Nutraceuticals are numerous and have been studied intensely for basic science and applied research. The term is generally used to refer to those chemicals that may have biological significance, for example, antioxidants, disease resistance, and regulate the immune systems, but are not established as essential nutrients. It utilizes traditional and rapidly advancing analytical methods and instrumentation such as differential solvent extraction, gas or liquid chromatography coupled with tandem mass spectrometry, nuclear magnetic resonance and electron-spin resonance, and gene and protein arrays for fractionation, purification, chemical and genetic fingerprinting, derivatization, modification, and synthesis. The goal of this special issue is to provide a platform for scientists all over the world to promote, share, and discuss various new issues and developments in the area of Nutraceuticals research.

We invite front-line researchers to submit original research articles as well as review articles that will stimulate continuing efforts to functional roles of Nutraceuticals as bioactive food components.

Potential topics include, but are not limited to:

• Natural products
• Fractionation and isolation
• Chemical and biological identification
• Functional foods
• Drug development and formulation
