Pharmacognosy is the study of plants or other natural sources as a possible source of drugs. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical, and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources. The Pharmacognosy & Phytochemistry Laboratory is used for morphological and microscopical studies of medicinal herbs and plant materials, to classify plant material components by conducting chemical tests.
Sufficient numbers of equipments, glasswares, chemical reagents are existed in this lab for easy going of Pharmacognosy I & II lab courses. Different phytochemistry research are also performed in this lab. The Pharmacognosy I laboratory is intended for conducting study of some medicinal plants, identification of plant leaves, their botanical name, nature and medicinal uses, qualitative tests of sugars (glucose, fructose, galactose, maltose, pantose, sucrose etc). In addition, Pharmacognosy II lab is designed to conduct pharmacognostic study of a few selected powdered drugs, extraction and isolation of caffeine from tea, coffee; analysis of plant extracts by thin layer chromatography, study of volatile oils and some volatile-oil containing drugs: caraway, clove, cinnamon, peppermint etc; study of few important cardioactive drugs: digitalis, strophanthus and squill, study of alkaloids and some alkaloid-containing drugs: belladonna, strammonium, cinchona, rauwolfia, tea, coffee, tobacco, ergot, ephedra, nux vomiica and areca.
