withanolide a/withania somnifera

Withanolide A is a biologically active secondary metabolite occuring in roots and leaves of Withania somnifera. In the present study, adventitious roots from leaf explants of W. somnifera were induced for the production of withanolide-A by Agrobacterium tumefaciens strain C58C1 to obtain hair roots.

Multiple shoot cultures of two experimental lines of Withania somnifera plants (RS-Selection-1 and RS-Selection-2) were established using nodal segments as explants. The hormonal combinations of benzyl adenine and kinetin not only influenced their morphogenetic response but also differentially

Endophytes have been reported from all plant species from different parts of tissue including root, stem and leaves. Here we report, three fungal endophytes, Aspergillus terreus strain 2aWF (2aWF), Penicillium oxalicum strain 5aWF (5aWF), and Sarocladium kiliense strain 10aWF (10aWF) from Withania

Background: Both the roots and leaves of Withania somnifera are products of commerce. They contain active compounds of therapeutic value and mostly different withanolides. Several pharmacological activities of W. somnifera have links to one or more withanolides. The presence of phenolic compounds in

Leaves of Withania somnifera contained more withaferin A and withanolide A than roots indicating that these compounds mainly accumulate in leaves. With an increase in age of the plant, withaferin A was enhanced with a corresponding decrease in withanolide A. Hairy root cultures were induced from

Withania somnifera (L.) Dunal. (Indian ginseng) is an important medicinal plant which yields pharmaceutically active compounds, namely withanolides. This study deals with the optimisation of the adventitious root suspension culture of W. somnifera for the production of biomass and withanolide-A. We

The aim of this study was to investigate the effect of Withania somnifera (WS) extract, withanolide A (WA), and carbamazepine (CBZ) on cerebellar AMPA receptor function in pilocarpine-induced temporal lobe epilepsy (TLE). In the present study, motor learning deficit was studied by rotarod test, grid

In the present study we investigate the effect of Withania somnifera (WS) root extract and Withanolide A (WA) in restoring spatial memory deficit by inhibiting oxidative stress induced alteration in glutamergic neurotransmission. We demonstrate significant cellular loss in hippocampus of epileptic

Alzheimer's disease (AD) is characterized by progressive dysfunction of memory and higher cognitive functions with abnormal accumulation of extracellular amyloid plaques and intracellular neurofibrillary tangles throughout cortical and limbic brain regions. Withania somnifera (WS) also known as

The effects of graded doses of a chemically standardized aqueous alcoholic (1:1) root extract (AGB) of Withania somnifera on the immune system of SRBC immunized BALB/c mice were investigated. Mice were administrated AGB orally for 15 days. AGB stimulated cell mediated immunity, IgM and IgG titers

Ashwagandha (Withania somnifera Dunal., Solanaceae) is one of the most reputed medicinal plants of Ayurveda, the traditional medical system. Several of its traditionally proclaimed medicinal properties have been corroborated by recent molecular pharmacological investigations and have been shown to

This work deals with optimisation of adventitious root suspension culture of Withania somnifera (L.) Dunal (Solanaceae) for the production of biomass and withanolide A and we investigated the effect of carbon source and the initial medium pH on growth and production of withanolide A in adventitious

Cell suspension cultures of Withania somnifera were established in shake flasks and the effect of different growth regulators (auxins, combination of auxin and cytokinin), inoculum density (2.5-20 g L(-1)), different media (MS, B5, NN and N6), the strength of the MS medium (0.25-2.0 x), carbon

Withania somnifera (WS) is one of the popular botanical medicines widely used in Ayurveda. Withanolides such as withaferin A (WA) and withanolide A (WLD) are its bioactive constituents reported as promising drug candidates in cancer and neurological disorders respectively. A new, selective and rapid

In the present study, root cell suspension cultures of W. somnifera were elicited with mycelial extract (1% w/v) and culture filtrate (5% v/v) of their native endophytic fungus Aspergillus terreus 2aWF in shake flask. Culture filtrate of A. terreus 2aWF significantly elicits withanolide A at 6H
