In vitro enzyme inhibitory properties, antioxidant activities, and phytochemical profile of Potentilla thuringiaca
Scopus
Toplam 432 atıf DOI
The genus Potentilla is interesting for the pharmaceutical field due to its valuable medicinal properties, which have been observed in complementary and alternative medicine. In recent years, studies conducted to estimate the biological activity of several of the Potentilla species have shown a wide spectrum of therapeutic properties. In particular, in the present paper, different extracts obtained from the herb P. thuringiaca were analysed for antioxidant and enzyme inhibitory activities. The UHPLC-DAD-MS3 hyphenated techniques reported herein allow for the identification of phytoconstituents. The analyses showed the presence of flavonoids and ellagitannins as major components. Furthermore, the data demonstrated that the analysed extracts revealed a high total antioxidant capacity in the phosphomolybdenum assay. The free radical scavenging activity of the extracts was evaluated using DPPH and ABTS assays. The reducing power activity of P. thuringiaca was also determined by FRAP and CUPRAC assays, as well as metal chelating activity. In addition, the total extracts and the different fractions of P. thuringiaca revealed potent inhibitory activities against α-amylase and α-glucosidase, AChE, tyrosinase and lipase. Surprisingly, no activity against BChE was shown. P. thuringiaca could be a valuable natural source of antioxidants with interesting inhibitory actions against the key enzymes involved in several human diseases, and could represent a valid starting point for the development of new treatment and management strategies, including its use as a food supplement.

The study aimed to explore the chemical composition and assess the wide-ranging biological effects of Cachrys cristata extracts, including ethyl acetate, ethanol, ethanol/water (70%), and water. We evaluated the bioactive potential of these extracts by different chemical techniques such as radical scavenging, reducing power, and metal chelation assays. Additionally, we conducted enzyme inhibition assays to target cholinesterase, tyrosinase, amylase, glucosidase, elastase, collagenase, and hyaluronidase. In the profile analysis, we determined that the main components are phenolic acids, mainly caffeic acid with the highest concentrations. The water extract of the plant showed the highest concentration of phytochemicals and superior antioxidant activity. In addition, the ethanol and ethyl acetate extracts showed the greatest level of inhibition of most of the evaluated enzymes. On the other hand, its potential protective effects against UV-induced oxidative stress, genotoxicity, and extracellular matrix (ECM) degradation were investigated. Different extracts of the plant were evaluated in terms of their effects on DNA damage, cellular viability, ECM enzymes, and matrix metalloproteinases (MMPs). COMET analysis showed that DNA breaks and genotoxicity caused by UV rays were significantly suppressed, especially by the water extract. Furthermore, network pharmacology analyses, in conjunction with in silico molecular docking and molecular dynamics simulations, demonstrated robust ligand–protein interactions and furnished insights into the underlying mechanisms, thereby substantiating the plant's therapeutic potential. Overall, our research highlights the significant potential of C. cristata as a valuable reservoir of bioactive chemicals that can be utilized in the health and wellness industries.
