Antioxidant and anti-inflammatory activity of Potentilla reptans L.
Potentilla species have been used in traditional medicine in the treatment of different ailment, disease or malady. Potentilla reptans (P. reptans) has been scarcely studied. The aim of this study was to test antioxidant and anti-inflammatory activity of P. reptans aerial part and rhizome. DPPH assay was used to measure antioxidant activity of aqueous plant extracts. Anti-inflammatory effect wa...
متن کاملCarbon gain in the competition for light between genotypes of the clonal herb Potentilla reptans
1. Different views exist as to what traits will lead to dominance when plants compete for light. One view is that taller plants with better relative positions in the canopy will exclude shorter plants because they intercept almost all light and thus can achieve a higher carbon gain. Alternatively, resource competition models predict that plants that are capable of positive net photosynthesis at...
متن کاملTesting for disconnection and distance effects on physiological self-recognition within clonal fragments of Potentilla reptans
Evidence suggests that belowground self-recognition in clonal plants can be disrupted between sister ramets by the loss of connections or long distances within a genet. However, these results may be confounded by severing connections between ramets in the setups. Using Potentilla reptans, we examined severance effects in a setup that grew ramet pairs with connections either intact or severed. W...
متن کاملRoot Foraging Increases Performance of the Clonal Plant Potentilla reptans in Heterogeneous Nutrient Environments
BACKGROUND Plastic root-foraging responses have been widely recognized as an important strategy for plants to explore heterogeneously distributed resources. However, the benefits and costs of root foraging have received little attention. METHODOLOGY/PRINCIPAL FINDINGS In a greenhouse experiment, we grew pairs of connected ramets of 22 genotypes of the stoloniferous plant Potentilla reptans in...
متن کاملAntioxidant Activity and Cardioprotective Effect of Potentilla reptans L. via Ischemic Preconditioning (IPC)
Background and objectives: Potentilla reptans L. from Rosaceae family is used as traditional medicine in Iran and other countries. Previous investigations on Potentilla species have reported strong antioxidant activity and cardioprotective effect. In this study, antioxidant activity of aerial parts and root of Potentilla reptans, and...
متن کاملCytotoxic and Enzyme Inhibitory Potential of Two Potentilla species (P. speciosa L. and P. reptans Willd.) and Their Chemical Composition
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 w...
