The ethanolic crude extract of Valeriana wallichii rhizome (VwR.Cr) was studied in vitro for its possible antispasmodic activity to rationalize some of its folkloric uses. Segments of 2-3 cm long of rabbit jejunum preparations were mounted in Tyrode’s solution and aerated with 95% oxygen in carbon dioxide. Isotonic responses were measured on Bioscience oscillograph. VwR.Cr caused a dose-depende...

Both soil nematodes and microorganisms have been shown to be sensitive bioindicators of soil recovery in metal-contaminated habitats; however, the underlying processes are poorly understood. We investigated the relationship among soil microbial community composition, nematode community structure and soil aluminum (Al) content in different vegetated aluminum-rich ecosystems. Our results demonstr...

In vitro propagation method was developed for obtaining large number of plantlets of Valeriana wallichii DC. (Valerianaceae), an indigenous high value medicinal and aromatic plant species of Indian Himalayan region, using nodes of in vitro grown seedlings. High frequency shoot proliferation was induced in explants cultured on Murashige and Skoog (MS) medium supplemented with different concentra...
