The stability of carotenoid pigments extracted from Chrysanthemum petals against pH, sugar, and organic acid was investigated. The contents of total carotenoids in C. boreale and C. morifolium were 3.37mg% and 4.56mg% Per fresh weight, respectively. The elect of pH on the stability of extracted carotenoids showed that the periods reaching 50% of pigment retention were more than 5 to 6 days in pH 4, and the longer periods in pH 6 to 7 in both samples. The addition of sugars such as sucrose, sorbitol, glucose and fructose resulted in the reduction in pigment stability of C. boreale, but C. morifolium was contrast to C. boreale. However, citric acid and ascorbic acid were found to have a protective effect on both carotenoid samples extracted from C. boreale and C. morifolium.

To examine the allelopathic potentials of Chrysanthemum boreale, aqueous extracts and essential oil of the plant were used in these experiments. Seed germination of the receptor species was inhibited by the aqueous extracts and the inhibitory effect was increased in proportion to the concentration of extracts. In contrast, seedling elongation showed varied results. Achyranthes japonica, Bidens bipinnata, Raphanus sativus var. hortensis for. acanthiformis, Plantago asiatica, Pimpinella brachycarpa and Lactuca sativa were inhibited by increasing concentration of the aqueous extract, while Brassica campestris subsp. napus var. pekinensis and Echinochloa crus-galli were stimulated by the extract. Dry weight was also inhibited proportionally by increasing concentration of the aqueous extract, while some species were stimulated by a lower concentration of the extract. The volatile substances of C. boreale did not affect the seed germination of receptor plants, but seedling elongation and dry weight of some species were inhibited dose-dependently. Root hair development of selected plants was inhibited along with the concentration of essential oil. The above mentioned results, therefore, confirmed that the natural substances from C. boreale had allelopathic potentials to other plants.

Chrysanthemum boreale Makino (C. boreale) is widely distributed in Asian countries, and has traditionally been used to treat various inflammatory diseases including bronchitis. In this study, we aimed to isolate biologically active compounds from leaves and stems of C. boreale. Chemical components were purified by column chromatograpy and recyclic HPLC, and characterized from their spectral data (IR, MS, NMR). Biological activity experiments were conducted for Farnesyl-protein transferase (FPTase) activity, apoptosis and nitirc oxide (NO) release. As a results, three sesquiterpene lactones were isolated. Compound 1 (4-methoxy-8-O-acetyl-10-hydroxy-2,11(13)-guaiadiene-12,6-olide) showed strong cytotoxic activities having an average growth inhibition of 50% ($GI_{50}$) value of $1.89{\mu}g/m{\ell}$ against human colon adenocarcinoma cells. Compound 1 also showed a low half maximal inhibitory concentration ($IC_{50}$) value of $10{\mu}g/m{\ell}$ for NO release. In the caspase 3 activity, compound 1 and compound 2 (8-O-(2-carbonyl-2-butyl)-3,10-dihydroxy-4,11(13) -guaiadiene-12,6-olide) exhibited 94% and 90% apoptosis inhibition activity, respectively. Compound 3 (4,8-O-diacetyl -10-hydroxy-2(3),11(13)-guaiadiene-12,6-olide) showed a strong inhibitory effect on FPTase activity with 90% inhibitory activity at a concentration of $100{\mu}g/m{\ell}$. These results clearly show the presence of lactone compounds in the leaves and stems, which may partially contribute to the pharmacological activity of C. boreale.

산국(Chrysanthemum boreale M.)은 국화과에 속하는 다년생 식물이며 우리나라에 널리 분포하는 자생식물자원으로서 오래 전부터 식용과 약용으로 널리 이용되어 왔다. 최근 건강에 대한 관심이 고조되면서 산국의 수요가 급증하고 있으나 자연채집을 위주로 하기 때문에 공급을 충당하지 못하고 있는 실정이다. 본 연구에서는 우수품질의 산국을 대량생산하기 위해 질소시비반응 시험을 실시하였다. 처리구는 질소수준에 따라 6처리구(0, 50, 100, 150, 200, $250kg\;ha^{-1}$)로 설정하였다. 이때 모든 처리구에서 기본적으로 $P_2O_5-K_2O=80-80kg\;ha^{-1}$을 시비하였다. 그 결과, 질소의 시비량이 증가할수록 수량이 증가하였다. 전체 산국을 건물중으로 하여 회귀곡선을 통해 추정한 결과 N $246kg\;ha^{-1}$였으며, 꽃의 수량은 N $226kg\;ha^{-1}$이였다. 꽃의 주요 아미노산은 proline이였고 질소의 시비량이 증가할수록 아미노산의 함량이 증가하였다. 이때 질소의 이용율은 41.5-61.8%였고 N100처리구에서 가장 높았다. Sespuiterpene계 화합물로서 우수한 혈압강하효과를 가지고 있는 물질인 Cumambrin A의 함량은 식물부위 중 꽃에 가장 많이 함유되어 있었다. 질소의 시비량이 증가할수록 Cumambrin A의 함량이 다소 감소하였으나 통계적 유의성은 인정되지 않았다. 꽃에서 Cumambrin A의 전체 함량은 산국의 수량증가에 따라 질소 시비량이 증가할수록 증가하는 경향을 보였다. 따라서 유효성분이 많이 함유된 양질의 산국재배를 위해 질소의 적정시비량은 $225{\sim}250kg\;ha^{-1}$ 수준으로 판단되었으며 포장시험을 통한 현장입증시험이 있어야 할 것으로 판단된다.
