Abstract

The amount of carbon added to soil in the form of 1.8-Cineol was studied by determining the amount of 1.8-Cineol (C10H18O, 154.25 g/mol) in the leaves of Laurus nobilis L. Together with the

C (%) and N(%) contents in its soil and leaves sampled from three plants grown in Cukurova University Campus under the influence of Mediterranean climate. The amount of 1.8-Cineol of volatile oils extracted using Clevenger apparatus were determined by GS-MS techniques.

The amount of C (%) in soils and leaves of the three trees were 3.70, 3.96, 4.46 and 49.70, 43.80 and 58.49 respectively whereas the amount of N (%) in soils and leaves of these trees were 0,57; 0,35, 0,53 and 1,88, 1,62 and 0,85 respectively. The amounts 1.8-Cineol (%) of the leaves of these trees were 30.1, 37.75 and 24.65 and their carbon contents were 23.42, 29.37 and 19.18 respectively. Hence 47.12, 67.05 and 32.80% of the leaf carbon originate from 1.8-Cineol carbon. Difference among the carbon and nitrogen contents of soils of the tree trees were statistically different (P < 0.05) whereas statistical difference wasn’t observed among the leaves.

Active components of the plants are getting more important in the dynamics of organic matter and humus. In this context at mixed forests where various trees grow like Laurus nobilis L., it is clear that carbon content should also be taken into account together with the active substances of leaves.
