Schisandra chinensis containing a variety of pharmacologically active lignans has been traditionally used in oriental medicine. In this study, anti-inflammatory compounds were screened from the hexane extracts of S. chinensis by activity-guided fractionation. First, we investigated the regulatory effects on the expression of E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) with 38 fractions from the hexane extracts of S. chinensis in human umbilical vein endothelial cells (HUVECs). As a result, SCKH1 among the 38 fractions from the hexane extract of S. chinensis was selected for further analysis based on its unique regulatory effect on cell adhesion molecules, especially on VCAM-1, in LPS-stimulated HUVECs. The subsequent activity-guided fractionation of SCKH1 resulted in the purification of SCKH1PAIBPB, which was found to suppress the expression of VCAM-1, MCP-1, IL-6 and IL-8 in HUVECs stimulated with LPS, and to inhibit the adhesive capacity between HUVECs and monocytes. Taken together, our data indicate that SCKH1PAIBPB can be proposed as an effective anti-inflammatory compound that may have a potential therapeutic use for the prevention and treatment of various inflammatory diseases as well as ischemic vascular diseases.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel with modest permeability to calcium ions. It is involved in intracellular calcium signaling and is therefore important in processes such as thermal sensation, skin barrier formation, and wound healing. TRPV3 was initially proposed as a warm temperature sensor. It is activated by synthetic small-molecule chemicals and plant-derived natural compounds such as camphor and eugenol. Schisandra chinensis (Turcz.) Baill (SC) has diverse pharmacological properties including antiallergic, anti-inflammatory, and wound healing activities. It is extensively used as an oriental herbal medicine for the treatment of various diseases. In this study, we investigated whether SC fruit extracts and seed oil, as well as four compounds isolated from the fruit can activate the TRPV3 channel. By performing whole-cell patch clamp recording in HEK293T cells overexpressing TRPV3, we found that the methanolic extract of SC fruit has an agonistic effect on the TRPV3 channel. Furthermore, electrophysiological analysis revealed that ${\gamma}$-schisandrin, one of the isolated compounds, activated TRPV3 at a concentration of $30{\mu}M$. In addition, ${\gamma}$-schisandrin (${\sim}100{\mu}M$) increased cytoplasmic $Ca^{2+}$ concentrations by approximately 20% in response to TRPV3 activation. This is the first report to indicate that SC extract and ${\gamma}$-schisandrin can modulate the TRPV3 channel. This report also suggests a mechanism by which ${\gamma}$-schisandrin acts as a therapeutic agent against TRPV3-related diseases.

This study investigated the hair growth effect of Schisandra chinensis extract (TS-SC) and TS-SC fermented by Lactobacillus plantarum (TS-SCLF) on human dermal papilla cells (hDPCs). The production of vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1), keratinocyte growth factor/fibroblast growth factor 7 (KGF/FGF-7) and hepatocyte growth factor (HGF), transforming growth factor beta 1 (TGF-β1) were examined. The secretion rates of VEGF and KGF/FGF-7 were high in TS-SC, and the secretion rates of IGF-1 and HGF were high in TS-SCLF. TGF-β1 was inhibited in a concentration-dependent manner in all samples. Gene expression of VEGF, IGF-1, KGF, HGF and alkaline phosphatase, relevant to hair growth, were examined. The data revealed that TS-SC and TS-SCLF successfully promoted hair growth in hDPCs. The IGF-1 gene was expressed in a dose-dependent manner in TS-SCLF. These results indicate that TS-SC and TS-SCLF fermented extract effectively promoted hair growth and gene expression relevant to hair growth in hDPCs. Used in clinical trials the test substance 'CMK-LPF01' showed a statistically significant increase in the number of hairs at 8 weeks, 16 weeks, and 24 weeks compared to before product use, and a change in hair growth, a secondary efficacy evaluation variable. Through additional research in the future, it is expected that "CMK-LPF01" can be developed as a functional material that can help alleviate symptoms of hair loss.

In this study, the optimal extraction conditions for three medicinal herbs as functional sources against inflammatory and arthritic diseases were developed. Traditional medicinal herbs were screened for their inhibition of hyaluronidase (HAse) activity and nitric oxide (NO) synthesis. For the screening of anti-inflammatory properties, ethanolic extracts of 53 species of traditional medicinal herb were examined. We confirmed that Astragalus membranaceus (A.R.), Schisandra chinensis (S.F.), and Platycodon grandiflorum (P.G.) inhibit NO production. For extraction from all three herbs simultaneously, an ethanol concentration of 95%, a 1:2:1 mixture ratio, and at 50 rpm mixing speed, for over 12 h and at $30^{\circ}C$ was the best condition for optimal extract yield and NO inhibition effects. HAse inhibition from the three herb extraction was three fold higher than single samples. The ethanol extracts were fractionated with various solvents (n-hexane, chloroform, ethyl acetate, n-butanol, and water). The ethyl acetate-soluble fraction of the herb mixture showed the highest extract yield (13%) and NO inhibition effects (73%). In conclusion, this study provides experimental evidence that a mixture of P.G., A.R., and S.F. could be used as a source of antioxidant ingredients in the food industry.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

BACKGROUND/OBJECTIVES: This study evaluated the effects and molecular mechanisms of the Schisandra chinensis fruit extract (SC) and its major compound gomisin A (GA), on the contractility of rabbit penile corpus cavernosum smooth muscle (PCCSM). MATERIALS/METHODS: PCCSM was exposed to SC or GA after appropriate pretreatment with nitric oxide synthase (NOS) blocker, guanylate cyclase blocker, adenylyl cyclase blocker or protein kinase A blocker. Subsequently, we evaluated the cyclic nucleotide in the perfusate by radioimmunoassay, protein expression level of neuronal NOS (nNOS) and endothelial NOS (eNOS) by western blot, and the interaction of SC or GA with udenafil and rolipram. RESULTS: Both SC and GA induce PCCSM relaxations in a concentration-dependent manner. Pretreatment with NOS blocker, guanylate cyclase blocker, adenylyl cyclase blocker or protein kinase A blocker result in significantly decreased relaxation. SC and GA also induce the levels of cyclic nucleotide in the perfusate in a concentration-dependent manner. Perfusion with GA also showed significantly higher levels of eNOS protein. Furthermore, the udenafil and rolipram induced relaxations of PCCSM were enhanced after exposure to SC and GA. Our results indicate that SC and GA induce the relaxation of PCCSM via the nitric oxide (NO)-cGMP and cAMP signaling pathways. CONCLUSIONS: The SC and GA are potential alternative treatments for men who want to consume natural products to ameliorate erectile function, or who do not respond to the commercially available medicines.

A major polyphenolic compound extracted from omija (Schisandra chinensis) fruit was structurally identified, and its composition of major nutrients was investigated as well in this study. A dominating high performance liquid chromatography (HPLC) peak of water-extracted anthocyanin represented 94.1% of total absorbable compounds at 520 nm, which was further identified with HPLC-mass spectrometry (MS). As a result, mass-to-charge ratio (m/z) of the predominant anthocyanin was determined to be 727, and it was identical to molecular mass of cyanidin-3-xylosylrutinoside (Cya-3-O-xylrut). This is the first report that colorant of omija is predominantly composed of Cya-3-O-xylrut. Omija fruit contained exclusively 3 types of monosaccharide such as glucosc (0.68 g), galactose (0.01 g), and fructose (0.52 g) per 100 g of fruits. Several organic acids, citric (3.29 g), malic (1.4 g), acetic (0.4 g), and succinic acids (0.36 g) per 100 g of fruits, were detected by high performance anion exchange chromatography (HPAEC) analysis. During the compositional analysis of tree amino acid by HPLC, it was noticed that omija fruit contained substantial amount (0.01 g/100 g of fruits) of $\gamma$-amino butyric acid (GABA).

Reflux extraction properties of Schisandra chinensis were investigated with different extraction conditions of ethanol concentration (0-99%), extraction time (2-8 h), and extraction temperature ($40-100^{\circ}C$). Different chemical properties, such as reducing sugars (RS), titratable acidity (TA), Hunter's color values, total phenolic compounds (TPC), and antioxidant activity (DPPH and ABTS assays) were analyzed for the corresponding extracts. The results showed that RS and TA increased as the extraction temperature increased. For each parameter, the maximum value was achieved, when extraction was carried out with 50% ethanol for 8 h at $100^{\circ}C$. Redness ($a^*$) of the extract decreased as all 3 extraction parameters were increased. TPC increased significantly as the extraction time and temperature increased; further, the highest TPC was achieved, when extraction was carried out with 50% ethanol. The same tendency was observed for DPPH and ABTS radical scavenging activities. The highest TPC and antioxidant activity were obtained, when extraction was carried out with 50% ethanol for 4-6 h at $60-80^{\circ}C$, respectively.
