Abstract
This study was conducted to investigate the antioxidant activity and the bioactive compounds found in 70% ethanol extracts taken from Sanguisorbae officinalis L. leaves(SO) cultivated in Korea. The extracts were tested for their total phenolic contents (TPC), total flavonoid contents (TFC), phenolic compounds, and antioxidative activities using various in vitro assay such as DPPH, ABTS radical scavenging activity, FRAP activity, and reducing power. The TPC and TFC were found to be 119.3±1.54 mg gallic acid and 59.6±1.43 mg rutin at mg of 70% ethanol extracts, respectively. Catechin was the major material among the phenolic compounds in SO extracts. The DPPH radical scavenging activity, ABTS radical scavenging activity, FRAP activity, and reducing power of SO extracts were increased in a dose-dependent manner. These results suggest that SO extracts could be considered as a good source of natural ntioxidants and functional food ingredient.
