Sažetak
The use of chemical pesticides and fungicides is now severely restricted in many countries and production systems because of their adverse health and environmental effects. An alternative to chemical agents in the control of phytopathogens is the use of natural products with biological activity. A by-product of apple processing, such as the apple pomace obtained after pressing in the production of apple juice, is an excellent source of polyphenolic compounds. The polyphenolic compounds from apples in particular are recognized as compounds with potential biological activity, such as antimicrobial and antifungal activity. Although polyphenolic extracts can be obtained by a variety of methods, these methods are often expensive, time consuming and use toxic solvents. In this work, polyphenolic extract from Croatian traditional apple cultivars was obtained by the matrix solid phase dispersion (MSPD) method using ethyl lactate as an extraction solvent. The MSPD extraction method has been shown to be inexpensive, fast and requires a small amount of solvent. As for solvents, ethyl lactate is one of the GRAS (generally recognized as safe) solvents. In the extracts obtained, total polyphenols, antioxidant activity and polyphenolic profile were determined by high performance liquid chromatography (HPLC). The most represented polyphenols in the extracts analyzed were catechin, epicatechin, phloridzin and quercetin and its derivatives.
