Yield and Quality Characteristics of Ginseng's First Byproducts

Abstract

This study was carried out to utilize the byproducts (flower, immature and mature berry, leaf and stem) of ginseng. Yield of byproducts were 32.7 ± 9.8 g in flower, 68.2 ± 2.2 g in immature berry, 48.5 ± 4.3 g in mature berry, 316.2 ± 20.5 g in leaf, and 296.6 ± 15.4 g in stem per 3.3㎡ (180 × 90 ㎝, ginseng root 675.5 ± 35.7 g/drybasis). The total saponin contents of ginseng byproducts and root are 52.36 ± 1.24, 68.71 ± 1.98, 168.89 ± 0.57, 68.26 ± 1.32, 7.85 ± 0.61 and 35.08 ± 0.96 ㎎/g, respectively. The main ginsenoside of all byproducts was Re and the highest content was 132.23 ± 1.56 ㎎/ g in mature berry. But flower and berry was not detected Rf and Rh1, respectively. Total polyphenolic compound content on mature berry was the highest, 2.242 ± 0.140%, after, immature berry > leaf > flower > root > stem order. The DPPH radical scavenging activity on mature berry was the highest, 0.115 ± 0.004 ㎎/mL(IC50), and the others were the same order of polyphenolic compound and ginsenoside content on byproducts.
