Abstract
|
|
|
|
This research was performed to confirm the antioxidant activity of extracted Dicentra spectabilis. We conducted this study through a total polyphenol experiment, ABTS radical scavenging activity and DPPH radical scavenging activity from watersoluble chitosan with solutions of 24 hr, 48 hr and 72 hr extracts. The concentrations of total polyphenol were 13.2 mg GAE/g at 24 hr, 15.5 mg GAE/g at 48 hr and 47.2 mg GAE/g at 72 hr, respectively. Both ABTS radical scavenging activity and DPPH radical scavenging activity showed to the highest rank at 72 hr extract. The mixture of the extracted Dicentra spectabilis and Water-soluble chitosan showed much more higher antioxidant activity than only water-soluble chitosan.
