Sažetak
The sage (Salvia officinalis), laurel (Laurus nobilis), thyme (Thymus vulgaris), mastic tree (Pistacia lenticus L.), carob (Ceratonia siliqua) and myrtle (Myrtus communis) has many potential applications due to large number of bioactive molecules (BAM) with high antioxidant capacity (AOC). Currently it is an increasing interest in using these plants in the production of plant extracts (PE) and essential oils (EO) for food, pharmaceutical and cosmetic industries. However, extraction yield and antioxidant activity of PE depend on selection of appropriate extraction technique and solvent used for extraction. Therefore, the aim of this study was to determine the AOC of PE obtained by successive extraction with three different extraction solvents (hexane, 80 % acetone and 96 % ethanol) and extraction techniques (ultrasound assisted (UAE), accelerated solvent (ASE) and shaking water bath extraction). The plant extracts were analysed using the ORAC method. Results showed that ASE is the most appropriate method for extraction BAC’s from thyme, mastic tree and carob while UAE was better method for sage and laurel, whose extracts contribute the highest AOA.
