Studies performed with the bioproduct obtained by hydrodistilation of Satureja hortensis, a Romanian indigenous plant, showed the presence of Tymol (47.18%), o-Cymene (22.38%) and Eucalyptol (7.59%). The bioproduct contains macro and microelements like Ca (42.6 ppm) and Fe (0.001 ppm). Studies regarding antioxidant properties, indicated a total antioxidant activity ranged between 99.4-99.9% for this bioproduct. Biological tests reveal the antifungal activities against Rhizoctonia solany (DL50= 219 mu L.L-1), Botrytis allii (DL50= 175 mu L.L-1), Sclerotinia sclerotiorum (DL50= 222 mu L.L-1) and Fusarium graminearum (DL50= 165 mu L.L-1). In conclusion, the bioproduct obtained from SH represents a bioproduct with antioxidant and biological activities against some phytopatogens.
