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.

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.

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 $50\;{\mu}g/ml$.

Two compounds from Gomisin N and Gomisin A were isolated from the fruits of Schizandra chinensis Baillon. The highest extraction yield as 21.36% was observed in the ethanol extract, compared to the yield obtained form the water extract. The extraction yields of the single compounds were measured to be 0.13 and 0.014 Gomisin A and Gomisin N, respectively. Approximately, 90% of the growth of human stomach adenocarcinoma cancer cells was inhibited after adding 1.0 g/l of the ethanol extract. The growth of the human normal lung cell was limited to 24% after adding the ethanol extract. The water extract lowered the specific secretion of $TNF-\acute{a}$ and IL-6 from T cells, $10.3{\times}10^{-4}\;pg/cell\;and\;12.1{\times}10^{-4}\;pg/cell$, respectively, compared to the ethanol extracts. On the other hand, a treatment with the ethanol extract increased the specific secretion of $TNF-\acute{a}$ and IL-6 from human T cells, to $11{\times}10^{-4}\;pg/cell\;and\;14.3{\times}10^{-4}\;pg/cell$, respectively. The crude ethanol extract had the highest effect on the differentiation of human promyelocytic leukemia cells compared to the other extracts and Gomisin A and N. In general, the biological activities of the extracts gradually decreased as the purification process proceeded, which suggests that higher immunostimulatory activities can be maintained by adding the crude extracts of the fruits rather than by adding a single compound.

오미자의 헥산 추출물로부터 dibenzocyclooctadiene류인 schisandrin 1143.7 mg, schisandrin C 317.3 mg, gomisin A 261.4 mg 및 gomisin N 213.4 mg을 순수분리하여 구조를 동정하였다. 각각의 리그난은 $^1H$-NMR, $^{13}C$-NMR 및 GC-MS 스펙트럼으로부터 구조를 동정하였다. 오미자로부터 분리한 schisandrin, schisandrin C, gomisin A 및 gomisin N을 $10^{-5}\;M$, $10^{-6}\;M$ 및 $10^{-7}\;M$로 조정한 용액에 1시간 침지 후 발아율을 비교하였다. Gomisin A의 처리 시 모든 농도에서 발아율이 억제되었고, 농도가 높을수록 발아 억제효과가 높았다. Gomisin N처리 시에는 대조구에 비하여 모든 농도에서 발아율이 높았다. 리그난 처리 48시간 후 발아율은 대조구와 비교한 결과, schisandrin C와 gomisin A는 발아율을 억제하였다. 따라서 오미자로부터 추출한 리그난은 종자발아를 촉진시키는 효과가 있었고, 이차대사산물로서는 많이 함유되어 있으므로 생장조절제로서 이용가능이 있을 것으로 기대한다.

BACKGROUND/OBJECTIVES: Male hypogonadism is a condition where the body does not produce enough testosterone and significantly impacts health. Age, obesity, genetics, and oxidative stress are some physiological factors that may contribute to testosterone deficiency. Previous studies have shown many pharmacological benefits of Schisandra chinensis (S. chinensis) Baillon as an anti-inflammatory and antioxidant. However, the molecular mechanism of attenuating hypogonadism is yet to be well established. This research was undertaken to study the effects of S. chinensis extract (SCE) on testosterone deficiency. MATERIALS/METHODS: S. chinensis fruit was pulverized and extracted using 60% aqueous ethanol. HPLC analysis was performed to analyze and quantify the lignans of the SCE. RESULTS: The 2,2-diphenyl-2-picrylhydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging assays confirmed that the SCE and its major lignans (schisandrol A and gomisin N) inhibit oxidative stress. Effects of SCE analysis on the testosterone level under oxidative stress conditions revealed that both schisandrol A and gomisin N were able to recover the lowered testosterone levels. Through mRNA expression of TM3 Leydig cell, we observed that the SCE lignans were able to induce the enzymes involved in testosterone biosynthesis-related genes such as 3β-HSD4 (P < 0.01 for SCE, and P < 0.001 for schisandrol A and gomisin N), 17β-HSD3 (P < 0.001 for SCE, schisandrol A and gomisin N), and 17, 20-desmolase (P < 0.01 for schisandrol A, and P < 0.001 for SCE and gomisin N). CONCLUSIONS: These results support that SCE and its active components could be potential therapeutic agents for regulating and increasing testosterone production.

Schisandra chinensis is a traditional herbal medicine that is widely spread in Korea, Japan, and China. The fruits of S. chinensis Bailon, known as omija in Korea, have traditionally been used for the treatment of coughs, fatigues, and insomnia. Up to now, there have been several reports for the identification of major lignan compounds and their quantitation in S. chinensis extracts. To the best of our knowledge, however, there is no report on the analysis of lignans in omija wine and omija cheong (sugared omija or omija sugar syrup). In the present study, seven dibenzocyclooctadiene lignans (gomisin A, gomisin B, gomisin C, gomisin N, schisandrin, deoxyschisandrin, and wuweizisu C) in omija wine and omija cheong were analyzed and quantitated using liquid chromatography-tandem mass spectrometry. Among seven lignans, pharmacologically active gomisin A, schisandrin, and deoxyschisandrin, which are major components in fruits of S. chinensis, were the most abundant lignans in omija wine and cheong. The content of lignan in omija wine was in the order: schisandrin > gomisin A > deoxyschisandrin > gomisin N > gomisin B > gomisin C > wuweizisu C. The concentration of deoxyschisandrin and gomisin N in omija wine was approximately 2.0- and 6.0-fold higher than for omija cheong. Additionally, this study provided a systematic identification of lignans in omija wine and cheong and indicated that the omija wine and cheong might be of value for their dietary application.
