Abstract: | Various species of the genus Phlomis have been reported to produce metabolites demonstrating significant pharmacological efficiency. In mature summer leaves of Phlomis fruticosa several secretory cells and structures were detected. A spectrum of compounds was localized histochemically within them. Calluses produced from leaf-cell cultures were histochemically investigated as well. Callus cells, although of low-differentiation, are synthetically active and produce various compounds. Many of them could be of pharmaceutical interest. |
