Extraction and characterization of linden tree seed oil grown in Malatya with different solvents

In this study, the oil of linden seeds collected from Malatya region was taken by solvent extraction method and their characterization was made. Seeds for experiments at the end of August 2018, linden seeds in Malatya region were collected and their outer shells were separated from the seeds and oil was obtained with a Soxhlet device. Acetone, hexane and ethyl alcohol were used as solvents in the Soxhlet device. In order to determine the oil quality of the obtained oils, XRD, SEM, elemental analysis, ash determination, saponification number were subjected to a number of analyzes. As a result of the analyzes made, the oil yield with acetone was 28% by weight, with hexane 28.65% and 33% ethyl alcohol values were determined. In the fatty acid composition of linden tree seeds, the values by weight were found to be oleic acid: 27,442 for acetone, 30,852 for hexane, 10,9545 for palmitic acid: acetone, 11,929 for hexane, 51,188 for linoleic acid: acetone, 44,145 for hexane. The soap number values are 176.72 for hexane in mg KOH/g oil; 246.94 for acetone; It was found as 232.48 for ethyl alcohol. Ash determination values average 5,575%; bark ash was found to be 2.1% differently.
