초록

Studies have been conducted on fermentation products known to increase biological activity through bioconversion of mycelium. In this study, ethanol extract of waxy sorghum (WS) and ethanol extract of waxy sorghum fermented with Phellinus linteus mycelium (WSPM) were prepared, and functional component contents, antioxidant activity, and cytotoxicity were analyzed. Total polyphenol contents and total flavonoid contents of WSPM were higher than those of WS. In addition, the β-glucan content of WS was higher than that of WSPM. DPPH and ABTS radical scavenging activities showed that WSPM had higher antioxidant activity than WS at all concentrations. Analysis of SOD-like activity also showed higher antioxidant activity in WSPM. MTT assay demonstrated that WSPM exhibited high inhibitory activity in all cancer cells, and in particular, in HeLa cells with the highest inhibition. A concentration-dependent increase in anticancer activities of WS and WSPM was detected in all cancer cells, which was identical to the SRB assay result. MTT and SRB assay showed the increased cytotoxicity of WSPM in cancer cells. Therefore, it is expected that WSPM can be used as a functional food material.
