Abstract

|
|
|
This study was undertaken to evaluate the physiological activities for subsequent utilization of Deodeok (Codonopsis lanceolata Trautv.) buds as a new functional food. Deodeok buds (CLS-A∼D) were classified according to the growth length. The total polyphenol and flavonoid contents of the 70% ethanol extracts ranged from 580.82 to 719.56 mg GAE/100 g, and 287.45 to 398.52 mg CE/100 g, respectively. The contents tended to decrease with increasing growth length of Deodeok buds. The DPPH and ABTS radical scavenging activity of CLS-B were determined to be 622.87 and 436.98 mg AA eq/100 g, respectively, showing the highest antioxidant activity. Similar to other contents, increasing growth length resulted in decreased antioxidant activity. Moreover, tyrosinase, α-glucosidase, and elastase enzyme inhibitory activities of Deodeok buds also showed best inhibitory effect in CLS-B. Considering the result of this study, we confirm the possibility of wide application of Deodeok buds as a new functional food material.
