the ordinary C16 and C18 fatty acids. The results are discussed in relation to the taxonomy of the family.

Fatty acid compositions of the seed oils of H. thermophilum Kit Tan, A. Celik & Y. Gemici, sp. nova, H. europaeum L., and H. hirsutissimum L. (Boraginaceae) were analyzed by GC/MS. The main fatty acid methyl esters were determined to be of palmitic (39.8–40.6%), linoleic (32.4–33.2%), oleic (10.6–12.1%) and stearic acids (7.9–8.5%). γ-Linolenic acid was found to be a minor component of the seed oils of the reported species. This is the first chemical report on the fatty acid composition of H. thermophilum, along with chemotaxonomic evaluation of the species.
