Abstract
The objective of this study was to determine the biological activities of Sorglum bicolor extracts. Organic fractions, including n-Hexane, EtOAc, and n-BuOH fractions were obtained from the methanol extract of Sorglum bicolor M.. In DPPH radical scavenging activity, $SC_{50}$ values of methanol extract and EtOAc fraction were exhibited $0.66{\pm}0.26{\mu}g/mL$ and $1.03{\pm}0.02{\mu}g/mL$, respectively. Contents of total polyphenol and flavonoids in EtOAc fraction, which were much higher than those of other fractions, were 58.12 mg/g and 4.79 mg/g respectively. Also, effects of reducing power was strongly showed in EtOAc fraction. ${\alpha}$-Glucosidase and ${\alpha}$-amlyase inhibition activities were showed the higher effect in D.W. fraction ($2.83{\mu}g/mL$, $36.64{\mu}g/mL$). In MTT assay in the AGS, HT29 and HCT116 cell lines were significantly higher in the n-BuOH fraction than in the other fractions at $50{\mu}g/mL$ concentration of extracts.
