Emerging green technologies for the chemical standardization of botanicals and herbal preparations

• Emerging green approaches for the chemical standardization of medicinal plants.
• Recent development of extraction technologies that eliminate use of solvents.
• Solvent-free techniques for analysis of constituents in botanical extracts.

As botanicals and many medicinal plants can be processed to become a food or a health supplement, a drug or cosmetics, chemical standardization is important for their quality control. Hence, the selection of appropriate extraction technologies and analytical techniques is required to provide a solvent-free solution for the chemical standardization of botanicals and herbal preparations.
