영문 초록

Perilla is an annual plant in the family Lamiaceae and are widely cultivated in Asian countries. Perilla leaves are important sources of bioactive compounds and are reported to exhibit anti-inflammatory, antibacterial, anti-cancer and antioxidant effects, drawing attention as functional food materials. We examined caffeic acid, rosmarinic acid, total phenol content, and antioxidant activity in the leaves of 18 perilla accessions obtained from the gene bank of the National Agrobiodiversity Center, Jeonju, Korea. The caffeic acid content ranged between 9.86-27.52 ㎎/g with an average content of 17.75 ㎎/g while the level of. rosmarinic acid was in the range between 49.14 and 90.30 ㎎/g with an average content of 61.88 ㎎/g. The total polyphenol content ranged between 138.39 ㎍ GAE/㎎ dried extract (DE) and 378.19 ㎍ GAE/㎎ DE with an average content of 225.93 ㎍ GAE/㎎ DE. Cluster analysis based on the content of caffeic acid, rosmarinic acid. and antioxidant activity showed that the accessions collections were grouped in two distinct classes. The first group contained six genetic resources with high content of rosmarinic acid, and antioxidant activities respectively. The second group contained 12 genetic resources with high content of caffeic acid. These results could help develop new varieties of nutrient dense perilla resources.
