Sažetak
Mediterranean herbs such as carob (Ceratonia siliqua), myrtle (Myrtus communis) and mastic tree (Pistacia lentiscus) are a rich source of various bioactive compounds (BAC), of which above different phenolic compounds and pigments occupy the main place. For the isolation of these compounds from the plant matrix, various extraction methods have been anciently used. With the technology progress, new extraction techniques have been developed, such as ultrasound-assisted extraction, which has the advantages in comparison with classical extraction techniques such as less environment harms due to reduced consumption of chemicals, shorter extraction time, increased extraction efficiency and greater energy savings. The aim of this research was to determine the influence of ultrasound-assisted extraction on the yields of pigments (chlorophyll a and b as well as carotenoids) and antioxidant capacity (AC) in extracts obtained from dry carob pods, myrtle leaves and fruits, and mastic tree leaves. Successive extraction was carried out using solvents of increasing polarity (ethyl acetate, 80% acetone and 96% ethanol ; v/v) at temperature of 65 °C during 30 min. The content of chlorophyll a, chlorophyll b and carotenoids in the extracts was analyzed by the spectrophotometric method, and the AC by the ORAC method. The results of the conducted analyses showed that the highest mass fraction of chlorophyll a was determined in the ethyl acetate extracts of the mastic tree leaves (20.31 mg/100 g d.m.), followed by acetone extracts obtained from the mastic leaves (16.09 mg/100 g d.m.), myrtle leaves (8.03 mg/100 g d.m.) and myrtle berries (4.58 mg/100 g d.m.), and the lowest one was found in carob pod extracts. Chlorophyll b (14.95 mg/100 g d.m.) and carotenoids (10.45 mg/100 g d.m.) were the most abundant in acetone extracts from myrtle berries, while their lowest mass fraction was found in all carob pod extracts. The highest AC was determined in acetone extracts obtained from myrtle leaves and berries as well as mastic tree leaves, while in carob pods the higher AC was determined in ethanol extracts. In general, 80% acetone proved to be a better choice for the extraction of pigments with ultrasound-assisted extraction from different plant species and also provided extracts with the highest AC determined by the ORAC method.
