MODULE 2: GENERAL PHARMACOGNOSY (4 CFU)

Definition, aims and history of pharmacognosy. Natural substances today. Traditional medicines. Drugs in toto and principles purified.

Crude plant drugs.

Classification. Variability in the activity of a drug: natural factors (endogenous and exogenous) and artificial that lead to changes in the content and quality of active components. Techniques for the production "in vitro" of active ingredients. Vegetable principles as a starting material for hemi-synthesis and molecular models of new drugs. Preparation of herbal drugs (collection time, husking, drying, stabilization, sterilization). Conservation of plant drugs (drying, freezing, freeze-drying). Pulverization of drugs. Preparations with herbal drugs (infusions, decoctions, tisane, extracts, tinctures, syrups, juices, macerated, hydrolates, alcoholates, alcolaturi, essences. Standardization of extracts). Quality control of herbal drugs (Examination of morphological and organoleptic, chemical, physical, biological assays, toxicology). Efficacy and safety of use of preparations of medicinal plants. Chemical classification and biogenesis of active ingredients.
