초록

Deodeok is a crop widely distributed in Asia; its fresh or dried roots are used as medicine. It exhibits excellent antioxidant and antibacterial effects owing to the abundance of its functional components. Deodeok can be distinguished from ginseng using the marker compounds tangshenoside I and lobetyolin, abundant in deodeok; however, further research on this crop and its utilization is needed. In this study, we aim to measure the functional ingredients and physiological activities using the flesh and skin of Korean and Chinese deodeok samples and to use these basic data for the development of functional foods. A higher Tangshenoside I content was detected in the skin than in the flesh, with the highest concentration identified in Jeju Deodeok (302.07 μg/g) among Korean and Ji'an Deodeok (662.97 μg/g) among Chinese samples. Similarly, the skin exhibited higher lobetyolin content and five types of phenolic compounds than the flesh.
The physiological assay revealed that the antioxidant activity increased with increasing total polyphenol content; a high antioxidant activity was detected in the skin. The skin of deodeok, collected in the sprout stage, can be effectively used. Additionally, during hydroponic cultivation of deodeok sprouts, an increase in the secondary metabolite content can be induced using a regulated source of artificial light.
