MP and MPM that contain protoalkaloids and tropane alkaloids
Biological Effect and Application of Alkaloids Alkaloid-bearing plants are used in Pharmacy and Medicine with different purposes. They are used directly at the Chemist’s shops for manufacturing of extracts and decoctions (thermopsis – Thermopsis Lanceolata). The others are used for manufacturing galenicals tinctures, extracts, neogalenicals. Alkaloids are produced from raw stuff in pure form and then manufactured as: tablets, ampoules, drage. Medical significance of alkaloids: • analgetics (Poppy remedies) • hemostatics (Claviceps purpurea medicines ) • cardiovascular remedies (ephedra) • anticancer (autumn crocus remedies ) • spasmolytic (beladonna). It is not possible to describe all types of phamacological effects. Effects of some alkaloids on the human body are studied well. These substances effect on specific receptors or influence enzyme activity.
