Ultrasound-assisted extraction of bioactive compounds from white cherry (Prunus avium L. starks gold) fruit and determination of their properties

This study focused on the bioactive components of white cherry (Prunus avium L. starks gold) and assessed the bioactive properties of extracts obtained through ultrasound-assisted extraction using methanol, ethanol, and hexane. Methanol extracts were found to have the highest total phenolic content (1.3-4.0 mg GAE/g) and antioxidant activity, with antioxidant values ranging from 2.34-22.33 mM TE/g extract according to DPPH and 0-1.45 mM TE/g extract according to the FRAP method. In enzyme analyses evaluating potential effects on diabetes, the extracts inhibition effects on α-glucosidase and α-amylase enzymes were measured, with ethanol extracts showing the highest inhibition values (35.05 mg/mL for α-glucosidase and 90.1 mg/mL for α-amylase). Additionally, methanol extracts exhibited significant antibacterial activity against Escherichia coli and Staphylococcus aureus, while ethanol extracts showed lower activity, only against E. coli. These findings suggest that white cherry extracts possess various bioactive properties, particularly in terms of antioxidant activity and potential effects on diabetes.
