본 연구의 목적은 인삼 종자의 70% 에탄올과 물 추출물에 대한 환원력, 라디칼과 아질산염 소거능 및 산화억제 효과 등의 항산화 활성을 비교하였다. 물 추출물의 고형분 함량은 3,350 mg/10 g으로 에탄올 추출물의 고형분 함량(2,930 mg/10 g)보다 높게 나타나 추출 수율은 에탄올 추출물(29.3%)보다 물 추출물 (33.5%)이 더 높았다. 추출물 농도에 비례하여 갈색도와 ...
본 연구의 목적은 인삼 종자의 70% 에탄올과 물 추출물에 대한 환원력, 라디칼과 아질산염 소거능 및 산화억제 효과 등의 항산화 활성을 비교하였다. 물 추출물의 고형분 함량은 3,350 mg/10 g으로 에탄올 추출물의 고형분 함량(2,930 mg/10 g)보다 높게 나타나 추출 수율은 에탄올 추출물(29.3%)보다 물 추출물 (33.5%)이 더 높았다. 추출물 농도에 비례하여 갈색도와 방향족 화합물의 함량도 증가하였다. 에탄올 추출물에 함유된 총 페놀 화합물(300.46 mg/100 g) 함량은 물 추출물(352.31 mg/100g)보다 다소 낮게 나타났으나, 총 플라보노이드 함량은 에탄올 추출물(177.7 mg/100 g)이 물 추출물(140.99 mg/100 g)보다 높게 나타났다. 두 추출물 모두 환원력은 높게 나타났는데 특히 ascorbic acid와 butylated hydroxytoluene보다도 유의하게 높은 것으로 확인되었다. 에탄올 추출물과 물 추출물의 1,1-diphenyl-2-picrylhydrazyl(DPPH) 라디칼 소거능은 각각 24.9%와 58.9%로 나타났다. 게다가 물 추출물의 지질 산화 억제 효과는 ascorbic acid보다도 높았고, 물 추출물의 항산화 지수는 에탄올 추출물 보다 약 3배 이상 높게 나타났다. pH 1.2에서는 에탄올 추출물(83.3%)의 아질산염 소거능이 물 추출물(24.3%)보다 월등히 높았으나, pH 3.0-6.0하에서는 두 추출물 사이에 유의한 차이가 없었다.

The purpose of this study was to determine the antioxidant activities such as reducing power, radical and nitrite scavenging capabilities, and lipid oxidation inhibition of the water and 70% ethanol extracts of ginseng seed, comparatively. The soluble solids content of ginseng seed was higher in the water extract (3,350 mg/100 g) than those in the ethanol extract (2,930 mg/100 g), therefore, the extraction yield of this seed obtained by water was 33.5%, which is much higher than that obtained by ethanol. The brown color intensity and aromatic compounds content of ginseng seed was directly in proportion to the concentration of the water and ethanol extracts. The total phenolic compounds content of the ethanol extract (300.46 mg/100 g) was slightly less than that of the water extract (352.31 mg/100 g), whereas total flavonoid content of the ethanol extract (177.7 mg/100 g) was higher than that of the water extract (140.99 mg/100 g). The ethanol and water extracts showed high reducing power, in particular, its value of the two extracts were significantly higher that of ascorbic acid and butylated hydroxytoluene. 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activities of the ethanol and water extracts were 24.9 and 58.9%,respectively. Additionally, the lipid oxidation inhibition of the water extract was more effective than that of ascorbic acid, and the antioxidant index of the water extract was almost three times higher than that of the ethanol extract. The ethanol extract (83.3%) showed better nitrite scavenging effect than the water extract (24.3%) at the strongly acidic pH (pH 1.2) condition, but there was no significant difference between two extracts at mildly acidic and neutral pH (pH 3.0-6.0).
