American Society of Pharmacognosy
The American Society of Pharmacognosy (ASP) is a scientific society that promotes the growth and development of pharmacognosy
Pharmacognosy is the study of medicines derived from natural sources. 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...

 through presentation of research achievements and publication of meritorious research.

ASP was founded in 1959 as an outgrowth of the Plant Science Seminar established in 1923. ASP currently has over 1,100 active and associate members. Appromimately 40 percent of the active members reside outside the U.S. and Canada and represent more than 60 countries throughout the world.

Pharmacognosy includes 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. Research problems in pharmacognosy include studies in the areas of phytochemistry
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 found in plants. Many of these are known to provide protection against...

, microbial chemistry, biosynthesis
Biosynthesis is an enzyme-catalyzed process in cells of living organisms by which substrates are converted to more complex products. The biosynthesis process often consists of several enzymatic steps in which the product of one step is used as substrate in the following step...

, biotransformation
Biotransformation is the chemical modification made by an organism on a chemical compound. If this modification ends in mineral compounds like CO2, NH4+, or H2O, the biotransformation is called mineralisation....

, chemotaxonomy
Chemotaxonomy , also called chemosystematics, is the attempt to classify and identify organisms , according to demonstrable differences and similarities in their biochemical compositions. The compounds studied in most of the cases are mostly proteins, amino acids and peptides...

ASP publishes the quartery ASP Newsletter and co-publishes the Journal of Natural Products with the American Chemical Society
American Chemical Society
The American Chemical Society is a scientific society based in the United States that supports scientific inquiry in the field of chemistry. Founded in 1876 at New York University, the ACS currently has more than 161,000 members at all degree-levels and in all fields of chemistry, chemical...
