Aerial parts of Compositae plants were harvested from pastures and crop fields of Sunchon area at vegetative stage to determine their antioxidant activity. Among 13 species, three species Taraxacum officinate, Breea segeta, and Artemisia princeps were selected as potent plant materials. Through measurement by Rancimat and TBARS method, antioxidative effect was the greatest in Taraxacum officinate among plant species. Antioxidative index (AI) investigated by Rancimat showed Siegesbeckia glabrescensi was 1.51 while commonly-used antioxidants, BHT and ascorbic acid were 3.86 and 2.43, respectively. The highest TBARS value was also obtained from Taraxacum officinate(0.18) at 4 weeks after storage, indicating the plant had the strongest antioxidant activity during long time. Even though TBARS value (0.18) in Taraxacum officinate sample showed lower in all plants than two synthetic antioxidants(0.05-0.09), antioxidant activities of the plants were much higher than that of a control (1.01). The results suggest that the plants have antioxidant potential as an alternative natural antioxidant based on natural plant resources.

The unrecorded plant, Aster hispidus var. leptocladus (Compositae), was reported from Mt. Palgong-san, Daegu-si, Korea and was named as 'Gin-ssuk-bu-jaeng-i' after its slender leaves. It is distinguished from var. hispidus by having glabrous linear cauline leaves with acute apex, small heads and involucre, short pappus in disc florets. It had been considered as Japanese endemic plant especially adapted to serpentine area.

꽃차(Flower tea)는 최근 다양한 제품이 개발되고 소비가 확대되는 등 그 산업적 가치가 증대하고 있다. 꽃차의 향기 특성은 우렸을 때 나타나는 색깔 및 인체에서의 생리활성과 더불어 주요한 꽃차 품질결정 요소이다. 본 연구는 꽃차로의 이용이 활발한 국화과 식물 중 구절초(Dendranthema zawadskii var. latilobum), 국화(Chrysanthemum morifolium), 노랑색 및 주황색 마리골드(Tagetes erecta 'Yellow' and 'Orange'), 그리고 캐모마일(Matricaria chamomilla)의 향기 성분특성을 구명하기 위하여 제조된 꽃차를 headspace-solidphase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS)를 이용하여 분리, 동정하였다. 국화과 꽃차로부터 총 117종의 휘발성 성분이 확인되었는데, 각 꽃차 종류별 동정된 휘발성 성분의 개수, 주요 3개 휘발성 성분과 전체 향기성분 peak중 이들이 차지하는 구성비율(%)은 다음과 같았다: 구절초 64종, camphor (31%), α-pinene(14%), camphene(14%); 국화 60종, camphor(15%), chrysantheny acetate(13%), eucalyptol (11%); 마리골드 '옐로우' 53종, 2,4-heptadienal(26%), trans-isocarveol(21%), cis-β-Copaene(18%); 마리골드 '오렌지' 61종, β-caryophyllene(16%), β-ocimene epoxide(12%), β-ocimene(12%); 캐모마일 50종, β-farnesene(63%), nonane(9%), spathulenol(5%). 국화과 꽃차 5종 모두에서 공통적으로 검출된 성분은 β-caryophyllene, α-pinene, β-farnesene 등 10종이었으며 마리골리 '옐로'는 '오렌지'와 주요 향기성분의 조성에서 뚜렷한 차이를 나타내었다. 비록 그 함량은 낮았으나 구절초, 국화, 마리골드 '오렌지', 그리고 캐모마일은 각각 10종, 12종, 3종 및 13종이었다. 마리골드 '엘로'의 경우 검출된 모든 향기성분은 마리골드 '오렌지'나 다른 국화과 식물의 꽃차에서도 검출된 바, 향기 성분이 다양성이 다소 낮게 나타났다.

This study was attempted to know the effect of crude extracts of Allium fistulosum on the seed germination and seedling growth in compositae. The result is as follows; The seed germination and seedling growth in the tested compositae were inhibited by the crude extracts from leaf blade, leaf sheath and root of Allium fistulosum. Generally the crude extracts from leaf blade part showed the highest inhibitory effect in the tested parts. The seed germination was inhibited by the crude extracts of Allium fistulosum extracted with 80% methyl alcohol and distilled water. But the crude extracts which had extracted with distilled water indicated more inhibitory effect than that of 80% methyl alcohol. The seedling growth was depressed by the root residues of Allium fistulosum in the soil after harvesting. The crude extracts had the character of stability in light and heat. Some out of the inhibitors contained the volatile substances.

This study was selected drought tolerant plants, by observing the physiological characteristics and biochemical materials from the 9 kinds of the Compositae plants. After selecting plants of the similar size, and then drought stress was induced by the irrigation stopping. Survival rates, chlorophyll values, relative water content(RWC), excised-leaf water loss(ELWL), proline, reducing sugar were measured after 30 days of stopping irrigation. The species that had high rates of survival were Ainsliaea acerifolia Sch. Bip, Aster koraiensis, Aster scaber, Dendranthema zawadskii(S), however other 5 species were dead. The remaining factors have been determined based on plant species showed a higher survival rate. However, chlorophyll content showed high values in A. acerifolia, A.altaicus var. uchiyamae, A. koraiensis, and will have been determined that has no correlation with survival rates, except for A. acerifolia and A. koraiensis. On the other hand, A. scaber, A. acerifolia, A. koraiensis were determined to be relatively high drought tolerant plants in RWC, ELWL, proline, reducing sugar, it showed a similar correlation with survival rate. As a result of 9 kinds of the Compositae plants A. scaber, A. acerifolia, A. koraiensis were considered relatively higher drought tolerant plants.

Saussurea nipponica subsp. higomontana was recorded first from Mt. Mudeung-san, Gwangju-si, Korea. We named the plant Mu-deung-chui. It had been considered as an endemic plant to Japan. S. nipponica sensu lato is the one of the most famous polymorphic species which consists of 7 infraspecific taxa (subspecies) isolating geographically. Among them, S. nipponica subsp. higomontana is distributed on high mountain regions of Kyushu and Shikoku.

천연자원으로부터 얻어진 항암 또는 세포독성물질로는 주로 alkaloid, lignan, terpenoid, macrolide 등에 속하는 물질들이고 그 중 sesquiterpene lactone계열 화합물에서 세포독성 및 항종양 활성이 있는 물질이 다수 얻어졌으며 그 대부분은 국화과의 식물에서 분리 보고되고 있다. Achillea 속 식물은 국화과에 속하는 다년생초본으로 남한에는 톱풀과 산톱풀 2종만이 자생한다. screening 결과 이 두 식물에는 segquiterpene lactone 화합물과 Peroxide등 다수의 활성성분이 함유되어 있을 것으로 기대되어 본 연구에 착수하였다. 두 식물의 각 분획에 대하여 SNU-1(위암세포주)과 SNU-354(간암세포주)를 이용해 검색한 결과 두 식물 모두 MC ext.와 MeOH ext.에서 현저한 세포독성을 보였으며 현재 MC ext. 로부터 세포독성물질의 분리를 수행하고 있다. EtOAc ext.는 세포독성은 거의 나타내지 않았으나 flavonoid 성분이 다수 존재함을 확인하였으며 면역활성 및 enzyme inhibition등의 활성을 검토하고자 화합물을 분리하였다. 그 결과 톱풀로 부터는 luteolin-7-0-glucoside와 apigenin-7-0-glucoside를 그리고 산톱풀로부터는 luteolin-7-0-glucoside, apigenin-7-0-glucoside, luteolin, apigenin을 분리 확인 동정하였다.
