Two classical methods were applied for preparation of four plant extracts, i.e. heat reflux extraction and maceration, exactly for wormwood (Artemisia absinthium), yarrow (Achillea millefolium), oregano (Origanum vulgare) and primrose (Primula veris), plants from the spontaneous flora of Moldova area (Romania). The prepared extracts were preliminarily characterized by some known physical-chemical analytical methods used to evaluate various quality indicators of plant extracts (e.g. total polyphenols and flavonoids concentrations, density, viscosity) as well as comparative analysis of their UV-Vis and FTIR spectra. These vegetal extracts are non-toxic, and may have insecticide effect on the field of agricultural culture and storage pests.
