Some Compositae plants are known to contain biologically active substances that are allelopathic to weeds species as well as antioxidant to foods. Aqueous extracts from leaves of 3 plant species, Cirsium japonica, Kalimeris yomena, and Lactuca saliva, were bioassayed against alfalfa (Medicago saliva) to determine their allelopathic effects. The extracts applied on filter paper in bioassay significantly inhibited root growth of alfalfa. Extracts of 20 g dry tissue $\textrm{L}^{-1}$ from Lactuca sativa showed the most inhibitory effect on alfalfa seedling growth and followed by Cirsium japonica and Kalimeris yomena. Oxidative stability by Rancimat method and antioxidant activity by TBA method for the ground samples were the greatest in Lactuca sativa although were less than that of a commonly used antioxidant, 1% ascorbic acid. Antioxidant activity of methanol extracts on storing meat was stably kept for 28days and was excellent compared to control. These results suggest that three Compositae plants have potent allelopathic and antioxidant effects, and that their activities differ, depending on plant species.

Thirty plants of the Compositae family were screened for inhibitory activity of angiotensin converting enzyme (ACE). Among them, Chrysanthemum boreale Makino and Ixeris dentate Nakai were selected for further investigation since they had the highest inhibitory activity. Crude water extracts of the flowers of Chrysanthemum boreale Makino and the roots of Ixeris dentate Nakai were prepared by heating at 95$^{\circ}C$ and 6$0^{\circ}C$ for 2 hr, respectively, followed by centrifugation at 8000$\times$ g far 30 min. Crude extracts were then filtered using YM-3 and YM-1 membranes. The ACE inhibitors were isolated using consecutive chromatographic methods including: Sephadex G-15, ion exchange, FPLC, and reverse phase HPLC. The inhibitors were identified to have molecular masses of 204 and 283 daltons, respectively, by mass spectrometry. These results demonstrate that crude extracts of Compositae plants may be useful as functional food ingredients with anti-hypertensive properties.

The investigation assessed the influence of Compositae plants consumption on the protein profile in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in Sprague-Dawley rats by injection of STZ (45 mg/kg body weight) into tail vein. The rats were randomly assigned to five groups: normal and STZ-control fed an AIN-93 diet, and groups whose diets were supplemented with 10% Compositae powder containing Artemisia iwayomogi (A. iwayomogi), Atractylodes lancea (A. lancea) or Taraxacum mongolicum (T. mongolicum). To observe the effects of Compositae plants in the animal model, the levels of protein in liver, kidney, lung, pancreas, and brain were determined after 4 weeks. The level of protein in kidney increased significantly in rats receiving the A. iwayomogi- and T. mongolicum-supplemented diet compared to the STZ-control group. The level of protein in lung was increased significantly in the A. iwayomogi-supplemented group. Blood glucose level correlated well with brain protein level but did not correlate with other protein levels. Also, blood glucose correlated inversely with kidney, lung and brain protein levels. It is suggested that supplementation with A. iwayomogi in diabetic rats leads elevates protein in kidney and lung.

Phytotoxicity, antioxidant activity, and cytotoxicity of the aqueous or methanol extracts from the young sprouts of the six Compositae medicinal plants were determined. Aqueous leachates at 40g dry tissue $L^{-1}$ (g $L^{-1}$) Cirsium japonicum and Aster yomena showed the highest inhibitory effect on alfalfa (Medicago sativa L.). Total phenolic content showed the highest amount in methanol extracts from Ixeris dentata, and followed by A. yomena, and Cephalonoplos segetum. Methanol extracts of C. segetum and I. dentata at 25${\mu}g$ m$L^{-1}$ exhibited the highest DPPH radical scavenging activity by 87.2, and 52.8%, respectively. By means of HPLC analysis, MeOH extracts of C. segetum had the highest amount of antioxidant chlorogenic acid. Based on MTT assay, the methanol extracts from Y. sonchifolia ($IC_{50}$ = 65.7${\mu}g$ $mL^{-1}$) showed the highest cytotoxicity against Calu-6. These results suggest that plant extracts had a dose-dependent biological potentials including phytotoxicity, antioxidant activity, and anticancer activity, and that their activities exhibited differently depending on plant species.

전남 순천지역 들판에서 채취한 수종의 국화과 식물의 항산화 능력을살펴보았다. Rancimat와 TBA 방법을 이용하여 국화과 식물 중 항산화 효과가 높게 나타난 서양민들레, 조뱅이, 쑥을 선발하였다. 유지 산화안정도에 대한 실험에서 BHT와 ascorbic acid가 각각 3.86과 2.43 AI(Antioxidative Index)를 나타냈고 한련초 잎이 1.51 AI를 나타냈다. 이것은 서양민들레 잎이 유지산화안정도에 높은 항산화 효과를 나타냄을 의미한다. 한편 건조된 분쇄물과 메탄올 추출물을 이용한 장기간의 산화 억제에 대한 TBA실험에서 저장 4주 째에 BHT, ascorbic acid가 각각 0.05와 0.09 TBARS치를 나타낸 반면, 서양민들레 잎은 0.12의 수치를 나타내 대조구 1.01 TBARS치 보다 월등히 낮은 수치를 보여 우수한 항산화 효과를 보였다. 이상의 결과로 서양민들레, 조뱅이, 쑥 등의 국화과 식물에서 비교적 높은 항산화 활성을 확인할 수 있었다. 특히 이 식물체들은 기존의 인공 항산화제에 대한 하나의 대체수단으로서 식물유래 천연 항산화제로의 개발 가능성 을 시사해 주었다.

The purpose of this study is on identifying real condition of naturalized plants in urban green space. For this, Chollabak-do region was selected for case study. The occurring frequency and distribution status was investigated by field survey. The area of green open space, level of management and passed years after construction etc, were analized to identify the influence on occurrence of naturalized plants. The result is as follows: 1. In 18 sites, 145 taxa as weed species including naturalized plants were occurred. Average No. of occurring taxa is 22.7. Two families of plants, Graminae and compositae charged the most part. Also the rate of naturalized plant among them is 29.7%. 2. Naturalized species showing high occurring rate are 14 taxa of compositae, 5 taxa of Gramineae, Leguminosae and 4 taxa of cruciferae. These plants of previous four somatic polymorphism among all the naturalized plants. 3. The taxa number of naturalized plants were reducedby intensive management. But the rate of naturalized plants in extensively managed area was relatively lower than intensively managed one. Naturalizd plants were widely distributed in most of urban green space with being cognitioned as whole weed. 4. In origin of naturalized plants, the taxa from north America were 16 and the taxa from Europe were 16. Therefore the rate originated from north America and Europe charged high part as 68.2%. The rate of Annual, Biennial and Perennial were each 78.7%, 21.3%. The alternative of management for control aganist disturbance by Annual & Biennial required. 5. Multi-relations analysis shows 0.81 which is the relatively high interralation between the number of emerged axa and that of naturalized ones. 6. The number of naturalized species has no relation to the lapse of years after construction of open-space. Especially it was identified that weed control in the beginning of construction is very important. On the other hand the relation between Ys and Xp was Ys=1.784Xp+4.646.

The region containing 18S rRNA gene, ITS 1 and part of the 5.8S rRNA gene of the Atractylodes japonica Koidz was amplified by PCR and the product cloned in a pBluescript SK II plasmid. DNA sequence of the cloned DNA was determined and submitted to the GenBank (accession number EU678363). Phylogenetic analysis of the ITS 1 DNA showed close similarity with the other plant species of the family Compositae. The extract of the plant materials of five different members of the family Compositae was analyzed by HPLC to detect atractylon. Extract of the A. japonica Koidz showed presence of significant amount of atractylon. However, noticeable amount of atractylon was not detected by the same analyses from the extracts of the other plants belonging to the family Compositae including Artemisia capillaris, Chrysantemum zawadskii, Eclipta prostrata or Taraxacum platycarpum.

본 연구는 9종의 국화과 식물을 대상으로, 생리적 특성 및 생화학적 물질을 관찰함으로써 내건성식물을 선발하였다. 크기와 생장이 균일한 식물체를 선발한 후, 단수처리를 통하여 건조 스트레스를 유발하였다. 내건성식물 선발을 위해 엽록소함량, 엽록소함량, 상대수분함수량, 상대수분손실량, 프롤린, 환원당을 단수일로부터 30일동안 관찰하였다. 식물 생존율은 단풍취, 벌개미취, 참취, 좁은잎구절초 순으로 높게 나타났고, 나머지 5종은 고사하였다. 내건성식물 선발을 위한 나머지 요인들은 높은 생존율을 얻은 식물종을 기준으로 판단되었다. 그러나 엽록소함량은 단풍취, 단양쑥부쟁이, 벌개미취 순으로 높은 값을 보여, 단풍취와 벌개미취를 제외하고는 생존율과 연관성을 갖지 않는다고 판단되었다. 반면에 상대수분함수량, 상대수분손실량, 프롤린, 환원당에서는 참취, 단풍취, 벌개미취 3종이 상대적으로 높은 내건성식물로 판단되었고, 생존율과도 비슷한 연관성을 나타내었다. 결론적으로 국화과 식물 9종 중 참취, 단풍취, 벌개미취 3종이 상대적으로 내건성이 높다고 판단되었다.

본 연구는 우리나라 전역에 자생하는 국화류3종 학슬, 희렴, 한련초를 대상으로 MeOH 80% 추출물 및 헥산, 클로로포름, 에틸아세테이트, 부탄올 및 물분획을 이용한 항균활성, 항산화 및 tyrosinase 저해활성효과에 대한 연구를 통해 기능성 화장품소재로서의 이용가능성을 확인하고자 하였다. 연구결과 항균활성의 경우 MeOH 80% 추출물에서는 한련초와 용매분획 중에서는 학슬의 헥산분획, 희렴의 클로로포름분획, 에틸아세테이트 분획, 한련초의 클로로포름분획을 중심으로 항균력을 나타내었다. 항산화 활성의 경우 3종 모두 용매분획 중 에틸아세테이트, 부탄올 분획에서 90%이상의 효과를 나타내었다. Tyrosinase 저해활성의 경우 희렴과 학슬의 에틸아세테이트 분획물에서 우수한 활성을 나타내었다. 이상의 국화류3종 MeOH 80%추출물 및 분획물에서 항산화 및 미백작용이 우수하므로 기능성화장품소재 개발 활용이 가능할 것으로 생각된다.
