This study was carried out to utilize the byproducts(flower, immature and mature fruit, leaf and stem) of ginseng. Yield of byproducts were 32.7±9.8g in flower, 68.2±2.2g in mature fruit, 48.5±4.3g in mature fruit, 316.2±20.5g in leaf, and 296.6±15.4g in stem per 3.3㎡(180×90 cm, ginseng root 675.5±35.7g/drybasis). The total saponin contents of ginseng byproducts and rootare 52.36±1.24, 68.71±1.98, 168.89±0.57, 68.26±1.32, 7.85±0.61 and 35.08±0.96mg/g, respectively. The main ginsenoside of all byproducts was Re and the highest content was 132.23±1.56 mg/g in mature fruit. But flower and fruit wasnot detected Rf and Rh1, respectively. Total polyphenolic compound content on mature fruit was the highest, 2.242±0.140%, after, immature fruit>leaf>flower>root>stem order. The DPPH radical scavenging activity on mature fruit wasthe highest,0.115±0.004 mg/mL(IC50),and the others were the same order of polyphenolic compound and ginsenoside content on byproducts.
