tailieunhanh - A comparative study on the fatty acid composition of the oils from five Bupleurum species collected from Turkey

The oil content and fatty acid compositions of 5 Bupleurum species (B. intermedium, B. lancifolium, B. croceum, B. rotundifolium, and B. cappadocicum) were determined. Their oil contents ranged from to . Gas chromatography (GC) was used for the fatty acid composition. | Turk J Biol 36 (2012) 527-532 © TÜBİTAK doi: A comparative study on the fatty acid composition of the oils from five Bupleurum species collected from Turkey Hatice TANER SARAÇOĞLU, Gökhan ZENGİN, Mehtap AKIN, Apdurahman AKTÜMSEK Department of Biology, Science Faculty, Selçuk University, Konya - TURKEY Received: ● Accepted: Abstract: The oil content and fatty acid compositions of 5 Bupleurum species (B. intermedium, B. lancifolium, B. croceum, B. rotundifolium, and B. cappadocicum) were determined. Their oil contents ranged from to . Gas chromatography (GC) was used for the fatty acid composition. Twenty-one fatty acids were identified and quantified by GC. Oleic acid (C18:1) accounted for more than 50% of the total fatty acids in 3 of the Bupleurum species (B. intermedium, B. lancifolium, and B. rotundifolium). The total unsaturated fatty acid contents varied from in B. cappadocicum to in B. rotundifolium. The total saturated fatty acids represent to of the total lipid content. The main saturated fatty acids were palmitic (C16:0), stearic (C18:0), and myristic (C14:0). Moreover, cluster analysis was performed to determine the relationship between the species in terms of the fatty acid profiles. Key words: Bupleurum, Apiaceae, fatty acid composition, unsaturated fatty acids, Turkey Introduction Fatty acids are the main component of lipids such as phospholipids, triglycerides, and monoglycerides. They can be saturated (no double bond), monounsaturated (1 double bond), or polyunsaturated (2 or more double bonds). Fatty acids have many important biological properties such as energetic, metabolic, and structural activities. Moreover, they can be associated with some chronic and degenerative diseases. For example, the consumption of mono/poly unsaturated fatty acids is beneficial in reducing cholesterol and thus the risk of myocardial diseases (1). Therefore, unsaturated fatty acids .
