Çilek çekirdeği yağının (SSO) yağ asidi kompozisyonunu ve sterol içeriği belirlenmiştir. Yağ asidi kompozisyonu ve sterol içeriği, gaz kromatografisi (GC) ile analiz edilmiş, tokoferol ve gliserid içeriği, bir ters faz kolonu ile donatılmış yüksek performanslı sıvı kromatografisi (HPLC) cihazı ile belirlenmiştir. Çilek çekirdeği yağının fizikokimyasal özellikleri de incelenmiştir. Sonuçlar, çilek çekirdeği yağının esas olarak oleik asit (%15.58), linoleik asit (%42.54) ve linolenik asit (%33.48) gibi doymamış yağ asitlerinden (%92.36) oluştuğunu göstermiştir. Çilek çekirdeği yağındaki toplam sterol bileşenlerinin 932.00 mg/kg olduğu ve baskın sterolün β-sitosterol (%81.04) olduğu belirlenmiştir. Toplam β-sterol içeriği %83.84 olarak tespit edilmiştir. SSO'da baskın triaçilgliserol (TAG) moleküllerinin sırasıyla OLnL (%13.99), LLL (%8.05) ve PLnL (%4.41) olduğu belirlenmiştir. Ayrıca, çilek çekirdeği yağının fenolik bileşikler, tokoferoller ve steroller gibi diğer biyoaktif bileşikler açısından da zengin olduğu tespit edilmiştir.

Fatty Acids Composition and Bioactive Substances of Cold Pressed Oils from Strawberry Seed

Öz

Fatty acid and sterol compositions of strawberry seed oil (SSO) were determined. The fatty acid and sterol compositions were analyzed by GC. Tocols, tocotrienols and glycerides composition were designated on a high performance HPLC equipped with a reversed-phase HPLC columns. The physicochemical characteristics of strawberry seed oil were also studied. Our results showed that the strawberry seed oil was composed mainly of unsaturated fatty acids (92.36%), such as oleic acid (15.58%), linoleic acid (42.54%) and linolenic acid (33.48%). The total sterol constituents in strawberry seed oil were determined as 932.00 mg/kg and the major sterol was β-sitosterol (81.04%). The total β-sterol composition was 83.84%. Dominant triacylglycerol (TAG) molecules in SSO were determined to be OLnL (13.99%), LLL (8.05%) and PLnL (4.41%), respectively. Furthermore, the strawberry seed oil was rich in other bioactive compounds, such as phenolic compounds, tocopherols and sterols.
