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.

Lamium orientale E.H.L. Krause is a herbaceous annual plant species in the Lamiaceae family. In the present study, anticancer, antioxidant, antibacterial, enzyme inhibitory, and quorum sensing inhibitory (on the inhibition of biofilm formation and violacein pigment production) activities of infusion and methanol (MeOH) extracts of roots, stems, leaves, and flowers of L. orientale were evaluated. The total phenolic-flavonoid contents and the phytochemical profiles of the extracts were determined using colorimetric assays and high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS), respectively. The leaf extracts had the maximal levels of flavonoids and phenolics. Chlorogenic acid was most concentrated in the extracts. Based on several antioxidant activity assays, the MeOH extract of the flowers and infusion extract of the leaves had potent antioxidant activities. The MeOH extract of the stems exhibited the highest activities against acetylcholinesterase and butyrylcholinesterase, while the MeOH extract of the roots demonstrated the highest activities against tyrosinase, amylase, and glycosidase. The highest anticancer activity was determined for the MeOH extract of the roots against the MCF-7 cells (IC50=425.7 µg/mL). The MeOH extract of leaves and all infusion extracts significantly inhibited biofilm formation in Pseudomonas aeruginosa. The results suggested that L. orientale extracts may have significant potential for developing new therapeutic approaches owing to their high content of bioactive molecules.
