Open Access Toplam 345 atıf DOI
In this work, the biological and chemical fingerprints of three extracts (ethyl acetate, methanol, and water) from two Potentilla species (Potentilla reptans and P. speciosa) were investigated. Antioxidant, enzyme inhibitory, and cytotoxic activities were performed for the biological fingerprint. For the chemical characterization, total bioactive components, and individual phenolic components were determined using photometric and HPLC methods, respectively. The main identified phenolic compounds in these extracts were rutin and catechin. Methanol and water extracts contained the highest total phenolic and flavonoid content. The results of antioxidant assays showed that methanol and water extracts displayed higher antioxidant activity compared to the ethyl acetate extract. Generally, methanol and water extracts exhibited higher biological activities correlated with higher levels the bioactive components. For P. speciosa, the methanol extract exhibited the highest enzyme inhibitory activity (except BChE inhibitory activity). P. reptans exhibited also high antiproliferative activity against MCF-7 cells whilst P. speciosa had weak to moderate activity against both of A549 and MCF-7 cell lines. The results suggest that Potentilla species could be potential candidates for developing new phyto-pharmaceuticals and functional ingredients.

The influence of drying and extraction processes on the phytochemical composition and biopotential of elderberry is challenging for the food industry. For this reason in this research two drying techniques (lyophilization and natural convection) and three extraction techniques (ultrasound (UAE), microwave (MAE), and conventional (maceration (MAC)) was applied using two”green” solvents (water and 50 % ethanol). Results of the research showed that lyophilization was a better way of drying than natural convection, while MAE extraction was the most efficient technique for the isolation of secondary metabolites. The most abundant phenolic compounds established by LC-MS/MS analysis, were chlorogenic acid and rutin, identified in extracts of lyophilized elderberries. Elderberry extracts achieved great antioxidant (CUPRAC: 2.30–5.13 mg TE/mL) and enzyme inhibitor potential (α-amylase: 0.51–8.34 mg ACAE/mL). The results suggest that elderberry is a rich natural source of bioactive compounds and could be used for the future development of dietary supplements and functional foods.
