Objectives : We investigated differances of physiological functionalities in the steamed Schisandrae Fructus. Methods : The samples were extracts of dryed schisandrae fructus without steaming process (S0), extracts of schisandrae fructus with three times steamed (S3), extracts of schisandrae fructus with five times steamed (S5) and extracts of schisandrae fructus with seven times steamed (S7). We analyzed contents of schisandrin, gomisin, total polyphenol and flavonoid and antioxidant activities. We researched antiinflammation effects for Raw264.7 cells. To evaluate liver protective activity, we measured AST, ALT and gamma-GTP in serum of alcoholic mice. Results : As the steaming number of schisandrae fructus increase, the contents of schisandrin and gomisin were more increased. The contents of total polyphenol of S5 and S7 were significantly increased compared to that of S0. DPPH free radical scavenging activities of S5 and S7 were significantly increased compared to that of S0, ABST radical scavenging activities of S3 and S5 were significantly increased compared to that of S0 in vitro. The NO production of all sample was significantly decreased compared to control, PGE2 release of S3, S5 and S7 were significantly decreased compared to control. IL-$1{\beta}$ release of S5 and S7 were significantly decreased. AST, ALT and gamma-GTP of S3, S5 and S7 were significantly decreased compared to control. Conclusions : We think that extracts of schisandrae fructus with steaming process may have more potential efficacy than a schisandrae fructus without steaming process.

Schisandra chinensis Baill. (Shisandraceae) is used commonly in traditional Korean herbal medicine. One new dibenzocyclooctene lignan compound, benzoylgomisin Q, was found, for the first time, in the fruits of Schisandra chinensis Baill., together with five known lignan compounds; schisandrin, gomisin A, gomisin G, deoxyschisandrin, and gomisin N, using an ESI-positive MS-preparative HPLC auto-purification system. The structures of these compounds were determined via UV, MS, and NMR spectral studies.

오미자 추출물의 n-hexane 분획으로부터 open column chromatography, 분취용 HPLC 등 여러 가지 크로마토그라피를 이용하여 총 15종의 화합물을 분리하였다. 분리된 화합물들은 각각의 기기분석 데이터를 문헌치와 비교하여, 각각 wuweizisu C (1), gomisin N (2), deoxyschisandrin (3), gomisin A (4), schisandrin (5), chamigrenal (6), schisanlactone D (7), methylgomisin O (8), angeloylgomisin O (9), (-)-gomisin $L_2$ (10), schisandronic acid (11), (-)-gomisin $L_1$ (12), (+)-gomisin $K_3$ (13), gomisin J (14), tigloylgomisin H (15)으로 동정하였다. 이들 중 methylgomisin O (8)는 이 식물에서 처음으로 분리되었다. 분리된 화합물들은 HL-60 (human leukemia), HeLa (human cervical carcinoma) 및 MCF-7 (breast cancer cells) 세포주에 대하여 세포독성 실험을 실시하였다. 그 결과 화합물 7, 8 및 9는 HL-60 세포주에 대하여 각각 7.37, 6.60 및 $8.00{\mu}M$의 $IC_{50}$로 비교적 강한 세포독성 효과를 나타냈다. 화합물 6은 MCF-7에 대하여 $IC_{50}$ $30.50{\mu}M$로 적정한 세포독성을 나타냈다. 그리고 화합물 8은 HeLa cells에 대하여 $IC_{50}$ $1.46{\mu}M$로 비교적 강한 세포 독성으로 나타냈다.

Schisandra chinensis is a fruit which is called Omija in South Korea. The Korean word Omija means "five flavors" (sweet, spicy, sour, bitter, and salty). The aim of his study was to investigate the correlation between growth characteristics and lignans (gomisin A, gomisin N, schisandrin) contents of Schisandra chinensis. The method for determining lignans was validated by measuring the linearity, limit of detection (LOD), limit of quantification (LOQ), precision and accuracy using UPLC-UV. Growth characteristics of S. chinensis such as number of fruits per fruit bunch, length of fruit bunch, width of fruit bunch, fresh weight of fruit bunch, length of fruit, width of fruit, fresh weight of fruit, fresh weight of 30 fruits, and sugar contents of fruit were measured. From the results of correlation analysis, it was found that the contents of lignans showed a significantly negative correlation with fresh weight and sugar contents of fruit. These results will be used to study for quality control of S. chinensis fruit.

There are about 2 genera and 49 species of Schisandraceae all over the world which grow 2 genera and 5 species in korea. As'Schisandra'genus, S. chinensis, S. repanda, S. nigra and S. viridicarpa are distributed. As 'Kadsura' genus, there is K. japonica species. Although S. chinensis is often used for food and herbal medicine, 'Cheongsoon'is the only cultivar in korea. Therefore cultivar breeding is required for standardized production of Schisandra chinensis. To select superior lines, characteristics of collected varieties was investigated. These collections were from all the country including Mungyeong, Muju and Jangsu. In the case of 'Schisandra chinensis', analysis of chemical compound is very important. Because in 'Korean Pharmacopoeia', Schisandrin has to contain more than 0.7% of sum of Shizandrin, Gomisin A, Gomisin N as standard compound. According to the investigation, the weight of SC-154 was the highest one that was 99g of fresh fruit and 60g of dried fruit in the 100 granulas of it. As the control group, the weight of cultivar 'Cheongsoon'was 57g of fresh fruit and 40g of dried fruit. The chemical compounds such as Shizandrin A, Gomisin A, Gomisin N and Shizandrin C from the collections were analyzed by HPLC. As a result, all average of total content was 1.67% satisfied with the standard that is over 0.7%. Among them, SC-13, SC-22, SC-40 and SC-45 had more than 2.0% of compound. In this case, the content of Gomisin N was relatively higher than that of the other collections. It can be used for high content compound breeding. This above results indicate that these findings could be used for breeding superior Schisandra chinensis through selection of high quality resource.

본 연구에서는 오미자 열매로부터 모유두세포 증식에 활성을 나타내는 gomisin N을 정제하고 gomisin N의 함량이 높은 추출물을 얻기 위한 최적의 추출조건을 확인하였다. 추출물 및 분획물에 대하여 모유두세포 증식 활성 실험을 진행한 결과, n-hexane 분획물 1 ㎍/mL 처리군에서 약 29%의 증식 활성을 나타내었다. n-Hexane 분획물의 활성성분을 규명하기 위하여 column chromatography를 진행하였으며 2 개의 화합물 gomisin N (1)과 schizandrin (2)를 분리 동정하였다. 분리된 화합물에 대한 모유두세포 증식 활성 실험 결과, gomisin N에서 최대 20%이상의 증식 활성을 나타내었다. 따라서 오미자 열매로부터 최대치의 gomisin N을 얻을 수 있는 최적추출조건을 반응표면분석(RSM)을 사용하여 확인하였다. 최적추출조건을 설정하기 위해 에탄올의 비율, 추출시간, 추출온도를 독립변수로 하여 실험한 결과, 0.95 이상의 결정계수와 0.05 이하의 p-value를 나타내어 모델의 적합성이 확인 되었다. Gomisin N의 최대함량을 위한 최적추출조건은 에탄올 비율 83.8%, 추출온도 80 ℃, 추출시간 8.7 h으로 확인되었고, 최적추출조건에서 gomisin N의 함량은 378,300 ppm으로 예측되었다. 최적추출조건에 대한 실제 검증에서 평균 376,884 ppm으로 예측된 값과 유사한 결과를 확인 할 수 있었다
