Xanthium sibiricum using extracts antioxidant activity and antimicrobial activity were analyzed and the following results were obtained. Antioxidant activity using DPPH as a VLC column fractionation experiments XS-5 (water fraction of Xanthium sibiricum) concentration in the 500 ${\mu}g/ml$ to 87.53 percent in the highest antioxidant activity was found, VLC fractionation in XS-3-2 (eluted with chloroform/methanol 7~10%) concentration of 500 ${\mu}g/ml$, showed the antioxidant activity of 78.72%. The antioxidant activity measured by PCL XS-1 (n-hexane fraction of Xanthium sibiricum) XS-5 (water fraction of Xanthium sibiricum) and 13.32 nmol open column XS-3-2 (eluted with chloroform/methanol 7~10%) showed antioxidant activity with 14.34 nmol. The antimicrobial activity against Candida albicans XS-2 (methlene chloride fraction fo Xanthium sibiricum) is the concentration of 500 ${\mu}g$/disc 1 mm of the clean zone was formed. XS-3 (ethanol fraction fo Xanthium sibiricum) in the antioxidant activity using DPPH and PCL had higher antibacterial activity was low.

Purpose: The aim of this study is to evaluate the effect of Xanthium sibiricum Patr. on carcinogenesis. Method: Water extract from Xanthium sibiricum Patr. (XPW) was prepared and investigated for the potential antitumor activity and inhibition of benzo[a]pyrene-DNA adduct formation and free radical formation. Result: It was shown that the water possess considerable toxicity toward tumor cell lines. Concentration of XPW at 1.0 mg/mL and 2.5 mg/mL resulted in more than 30% inhibition of growth in HeLa cells. Toxicity of XPW to A549 revealed that 54% inhibition of growth at concentration of 2.5 mg/mL. At concentrations of 0.5 mg/mL, 1.0 mg/mL and 2.5 mg/mL of XPW, the binding of [$^3H$]B[a]P metabolites to DNA of human Chang cell was inhibited by 19%, 33%, and 41%, respectively. There 18% and 32% inhibition in the free radical formation with XPW at the concentration of 1.0 mg/mL and 2.5 mg/mL, respectively. Conclusion: Water extract from Xanthium sibiricum Patr. (XPW) has antitumor and cancer chemopreventive activities.

Xanthium sibiricum is used as a traditional folk medicine for the treatment of cancer, fever, headache, nasal sinusitis, and skin pruritus. This study aimed to identify components from Xanthium sibiricum extracts using an SPE-800MHz NMR-MS hyphenated system. The simultaneous acquisition of MS and NMR spectra from the same chromatographic peaks significantly increases the depth of information acquired for the compound and allows the elucidation of structures that would not be possible using MS or NMR data alone. LC -NMR analysis was conducted using a HPLC separation system coupled to 800 MHz spectrometer equipped with a cryoprobe, and a SPE unit was used to automatically trap chromatographic peaks using a HPLC pump. LC-MS analysis was conducted with a Q-TOF MS instrument using ESI ionization in the negative ion mode. Using the hyphenated analysis, several secondary metabolites were identified, such as 3',5'-O-dicaffeoylquinic acid, 1',5'-O-dicaffeoyl- quinic acid, and ethyl caffeate. These results demonstrate that the SPE-800MHz NMR-MS hyphenated system can be used to identify metabolites within natural products that have complex mixtures.

Herba Xanthii(HX), Radix Xantluii(RX) and Fructus Xanthii(FX) is one of the oriental medicine that has been used for the treatment of such infectious diseases and tumors. However, the mechanism of the drug is not investigated much. This study was done to know the effects of HX, RX and FX extract on the such innate immunities as phagocytic function and reactive radical formtions from phagocytes and the such acquired immunities as humoral and cell-mediated immunities. The followings are the results obtained from this study: 1. HX2 and FX1 groups increases the in vivo phagocytic activity of mononuclear phagocytes. 2. HXB, RXB, RXC, FXB and FXC groups increase the in vitro phagocytic activities. 3. RXB group stimulated the macrophages to produce nitric oxide in the presence of $interferon-{\gamma}$ $(IFN-{\gamma})$. 4. HX and RX whole groups increased the luminol-amplified reactive oxygen intermediate production in vivo. 5. HX whole and RX1, FX2 groups increased the lucigenin-amplified reactive oxygen intennediate production in vivo. 6. HXC group only increased the luminol-amplified reactive oxygen intermediate production in vitro. 7. HXB, FXB and FXC groups increased the lucigenin-amplified reactive oxygen intermediate production in vitro. 8. HX2, RX1 and FX whole groups increased the hemolysin formations from B cells. 9. HX, RX and FX whole groups significantly increased the rosette forming cells from the spleen. 10. HX, RX and FX whole groups significantly decreased the delayed-type hypersensitivity measured by footpad swelling. The above results demonstrate that HX, RX and FX has enhancing effects on innate immunity selectively and decreasing effects on delayed-type hypersensitivity of cell-mediated immunity according to medicinal part and diluted condition. This immunomodulating effects of HX, RX and FX might be responsible for the treatment of immune-mediated disorders.

Xanthii fructus which is well known as "Chang-ihjah" in Korea is the dried fruit of Xanthium strumarium L. (or Xanthium sibiricum PATR. Ex WIDD., Asteraceae. XS). Water extract of this fruit has been used for treatment of various inflammatory diseases such as tympanitis, allergic rhinitis, or ozena as alternative therapy material usually by oral administration in far Eastern countries including Korea. In this study, the effect of XS extract (XS-E) or XS-30% acetone fraction layer (XS-30% AFL) on the differentiation of $CD4^+$ T cells isolated from NC/Nga mouse and the production of IL-17 was investigated. The experimental results showed that $100\;{\mu}g$/mL of XS-E could decrease the production of IL-17 by $CD4^+$ Th17 cells by 2 fold and only $20\;{\mu}g$/mL of XS-30% AFL could inhibit 3.5 fold. The amount of IL-17A and IL-22 mRNA determined by real-time PCR was decreased remarkably when XS-E or XS-30% AFL was treated on $CD4^+$ Th17 cells(p<0.01, p<0.001). The amount of IL-17A protein determined by ELISA was also decreased remarkably(p<0.05, p<0.001). To study the effect of XS-E or XS-30% AFL on the proliferation of Th17 cells, $CD4^+$ T cells of a NC/Nga mouse was firstly differentiated by rIL-6/TGF-$\beta$ and then stimulated by rIL-23. The control group of Th17 cells were doubled every each day, while those of XS-E or XS-30% AFL treated group were shown to be delayed remarkably by these extracts. In conclusion, XS can inhibit the differentiation of Th17 cells of NC/Nga mouse and the production of IL-17 successfully, which may be a beneficial result for the treatment of atopic skin dermatitis.
