What is pharmacognosy and Phytochemistry?

Pharmacognosy the branch involved with healthful medicine obtained from plants or alternative natural sources. Phytochemistry is in the study of phytochemicals in plants and other natural sources. Phytochemicals are chemicals derived from plants.

How is pharmacognosy related to botany?

is that pharmacognosy is a branch of pharmacology that studies medical substances that are derived from natural sources, and their recognition while botany is (uncountable) the scientific study of plants, a branch of biology typically those disciplines that involve the whole plant.

What is the significance of Phytochemistry in pharmacognosy?

The Phytochemistry is very important for the determination of the active ingredients of medicinal plants, their quantification and analysis of the beneficial and harmful effects to human health.

Which drugs are in pharmacognosy?

Pharmacognosy deals with the natural drugs obtained from organisms such as most plants, microbes, and animals. Up to date, many important drugs including morphine, atropine, galanthamine, etc. have originated from natural sources which continue to be good model molecules in drug discovery.

Who is father of pharmacognosy?

Dioscorides
Dioscorides, known as the father of pharmacognosy, was a physician in military and a pharmacognosistin Nero’s Army and wrote on drugs of plant origin. In AD 77, he wrote “De MateriaMedica,” elaborating on large data about helpful medicinal plants [17, 18].

What is the role of pharmacognosy?

Pharmacognosists (practitioners of pharmacognosy, typically trained to PhD level) have made many important contributions to their science, including the preparation of monographs for the identification of drugs of natural origin, the discovery and chemical characterisation of biologically active constituents of drugs …

Why do we need to study pharmacognosy?

Pharmacognosy is used by pharmaceutical companies to screen, characterize and produce new drugs for the treatment of human disease. Often, naturally occurring drugs cannot be mass-produced, so they must be studied in order to develop synthetic biosimilars.

What is the importance of Phytochemistry?

Phytochemistry is the study of phytochemicals, these are secondary metabolic substances found in plants. Phytochemistry is widely used in the field of herbal medicine. It paves the way to discovery of new therapeutic compounds as needed by the modern scientific approach to producing medicines.

What is an example of a phytochemical?

A few examples of well-known phytochemicals are the flavonoids, phenolic acids, isoflavones, curcumin, isothiocyanates, and carotenoids. The many phytochemicals in common plant foods, herbs, and spices represent a broad range of chemical compounds.

What are natural drugs?

The most dominant natural medicine source is plants, due to their chemical and structural diversity and the biodiversity of their components. Examples of medicines that are derived from plants are aspirin (from willow tree bark) (2), digoxin (from the flower, Digitalis lanata) (3) and morphine (from opium) (4).

What do you need to know about pharmacognosy and phytochemistry?

How did pharmacognosy help in the discovery of drugs?

• Pharmacognosy helped to improve plant chemistry (phytochemistry) significantly with the knowledge of extraction. Variety of chemical constituents that are accumulated and synthesized by plants have revolutionized the process of natural drug discovery.

What is the study of drugs of natural origin?

In times of yore, pharmacognosy was considered as the study of drugs of natural origin. The American Society of Pharmacognosy derived it as the study of physical, chemical, biochemical and biological properties of drug, drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources.

What is the meaning of the term pharmacognosy?

The term ‘pharmacognosy’ (combination of two Greek words i.e., pharmakonmeans drug and gnosismeans knowledge) means “acquiring knowledge of drugs” was coined in 1815 by C. A. Seydler, German medical student in his thesis title “Analyetica Pharmacognostica”.
