Comparison of biochemical composition and antimicrobial activity of southern-type garlic grown in the eastern and western regions of Jeju

Abstract

Components and physiological activity of crops are strongly affected by the natural environments of the growth regions. In this study, we carried out soil analysis and determined the allicin, alliin, total pyruvate, total phenol and flavonoid, and reducing sugar contents of garlic from garlic-cultivating regions in the eastern and western portions of Jeju Province. Significantly higher contents of macronutrients were found in the soil and garlic from the eastern region of Jeju compared to western region, but micronutrients were higher in the western region than eastern region. In addition, the alliin and total phenolic contents were higher in the western region than in the eastern region. Also, allicin, total pyruvate, total flavonoid content, and ɑ-glucosidase inhibitory activity of the eastern region samples were higher than those of the western region in Jeju. This study promotes our understanding of the different components of garlic according to the cultivation regions of Jeju.
