공기주입형 생물반응기를 이용하여 오미자 현탁배양세포로부터 Gomisin J의 생산 가능성을 확인 하였다. 시료의 초기접종 농도와 탄소원의 농도에 따른 세포증식과 Gomisin J의 생산성은 6% sucrose가 첨가된 MB5배지 에 100 g (FCW)의 현탁배양세포를 접종하였을 경우 세포중량 (dry biomass)과 Gomisin J의 함량은 각각 43.5 g DCW/과 $0.71\;{\times}\;10^{-3}\;{\mu}g/g$ DCW을 얻을 수 있었다. 배양기내 산소의 공급량은 0.5로 공급해 주는게 바람직 할 것으로 사료되었다.

Cell growth and gomisin J production by suspension cultures of Schisandra chinensis Baillon were investigated under various culture media, initial sucrose concentrations, shaking speeds, and inoculum sizes. Callus was induced from in vitro cultivated leaf segments on MS medium supplemented with $1\;mg/{\ell}$ NAA. The maximum dry cell weight of 2.23 g was obtained at inoculum size of 0.5 g fresh cell weight and in MB5 medium supplemented with $1\;mg/{\ell}$ NAA, 3% sucrose after 8 weeks. The production of gomisin J in suspension cell cultures was maximized in WPM medium containing 5% sucrose. The shaking speed for maintaining maximal cell dry weight was 100 rpm while the best shaking speed for gomisin J accumulation was 140 rpm.

Transformed roots of Schisandra chinensis were obtained following co-cultivation of in vitro cultivated plantlet segments with Agrobaterium rhizogens ATCC15834. This root was examined for its growth and gomisin J contents under various culture conditions. Among the six basal culture media tested, WPM (Lloyd & McCown, 1980) medium supplemented with 5% sucrose was the best roots growth 6.2 (g D.W/flask) and gomisin J accumulation 1.56 $(X10^{-3}\;ug/g\;D.W)$. Initial inoculum size correlated with the yield of biomass while gomisin J contents was not affect. Gomisin J production was influenced by the initial sucrose concentration and the highest production yield was achieved at the concentration of 7%. The optimal shaking speeds for roots growth and gomisin J production was 120 and 140 rpm, respectively.

Four lignan compounds including gomisin J (1), schizandrin (2), gomisin A (3), and angeloyl gomisin H (4) have been isolated from the MeOH extract of Schizandra chinensis fruits. The evaluation for protective effect of compounds 1-4 against tert-butyl hydroperoxide (t-BHP)-induced cytotoxicity in hippocampal HT22 cell line was conducted. Compound 1 showed significant protective effect with an $EC_{50}$ value of $43.3{\pm}2.3\;{\mu}M$, whereas compounds 2-4 were inactive. Trolox, one of the well-known antioxidant, used as a positive control, and also showed protective effect with an $EC_{50}$ value of $213.8{\pm}8.4\;{\mu}M$. These results suggest that compound 1 may possess the neuroprotective activity against oxidant-induced cellular injuries.

Five lignans including gomisin N (1), wuweizisu C (2), gomisin L1 (3), (+)-deoxyschizandrin (4), and gomisin J (5) have been isolated from the fruits of Schizandra chinensis. The structures of the isolated compounds were elucidated by analyzing MS and NMR spectra. Effects of the compounds isolated in this study on the dopamine content in PC12 cells were investigated to evaluate their inhibitory effectiveness. The gomisin N, wuweizisu C, and gomisin J showed 25.4%, 39.8%, and 35.1 %, respectively, inhibition effect on dopamine content in PC12 cells at the concentration of $50\;{\mu}g/ml$.

GC/MS를 이용하여 오미자의 chloroform-methanol 추출물로부터 11종의 lignan 성분을 동정하였다. GC column은 SPB-1 fused silica capillary $(0.25mm\;ID{\times}30m,\;Supelco)$를 사용하였고 column oven의 온도는 $200^{\circ}C$부터 $300^{\circ}C$까지 분당 $4^{\circ}C$씩 승온하였으며 MS의 ionization voltage는 70eV (El mode)이었다. 동정된 lignan 성분은 gomisin J, deoxyschizandrin, gomisin N, schizandrin, wuweizisu C, gomisin A, angeloylgomisin H, tigloylgomisin H, angeloylgomisin Q, gomisin B 및 benzoylgomisin H이었으며, GC chromatogram 상에서 이들 화합물의 분리상태는 양호하였다.

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.

In the course of search for hepatoprotective agents from oriental traditional medicines, one compound was isolated from the MeOH extract of the fruits of Schizandra chinensis, and its structure was determined as gomisin J(1). The evaluation for hepatoprotective activity of isolated compound 1 on drug-induced cytotoxicity was conducted, and compound 1 showed protective effect with an EC$_{50}$value of 86.0 ${\pm}$ 5.3 ${\mu}$M against tacrine-induced cytotoxicity in Hep G2 cells. One of the well-known hepatoprotective agents, silybin, used as a positive control, and the hepatoprotective effect of compound 1 is similar with that of silybin (EC$_{50}$ value = 90.5 ${\pm}$ 9.8 ${\mu}$M).
