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.

Studies evaluating the chemical constituents and pharmacological potential of Paracaryum species (family Boraginaceae) were limited. The current study was designed to investigate, for the first time, the chemical profile, antioxidant, enzyme-inhibitory, and cytotoxic properties of P. hedgei Aytaç & R.R. Mill. Roots extracts recorded the highest total phenolic content (24.72–91.16 mg GAE/g). About 33 compounds were identified, and the aerial parts extracts were dominated by rosmarinic acid, rutin, and sagerinic acid. In general, the root extracts exhibited greater antioxidant activity than the extracts from the aerial parts. Among the solvents, The 70 % EtOH extract of roots showed the highest antiradical (DPPH: 207.90 mg TE/g; ABTS: 238.08 mg TE/g), ion-reducing (FRAP: 384.99 mg TE/g; CUPRAC: 615.27 mg TE/g), and total antioxidant activities (3.21 mmol TE/g), whereas the EtOAc and aqueous extracts from the aerial parts demonstrated the best chelating capacity. The enzyme inhibition varied according to the plant parts examined and the solvents employed for extraction. The EtOAc extract of the roots exerted the highest inhibitory effect towards the human carbonic anhydrase II (IC50: 2.32 μg/ml). The cytotoxicity of the extracts was tested against three cancer cell lines (HELA, A549, and HCT-116) and one healthy cell line (HEK-293). Specifically, the EtOAC extracts showed cytotoxic effects on HELA cells sourced from aerial parts (IC50: 106.30 μg/ml) and on HCT-116 cells sourced from roots (IC50: 96.82 μg/ml). Molecular docking results provided additional support for the enzyme inhibition capabilities of the extracts. Combined network pharmacology and molecular docking analyses revealed that phenolic acids from P. hedgei exert anti-cancer effects on cervical and colorectal adenocarcinoma by modulating key pathways, including retinoic acid metabolism, steroid biosynthesis, and inflammatory responses. These findings can provide a scientific starting point for the pharmaceutical potential of P. hedgei , and it can be considered a valuable source of natural bioactive compounds for functional nutraceutical and pharmaceutical applications.
