    Antioxidant activity is one of the most important properties of plant extracts. Antioxidants from natural sources have been intensively studied in the last few decades. The antioxidant contents of medicinal plants may contribute to the protection of diseases. Bioactive components of plants have a potential role in chemoprevention and inhibition of different phases of the malignant transformation process. Therefore, plant extracts and essential oils are in the focus of research, and in recent decades have been tested on a large number of malignant cell lines. The aim of this study was to examine antioxidant and cytotoxic potential of selected plant species from the Boraginaceae family. Determination of antioxidant activity was performed by ammonium-thiocyanate method. Testing citotoxic activity was performed by MTT test on cancer cell lines: HEP 2c (human larynx carcinoma), RD (human cell line-rhabdomyosarcoma) and L2OB (mouse tumor fibroblast line). The best antioxidant activity showed ethanol, acetone and chloroform extracts of Anchusa officinalis, Echium vulgare and Echium italicum. The tested extracts showed an inhibitory effect on cancer cells, but chloroform and acetone extracts of all three plant had the most effective effect on L2OB cells. Isolation of individual active components from this plants and their testing for cancer cells would be of great importance for this field of research.

    The biological characteristics of lettuce and its specific growth and development are the basis for establishing the optimal method of cultivation. In order to achieve appropriate high yields, producers various organic, mineral and microbial fertilizers. The aim of the study was to determine the effect of fertilization on the growth and quality of different varieties of lettuce. A two-factor experiment (fertilization and variety) was set up on a random block system in a greenhouse without heating, on the territory of East Sarajevo. A non-fertilized control variant was included in the trial. During the research, the effect of fertilizers (Slavol and Fitofert humisuper) on two varieties of lettuce (Santoro RZ and Kiribati RZ) was examined. The highest mass of lettuce was recorded on the variant with application of Slavol (309,19 g).The highest percentage of dry matter was achieved by fertilization with Slavol in the Kiribati RZ variety – 6,46%, while the lowest percentage was achieved on the control variant in the Santoro RZ variety - 5.10%.
