The aim of this study was to develop a rapid and cheap bioassay of four lignans (schisandrin, schisandrin C, the gomisin A and gomisin N) isolated from Schizandra chinensis Baill on seed germination and seedling growth of the radish. Its structure was determined by analysis of MS and NMR spectroscopic data. Radish seeds immersed for 1 hr in the solutions of $10^{-5}M$, $10^{-6}M$ and $10^{-7}M$ of schisandrin, schisandrin C, gomisin A, and gomisin N, seed germination was observed with in 60 hr after all of the treatments. Also, the seeds were germinated faster compared to untreated controls. At early germination stage, 48 hr after the treatment of the lignans, the suppression of germination was observed from all treatments; the suppression due to schisandrin and gomisin A was the highest at the concentration of $10^{-6}M$. The level of suppression increased as the concentration increased in the treatment of schisandrin C and gomisin N. Percent germination of seed after 184 hr was increased 90% at all treatments. For the effects of lignan treatment on seedling growth in radish, the growth of hypocotyl was promoted by gomisin A and gomisin N at all concentrations. Root elongation was significantly promoted by schisandrin and gomisin N at $10^{-5}M$ and $10^{-6}M$, respectively. Fresh and dry weights of the seedlings were high at a low concentration of $10^{-7}M$, but significantly reduced by schisandrin C at a high concentration of $10^{-5}M$. The results of the germination activity and seedling growth of the lignans from S. chinensis suggest their potential use as natural growth regulators.

Deoxyschizandrin, gomisin N, schizandrin, wuweizisu C, gomisin A and angeloylgomisin H were isolated from fruits of Schisandra chinensis BAILLON, and the lignan contents in shred and smoke of 'Balloon-Flower' cigarettes were quantitatively analyzed by capillary-GC(FID). The GC column was SPB-1 fused silica capillay (0.25mm id$\times$30m, Supelco) and the column oven temperature was programmed from 20$0^{\circ}C$ to 30$0^{\circ}C$ at the rate of 4$^{\circ}C$/min. In the shred of 'Balloon-Flower' cigarettes deoxyschizandrin. gomisin N, schizandrin, gomisin A and angeloylgomisin H were detected and schizandrein contets were the highest among them, 22.77$\mu\textrm{g}$/cig., gomisin N, schizandrin and gomisin A were 0.023, 0.054, 0.0849 and 0.167$\mu\textrm{g}$/cig. respectively, and angeloylgomisin H was not detected.

In the present study, we have refined gomisin N, which represents activity in the proliferation of dermal papilla cells (HFDPCs) from the fruit of Schisandra chinensis (S. chinensis), and have identified optimal extraction conditions for obtaining extracts with high content of gomisin N. The activity of the extracts and fractions was evaluated, and the results indicated approximately 29% proliferation activity in the group treated with 1 ㎍/mL of n-hexane fraction. Column chromatography was used to assess the active ingredient in the n-hexane fraction, and two compounds, namely gomisin N(1) and schisandrin(2), were isolated and identified. When the HFDPCs proliferation activity was tested for the isolated compounds, gomisin N exhibited ≥ 20% proliferation activity. Thus, via response surface methodology (RSM), the optimum extraction conditions to obtain the maximum level of gomisin N from the fruit of S. chinensis were determined, where ethanol proportion, extraction time, and extraction temperature were used as the independent variables. The results revealed coefficient of determination ≥ 0.95 and p-value ≤ 0.05, which confirmed the fit of the model. The optimum extraction conditions to achieve the maximum content of gomisin N were as follows: ethanol proportion 83.8%, extraction temperature 80 ℃, and extraction time 8.7 h. The content of gomisin N using these conditions was predicted as 378,300 ppm, and a mean value close to the predicted value (376,884 ppm) was obtained while validating the aforementioned conditions.

The determinabilities of several lignan compounds by capillary-GC (F1D) were studied. The lignan compounds used were deoxyschizandrin, gomisin N, schizandrin, wuweizisu C, gomisin A, angeloylgomisin H and tigloylgomisin H which were isolated from fruits of Schisandra chinensis BAILLON and identified with GC/MS(EI, 70eV), 1H-NMR(300MHz) and IR. The GC column used was SPB-1 fused silica capillary$(0.25mm\;ID{\times}30m,\;Supelco)$, and the column oven temperature was programmed from $200^{\circ}C$ to $300^{\circ}C$ at the rate of $4^{\circ}C$ per minute. The linearities between concentration and FID response were maintained in $2{\sim}500ppm$ of deoxyschizandrin and wuweizisu C and in $5{\sim}500ppm$ of gomisin N, schizandrin, gomisin A, angeloylgomisin H and tigloylgomisin H. The contents of lignan compounds in fruits of S. chinensis BAILLON produced at Moo-ju area were analyzed by the GC method: the values obtained of schizandrin and gomisin N were 6.5 and 5.9mg/g respectively, and those of gomisin A, wuweizisu C, angeloylgomisin H, deoxyschizandrin and tigloylgomisin H were $0.5{\sim}1.6mg/g$.

Two lignanes, Comp.-I, mp 108-1$0^{\circ}C$ and Comp.-II, mp 50-52$^{\circ}C$ were isolated from Korean ginseng extract by repeated column chromatographic purification. Comp-1 was identified as gomisin-N and Comp. -II as gomisin-A by spectrometric analysis, both of which have already been described as the anti-hepatotoxic lignin components of Schizandra chinensis Bail.

We isolated twelve lignans and three terpenoids were isolated from the n-hexane fraction of Schisandra chinensis extract. Using spectroscopic data and comparison with available literature, the following compounds were identified: (1) wuweizisu C, (2) gomisin N, (3) deoxyschisandrin, (4) gomisin A, (5) schisandrin, (6) chamigrenal, (7) schisanlactone D, (8) methylgomisin O, (9) angeloylgomisin O, (10) (-)-gomisin $L_2$, (11) schisandronic acid, (12) (-)-gomisin $L_1$, (13) (+)-gomisin $K_3$, (14) gomisin J, and (15) tigloylgomisin H. Notably, this was the first finding that compound (8) was isolated from this plant. Each compound was evaluated for its in vitro cytotoxic activities toward HL-60 (human leukemia), HeLa (human cervical carcinoma), and MCF-7 (breast cancer) cell lines. Compounds (7), (8), and (9) exhibited strong cytotoxic effects on HL-60 ($IC_{50}$ 7.37, 6.60, and $8.00{\mu}M$, respectively), whereas compound (6) exhibited weak cytotoxicity towards MCF-7 ($IC_{50}$ $30.50{\mu}M$). In addition, compound (8) showed the strongest activity towards HeLa cells ($IC_{50}$ $1.46{\mu}M$).

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.
