The present study has been undertaken to investigate the effect of the extract of Cirsium japonicum var. ussuriense leaves (CLE) on blood circulation in a rat model of topical ferric chloride ($FeCl_3$)-induced carotid artery damage. $FeCl_3$ treatment seriously damaged the carotid artery such as the walls of the artery, blood flow and inflammation. However, CLE administration has ameliorated blood circulation and suppressed vessel inflammation. CLE administration also has ameliorated the $FeCl_3$-induced artery tissue damage. Furthermore, CLE significantly suppressed the expression of adhesion molecules. These results suggest that CLE ameliorate blood circulation through suppress inflammatory mediator and adhesion molecule production.

Our previous report showed that polyacetylene compound, 1-Heptadecene-11, 13-diyne-8, 9, 10-triol (PA) from the root of Cirsium japonicum var. ussuriense has anti-inflammatory activity. In this study we investigated the role of the PA as inhibitor of caspase-1, which converts prointerleukin-$1{\beta}$ (proIL-$1{\beta}$) to active IL-$1{\beta}$ and is activated by inflammasome involved in the inflammatory process. We tested the effect of PA on the production of pro-inflammatory cytokines, IL-$1{\beta}$ in murine macrophage cell line, RAW264.7. PA inhibited lipopolysaccharide (LPS)-induced IL-$1{\beta}$ production by macrophages at a dose dependent manner. PA also suppressed the activation of caspase-1. The mRNA level of ASC (apoptosis-associated spec-like protein containing a CARD), an important adaptor protein of inflammasome, was decreased in the PA treated group. Therefore our results suggest that the anti-inflammatory effect of PA is due to inhibit the caspase-1 activation.

Cirsium japonicum var. ussuriense is often used in treatment of human disease such as hemorrhage, blood congestion and inflammation. The present study has been undertaken to investigate the effect of the leaf extract from C. japonicum var. ussuriense (CLE) on the development of collagen-induced arthritis (CIA) in DBA1/J mice. CLE administration suppressed markedly the arthritis incidence and arthritis score in CIA mice. Also, CLE significantly suppressed the release of $PGE_2$, TNF-${\alpha}$, IL-4 and IL-6 in CIA mice. However, CLE significantly increased the production of IL-10, but not IL-4. These results suggest that CLE suppress inflammatory mediators and regulates Th1 and Th2 cytokines. These properties may contribute to the anti-arthritis action of CLE.

A series of aqueous or methanol extracts from four different Korean salad plants were assayed to determine their allelopathy and antioxidant activity. The extracts applied on filter paper in a Petri-dish bioassay significantly inhibited root growth of against alfalfa (Medicago sativa) seedlings. Leaf extracts from 40 g dry tissue $L^{-1}$ of Aster yomena was most phytotoxic to alfalfa root growth, and followed by that of Cirsium japonicum, Taraxacum officinale, and Ixeris dentate. Methanol extracts of plants dose-dependently increased DPPH free radical scavenging activity in vitro. Antioxidant activity of methanol extracts from the same plant species was investigated, and the result showed high DPPH free radical scavenging activity in Cirsium japonicum, Aster yomena, and Ixeris dentate, however, in Taraxacum officinale was least activity. By means of HPLC analysis, chlorogenic acid, p-coumaric acid, and total phenolics with 7.68, 17.47 and 18.64 mg, $100g^{-1}$, respectively, showed the highest amounts in methanol extracts from Cirsium japonicum leaves. These results suggest that Compositae salad plants contain water-soluble substances with allelopathic potential as well as antioxidant activity.

This study investigated the chemical composition of Cirsium japonicum var. ussurience Kitamura essential oil and the quantitative changes of major volatile flavor compounds according to the harvesting season. The essential oils obtained by the method of hydrodistillation extraction from aerial parts of C. japonicum var. ussurience Kitamura were analyzed by GC and GC-MS. Sixty-four volatile flavor compounds were identified in the essential oil from C. japonicum var. ussurience Kitamura harvested in May 2012; hexadecanoic acid (49.31%) was the most abundant compound, followed by 6,10,14-trimethyl-2-pentadecanone (13.72%), phytol (13.40%) and 9-hexadecenoic acid (4.16%). Eighty-three compounds were identified in the essential oil from the plant harvested in October 2012; phytol (40.56%), hexadecanoic acid (17.69%), 6,10,14-trimethyl-2-pentadecanone (13.71%), and caryophyllene oxide (4.15%) were the most abundant compounds. Types and levels of volatile compounds from different harvesting seasons varied. The essential oil composition of C. japonicum var. ussurience Kitamura harvested in the spring and autumn was characterized by higher contents of aliphatic fatty acid, diterpene and sesquiterpene, respectively.

In this study, we isolated scopoletin from Cirsium setidens Nakai (Compositae) and tested its effects on melanogenesis. Scopoletin was not toxic to cells at concentrations less than $50{\mu}M$ and increased melanin synthesis in a dose-dependent manner. As melanin synthesis increased, scopoletin stimulated the total tyrosinase activity, the rate-limiting enzyme of melanogenesis. In a cell-free system, however, scopoletin did not increase tyrosinase activity, indicating that scopoletin is not a direct activator of tyrosinase. Furthermore, Western blot analysis showed that scopoletin stimulated the production of microphthalmia-associated transcription factor (MITF) and tyrosinase expression via cAMP response element-binding protein (CREB) phosphorylation in a dose-dependent manner. Based on these results, preclinical and clinical studies are needed to assess the use of scopoletin for the treatment of vitiligo.

This study was designed to elucidate the effects of Cirsium japonicum (CJ) extracts on hepatic stellate cells (HSCs, LX-2 cells) proliferation, which is induced by platelet-derived growth factor (PDGF) or transforming growth factor-${\beta}$ (TGF-${\beta}$). The content of total phenol, flavonoid, and silymarin derivatives was more higher in CJ-flower than in CJ-root. Consistent with these results, the LX-2 cells growth inhibition was more effective in CJ-flower extract than in CJ-root extract, the complete growth inhibition concentration was $1{\mu}g/mL$ and $50{\mu}g/mL$, respectively. These results suggest that extracts from CJ-flower can be potentially used as therapeutic substances for the regulatioin of HSCs activation.

Silibinin is the major active molecule of silymarin, the mixture of flavonolignans extracted from Cirsium japonicum (CJ). It has been used for treatment of hepatitis and inflammation related diseases. The aim of this study was to prove whether Silibinin has effectiveness for allergic inflammation. Silibinin processes the inflammatory reaction in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (PMA plus A23187) stimulated human mast cell line (HMC-1). Its effect was examined by ELISA, RT-PCR, Western blot, and Luciferase assay. The results were Silibinin inhibited the expression of histamine, TNF-$\alpha$ (tumor necrosis factor-$\alpha$), IL-6 (interleukin-6), and IL-8 (interleukin-8). Silibinin suppressed NF-${\kappa}B$ (nuclear factor kappa B) activation in stimulated HMC-1 (human mast cell-1). This effect was mediated through inhibition of phosphorylation and degradation of $IkB{\alpha}$, an inhibitor of NF-kB. Silibinin significantly inhibited induction of NF-kB promoter mediated Luciferase assay. These results suggest that Silibinin has a potential molecule for therapy of mast cell-derived allergic inflammatory diseases.
