Abstract

Scopolia carniolica Jacq. is a medicinal species of Solanaceae, harvested from the Romanian spontaneous flora for its atropine and scopolamine content. We have analyzed the anatomical structure of the vegetative organs (rhizome, root, stem and leaf) and the biometrical parameters of the leaf blade (vascular islet, stomatal index and palisade ratio), in order to establish the main specific characters and differential elements useful for the correct identification and for avoiding the impurification of medicinal products. The characteristic structures for the rhizome and root are the secondary ones, mainly with parenchyma elements and lacking in mechanical fibres; the stem has a primary becoming secondary structure, bicolateral vascular bundles with cambium in the interior and between them and endoderma as starch layer. The sand cells are characteristic for rhizome, root and stem structures. On the leaf surface were identified protector multicellular trichomes and specific secretory and glandular ones.
