Unveiling the Therapeutic Potential of Crataegus pseudoheterophylla Pojark.: Enzyme Inhibitory and Antioxidant Properties
Abstract
Different parts of Crataegus (Rosaceae) species have traditionally been used to treat various diseases. Although there are biological activity studies on these species, research on Crataegus pseudoheterophylla Pojark. is quite limited. This study evaluated the antioxidant, anti-obesity, and antidiabetic activities of the methanolic leaf extract of C. pseudoheterophylla. Enzyme inhibition tests (α-glucosidase, pancreatic lipase, and α-amylase) were used to investigate anti-obesity and antidiabetic effects. In this study, the total phenol (83.60 ± 2.63 mg GAE g-1 extract) and total flavonoid (39.42 ± 0.71 mg QE g-1 extract) contents of the extract were also determined by ultraviolet (UV) spectroscopy. Research results showed that the extract had strong 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity with an inhibition of 82.88 ± 0.35%. Although the extract inhibited pancreatic lipase, the effect was weaker than that of orlistat (48.25 ± 1.10% vs. 61.75 ± 2.87%, respectively). The extract showed strong α-glucosidase and moderate α-amylase enzyme inhibitory activity (IC50 values were 56.9 ± 0.87 µg mL-1 and 153.8 ± 12.40 µg mL-1, respectively). In this context, it was determined that C. pseudoheterophylla leaves exhibited strong antioxidant and α-glucosidase inhibitory activity and a moderate α-amylase inhibitory effect. It was concluded that further studies on the extract would be important in identifying new compounds with antioxidant and α-glucosidase inhibitory effects.
