Essential oils (EOs) are complex mixtures of volatile and semivolatile compounds (aldehydes, ketones, alcohols and esters) obtained usually by hydro-distillation from the dry or fresh plant material (seeds, leaves, stems, bark or wood) [1]. Most of the EOs are used in aroma therapy, plant protection (as pesticide), food industry (as food preservatives), perfume industry etc. Because of high demand, EOs are often counterfeited and the quality of EOs is usually controlled by gas chromatography. The aim of this paper is to analyze Origanum oil and its counterfeits by Raman spectroscopy. As an adulterant sunflower oil was used. Adulterated essential oils contained 1, 2, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90% of sunflower oil. Raman spectra of pure Origano oil and its counterfeits were measured by Witec R300 system equipped with 532 nm laser. Visual inspection of raw spectra led to conclusion that band at 2851 1/cm is a marker for sunflower oil presence in Origanum oil. However, this band was obvious only when concentration of sunflower oil is higher than, or equal to 10% and could not be seen in lower concentration. In order to reveal presence of this this band in lower concentration, region between 2800 and 3000 1/cm was subjected to derivatization and then smoothing. Results displayed that Raman spectrea copy in combination with mathematical transformation of spectra can reveal small concentration of unwanted adulterant in Origanum oil.

AB  - Investigations were conducted in the green house of the Faculty of Agriculture with the aim of studying the influence of biostimulators on the quality of medicinal, aromatic and herb nursery plants. The nursery plants of basil (Ocimum basilicum L), lemon balm (Melissa officinalis L), cone flower (Echinacea angustifolia D.C), lavender (Lavandula angustifolia Mill), rosemary (Rosmarinus officinalis L) i marjoram (Majorana hortensis L) were grown in polystyrene containers (Speedling sys tem) 76 cm3 in size. The first part of the experiment was focused on the effect of the natural biostimulator Viva (3 ml/l) and Megafol (1.5 ml/l) on the quality of basil lemon balm and cone flower nursery plants. The second part of the study encompassed the influence of different Viva biostimulator rates (0 control, 1, 2, 3, 4 ml/l) on the quality of lavender, rosemary and marjoram nursery plants. Viva soil biostimulator and Megafol leaf biostimulators were added during the production of nursery plants at 10-day intervals. Based on the results obtained, a positive effect of natural biostimulator (Viva and Megafol) use was noted in the production of basil, garden balm and cone flower nursery plants. In addition, the use of different Viva biostimulator rates in the production of lavender, rosemary and marjoram nursery plants showed positive influence. The highest Viva biostimulator rate (4 ml/l) showed the most favourable effect on lavender and marjoram nursery plant quality. In case of rosemary nursery plants the rate of 3 ml/l was the most favourable.
AB  - U cilju proučavanja uticaja prirodnih biostimulatora na kvalitet rasada lekovitog, aromatičnog i začinskog bilja sprovedena su istraživanja u stakleniku Poljoprivrednog fakulteta u Beogradu. Rasad bosiljka (Ocimum basilicum L), matičnjaka (Melissa officinalis L), ehinaceje (Echinacea angustifolia), lavande (Lavandula angustifolia Mill), ruzmarina (Rosmarinus officinalis L) i majorana (Majorana hortensis L) je proizveden u polistirenskim kontejnerima (Speedling system) zapremine ćelije od 76 cm3. Ogled je podeljen na dva dela. U prvom delu ogleda ispitivan je uticaj prirodnih biostimulatora Viva (doza 3 ml/l) i Megafol (1,5 ml/l) na kvalitet rasada bosiljka, matičnjaka i ehinaceje. U drugom delu ogleda ispitivan je uticaj različitih doza (0 - kontrola, 1, 2, 3, 4 ml/l) Viva biostimulatora na kvalitet rasada lavande, ruzmarina i majorana. Rezultati istraživanja ukazuju na značajan, pozitivan, efekat upotrebe prirodnih biostimulatora Viva i Megafol u proizvodnji rasada bosiljka, matičnjaka i ehinaceje. Upotrebom različitih doza Viva biostimulatora u proizvodnji rasada lavande ruzmarina i majorana takođe su dobijeni značajni pozitivni efekti. Najveća primenjena doza biostimulatora Viva od 4 ml/l ostvarila je najveći efekat kod analiziranih parametara kvaliteta rasada lavande i majorana. Kod proizvodnje rasada ruzmarina najbolje rezultate dala je doza od 3 ml/l.
