초록

Background : Sorghum (Sorghum bicolor) is the fifth most important crop in the world. Although it is known as a crop with many medicinal action, Studies on sorghum breeding are inferior to other crop. Therefore, it is necessary to cultivate excellent varieties of sorghum which is stable and has excellent physiological activity. So, this study was conducted to investigate the total phenolic content and the total flavonoid content of the sorghum accessions to select the sorghum accessions with rich antioxidants. The results of this study can be used as basic data for future breeding.
Methods and Results : The seeds for study were supplied from the Center for Agricultural Genetic Resources of National Institute of Agricultural Sciences. The seeds were extracted with 100% methanol and concentrated at 45℃. To determine antioxidant, we measured the total phenolic content and total flavonoid content. The highest total phenolic content showed in the accession from IT No. 155552 (55600.34 ± 17.78 ㎎·GAE/g) and the total flavonoid content showed the highest in IT No. 143716 (116563.20 ± 149.39 ㎎·QE/g). On the other hand the lowest total phenolic content showed in the accession from IT No. 135777 (20.14 ± 4.29 ㎎·GAE/g) and the total flavonoid content showed the lowest in IT No. 152910 (701.25 ± 5.53 ㎎·QE/g).
Conclusion : Among 300 sorghum accessions, we analysed the total phenolic contents and total flavonoid contents.
