Abstract

In this study, the chemical structure of the wood and bark of willow (Salix alba L.), grown naturally in the Lakes Region, was investigated. The main components of the cell wall, the solubility values, the amount of lipophilic and hydrophilic substances obtained by hexane and acetone:water (95:5, v:v) extraction of willow wood and bark, and also fatty acid composition and suberin analysis were studied in the bark. Holocellulose amount was determined in wood and bark, respectively, as 81.70% and 70.18%, α-cellulose 48.42% and 40.32%, klason lignin 24.01% and 33.81%, hot water solubility 4.09% and 21.51%, 1% NaOH solubility 13.88% and 43.48%, hexane solubility 8.24 mg/g and 10.64 mg/g, acetone:water solubility 31.26 mg/g and 30.72 mg/g. Linoleic acid (25.89%) in wood and N-ethylacetamide (32.94 %) in bark were determined as the major lipophilic substances after hexane extraction. In additon, after hexane extraction, the amount of fatty acids was investigated in the bark samples according to the Supelco 37 fatty acid mixture, 9,12-octadecadienoic acid (55.71 %) was found to be predominant fatty acid. 2-methyl-4-keto-pentan-2-ol (17.00%) in the wood and sucrose (32.24%) in the bark were seen as the most common components as hydrophilic substances after acetone:water extraction.

Özet

Bu çalışmada Göller Bölgesi’nde doğal olarak yetişen Söğüt (Salix alba L.) ağacının odun ve kabuğunun kimyasal yapısı araştırılmıştır. Söğüt ağacının odun ve kabuk örnekleri üzerinde hücre çeperi ana bileşenleri, çözünürlük değerleri, heksan ve aseton:su (95:5, v:v) ekstraksiyonu ile elde edilen lipofilik ve hidrofilik madde miktarı ve bileşenleri araştırılmış olup ayrıca kabukta yağ asidi tayini ve suberin analizi yapılmıştır. Holoselüloz oranı odun ve kabukta %81.70 ve % 70.18, α-selüloz %48.42 ve %40.32, lignin miktarı %24.01 ve %33.81, sıcak su çözünürlüğü %4.09 ve %21.51, %1’lik NaOH çözünürlüğü %13.88 ve %43.48, heksan çözünürlüğü 8.24 mg/g ve 10.64 mg/g, aseton:su çözünürlüğü 31.26 mg/g ve 30.72 mg/g olarak tespit edilmiştir. Heksan ektraksiyonu sonucu elde edilen lipofilik madde miktarları ve bileşenleri arasında, odunda linoleic asit %25.89, kabukta ise N-ethylacetamide %32.94 olarak en yüksek oranda tespit edilen bileşenlerdir. Heksan ekstraksiyonu sonrası kabuk örneklerinde Supelco 37’li yağ asidi karışımına göre yağ asitleri miktarları araştırılmış ve 55.71 mg/g ile 9,12-octadecadienoic acid en baskın bulunan yağ asidi olarak tespit edilmiştir. Aseton:su ekstraksiyonu sonucu elde edilen hidrofilik madde miktarları ve bileşenleri incelendiğinde ise odunda 2-methyl-4-keto-pentan-2-ol (%17.00) ve kabukta sucrose (%32.24) en fazla bulunan bileşenlerdir.
