Abstract
|
|
|
|
This study was conducted to investigate the applicability of the ground parts such as flower (GF), berry (GR), and leaf (GL) from Panax ginseng C. A. Meyer. The ground parts were extracted from hot water (WE) and 60% ethanol (EE). Total polyphenol and flavonoid contents were 15.02-32.74 and 21.60-484.05 mg GAE/g, respectively. Hot water extract of ginseng leaf (GLWE) and 60% ethanol extract of ginseng leaf (GLEE) showed higher total polyphenol and total flavonoid contents than other extracts. Crude saponin contents were found in the range of 15.30-37.27%. Antioxidant activity of these extracts from ginseng was also analyzed by DPPH, ABTS, H2O2 scavenging activity, reducing power, and inhibition effect on lipid peroxidation. We confirmed the results that hot water extract of ginseng leaf (GLWE), 60% ethanol extract of ginseng leaf (GLEE) has high anti-oxidative effects. According to the antioxidant activity results of each extract of ginseng flower, ginseng berry, and ginseng leaf, it is judged that their availability is very high, and if proper processing is performed, it can be used as a functional raw material.
