Preserving the Free-Radical Scavenger Activity of Key Bioactives During Extraction and Purification Processes
We extracted and purified by preparative chromatography several polyphenols from Scutellaria Baicalensis. Then we confirmed their antioxidant activity by testing the DPPH free radical scavenging capabilities of each compound. We found out Baicalin is a powerful antioxidant whereas Wogonin and Oroxylin A are ineffective.
