Event Title

The extractives content soluble in ethanol-benzene of turkey oak (Quercus cerris L.) and Hungarian Oak (Quercus Frainetto Ten)

Session

Agriculture, Food Science and Technology

Description

There are many types of oak in Albania, but the species that have the greater spread and the largest area are: oak (Quercus cerris. L) and Hungarian oak (Quercus frainetto Ten.). The oak wood can be used in some fields and this because of its chemical and physical nature. The study was carried out in six sites along longitudinal gradient. Three stem discs from the bole R1, middle R2 and top R3 of the stem were taken from each tree. The extraction apparatus consisted of a soxhlet extractor and the extraction was conducted for five hours at the rate of approximately six siphonings per hour (25 siphonings in total). About Oak trees (Q. cerris L.), from all studied stations, the average values for the content of soluble extraction in alcohol / benzene (in base washers R1), Middle Ea / b (%) = 5.22 ± 1.41%. The Hungarian oak trees (Q. frainetto Ten.), from all studied stations, the average values for the content of soluble extraction in alcohol / benzene (in base washers R1), Middle Ea/ b (%) = 6.26 ± 1.7%.
