“…The elimination of fatty substances is improved by increasing the weight of alumina from 250 to 350 mg per gram of olive oil. This result agree with that of Telling et al [26] who indicate that an excess of alumina is required in the clean up procedure. Our results confirm those found by Lentza Rizos et al [14].…”

Olive oil is the most important commodities produced in the Mediterranean region. Due to its significant economical importance, the usage of pesticides in its production is systematic, by using a wide range of plant protection products with a variety of modes of action. As a consequence, monitoring of their residue levels in these products is a necessity. In the present study a reversed-phase high performance liquid chromatography method, with a short sample preparation step, based on acetonitrile extraction is developed and validated in olive oil, with a large scope that includes Deltamethrin as pesticide. Good sensitivity and selectivity of the method were obtained with limits of quantification at 0.2 mg kg-1. Deltamethrin has recovery rate which is of about 80℅. We confirm also the efficiency of alumina, used as adsorbent in the clean up step, to remove triglycerides and to get a pure extract. The agronomic implementation of this protocol allows us to determine the influence of some parameters on the dose and the period of treatment affecting the detected quantities of Deltamethrin residues in the produced olive oil. Indeed, we prove that the treatment dose should be specific for each case considering the olive variety, the geography of the orchard, and the predicted harvest time to determine the convenient dose of treatment. In addition, the results show that the preventive treatment at the blooming phase, does not lead to the concentration of Deltamethrin residues in the oil as it happens at the lipogenesis phase.

“…Clean up process of levofloxacin was done by the technique described by Telling and Sissons (1977) with certain modifications carried out using solid-phase extraction C 18 cartridges. The dried eluate was reconstituted in 2ml of acetonitrile and loaded onto the conditioned C 18 cartridges and allowed to pass through vacuum (20mmHg).…”
