Steamed ginseng is well known as a tonic medicine for restoring and enhancing human health. Steamed ginseng had more pharmacologically activity than white ginseng. The effects of steamed ginseng on transplantable tumors, proliferation of lymphocyte and rat liver lipid peroxidation were studied. This study was performed to evaluate the antioxidation and antiwrinkle effects of three ginseng extracts. Raw ginseng (RGS) and dried ginseng (DGS) mature like red ginseng in addition to the ready-made red ginseng (GS) purchased in the market, were steamed and extracted by red ginseng extractor. Three extracts of steamed ginseng were investigated to determine effects of superoxide radical scavenging activity, hydroxyl radical scavenging activity, autooxidation inhibition of linoleic acid, collagenase inhibition and collagen synthesis in normal fibroblast. RGS showed not only the highest superoxide radical scavenging activity at a concentration of 100 ug/mL but also the hydroxyl radical scavenging activity higher than vitamin C. Also RGS showed the highest activity in inhibition of autooxidation of linolic acid, collagen synthesis, and collagenase inhibition.

The use of the microwave-assisted process for the extraction of effective constituents from ginseng was investigated at various operating conditions. The influence of solvent (ethanol-water, 50% v/v) to ginseng ratio, particle size and applied microwave power on the efficiency of extraction was examined. The microwave extraction system used was custom manufactured so that the intensity of microwave may be varied by using anode-voltage controller. It was found that the ratio of 6 : 1 (vol/mass) gave a good extraction efficiency. Small particle size gave high yield but it caused difficulties in the separation of solvent from the sludge. The higher power was no guarantee of the efficient extraction yield. The more important factor than the employed power was the adequate temperature under sufficient contact time. Using deionized-water as swelling agent, the degree of swelling of ginseng by microwave heating and conventional heating in water-bath was also studied. It was observed that the microwave heating enhanced the swelling much more than the conventional heating. It is believed that this enhanced swelling was responsible for the rapid microwave-assisted extraction rate.

This study was made to observe changes in hemograms of the Sarcoma-180 mouse treated with extracts of Poria cocos and Panax ginseng. The life span of the Sarcoma-180 mouse administered with the mixture of the extract of Panax ginseng with the extract of P. cocos and the extract of P. cocos was extended more than the non-treated group. In the body weight of the Sarcoma-180 mouse, the non-treated group was increased more than the normal group and the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract. In the numbers of white blood cell especially lymphocyte, the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract were similar to the normal group, but the non-treated group was decreased. The Hematocrit, mean corpuscular volume and mean corpuscular hemoglobin in the mice infected with Sarcoma-180 were not significantly different between the group treated with extracts of them and the non-treated group. In the distributions and sizes of white blood cell and platelet in the mice, the group administered with the Hoelen extract was similar to the normal group comparing to the non-treated group.

Purpose: Aster glehnii (AG) and Aster yomena (AY) are medicinal plants that belong to the family Compositea and grow widely in Korea. Plants in the genus Aster have been used to treat snakebite wounds or bruises in oriental medicine. This study compared the effects of anti-oxidants and anti-adipocyte differentiation according to the species (the aerial parts of AG and AY). Methods: AG and AY were extracted using 70% ethanol (-E) and water (-W) at room temperature. The anti-oxidant activities were measured by total phenol contents (TPC), total flavonoid contents (TFC), DPPH and $ABTS^+$ assay. In addition, correlation analysis was performed for the anti-oxidant compounds and effect. The level of anti-adipocyte differentiation was assessed using an oil red O assay on pre-adipocytes. Results: AG-W showed higher TPC ($6.92{\mu}g/mL$) and AG-E presented higher TFC ($8.22{\mu}g/mL$) than the other extracts. Furthermore, AG-E exhibited higher radical scavenging activity in the DPPH and $ABTS^+$ assay ($IC_{50}$: 104.88 and $30.06{\mu}g/mL$). In the cytotoxicity assay, AG and AY extracts at concentrations less than $100{\mu}g/mL$ were non toxic. AG-W reduced the lipid accumulation of 3T3-L1 cells significantly after differentiation (70.49%) compared to the other extracts. Conclusion: These results show that the water extract of AG has anti-oxidant effects and reduces the differentiation of 3T3-L1 cells. Therefore, AG has utility as a functional food material for its anti-oxidant activities and ability to prevent lipid accumulation.

Antioxidative capacities of Stachys sieboldii MIQ and 6-year-old ginseng powder were assessed after extraction with 80% ethanol, and their addition effects on quality characteristics of cookies were determined. Stachys sieboldii MIQ showed 3.12-fold higher total phenol content (TPC) and higher antioxidative capacities than ginseng based on higher values of 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity, ferric reducing antioxidant capacity, and Trolox equivalent antioxidant capacity (P<0.05). The 80% ethanol extract was then fractionated with $H_2O$ (Fr. I), 30% (II), 50% (III), 70% (IV), and 100% ethanol (V). Fractions of Stachys sieboldii MIQ extract showed 2.2-fold (Fr. I)~6.1-fold (III) higher TPC and higher antioxidative capacities than ginseng extract fractions. TPC was in the order of fractions III> II> I> IV> V for Stachys sieboldii MIQ extract while in the order of fractions I~III> IV~V for ginseng extract, assuming that Stachys sieboldii MIQ contained more phenolic compounds with higher polarity than ginseng. Addition of 5% and 10% Stachys sieboldii MIQ and ginseng powder increased spread ratio in cookies compared to 100% wheat flour, and 10% addition of Stachys sieboldii MIQ resulted in the darkest and most reddish cookies. In the sensory evaluation, cookies with 5% and 10% Stachys sieboldii MIQ received higher scores for taste preference and higher overall acceptability than ginseng or control cookies. Therefore, powder of Stachys sieboldii MIQ could impart more favorable sensory characteristics as well as higher antioxidative capacity than ginseng in bakery products.

최근에 고령화 사회에 접어들면서 건강하게 활동하며 수명을 다하는 것이 중요한 연구과제가 되고 있다. 이 때문에 영양, 운동, 스트레스, 환경 등과 관련하여 암, 당뇨병, 고혈압, 비만, 동맥경화 등 생활습관병의 극복이 사회문제가 되고 있는 실정이다. 지금까지 고려인삼의 대표적인 동물실험 및 임상학적 연구결과를 종합하여 보면 성인의 난치성 만성질환에 대해서 치료제보다는 질병을 예방하고 회복촉진에 보다 큰 효과 있음을 확인할 수 있다. 이는 인삼이 식품과 의약품의 중간에 위치한 식품의약품(Nutraceutical)의 용도로 활용할 수 있음을 시사한다. 현재까지 인삼제품에 표시되는 기능성의 내용은 약 3,000여편 이상의 약리효능에 관련된 논문이 발표되었다 하더라도 "피로회복, 면역력 증진, 혈소판 응집 억제를 통한 혈액흐름에 도움이 됩니다"이며 이외의 기능성 표시는 현재로서 원칙적으로 불가한 것으로 되어 있다. 그러나 시험물질의 규격화 및 임상시험의 검토기준을 만족시키는 과학적 자료제출에 의한 개별 평가 후 표시내용의 확대가 가능하다. 고려인삼의 다양한 성분 중 ginsenoside는 주요 약효성분으로 인정을 받고 있으며 현재 품질관리의 지표성분으로 활용되고 있다. 이러한 개별 ginsenoside의 약리작용을 보면 서로 유사 또는 상반된 효과를 보여주는 성분들이 공존하고 있어 인삼의 다양한 약리효과와 일맥상통하는 것으로 보고되고 있다. 아울러, ginsenoside는 인삼의 부위 별로 현격한 차이를 보여주기 때문에 소재의 규격화는 매우 중요하다고 판단된다. 따라서, 인삼제품 개발의 가장 중요한 조건은 의약품에 가까운 기능성식품으로 세계적인 제품을 만들기 위해서는 표준화가 선행되어야 한다. 이와 같은 조건을 잘 충족시키는 제품이 스위스 "파마톤의 진사나(백삼추출물, G115)" 제품으로 생각할 수 있다. 따라서, 고려인삼의 수출시장 확대 및 세계적인 제품을 위해서는 진사나에 필적할 수 있는 새로운 홍삼의 표준화된 추출물을 도출하는 것이 무엇보다 급선무라 생각한다. 아울러 고려인삼의 특장점 발굴을 위한 표준화 된 추출분획물, 활성성분 및 효능과 연계한 새로운 고부가가치 창출제품(식품/의약품)개발에 주력해야 할 것이다.

This study was conducted to examine the antioxidant activities and physiological activities of mixture extracts (Liriope platyphylla, Schizandra chinensis and Panax ginseng C.A. Meyer) with different extraction mixing ratios (MEC, 2:1:1; ME1, 1:2:1; ME2, 1:1:2; ME3, 1.34:1.33:1.33). The yield of extracts ranged from 25.33 to 33.87%. The total polyphenol and total flavonoid contents of ME1 extracts were 1.01 g/100 g, 0.07 g/100 g, respectively. The total sugar contents of MEC extract was 22.83 g/100 g, respectively. The DPPH and ABTS radical scavenging activities of ME1 extracts at $1,000{\mu}g/mL$ were 26.79% and 21.08%. The superoxide radical scavenging and ferric-reducing antioxidant power of ME1 extracts at $1,000{\mu}g/mL$ were 67.83% and $295.47{\mu}M$, respectively. The functionalities of extracts were investigated with L-132 and RAW264.7 cell lines. The extracts on different mixing ratios did not show the toxicity on L-132 and RAW264.7 cell line in $100-2,500{\mu}g/mL$. The ME1 extract of $1,000{\mu}g/mL$ performed better than other extracts protective effects against oxidative stess in L-132 cells (81.22%) and the ME2 extract at $1,000{\mu}g/mL$ decreased nitric oxide production by $7.48{\mu}M$ which was more potent than other extracts. There results suggest that the ME1 extracts may be a useful functional food material in the food industry.
