Pharmacognosy Research

March 4, 2013

Introduction:

Pharmacognosy is the study of medicines that they are derived from natural sources. Simply the basic study of Drugs is called Pharmacognosy. The word “pharmacognosy” is derived from the Greek words φάρμακον pharmakon (drug), and γνῶσις gnosis (knowledge). Simply the knowledge about drugs is called pharmacognosy.  The term “pharmacognosy” was used for the first time by the Austrian physician Schmidt in 1811 and 1815 by Crr. Anotheus Seydler in a work titled Analecta Pharmacognostica.

An image showing the natural productsOriginally—during the 19th century and the beginning of the 20th century—“pharmacognosy” was used to define the branch of medicine or commodity sciences (Warenkunde in German) which deals with drugs in their crude, or unprepared, form.

As late as the beginning of the 20th century, the subject had developed mainly on the botanical side, being particularly concerned with the description and identification of drugs both in their whole state and in powder form. Such branches of pharmacognosy are still of fundamental importance, particularly for pharmacopoeial identification and quality control purposes, but rapid development in other areas has enormously expanded the subject.

According to the American Society of Pharmacognosy, pharmacognosy is “the study of natural product molecules (typically secondary metabolites) that are useful for their medicinal, ecological, gustatory, or other functional properties”.

The name specifies Phytochemistry is in the strict sense of the word the study of phytochemicals. These are chemicals derived from plants. In a narrower sense the terms are often used to describe the large number of secondary metabolic compounds originate from plants. Many of these are known to provide protection against insect attacks and plant diseases. They also exhibit a number of protective functions for human consumers. The common techniques that are used in the field of phytochemistry are extraction, isolation and structural elucidation (MS,1D and 2D NMR) of natural products, as well as various chromatography techniques (MPLC, HPLC, LC-MS).

Being an active member of Science world, OMICS Publishing Group is now inviting all the people around the world to attend the “International Conference & Exhibition on Pharmacognosy, Phytochemistry & Natural Products”. Pharmacognosy-2013 will be held during 21-23 October in Hyderabad, India.
