A method for making a soapbark tree permeate rich in polyphenols, useful as an antioxidant composition, comprising the steps of:

• extracting saponins, polyphenols and polysaccharides from soapbark tree to form a soapbark tree extract:
• forming a soapbark tree permeate by removing saponins from the soapbark tree extract, the soapbark free permeate being rich in polyphenols.

A method for making an antioxidant composition comprising soapbark tree polyphenols, the antioxidant composition, obtained, as a permeate from an extract of Quillaja saponaria Molina, wherein the extract of Quillaja saponaria Molina comprises quantities of saponin, polyphenol, and polysaccharide, wherein the permeate comprises an enriched quantity of polyphenols and polysaccharides in comparison to the quantity of polyphenol in the extract, and a reduced quantity of saponin in comparison to the quantity of saponin in the extract.
