Sažetak
Sage (Salvia officinalis L.) is an aromatic and medicinal plant rich in biologically active components, including terpenes and polyphenols. Polyphenols comprise a large group of compounds, including phenolic acids, flavonoids and phenolic diterpenes. Phenolic diterpenes greatly contribute to antioxidant activity of sage extract and some compounds identified within this class are carnosic acid, carnosol and rosmarinic acid. In addition to antioxidant activity, carnosic acid contributes to positive health effects of sage extract as well. The aim of our study was to optimize supercritical fluid extraction (SFE) variables such as extraction pressure, temperature and CO2 flow rate in order to obtain the maximum amount of carnosic acid in sage leaves extracts. Carnosic acid content was determined by high-performance liquid chromatography (HPLC) and expressed as µg of CA/g of extract. The content of carnosic acid was in the range from 0.29- 120.05 µg mg-1 of extract, depending on applied extraction conditions as stated above. The temperature exhibited the most significant influence on content of carnosic acid (p = 0.0063). Optimal extraction conditions calculated by response surface methodology (RSM) for carnosic acid were at pressure 30MPa, temperature 46°C and CO2 flow rate 3 kg h-1.
