  • This study investigated the antioxidant activity of methanol (MeOH) and water extracts from roots of Cirsium japonicum in vitro, MeOH extract showed a stronger tree radical scavenging activity than water extract. However, both of extracts showed a concentration dependent hydroxyl radical scavenging activity, reducing power and metal chelating ability, MeOH extract had greater phenolic and flavonoid contents than water extract. The antidiabetic activity of these two extracts was evaluated by the a-glucosidase inhibition assay, The water extract showed a considerable a-glucosidase inhibitory activity. To our knowledge, this may be the first time to report the antioxidant and antidiabetic activities in Cirsium japonicum roots.

  • Cirsium japonicum var. ussuriense are often used in treatment of human diseases such as hemorrhage, blood congestion and inflammation in Korea. However, there was not report on the anti-obesity efficacy of water extracts from different organs of C. japonicum var. ussuriense. Here, we investigated the antioxidant effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense. Total polyphenol amounts of the flower extract showed higher than those of leaf and root extract. Flower extract also showed the high antioxidant activities such as DPPH radical scavenging activity and reducing power. We also investigated the anti-obesity effects of water extracts of flowers, leaves and roots from C. japonicum var. ussuriense in 3T3-L1 cells and high fat diet-induced obesity mice. The mice were divided into four groups [high fat diet (HFD) control, HFD + leaf extract, HFD + flower extract and root extract] and administered with each extract (200 mg/kg) for 12 weeks. The flower and leaf extract significantly suppressed the levels of oil red O and triglyceride content. The flower and leaf extract also significantly reduced the triglyceride, total cholesterol and lower density lipoprotein levels of plasma as well as body and abdominal fat weight. Furthermore, oral glucose tolerance in the flower and leaf extract groups were significantly ameliorated in comparison to the high fat diet group. Therefore, these results indicate that the flower and leaf extract could ameliorate obesity and attenuate blood glucose level in high fat diet-induced obesity mice. We conclude that this study may provide positive insights into water extracts of flowers and leaves from C. japonicum var. ussuriense as a functional food ingredient for treatment of obesity.

  • Objective: The roots, leaves, flowers, stems and seeds of Cirsium japonicum var. ussuriense are often used in treatment of human diseases such as hemorrhage, blood congestion and inflammation. Focusing our attention on natural and bioavailable sources of antioxidants and anti-inflammation, we undertook to investigate the antioxidant and anti-inflammatory properties of Cirsium japonicum var. ussuriense used as a folk medicine in Korea. Methods: The extracts of the leaves, stems, flowers, seeds and roots from C. japonicum var. ussuriense were prepared by extracting with water or 80% ethanol. Total flavonoids and polyphenols were measured by a colorimetric assay. The free radical scavenging activity of the extract was analyzed by the DPPH (1,1-diphenyl-2-picryl hydrazyl), ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) and Griess reagent assay. An oxidative product of nitric oxide (NO), was measured in the culture medium by the Griess reaction. The level of prostaglandin $E_2$ ($PGE_2$) was measured by enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were measured by Western blot analysis. Results: Total flavonoid and polyphenol amounts of the leaves (CLE) and flowers (CFE) showed higher than those of the seed extract (CSE), stem extract (CSTE) and roots (CRE). CLE and CFE also showed the high antioxidant activities such as DPPH, NO-like and ABTS radical scavenging activity. An antioxidant activities of these water extracts showed higher than those of 80% ethanol extracts. We investigated the anti-inflammatory effects of CLE on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. CLE significantly suppressed the levels of the inflammatory mediators such as NO and prostaglandin $E_2$ ($PGE_2$) in dose dependant. Furthermore, the levels of iNOS and COX-2 protein expressions were markedly suppressed by the treatment with CLE extract in a dose dependent manner. Conclusions: These results suggest that CLE water extract has a higher anoxidant and anti-inflammatory activity, these properties may contribute to the oxidative and inflammatory related disease care.

  • Cirsium japonicum belongs to the Asteraceae or Compositae family and is a medicinal plant in Asia that has a variety of effects, including tumour inhibition, improved immunity with flavones, and antidiabetic and hepatoprotective effects. Silymarin is synthesized by 4-coumaroyl-CoA via both the flavonoid and phenylpropanoid pathways to produce the immediate precursors taxifolin and coniferyl alcohol. Then, the oxidative radicalization of taxifolin and coniferyl alcohol produces silymarin. We identified the expression of genes related to the synthesis of silymarin in C. japonicum in three different tissues, namely, flowers, leaves, and roots, through RNA sequencing. We obtained 51,133 unigenes from transcriptome sequencing by de novo assembly using Trinity v2.1.1, TransDecoder v2.0.1, and CD-HIT v4.6 software. The differentially expressed gene analysis revealed that the expression of genes related to the flavonoid pathway was higher in the flowers, whereas the phenylpropanoid pathway was more highly expressed in the roots. In this study, we established a global transcriptome dataset for C. japonicum. The data shall not only be useful to focus more deeply on the genes related to product medicinal metabolite including flavolignan but also to study the functional genomics for genetic engineering of C. japonicum.

  • Background: The roots of Cirsium japonicum var. ussuriense (RCJ) have been used as traditional medicine in Korea for hematuria and hematemesis. These extracts exert anti-oxidative and anti-inflammatory effects by scavenging for free radical and regulating the inflammatory response. However, the effect of RCJ on rheumatoid arthritis (RA) has not been elucidated. Thus, we evaluated the water extract of RCJ (WRCJ) using type II collagen-induced RA models. Methods and Results: RA was induced by immunization with type II collagen. All experimental materials were orally administered daily for three weeks. The positive control group was administered with 0.2 mg/kg methotrexate (n = 7), while the experimental group was administered with WRCJ (100 or 500 mg/kg, n = 7). Serum levels of TNF-alpha, Interleukin 6 (IL-6), and type II collagen IgG (CII) were measured using ELISA. Administration of 500 mg/kg WRCJ decreased the levels of TNF-alpha, IL-6, and CII. Moreover, WRCJ treatment diminished swelling of hind legs and infiltration of inflammatory cells in RA models' synovial membrane. Conclusions: These results indicate that WRCJ could improve RA, reduce inflammatory indicators and synovial inflammation. However, further experiments are required to determine how WRCJ can influence the signal transduction pathway in RA.

  • 이삭마름병은 지금까지 화학살균제에 의해 방제되어 왔지만 잔류농약 문제로 인하여 합성농약의 사용은 곡류 수확 30일 전까지로 그 처리기간이 제한되어 있다. 따라서 수확 직전까지 처리가 가능한 새로운 생물농약의 개발이 필요하다. 본 연구에서는 이삭마름병 방제를 위하여 F. graminearum에 대하여 항균활성을 보이는 식물추출물을 선발하기 위하여 총 85과에속하는 225 한약재시료의 ethanol 추출물을 대상으로 F. graminearum 포자발아 억제효과를 조사하였다. 그 결과 높은 억제활성을 가진 대계근을 선발한 후, 용매 분획, 컬럼 크로마토그래피와 생물검정을 거쳐 F. graminearum 포자발아 억제활성을 가진 두 개의 화합물을 분리하였다. 두 물질은 질량분석과 핵자기공명분석을 통하여 ciryneol C와 1-heptadecene-11,13-diyne-8,9,10-triol의 polyacetylene계 화합물로 동정되었다. F. graminearum의 포자발아 저해활성을 나타내는 $IC_{50}$은 1-heptadecene-11,13-diyne-8,9,10-triol이 $3.17{\mu}g/ml$, ciryneol C는 $28.14{\mu}g/ml$로 1-heptadecene-11,13-diyne-8,9,10-triol의 저해활성이 ciryneol C보다 더 높았다. 또한 온실에서의 대계근 EtoAc 추출물 분말수화제의 밀 이삭마름 병방제효과는 250배와 500배희석액처리시각각 78.92%와 31.56%로 유효성분의 농도가 높을수록 방제효과도 높아졌다. 본 연구결과는 polyacetylene계 화합물을 함유하는 대계근의 조추출물이 이삭마름병 방제를 위한 식물유래 천연물 살균제로 사용이 가능하다는 것을 제시하고 있다.

  • Phenolics level, total flavonoid content, and antioxidant were determined from the methanol extracts of the eight medicinal plants using roots. Total phenolics were found as the highest levels in the methanol extracts of Arctium lappa, and followed by Youngia sonchifolia and Cirsium japonicum. Total amount of the each phenol compounds were detected in C. japonicum extracts ($319.2\;mg\;kg^{-1}$) as the greatest component, and followed by A. lappa ($96.3\;mg\;kg^{-1}$) and Y. sonchifolia ($22.9\;mg\;kg^{-1}$). Total flavonoid content showed the highest amount in methanol extracts from A. lappa (68.1 mg $100\;g^{-1}$) and followed by Y. sonchifolia (11.2 mg $100\;g^{-1}$) Lycoris radiate extracts (87.2%) had the highest nitrite scavenging activity and followed by A. lappa (81.5%) and Y. sonchifolia (77.5%). Methanol extracts of A. lappa at 25 mg $100\;g^{-1}$ exhibited the highest DPPH radical scavenging activity by 90.8%, even though less activity than synthetic antioxidants Vitamin C or butylated hydroxytoluene (BHT). Level of polyphenols was highly correlated with anti oxidative activity ($r^2$ = 0.85). The results suggest that several medicinal plants selected had the potent biological activities, and that their activities were differential depending on plant species.
