Gamhongro-ju is a Korean traditional alcoholic beverage made from medicinal herbs and spices. In this study, polyphenol content and antioxidant activities of gamhongro-ju and the 8 individual herb extracts used to make the beverage were determined. Cinnamon, saposhnikovia root, clove, ginger, violet-root cromwell, licorice, citrus peel and logan (2.5 g each) were extracted with 1000 ㎖ of 45% and 60% purified ethanol (PE), and 45% traditionally distilled ethanol (TDE). The individual herb (20 g each) was extracted with 1000 ㎖ of 60% PE. Polyphenol content, DPPH and ABTS radical scavenging activities of the extracts were measured. In the combined herb extracts, polyphenols were significantly higher in the 45% and 60% PE extracted for 90 days than those for 30 days. In the 8 individual herb extracts, the clove extract had the highest polyphenol content (2421～2446 ㎎/ℓ). ABTS IC50 values of the combined herb extracts were lower in the 60% PE and 45% TDE extracted for 90 days than those for 30 days. In the 8 individual herb extracts, the clove and cinnamon had the lowest ABTS and DPPH IC50 values. In the individual extracts, ginger had the lowest polyphenol content; however, it was the third in the antioxidant activity.
