Secondary metabolite contents of W. somnifera varied remarkably between seasons and genotypes under ex vitro condition. In vitro studies provide an optimum culture condition for steady and quality production of bioactive chemicals throughout the year without involvement of environmental stresses. Mass production of micro-shoots and plantlets by exploring the organogenic totipotency of shoot tip explants (ex vitro and in vitro grown) considering two elite genotypes (Poshita and Jawahar 22) of W. somnifera, and assessment of their capability in production and accumulation of bioactive metabolites (total alkaloid and withanolides amount were quantified; withanolide A and withaferin A contents were estimated by High Performance Liquid Chromatography-HPLC).
