산수유 꽃 추출물의 항산화 활성에 키토산이 미치는 영향 = Effect of Antioxidant Activity of Cornus Officinalis Flower with Chitosan

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the antioxidant activities of the D.W., EtOH, MeOH, BuOH, and EtOAc extracts of Cornus officinalis flowers (COF), and COF extracts+Chitosan (Cs). As a result, the yield of extract showed the highest value in an D.W. extract. The total polyphenol, flavonoid, and tannin showed 98.95 mg GAE/g, 17.96 mg QE/g, and 81.26 mg TAE/g at the EtOAc extract. The COF extracts at a concentration of 1 mg/mL, the ABTS radical scavenging activity and FRAP assay indicated the hightest activity with EtOAc extract. And DPPH was high value in an EtOH extract (90.57%). We knew that the EtOAc extract is good antioxidant potential. It can be seen that these effects are due to the polyphenol and flavonoid. The addition of Cs in the extracts of COF improved the DPPH and ABTS radical scavenging activity. As the result, extracts of COF and Cs are going to be used as a nature antioxidant and antioxidants substance for functional foods.
