Green synthesis of new and natural diester based on gallic acid and polyethylene glycol.

Background: Antioxidant polyphenols like gallic acid (GA) and its esters called "gallates", which have health advantages for humans, have grown in significance in maintaining a healthy lifestyle and eating a significant amount of secondary plant phytochemicals. Here, for the first time, we suggest a green synthesis of a brand-new, all-natural diester based on gallic acid and polyethylene glycol.

Methods: This di-gallate is created in a single step without the use of a solvent (solid-solid reaction).
