Withanolide composition and in vitro culture of Italian Withania somnifera.
From Italian plants of Withania somnifera six withanolides were isolated, whose structures allowed us to assign the Italian race of W. somnifera to the Israel chemotype III. In vitro cultures of Italian W. somnifera under different conditions were obtained, as well as infection by agrobacterium rhizogenes. HPLC analysis of IN vitro derived tissues showed low contents of withanolides.
