Previous studies of transgenerational plasticity have demonstrated that long-term overgrazing experienced by Leymus chinensis, an ecologically dominant, rhizomatous grass species in eastern Eurasian temperate grassland, significantly affects its clonal growth in subsequent generations. However, there is a dearth of information on the reasons underlying this overgrazing-induced memory effect in ...

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...

Lagenandra ovata (Linn.) Thw. syn. L. toxicaria Dalz. of Araceae family was evaluated for antibacterial activity against the Gram positive bacterium, Staphylococcus aureus and the Gram negative bacteria, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, P. vulgaris and Pseudomonas aeruginosa. Methanol extract of the rhizome and the oil fractions obtained from the methanol extract thro...

1. The perfoliate pondweed Potamogeton perfoliatus L. constitutes large monospecific macrophyte patches in many Central European lakes. Correlative evidence from the field suggests that P. perfoliatus is under an increasing grazing pressure during its short vegetation period fromMay to September due to seasonal outbreaks of the aquatic moth Acentria ephemerella Denis & Schiffermüller. We used a...

Phytochemical screening and their antibacterial activity of plant are important parameters which lead to the isolation of new and novel compounds. Cryptocoryne spiralis (Retz) Fischer ex Wydler var. spiralis (CSS) and Cryptocoryne retrospiralis (Roxb) Kunth (CR), leaf and rhizome have been selected for phytochemical screening to identify the different classes of secondary metabolites. Antibacte...

Curcuma angustifolia also known as ‘haledo’ is commonly found in Sikkim and has many medicinal uses and has been used traditionally since ancient ages. Its rhizome is aromatic and the solvent extract of the rhizome has free radical scavenging activity which was carried out in this study by 2,2-diphenyl-1-picrylhydrazyl DPPH. Hot methanol extract and cold methanol extract of the dried powder of ...
