The berries of Schisandra chinensis (Schisandra fructus) are given the name Omiza in Korean (五味子), which translates as "five flavor fruit" because they possess all five basic flavors in Korean traditional herbal medicine: salty, sweet, sour, pungent (spicy), and bitter. It is used as a remedy for many ailments: to resist infections, increase skin health, and cure insomnia, coughing, and thirst. This study was designed to investigate the effects of Schisandra fructus butanol fraction (SFB) on serum lipid levels in hyperlipidemic mice. In this experiment, effects on total cholesterol, HDL-cholesterol, and triglyceride in serum were measured. In our results, SFB did not affect weight gain in hyperlipidemic mice. Oral administration of SFB lowered levels of total cholesterol and triglyceride, which were elevated by induction of hyperlipidemia. Finally, administration of SFB regulated changes in gene expression which were related to cell growth and differentiation.

The fruits of Schisandra chinensis have been used as an edible ingredient and traditional medicine in Korea. Due to morphological similarities of dried mature fruits, the correct identification of S. chinensis from other closely related Schisandrae species is very difficult. Therefore, molecular biological tools based on genetic analysis are required to identify authentic Schisandrae Fructus. Random amplifed polymorphic DNA (RAPD) and Sequence Characterized Amplified Region (SCAR) were used to develop an easy, reliable and reproducible method for the authentication of these four species. In this paper, we developed several RAPD-derived species specific SCAR markers and established a multiplex-PCR condition suitable to discriminate each species. These genetic markers will be useful to distinguish and authenticate Schisandrae Fructus and four medicinal plants, S. chinensis, S. sphenanthera, S. repanda and K. japonica, in species level.

Objectives : The original plant species of Schisandrae Fructus (O-mi-ja) is prescribed as Schisandra chinensis $B_{AILL.}$, in Korea, but S. chinensis $B_{AILL.}$ and S. sphenanthera $R_{EHD.}$ et $W_{ILS.}$ in China. Moreover, fruit of several other species in genus Schisandra also have been used as the same herbal medicines. To develop a reliable method for correct identification of Schisandrae Fructus and to evaluate the phylogenetic relationship of S. chinensis and its related species, we analyzed internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA (nrDNA). Methods : Twenty-four plant samples of three Schisandra species and one Kadsura species, S. chinensis $B_{AILL.}$, S. spenanthera $R_{EHD.}$ et $W_{ILS.}$, S. nigra $M_{ax.}$ and Kadsura japonica $D_{UNAL}$ were collected from each different native habitate and farm in Korea and China. The nrDNA-ITS region of each samples were amplified using ITS1 and ITS4 primer and nucleotide sequences were determined after sub-cloning into the pGEM-Teasy vector. Authentic marker nucleotides were estimated by the analysis of ClastalW based on the entire nrDNA-ITS sequence. Results : In comparative analysis of the nrDNA-ITS sequences, we found specific nucleotide sequences including indels (insertions and deletions) and substitutions to distinguish C. chinensis, S. spenanthera, S. nigra, and K. japonica. These sequence differences at corresponding positions are avaliable nucleotide markers to determine the botanical origin of O-mi-ja. Moreover, we evaluated the phylogenetic relationship of four plant species by the analysis of nrDNA-ITS sequences. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by the providing of definitive information that can identify each plant species and distinguish it from unauthentic adulterants for O-mi-ja.

The fruits of Schisandra chinensis and Prunus mume have been traditionally used in the Oriental countries as an astringent against diarrhea and abdominal pain, a protectant for liver disease, an antimicrobial, and a blood tonic. However, little is known about the extract of Schizandrae Fructus and Mume Fructus (SMF-Ex) on dextran-sulfate sodium (DSS)-induced colitis in mice. In this study, we investigated the protective effects of SMF-Ex on DSS-induced colitis in mice. An experimental colitis was induced by daily treatment with 5% DSS. SMF-Ex was orally administrated the single dose (80 mg/kg, body weight/day) for 7 days with one time per day. SMF-Ex reduced significantly clinical sign of DSS-induced colitis, including body weight loss, shorten colon length, increased disease activity index (DAI), and histological colon injury. SMF-Ex also inhibited significantly nitric oxide (NO) and prostaglandine $E_2$ ($PGE_2$) productions in DSS-induced colitis mice. Furthermore, SMF-Ex increased significantly an superoxide anion (SOD), catalase, and glutathione peroxidase (Gpx) activity of the colon tissue in DSS-induced colitis mice. These results suggest that SMF-Ex administration could reduce significantly the clinical signs and inflammatory mediators, and increase antioxidant activity in DSS-induced colitis model mice and is a good candidate for further evaluation as an effective anti-ulcerative agent.

Disturbance of antioxidant system is very common in chronic alcoholics and herbal or natural products with antioxidant activity have been used for its treatment. This study was to investigate the effect of Vitis vinifera extract(V), Schisandra chinensis extract(S), Taraxacum officinale extract(T), Gardenia jasminoides extract(G), Angelica acutiloba extract(A) and Paeonia japonica extract(P), and their combinations on the antioxidant and ethanol oxidation system. Male Sprague-Dawley rats were subjected to Lieber-DeCarli ethanol liquid diet(ED) and were then given different herbal extract mixtures for 6 weeks including VST(V 100+S 150+T 150mg/kg/day), VSG(V 100+S 150+G 150mg/kg/day), VTG(V 100+T 150+G 150mg/kg/day), and VAP(V 100+A 150+P 150mg/kg/day). When the activity of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH) were compared between ED only group and herbal extracts treatment group, the differences were statistically significant. Phase I and II(glutathione-S-transferase, phenol sulfatransferase) enzyme activities were found to be significantly higher in the VAT treatment group compared to the ED group. Herbal extracts not only repressed the ethanol-induced elevation of malondialdehyde level, but also protected against ethanol-induced decrease in glutathione content, glutathione reductase, glutathione peroxidase, catalase and superoxide dismutase activities. The administration of the herbal extracts was found to be effective in eliminating lipid-peroxides induced by long-term consumption of alcohol by activating various enzyme systems and physiological active compound formation system. After a chronic consumption of alcohol, Angelica Radix protected the liver via activating the ethanol-metabolism enzyme system, and Paeoniae Radix via activating the ethanol-metabolism enzyme and the phase I, II-metabolism enzyme system. Taraxaci Herba was also effective in liver protection via activating the ethanol-metabolism enzyme system and the phase I, II-metabolism enzyme system, Gardeniae Fructus via activating the phase II-metabolism enzyme system and the anti-oxidation system enzyme, and Schisandra Fructus and a grapestone via activating the anti-oxidation system. Our data suggest that these herbal extracts may be useful as a health functional food or new drug candidate for fatty liver and hepatotoxicity induced by chronic alcohol consumption.

BACKGROUND/OBJECTIVES: Benign prostatic hyperplasia (BPH) characterized by an enlarged prostate gland is common in elderly men. Corni Fructus (CF) and Schisandrae Fructus (SF) are known to have various pharmacological effects, including antioxidant and anti-inflammatory activities. In this study, we evaluated the inhibitory efficacy of CF, SF, and their mixture (MIX) on the development of BPH using an in vivo model of testosterone-induced BPH. MATERIALS/METHODS: Six-week-old male Sprague-Dawley rats were randomly divided into seven groups. To induce BPH, testosterone propionate (TP) was injected to rats except for those in the control group. Finasteride, saw palmetto (SP), CF, SF, and MIX were orally administered along with TP injection. At the end of treatment, histological changes in the prostate and the level of various biomarkers related to BPH were evaluated. RESULTS: Our results showed that BPH induced by TP led to prostate weight and histological changes. Treatment with MIX effectively improved TP-induced BPH by reducing prostate index, lumen area, epithelial thickness, and expression of BPH biomarkers such as 5α-reductase type 2, prostate-specific antigen, androgen receptor, and proliferating cell nuclear antigen compared to treatment with CF or SF alone. Moreover, MIX further reduced levels of elevated serum testosterone, dihydrotestosterone, and prostate-specific antigen in BPH compared to the SP, a positive control. BPH was also improved more by MIX than by CF or SF alone. CONCLUSIONS: Based on the results, MIX is a potential natural therapeutic candidate for BPH by regulating 5α-reductase and AR signaling pathway.

Muscle atrophy, known as a sarcopenia, is defined as a loss of muscle mass resulting from a reduction in muscle fiber area or density due to a decrease in muscle protein synthesis and an increase in protein breakdown. Many conditions are associated with muscle atrophy, such as aging, denervation, disuse, starvation, severe injury and inflammation, prolonged bed rest, glucocorticoid treatment, sepsis, cancer, and other cachectic diseases. On the other hand, osteoarthritis (OA) is the most common form of joint disease and is wide spread in the elderly population and is characterized by erosion of articular cartilage, osteophyte formation, and subchondral bone sclerosis. The cytokine network plays an important role in the development and progression of OA with the inflammatory cytokine. Schisandrae Fructus (SF) derived from the ripe fruit of Schisandra chinensis (Turcz.) Baill. (Magnoliaceae) has been extensively used in traditional herbal medicines in Asia. It was originally used as a tonic and has been traditionally used for the treatment of many uncomfortable symptoms, such as cough, dyspnea, dysentery, insomnia, and amnesia for a long time. Previous reports have shown that SF and its related compounds possess various biological activities such as antioxidant, anti-inflammatory, anticancer, anti-microbial, antiseptic, anti-aging, hepatoprotective and immunostimulating effects. However, the therapeutic effects of SF on muscle atrophy and OA has not yet been evaluated. In the present study, we aimed to determine whether extracts of SF, the dried fruit of S. chinensis, mitigates the development of muscle atrophy and OA.

Muscle atrophy, known as a sarcopenia, is defined as a loss of muscle mass resulting from a reduction in the muscle fiber area or density due to a decrease in muscle protein synthesis and an increase in protein breakdown. Schisandrae fructus (SF) extract of the fruits of Schisandra chinensis (Turcz) Baillon has been used as a tonic in traditional medicine for thousands of years. Although a great deal of work has been carried out on the therapeutic potential of SF, its pharmacological mechanisms of action in muscle diseases actions remain unclear. In the present study, we investigated the inhibitory effects of SF ethanol extracts on the production of muscle atrophy factors in C2C12 myotubes stimulated with 5-aminoimidazole-4-carboxamide-ribonucleotide (AICAR), an AMP-activated kinase (AMPK) activator, and sought to determine the underlying mechanisms of action. AICAR upregulated atrophy-related ubiquitin ligase muscle RING finger-1 (MuRF-1) and stimulated the levels of the forkhead box O3a (FoxO3a) transcription factor in the C2C12 myotubes. SF supplementation effectively and concentration- dependently counteracted AICAR-induced muscle cell atrophy and reversed the increased expression of MuRF-1 and FoxO3a. Our study demonstrates that SF can reverse the muscle cell atrophy caused by AICAR through regulation of the AMPK and FoxO3a signaling pathways, followed by inhibition of MuRF-1.
