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.

Chrysanthemum boreale M. (hereafter, C. boreale M.), a perennial flower, has been historically used as a natural medicine in Korea. With increasing concerns for health-improving foods, the demand for C. boreale M. has become higher than ever. Howevr, the amount of wild C. boreale M. collected from mountainous areas is not enough to cover all demands. The cultivation system and fertilization strategy are required to meet increasing demand on C. boreale M. with a good quality. We investigated the effects of nitrogen application on plant growth and effective components of C. boreale M. to suggest optimum rate of nitrogen fertilization. C. boreale M. was cultivated in a pot scale (1/2000a scale), and nitrogen applied with rate of 0(N0), 50(N50), 100(N100), 150(N150), 200(N200), and $250(N250)kg\;ha^{-1}$. Phosphate and potassium were applied at the same level ($P_2O_5-K_2O=80-80kg\;ha^{-1}$) in all treatments. Maximum yield achieved in 246 and $226kg\;ha^{-1}$ N treatment on the whole plant and the flower part, a valuable part as a herbal medicine, respectively. Proline was the most abundant amino acid in the flower of C boreal M. and the contents of amino acids increased with increasing nitrogen application rate in flower. Nitrogen recovery efficiency was high more than 41% in all nitrogen treatments and increased to 61.8% in nitrogen N100 treatment. From the nitrogen content, the high nitrogen uptake, the low residue of mineral N and the reasonably good apparent fertilizer recovery, it can be inferred that C. boreale M. made efficient use of the available nitrogen. In flower, contents of Cumambrin A. which is a sesquiterpene compound and has the effect of blood-pressure reduction, decreased with increasing nitrogen application. However, the amount of Cumambrin A in flower increased as nitrogen rate increased, because of increasing flower yield. Conclusively, nitrogen fertilization could increase yields and enhance quality. The optimum nitrogen application rate might be on the range of $225{\sim}250kg\;ha^{-1}$ in a mountainous soil.
