Chemical composition and fiber properties of rose wood (Rosa damascena Mill.) grown in Isparta Güneykent region

Abstract

The anatomical and chemical composition of naturally grown rose wood found in Isparta-Turkey was examined for the first time. Cell-wall main components, solubility values, structure and the amount of lipophilic and hydrophilic extractives of rose wood were determined. The amount of α-cellulose found in rose wood was 41.23 %, the holocellulose ratio was 81.05 %, the lignin amount was 20.02 %, the hot water solubility was 6.75 % and the 1% NaOH solubility was 19.26 %. The hexane solubility obtained by gravimetric methods was calculated as 0.19 mg/g, while the acetone:water (95:5, v:v) solubility results were obtained as 19.01 mg/g. Although 2-methyl-4-keto-pentan-2-ol (25.99%) was determined as the highest, ribose was found as the lowest in hydrophilics. Besides, benzoic acid (9.51%), α-d-mannopyranose (11.10%), and glucopyranose (9.43%) were the other hydrophilic compounds. N-ethylacetamide (39.03%) had the highest value in lipophilic exytactives. In addition, the structure and the dimensions of rose wood, analysed according to maceration method, was examined and calculations about fiber properties were realized.
