The Mediterranean Basin

Globe artichoke is considered one of the most important vegetable crops in the European and no-European countries of the Mediterranean basin. The Mediterranean region is well known for the 'Mediterranean diet', with attributed health benefits based on the consumption of fruits and vegetables, olive oil, etc. The artichoke has been recognized for the treatment of several ailments and their edible parts reveal therapeutic activity. In our case we have investigated the Micromani’s artichoke, which is a local variety of the Micromani area in the South region of Peloponnese. In the present work nutritional determination of vitamins such as “vitamin C “and folic acid, minerals, fibers and total phenolics was carried out.

The procedure for the determination of carbamate pesticides in soil was optimized. The following factors affecting the final results were investigated: extracting solvent, extraction procedure, extract purification procedure, and soil type. Triple extraction with acetone and purification of the extract on a two-stage purification column containing an activated carbon-silica gel 1+1 mixture were found optimal. The extracts after treatment were analyzed by RP-HPLC with UV detection. The method developed allows carbamate pesticides in soil to be determined at concentrations in excess of 30 μg kg-1.

Gradient Elution Mode

A novel analytical method involving high-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) was developed for simultaneous determination of 11 phenolic acids and 12 triterpenes in Sanguisorba officinalis L. Chromatographic separation was conducted with gradient elution mode by using a DiamonsilTM C18 column (250 mm × 4.6 mm, 5 μm) with the mobile phase of 0.1% acetic acid water (A) and methanol (B). The drift tube temperature of ELSD was set at 70 °C and the nitrogen cumulative flow rate was 1.6 L/min. The method was fully validated to be linear over a wide concentration range (R2 ≥ 0.9991). The precisions (RSD) were less than 3.0% and the recoveries were between 97.7% and 101.4% for all compounds. The results indicated that this method is accurate and effective for the determination of 23 functional components in Sanguisorba officinalis L. and could also be successfully applied to study the influence of processing method on those functional components in Sanguisorba officinalis L.
