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-1beta (proIL-1beta) to active IL-1beta and is activated by inflammasome involved in the inflammatory process. We tested the effect of PA on the production of pro-inflammatory cytokines, IL-1beta in murine macrophage cell line, RAW264.7. PA inhibited lipopolysaccharide (LPS)-induced IL-1beta 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.

Premenstrual syndrome is a common chronic disorder in most women of reproductive age. The main symptoms are depression, anxiety, tension, feeling out of control, and mastalgia. In premenstrual syndrome, the effects of aromatic edible Elsholtzia splendens and Cirsium japonicum were investigated for over 3 months in 30 women participants in their twenties. In the Elsholtzia splendens capsule treated group, scores of depression and anxiety were significantly lower than those in the Cirsium japonicum capsule treated group. Moreover, instability of the premenstrual assessment form was significantly decreased in the Elsholtzia splendens capsule treated group. Our results suggest that Elsholtzia splendens could be an effective plant material in relieving symptoms of premenstrual syndrome.

This study investigated the antioxidant activity of methanol (MeOH) and water extracts from roots of Cirsium japonicum in vitro. MeOH extract showed a stronger free 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 alpha-glucosidase inhibition assay. The water extract showed a considerable alpha-glucosidase inhibitory activity. To our knowledge, this may be the first time to report the antioxidant and antidiabetic activities in Cirsium japonicum roots.

The purpose of our study was to evaluate anti-AD potential of Cirsium maackii flowers. MeOH extract, CH2Cl2, EtOAc, and n-BuOH fraction of this flower notably inhibited BACE1 (IC₅₀ = 76.47 ± 1.66, 22.98 ± 1.45, 8.65 ± 0.63, and 72.47 ± 3.04 µg/mL, respectively). β-amyrenone (49.70 mg) (1), lupeol acetate (1.43 g) (2), lupeol (1.22 g) (3), lupenone (23.70 mg) (4), β-sitosterol (1.01 g) (6), and β-sitosterol glucoside (13.00 mg) (7) from CH₂Cl₂, apigenin (100.20 mg) (8), luteolin (19.00 mg) (9), apigenin 7-O-glucuronide methyl ester (21.30 mg) (14), and tracheloside (53.70 mg) (5) from EtOAc, apigenin 5-O-glucoside (11.00 mg) (10), luteolin 5-O-glucoside (11.00 mg) (11) and apigenin 7-O-glucuronide (91.00 mg) (12) from n-BuOH, and luteolin 7-O-glucuronide (22.00 mg) (13) from H₂O fraction were isolated. HPLC showed high levels of 8, 9 and 12 in MeOH extract (33.07 ± 0.07, 31. 44 ± 0.17 and 16.89 ± 0.33 mg/g, respectively), EtOAc (161.01 ± 1.78, 96.93 ± 0.34 and 73.38 ± 0.06 mg/g, respectively), and n-BuOH fraction (32.18 ± 0.33, 44.31 ± 0.32 and 105.94 ± 0.36 mg/g, respectively). Since, 3 and 9 are well-known BACE1 inhibitors, the anti-AD activity of C. maackii flower might be attributable to their presence.

OBJECTIVES: This study developed two weeks menu using temple foods, assessed preference for the menu among ordinary people, and determined the possibility of using temple foods to make out institutional food service menu. METHODS: To make out the menu, 153 typical types of temple food were selected, under several conditions, thus including balanced food groups, natural foods in season, preparation time, preparation methods, and foods appropriated for institutional foodservice. RESULTS: Developed menu contained 1905.8 kcal, had low fat content, high dietary fiber, vitamin, and mineral content, and good protein content in the nutritional respect, and fit protein requirements with low calorie content and high nutritional value. In the assessment of the food preference for 73 temple food items, most of the foods scored high (4 out of 5 points) for preference in general; therefore, the menu tended to be satisfied to the adults' preference. In particular, boiled rice (rice with chwi, rice with cirsium, rice with mushroom, rice with mushroom & vegetable and gimbap with tofu) and fried foods (fried shiitake with sweet & sour sauce and fried kelp) were highly preferred. CONCLUSIONS: The menu using temple foods can be a healthy choice for adults if it is well planned and managed. This study may be expected to provide basic data that would help developing menu to popularize temple foods. The above results could be applied at home as well as at foodservice institutes and furthermore could offer information for developing temple food products.

Luteolin 5-O-glucoside is the major flavonoid from Korean thistle, Cirsium maackii. We previously reported the anti-inflammatory activities of luteolin 5-O-glucoside in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In this study, we determined the anti-inflammatory mechanisms of luteolin 5-O-glucoside through the inhibition of nitric oxide (NO) production in vitro and in vivo. Results revealed that luteolin 5-O-glucoside dose-dependently inhibited NO production and expression of iNOS and COX-2 in LPS-induced RAW 264.7 cells. Luteolin 5-O-glucoside also significantly inhibited the translocation of NF-κB, the activation of MAPKs, and ROS generation in LPS-induced RAW 264.7 cells. In addition, protein expressions of Nrf-2 and HO-1 were also upregulated by luteolin 5-O-glucoside treatment. Moreover, luteolin 5-O-glucoside inhibited λ-carrageenan-induced mouse paw edema by 65.34% and 48.31% at doses of 50 and 100 mg/kg body weight, respectively. These findings indicate potential anti-inflammatory effect of luteolin 5-O-glucoside particularly by downregulating NF-κB and upregulating HO-1/Nrf-2 pathway.

Peroxynitrite (ONOO-)-scavenging activities of nine Compositae herbs consisting of three Ixeris, two Youngia, two Cirsium and one of each Lactuca and Taraxacum species were evaluated. The contents of their ONOO- scavengers in the extracts were also determined on a HPLC using seven standard compounds, chlorogenic acid (CGA), chicoric acid (CA), luteolin 7-glucoside (luteolin-7-glc), luteolin 7-glucuronide (luteolin-7-glcU), luteolin, linarin and pectolinarin. Five of those compounds exhibited potent ONOO--scavenging activities: IC50, CA (0.76 microM), CGA (1.34 microM), luteolin (0.81 microM), luteolin-7-glc (0.86 microM) and luteolin-7-glcU (3.13 microM). Both CA and luteolin-7-glc were highly contained in I. dentata (19.71 mg/g and 13.58 mg/g, respectively), I. dentata var. albiflora (17.58 mg/g and 23.83 mg/g, respectively) and I. sonchifolia (65.71 mg/g and 6.99 mg/g, respectively). Among the nine herbs, those three Ixeris species had very low IC50 values over the range of 0.48 - 1.74 microg/mL, suggesting that they could be potential therapeutic vegetables, particularly for preventing diabetic complications or obesity, which can be caused by an excess production of ONOO-.

Keratinocytes are constantly exposed to extracellular insults, such as ultraviolet B, toxic chemicals and mechanical stress, all of which can facilitate the aging of keratinocytes via the generation of intracellular reactive oxygen species (ROS). Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that plays a critical role in protecting keratinocytes against oxidants and xenobiotics by binding to the antioxidant response element (ARE), a cis-acting element existing in the promoter of most phase II cytoprotective genes. In the present study, we have attempted to find novel ethanol extract(s) of indigenous plants of Jeju island, Korea that can activate the Nrf2/ARE-dependent gene expression in human keratinocyte HaCaT cells. As a result, we identified that ethanol extract of Cirsium japonicum var. ussuriense Kitamura (ECJUK) elicited strong stimulatory effect on the ARE-dependent gene expression. Supporting this observation, we found that ECJUK induced the expression of Nrf2, hemoxygenase-1, and NAD(P)H:quinone oxidoreductase-1 and this event was correlated with Akt1 phosphorylation. We also found that ECJUK increased the intracellular reduced glutathione level and suppressed 12-O-tetradecanoylphorbol acetate-induced 8-hydroxyguanosine formation without affecting the overall viability. Collectively, our results provide evidence that ECJUK can protect against oxidative stress-mediated damages through the activation of Nrf2/ARE-dependent phase II cytoprotective gene expression.
