Effect of phytohormones on shoot apex and leaf explants of Withania somnifera (Ashwagandha)

Withania Somnifera (ashwagandha)—an Important Medicinal Plant

Induction and identification of autotetraploidy in ashwagandha (Withania somnifera Dunal.)

Seed treatment with aqueous colchicine solution was carried out for induction of autotetraploidy in ashwagandha in four accessions (Shilpa, Acc. 17, Bydyanath and MWS-327). Increased stomatal size and decrease in stomata density aided in detection of autotetraploids. Among four ashwagandha accessions tried, Acc. 17 was more responsive for the induction of autotetraploids. Colchicine at 0.5 per ...

Green synthesis and characterization of gold nanoparticles using leaf extracts of Withania somnifera (Linn.) (Ashwagandha)

In this study, a novel technique for biosynthesizing of gold nanoparticles (GNPs) using Withania somnifera as reductants and stabilizers is reported. Biosynthesis of anisotropic gold nanoparticles using ethanolic extract of Withania somnifera leaf and their potential as IR blockers has been demonstrated. The phenolic groups (–OH) residue was identified as the active functional group for gold io...

Withania somnifera (Ashwagandha): a novel source of L-asparaginase.

Different parts of plant species belonging to Solanaceae and Fabaceae families were screened for L-asparaginase enzyme (E.C.3.5.1.1.). Among 34 plant species screened for L-asparaginase enzyme, Withania somnifera L. was identified as a potential source of the enzyme on the basis of high specific activity of the enzyme. The enzyme was purified and characterized from W. somnifera, a popular medic...

P01.44. In vivo immune modulating effects of Ashwagandha (Withania somnifera)

Purpose The herb Ashwagandha (Withania somnifera, Dunal), has been used for centuries in Ayurveda as rasayana – promoter of longevity, well-being, and disease prevention. Traditional use combines the herb with a carrier substance called “anupana,” believed to help aid in bioavailability and absorption. To compare the effects of Ashwagandha root extract plus anupana on human immune activation to...
