Based on the number of phenolic groups present in a molecule, phenolic compounds can be grouped as simple, bi and polyphenols. Phenolic derivatives such as hydroquinone, resorcinol, thymol, etc. have only one substituted phenolic ring and hence are simple phenols. These phenolic compounds are highly soluble in water due to the presence of single hydroxyl group, it often finds its application in disinfectants and chemical industries . Biphenols are identified by the presence of two phenolic rings. These phenols have low solubility. Bisphenol A (BPA) is a common example of bi phenols, which is found in industrial waste and is known to have adverse effects on human health . Compounds that consist of multiple units of phenolic structure are known as polyphenols; these are naturally found in plant (roots and leaves) . Flavonoids, tannins, lignin and stilbenes are few examples of polyphenols . The solubility of polyphenol is variable. Lower molecular weight polyphenols (e.g., flavonoids) are moderately soluble in water, on the other hand high molecular weight polyphenols (e.g., tannins) are poorly soluble in water and form colloidal suspension in water, however these are soluble in organic solvents such as ethanol .
