Essential‐Oil and Fatty‐Acid Composition, and Antioxidant Activity of Extracts of Ficaria kochii

Abstract

The essential-oil and fatty-acid composition of the aerial parts of Ficaria kochii (Ledeb.) Iranshahr & Rech.f. native to Iran, and the antioxidant activity of various extracts of this plant were examined. The study by GC-FID and GC/MS analysis of the essential oil resulted in the identification of 61 compounds, representing 86.01% of the total oil composition. Phytol (10.49%), farnesol (7.72%), methyl linoleate (5.57%), and α-farnesene (4.96%) were the main components. The fatty-acid composition of the aerial parts of F. kochii was also analyzed by GC/MS. The major components were palmitic acid (25.9%), linolenic acid (25.3%), and linoleic acid (17.5%). Polyunsaturated fatty acids (PUFAs) were found in higher amounts than saturated fatty acids. The possible antioxidant activity of various extracts (prepared by using solvents with different polarity) of the F. kochii aerial parts was evaluated by screening for their 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging activity, Fe(III) -reducing power, total antioxidant activity, and inhibitory activity in the linoleic acid-peroxidation system. H(2) O proved to be the most efficient solvent for the extraction of antioxidants, as the H(2) O extract contained the highest amount of phenolic compounds (2.78±0.23 GAE/g dry matter) and also exhibited the strongest antioxidant capacity in all the assays used. The results of the present investigation demonstrated that the aerial parts of F. kochii can be used as natural and safe nutrition supplement in place of synthetic ones.

The Essential Oil Constituents ofRanunculus marginatusd'Urv. var.trachycarpus(Fisch. & Mey.), From Turkey

“…trachycarpus. Therefore α-terpinyl acetate has not earlier been reported in the essential oil of R. arvensis, R. constantinapolitanus and R. kochii 29,30 . In previous studies involving the essential oils of Ranunculaceae plants, α-terpinyl acetate has not been found in the essential oils from Consolida regalis, Delphinium elatum, Nigella hispanica and N. nigellastrum 47 .…”

“…(Ranunculaceae) from Turkey by gas chromatography (GC) and GC-mass spectrometry (GC-MS). There are two reports on the essential oil compositions of R. arvensis and R. constantinapolitanus 30 29 .…”

“…Moreover, leaves of some Ranunculus species are consumed as food in the Black Sea region 15 . Flavonoids [16][17][18][19][20] , saponins 21,22 , alkaloids 23,24 , fatty acids and organic acids [25][26][27][28] , essential oils [29][30] were isolated by previous phytochemical studies of this genus. In previous studies, Ranunculus species have been shown to possess some activities such as antimicrobial [31][32][33] , cytotoxic 34 , anti-inflammatory [35][36][37][38] , antioxidant 39,40,32 and antiprotozoal 41 .…”

Bioconversion of lutein by Enterobacter hormaechei to form a new compound, 8-methyl-α-ionone

“…However, Tavakoli et al (2012) indicated that it was a minor component in an essential oil of Ficaria kochii but no isolation and validation characterization was given. Maldonado has reported that Robeldo et al (2005) Trichosporon asahii could cleave lutein to form bionone (Maldonado-Robeldo et al 2003), andZhao et al (2013) reported that Pantoea dispersa degraded lutein to form 3-hydroxy-b-ionone and b-ionone.…”

The Effect of Citrus Aurantium, Foeniculum Vulgare and Rosmarinus Officinalis Essential Oils on Peroxidase Activity

“…These compounds have therapeutic applications in traditional medicine for oral or external use (1)(2). So far, the presence of compounds with therapeutic properties such as antimicrobial, antioxidative, antifungal, antiviral and anticarcinogenic effects in essential oils, derived from plants and their associated chemical compositions are proven (3). In a study, the anti-ulcer and gastric mucosal tissue protective effect of essential oil of Citrus aurantium against ethanol-induced damage, has been reported as 99%.…”
