Herbal medicines are the oldest remedies known to mankind. The traditional herbal medicines and their preparations have been widely used in China as well as in southeastern Asian and western countries for thousands of years. Additionally, nutrition supplements became popular recently. Many analysis-based studies regarding chemical and quality control research have been conducted in the past 20 years. But quality and safety have always been a big issue puzzling the development of natural medicines.

We invite investigators to contribute original research articles as well as review articles concerning the development, improvement, validation, and/or extension of application of analytical methodology in the natural medicine sciences and nutrition supplements. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bioscreening), extraction, separation, purification, identification, and quantification of compounds in biochemistry, cellular and molecular biology, biotechnology of natural medicines, the health food sciences, and agriculture. Potential topics include, but are not limited to:

• Advances in natural product and nutrition supplement analytical technologies
• Recent advances in biochemistry research of natural medicines and nutrition supplement
• Innovations in analytical chemistry of natural products and nutrition supplement
• Developments in analytical methods of medicinal plants and nutrition supplement
• Ethnobotanical drug discovery
• Metabolism of natural products
• Safety, efficacy, and consistency of natural medicines
• Quality control and evaluation of Chinese materia medica and finished products
• Detection of low quality and adulterants of natural product
• Identification of the plant by various analytical techniques
