  • The physicochemical properties and schizandrin contents of various solvent ($H_2O$, 50% EtOH, 75% EtOH, 95% EtOH) extracts from residue after Omija juice was investigated using total polyphenol contents (TOC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity (RAS), anthocyanin contents (ANC), and schizandrin contents level (SCL). Total polyphenol contents, radical scavenging activity, and anthocyanin contents of 50% EtOH extract were the highest among all residue after Omija juice extracts, and was 16.70 mg/mL in the TOC and 86.16% in the DPPH-RAS. This meant that 50% EtOH extract from residue after Omija juice had more available antioxidant matters. As extraction time increases all extract treatments significantly reduced in the ANC contents (p <0.05). Amount of the SCL were observed higher value in 95% EtOH extract of residue after Omija juice.
