Biopotential of underutilized Rosaceae inflorescences

The aim of this work was to assess the biopotential of the young inflorescence tissues of Prunus, Malus and Chaenomeles in order to evaluate the possibility of their application in the food industry, and to provide a polyphenolic fingerprint for their quality control. The contents of different bioactive compounds and their antioxidant capacities were spectrophotometrically measured, the main phenolic compounds were analysed using LC-DAD-MS, the antidiabetic potential was determined using α- amylase and α-glucosidase inhibition assays, the antiinflammatory potential was determined using a 5-lipoxygenase inhibition assay, and the cytotoxicity was determined by MTT assay. Using different statistical methods, the relations between the samples and the measured parameters were revealed. In total, 77 compounds were identified. The most effective in the inhibition of antidiabetic enzymes and anti-inflammatory 5- lipoxygenase was C. japonica. The inhibition of α- glucosidase was strongly positively correlated with the total and condensed tannins, procyanidin dimers and procyanidin tetramer, and was very strongly correlated with chlorogenic acid. In α-amUSAylase inhibition, C. japonica and P. serrulata ‘Kiku Shidare Zakura’ were equally efficient to the standard inhibitor, maltose. The most effective in the growth and proliferation inhibition of HepG2, HCT116 and HaCaT cells was P. avium. The results suggest Prunus, Malus and Chaenomeles inflorescences as functional food ingredients.
