Abstract
Designing new forms of food, food additives, and nutraceuticals is necessary due to the growing needs of consumers, as well as the inflammation of civilization diseases, the prevention and treatment of which can be significantly supported by dietary intervention. For this reason, this study aimed to obtain highly bioactive preparations in the form of powders from the fruits, leaves, and flowers of six species of hawthorn (Crataegus L.) using solid phase extraction (SPE). Ultra-performance liquid chromatography analysis (UPLC-PDA-MS/MS) showed a high concentration of phenolic compounds (in the range from 31.50 to 66.06 mg/g), including the highest concentration in hawthorn fruit preparations. Fruit preparations also showed the highest antioxidant activity (through scavenging of O(2)˙(-) and OH˙ radicals), antidiabetic activity (inhibition of α-amylase and α-glucosidase), and anticancer activity, mainly against colon cancer cells (Caco-2). At the same time, hawthorn flower preparations showed the highest biocompatibility against normal colon cells (CCD841CoN) and anti-inflammatory activity (trypsin inhibition). Correlation and principal component analysis (PCA) showed that the health-promoting potential was most influenced by the content of falavan-3-ols. The above findings provide a basis for the industrial use of the developed preparations, which is in line with the current trend in food technology related to the search for new sources of bioactive compounds and the design of highly bioactive food.
