The term "natural products" spans an extremely large and diverse

range of chemical compounds derived and isolated from biological

sources. Our interest in natural products can be traced back thousands

of years for their usefulness to humankind, and this continues to the

present day. Compounds and extracts derived from the biosphere have

found uses in medicine, agriculture, cosmetics, and food in ancient and

modern societies around the world. Therefore, the ability to access

natural products, understand their usefulness, and derive applications

has been a major driving force in the field of natural product research.
