산삼배양근을 식품소재 첨가물로의 이용성을 알아보고자 열수 및 70% 에탄올 추출물에 대한 항산화 활성을 측정하였다. 열수추출물의 수율은 건물당 27.86%이었으며, 70% 에탄올추출물은 18.33%이었다. 총 폴리페놀 함량은 열수 및 70% 에탄올 추출물에서 각각 17.90 mg/g 및 22.63 mg/g 이었다. Ginsenoside Rb1 및 Rg1의 함량은 각각 1.45 mg/g 및 0.96 mg/g 이었다. 1~20 mg/mL 농도에서 물추출물 및 70% 에탄올 추출물의 전자공여능은 각각 2.82~60.58% 및 3.88~70.88% 이었으며, 환원력에서는 70% 에탄올 추출물이 0.07~1.90이었고 물 추출물은 대체적으로 낮았다. SOD 유사활성은 물 추출물은 큰 차이가 없었으나 70%에탄올 추출물에서는 농도가 증가함에 따라 유의적으로 증가하였다. 아질산염 소거능은 SOD 유사활성의 결과와 유사하였다. 지질산패 억제능은 70% 에탄올 추출물은 9.18~66.59%로 물 추출물의 4.74~24.88%에 비하여 1.9~2.8 배 높은 활성을 나타내었다. 이상의 결과로 볼 때 산삼배양근 추출물은 70% 에탄올 추출물의 항산화성이 우수하여 산화방지제 및 기능성 증진용 소재 활용에 효과가 있을 것으로 판단된다.

We obtained hot-water extracts (HWE) and 70% (v/v) ethanol extracts (EE) from cultured wild ginseng roots (CWGR) and determined the saponin and total polyphenol contents, and antioxidant activities. The yields of freeze-dried powder from the HWE and EE were 27.86% and 18.33% (both w/w), respectively. The total polyphenol content of the EE (22.63 mg/g) was higher than that of the HWE (17.90 mg/g). Ginsenoside-Rb1 and -Rg1 contents of hot-air-dried CWGR were 17.90 mg/g and 22.63 mg/g, respectively. The electron-donating ability of HWE and EE were 2.82-60.58% and 3.88?70.88%, respectively, and the reducing powers ($OD_{700}$) were 0.02-0.17 and 0.07-1.90, respectively, at concentrations of 1-20 mg/mL. Thus, the HWE reducing power was markedly lower than that of the EE, but the SOD-like activity of the EE was significantly higher than that of the HWE. The nitrite-scavenging activities of HWE and EE were 9.25-19.18% and 11.94-53.49%, respectively, at concentrations of 1-20 mg/mL. Additionally, the TBARS (Thiobarbituric acid reactive substances, % value) of the EE (1-20 mg/mL) was 9.18-66.59%, thus 1.9-2.8-fold greater than that of the HWE (4.74-24.88%). In conclusion, we provide experimental evidence that extracts of CWGR may be natural antioxidants.
