Fatty acid composition of achenes of cirsium taxa (Asteraceae, Carduoideae) from Turkey

PubMedID: 26959539The fatty acid compositions and total oil contents in achenes of 22 Cirsium taxa collected from different natural habitats in Turkey were investigated. The range of total fat in the taxa varied from 1.7% to 13.3%. The taxa contained palmitic (C16:0), stearic (C18:0), oleic (C18:1n-9), linoleic (C18:2n-6), and ?-linolenic (C18:3n-3) acid. Polyunsaturated fatty acids had the highest level, ranging from 52.1% to 75.2% (C18:2n-6) and 0.5%-17.3% (C18:3n-3). Total saturated (6.9%-17.4%), monounsaturated (11.7%-28.9%), and polyunsaturated (57.4%-79.9%) fatty acids varied substantially, whereas total unsaturated fatty acids ranged from 70.6% to 91.3%. Considerable variation was observed (P
