This study evaluated the quality and antioxidant activities of pork patties after adding Cirsium nipponicum powder in a ratio of 0%, 1%, 2%, 3%, and 4%, and the potential of Cirsium nipponicum as a functional food. The moisture content increased with an increase in the Cirsium nipponicum powder content while the pH, cooking loss rate, diameter loss rate decreased. The L and b values decreased with increase in the Cirsium nipponicum powder content while the a value increased; this trend was observed before and after heating the patties. The hardness, chewiness, and gumminess increased with increase in the Cirsium nipponicum powder content. Consumer acceptability test revealed that the 2% Cirsium nipponicum powder group had a higher score than the other groups in respect to color, flavor, taste, texture, and overall acceptance. Notably, as the Cirsium nipponicum powder content increased, there was an increase in the antioxidant activities; increased total pheonlic, flavonoid, DPPH radical scavenging activity and ABTS radical scavenging activity. Based on the present study results, adding 2% of Cirsium nipponicum powder into pork patties achieved the best functionality and sensory qualities.

This study evaluate the antioxidant activity and quality characteristics of muffins prepared with the addition of Cirsium nipponicum powder in the ratio of 0, 2, 4, 6, and 8% and confirm the possibility of using Cirsium nipponicum as a functional food. As the proportion of Cirsium nipponicum powder increased, the specific gravity of the muffins increased while their height, specific volume, moisture content and pH decreased. The baking loss rate of the samples prepared with the addition of Cirsium nipponicum powder was higher than in the control group. The 'L' and 'b' values decreased with the increase in the Cirsium nipponicum powder content, while the 'a' value increased. The evaluation of texture showed that hardness, chewiness, and gumminess increased with an increase in the Cirsium nipponicum powder content. As per the results of the consumer acceptability test, the 4-6% Cirsium nipponicum powder group showed higher scores than the other groups in the characteristics of color, flavor, taste, and texture, and the 4% group secured the highest score for overall acceptance. Also, with the increasing addition of Cirsium nipponicum powder, the antioxidant activity levels increased, as indicated by the total phenolic content, DPPH, and ABTS radical scavenging activities and reducing power. Based on these study results, muffins prepared with the addition of 4% of Cirsium nipponicum powder showed the best functional and sensory qualities.

Patterns of morphological variation in Korean Cirsium were examined using numerical analysis, and the delimitation of taxa was evaluated. Principal components analysis of individuals of taxa using 61 morphological characters revealed the presence of two major groups. One group included C. lineare, C. vlassovianum, and C. setidens, the other contained C. pendulum, C. japonicum var. japonicum, C. japonicum var. spinosissimum, C. schantarense, C. nipponicum, and C. rhiniceros. Also, the result of cluster analysis recognized three sections, Onotrophe, Pseudo-eriolepis, and spanioptilon. Korean Cirsium was classified into three sections; C. japonicum var. japonicum, C. japonicum var. spinosissimum, C. schantarense, C. rhiniceros and C. nipponicum were belonged to sect. Onotrophe, C. setidens, C. vlassovianum and C. lineare were belonged to sect. Spanioptilon, and C. pendulum was belonged to sect. Pseudo-eriolepis. In conclusion, Korean Cirsium was classified into three sections, eight species, three varieties, and five forms.

Cirsium chanroenicum, Cirsium nipponicum, and Cirsium schantarense plants were collected from Changwon, Ulleungdo, and Dooryoon Mountain, respectively. Cirsium japonicum plants were also collected from various locations in Korea. Genomic DNA was prepared from the collected plants and used for amplification of the 18S rDNA, ITS1, 5.8S rDNA, ITS2, and part of 28S rDNA. The ITS1 and ITS2 sequences of the PCR products and from other Cirsium plants reported previously were aligned and compared. Cirsium chanroenicum, Cirsium nipponicum, and Cirsium setidens formed distinct branches on the neighbor-joining tree. Cirsium japonicum and Cirsium pendulum appeared to be close to one another, but Cirsium pendulum plants were clearly clustered in an independent clade. Cirsium shantarense was clustered with the other Cirsium japonicum plants. The most important characteristic that distinguished these two species was the direction of the flowers. All Cirsium japonicum flowers point upward, but Cirsium shantarense flowers point downward. Other than this feature, these two species are almost indistinguishable morphologically. Cirsium chanroenicum is indistinguishable morphologically from Cirsium setidens, but it still formed a distinct group on the neighbor-joining tree based on ITS sequences, suggesting that this species is worth considering as an independent species. Silymarin production of the collected plants was analyzed and appeared to be quite high, indicating that the ability to synthesize silymarin is common to all Cirsium plants analyzed so far.

Chromosome numbers and karyotypes in flowering plants have been considered to be prominent features in taxonomic and evolutionary context. Despite the increasing numbers of cytological studies in Asteraceae, karyotype analysis of Cirsium Mill. and Carddus L. in Korean population have not been performed carefully. In this study, the chromosome numbers and karyotype analysis of all eight species of the genus Cirsium Mill. and one species of Carddus L. were analyzed. While the chromosome number in Carduus crispus L. was diploid (2n = 2x = 18 or 18+2Bs) with x = 9 as the base chromosome number, all seven species of Cirsium were diploid with x = 17 except for Cirsium lineare (Thunb.) Sch. Bip. (x = 14). The chromosome number in C. pendulum Fisch. ex DC. presented 2n = 2x = 34 from two populations and C. lineare exhibited 2n = 2x = 28 from one population. Aneuploidy was occasionally found in C. japonicum Fisch. ex DC. var. spinossinum Kitam. (2n = 2x = 34, 35, 36), C. rhinoceros (H. $L{\acute{e}}v.$ & Vaniot) Nakai (2n = 2x = 32, 34), C. setidens (Dunn) Nakai (2n = 2x = 30, 31, 32) and C. vlassovianum Fisch. ex DC. (2n = 2x = 31, 32). While Cirsium japonicum Fisch. ex DC. var. japonicum possessed several B-chromosomes (2n = 2x = 34, 35, 36), polyploidy was only encountered in Cirsium nipponicum (Maxim.) Makino. (2n = 4x = 68) from two populations in Ulleung Island. The present cytological data might be contributed to the taxonomic and evolutionary studies in the genus Cirsium.

The study was carried out to identify the characteristics of leafy shapes, and to establish the cultural practices such as shading condition, fertilization method, and planting distance of Cirsium nipponicum. Leaf shapes in this plant consist of two kinds, lobation and non-lobation which has two spur type showing large and small spur. Protein band patterns showed that a new protein band in non-lobation with large spur was appeared at the 116.4kDa. For shading condition and fertilization method, number of stems in non-shading and organic matter treatment was higher than that of shading 55% with 3.7. Fresh leaf yield on non-shading and organic matter treatment was higher than that of other treatments. Growth characteristics of leaf number was increased in the $60\times30cm$ treatment, but was redeuced to some extent compared with $60\times45cm$. To increase the fresh leaf yield, the optimum planting distance was $30\times20cm$ with 4,100kg/10a.

The crude extract of Saussurea lappa displayed significant lethality to brine shrimp larvae. Investigation of the causative components by bioactivity-directed fractionation resulted in the isolation of three $C_17$-polyene alcohols. Based on various nmr spectral data, these compounds were identified as shikokiols which had been previously isolated from Cirsium nipponicum and/or Centaurea aegyptica. These $C_17$-polyene alcohols exhibited moderate cytotoxicities against the human tumor cell lines, A549, SK-OV-3, SK-MEL-2, XF498, and HCT15.
