Abstract

The aim of our study was to investigate the chemical composition of the Asian ginseng seed (Panax ginseng C.A. Meyer) and the American ginseng seed (Panax quinquifolium L.) grown in Korea (3 years, KGS3; 4 years, KGS4), China (4 years, CGS4), and USA (4 years, AGS4). AGS had the heaviest 100-seed weight ($4.21{\pm}0.31g$). The approximate compositions of the ginseng seeds were 13.66-17.00% crude protein, 2.21-8.65% crude ash, 19.06-24.06% crude lipid, and 43.21-47.49% crude fiber. The mineral contents of the ginseng seeds were greater in order of K>P>Ca>Mg>Fe>Na>Zn >Cu. The unsaturated fatty acid content was 96.71-96.94%, and the major fatty acids oleic acid and linoleic acid were present. Total sugar content was 15.00-26.17 mg glucose/g. The acidic polysaccharide content was 0.56-0.80 mg ${\beta}$-Dgalacturonic acid/g. These results showed the differences in the physicochemical characteristics of ginseng seeds with respect to cultivation location, cultivation year, and species.

본 실험에서는 인삼 씨의 식품 유용자원으로서의 가능성을 알아보기 위해, 각국 인삼 씨의 무게, 일반성분, 무기질, 지방산 조성, 총 당, 산성다당체 함량을 비교해보았다. 먼저 인삼 씨의 백립중은 AGS가 $4.21{\pm}0.31g$으로 가장 무거웠다. 일반성분의 경우 조단백질 함량은 AGS가 $17.00{\pm}1.04%$로 가장 높았고, 조회분 함량은 KGS3가 $8.65{\pm}0.31%$로 매우 높은 값을 나타내 무기질이 풍부한 식품임을 확인할 수 있었다. 이는 저연근의 인삼일수록 무기성분이 많았던 연구결과와 일치했다. 조지방 함량은 AGS가 $24.06{\pm}0.57%$로 가장 높은 값을 나타냈고 조섬유소 함량은 43.21-47.49%로 전체 씨의 절반 정도가 섬유소로 이루어진 섬유질이 매우 풍부한 식품 자원임을 확인할 수 있었다. 무기질은 칼륨과 인이 가장 많이 함유된 것으로 나타났다. 지방산 조성은 96% 이상이 불포화 지방산으로, oleic acid (C18:1, n9c)가 79.93-87.09%로 가장 높게 나타났고, linoleic acid (C18:2, n6c)가 8.94-15.82%로 다음으로 많은 함량을 보였다. 품종이 다른 AGS는 유의적으로 oleic acid와 linoleic acid 조성에 차이가 났고, linolenic acid가 전혀 검출되지 않아 품종에 따른 지방산 조성의 차이를 확인할 수 있었다. 총 당 함량은 15.00-26.17 mg glucose/g으로 인삼에 비해서는 적었지만, 다른 씨와 비교했을 때 매우 높은 수치로 비교적 당을 많이 함유하고 있는 씨라는 것을 확인할 수 있었다. 인삼 산성다당체는 0.56-0.80 mg ${\beta}$-D-galacturonic acid/g을 함유해 소량이지만 최근 유효성분으로 알려진 인삼 산성다당체를 함유하고 있음을 확인하였다.
