Abstract:

 

In this study, the Eminium rauwolffii (Blume) Schott var. rauwolffii taxon’s tubers and seeds from Turkey were evaluated for their fatty acids. The seed and tuber oil content (%) and fatty acid compositions were determined. The oil contents of the seeds and tubers were 2.89/100 g and 0.86/100 g, respectively. Among the fatty acids for seeds, linoleic acid (18:2n6) was the most abundant (25.01%), followed by oleic acid (18:1n9, 14.45%), palmitoleic acid (16:1, 11.6%), and palmitic acid (16:0, 10.28%). In addition, among the fatty acids for tubers, linoleic acid (18:2n6c) was the most abundant (26.22%), followed by palmitic acid (23.42%, 16:0), oleic acid (16.78%, 18:1n9), and myristic acid (7.05%, 14:0). The total percentages of the saturated and unsaturated fatty acids identified in our examined oils were 14.17 and 55.89% for seed and 44.71 and 45.87% for tubers, respectively. In conclusion, the seed and tuber oil of Eminium rauwolffii (Blume) Schott var. rauwolffii is richer in unsaturated fatty acids compared with saturated fatty acids.

 

Bu çalışmada, Türkiye’den toplanan Eminium rauwolffii (Blume) Schott var. rauwolffii taksonunun tuber ve tohumları yağ asitleri açısından değerlendirilmiştir. Tohum ve tuberlerin yağ miktarları (%) ile yağ asitleri bileşimi belirlenmiştir. Tohum ve tuberlerin yağ miktarları sırasıyla 2.89/100 g ve 0.86/100 g olarak bulunmuştur. Tohum yağ asitleri arasında en fazla miktarda bulunan yağ asidi linoleik asit (%25.01, 18:2n6), ardından sırasıyla oleik asit (%14.45, 18:1n9), palmitoleik asit (16:1, %11.6), ve palmitik asittir (16:0, %10.28). Ayrıca, tuber yağ asitleri arasında en fazla miktarda bulunan yağ asidinin linoleik asit (%26.22, 18:2n6), ardından sırasıyla palmitik asit (%23.42, 16:0), oleik asit (%16.78, 18:1n9), miristik asit (%7.05, 14:0) olduğu gözlenmiştir. İncelenen yağlarda tanımlanan doymuş ve doymamış yağ asitlerinin toplam yüzdeleri tohum için sırasıyla %14.17 ve %55.89 iken tuberler için ise sırasıyla %44.71 and %45.87’dir. Sonuç olarak, Eminium rauwolffii (Blume) Schott var. rauwolffii taksonunun tohum ve tuberlerindeki yağlarda doymamış yağ asitleri miktarının doymuş yağ asitleri miktarından daha fazla olduğu bulunmuştur.
