Schisandra chinensis is widely known to regulate fatigue recovery, lowering blood pressure, and contains several bioactive compounds such as schizadran. In this study, we obtained basic data for the development of health food by measuring the schizandrin content, antioxidant activity, anti-inflammatory, antibacterial activity, and enzyme activity of the hot water extract (SCW) and 40% ethanol extract (SCE) of S. chinensis grown in Sunchang-gun, Korea. Schizandrin content was measured as 7.87 ± 0.01 mg/g for SCW and 10.38 ± 0.05 mg/g for SCE. SCE had higher DPPH and ABTS radical scavenging activity than SCW, and the total polyphenol and flavonoid contents were also higher. Both SCW and SCE (500 μg/mL) exhibited more than 55% protective effects against oxidative stress in HepG2 cell lines. Anti-inflammatory efficacy was assessed using RAW 264.7 and Caco-2 cells and both SCW and SCE do not have cytotoxic effects. Anti-inflammatory results showed concentration-dependent NO activity and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) inhibition. The antibacterial activity increased with increasing dose concentrations of SCW and SCE, and the MIC was 25 mg/mL for L. monocytogenes, S. typhimurium, and 75 mg/mL for H. pylori. In addition, amylase and protease enzyme activity was observed in both SCW and SCE.
