Comparison of the major compounds and antimicrobial activities of Koara garlic cultivated in different regions

摘要

Although the chemical compositions and biological characteristics of some species of garlic have been investigated, data on Koara garlic are currently lacking. In order to investigate the major compounds and antimicrobial activity of Koara garlic, which was registered as a cultivar in 2012, it was cultivated in Seogwipo, Damyang, and Namhae. Analysis of the chemical composition of the cultivated garlic showed that the alliin, pyruvate contents, and antimicrobial activity were high in garlic grown inSeogwipo (9.44±0.28 mg/g, 127.52±5.50 pMJ%, and 0.31-1.25%, respectively). The total phenol content and reducing sugar contents were abundant in garlic grown in Namhae (82.23±0.00 g GAE/100 g and 28.59±0.54mg GE/g, respectively), and the total flavonoid content was high in garlic grown in Damyang (22.41±0.77g QE/l00g). Although garlics grown in different cultivation areas had different chemical compositions, major compound contents and biological activities of Koara garlic were similar to those ofother garlic varieties reported so far. These data will be useful for local farmers, distributors, and consumers.
