The essential oil fraction of Chrysanthemum sibiricum Turcz. (Compositae) was analysed by means of TLC and GLC. Utilizing silicagel column chromatography, a blue-color compound was isolated, and purified by preparative TLC. The obtain compound had the same Rf-value on TLC and exactly same UV-visible and IR spectra with that of chamazulene isolated from Matricaria chamomilla L. The composition of the essential oil was also compared with those from flowers of Chrysanthemum indicum L. and Chrysanthemum morifolim Ramatuelia.

본 연구는 구절초 꽃 추출물이 기능성 화장품 소재로서의 개발 가능성을 관찰하기 위하여 항산화 활성과 피부세포에 대한 세포독성, 항염증, 멜라닌 생합성 억제능에 미치는 영향을 관찰하였다. 본 연구 결과 구절초 꽃 추출물에서 폴리페놀과 플라보노이드의 높은 함량과 뛰어난 DPPH radical 소거작용을 확인하였고, Raw 264.7세포와 B16F10세포에 대해 유의한 세포독성을 나타나지 않았으며, Raw 264.7세포에서 LPS에 의해 유도된 NO 생성을 유의하게 억제함으로써 항염증 효과를 확인하였다. 구절초 꽃 추출물이 B16F10세포에 ${\alpha}$-MSH로 멜라닌 생성을 유도한 후 멜라닌 생합성 억제능을 측정한 결과 멜라닌의 생성 증가를 농도 의존적으로 억제되는 것을 확인하였다. 이와 같은 결과로 보아 구절초 꽃 추출물은 세포에 대한 독성이 낮고, 높은 항산화 활성과 항염증, 미백효과를 가진 기능성 화장품소재로써의 활용 가능성이 있을 것으로 사료된다.

This research was undertaken to find the in vitro inflammatory action of the essenetial oil (CS-oil) extracted from Chrysanthemum sibiricum (Compositae) herbs. We investigated the effects of the CS-oil not only on the formation NO, $PGE_2$, and $TNF-{\alpha}$ but also on inducible nitric oxide synthase and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-induced murine macrophage RAW 264.7 cells. The data obtained were consistent with the modulation of iNOS enzyme expression. A similar fashion was also observed when LPS-induced $PGE_2$ release and COX-2 expression were tested. The significant inhibitory effects were shown in concentration-dependent manners. In addition, CS-oil also mildly but significantly reduced the formation of TNF-a. These findings support the application of CS-oil as an antiinflammatory essential oil.

GC-MS data on the volatile oil (CS-oil) of Chrysanthemum sibiricum herbs led to the identification of 2-methoxythioanisol, (+)-camphor, geraniol, citral, thymol, eugenol, ${\beta}-caryophyllene$ oxide, ${\beta}-caryophyllene$, ${\beta}-eudesmol$, juniper camphor together with an unknown substance using the mass spectral library and literature data. CS-oil exhibited significant cytotoxicities on HL-60 $(IC_{50}\;12.5\;{\mu}g/ml)$ cell and mild on HepG-2 cell $(IC_{50}\;102.4\;{\mu}g/ml)$, though the antioxidant ability was found not to be potent $(IC_{50}\;97.2\;{\mu}g/ml)$. However, the component eugenol showed potent antioxidant ability but mild cytotoxicity. Methyleugenol with no phenolic OH showed less potent cytotoxic and antioxidative properties than eugenol suggesting that phenolic OH plays an important role for the cytotoxic and antioxidant abilities. The oil-pretreatment prevented lipid peroxidation induced by bromobenzene in the rat. Therefore, it was demonstrated that CS-oil could be a cytotoxic agent with antioxidant properties.

A yellowish microneedles, $C_{28}$ H$_{32}$ $O_{14}$ ${\cdot}$ I$_{1}$/$_2$, H$_{2}$O, m.p.262-$4^{\circ}$ , [${\alpha}$$_{D}^{20}$= -71,$43^{\circ}$(C = 0.42, pyridine), its acetate m.p.123-5.deg., were obtained in 0.3% yield from the leaves of Chrysanthemum sibiricum F$_{ISCHER}$. This substance is insoluble in water and the usual organic solvents except pyridine and ethylene glycol and, is not decomposed by dilute mineral acids but undergoes decomposition on being boiled in 60% H$_{2}$SO$_{4}$ or 35% HCl, giving one moel each of acacetin, glucose and rhamnose. It was not hydrolysed with a rhamnodiastase preparation obtained from the seeds of Rhamnus koraiensis. After permethylation of it, the uncrystallized product was hydrolysed and apigenin-5,4'-dimethyl ehter, m.p.$262^{\circ}$ was obtained, indicating that the disaccharide residue is at the 7 position of acacetin. Partial hydrolysis of this acacetin-7-rhamnoglucoside in cyclohexanol with formic acid gave acacetin-7-glucoside, m.p.246.deg. and rutinose, identifying them with authentic specimen on a paper chromatography. It was thus identified as linarin(acacetin-7-rutinoside) by means of mixed fusion, of paper partition chromatography and of its derivatives. Zemplen and Bognar suggested that the glucosidic linkage of linarin is .betha. by means of synthesis of this substance. But there is no evidence whether it is hydrolysed by emulsin or maltase or not. Linarin itself was not hydrolysed by an emulsin existing in the seed of Apricot or a maltase, but acacetin-7-glucoside(tilianin) which obtained from linarin gave acacetin and glucose on hydrolysis with the same emulsin and accordingly the glucosidic linkages of linarin and tilianin are thus regarded as ${\beta}$.

Nitric oxide (NO) is a free radical synthesized from L-arginine by nitric oxide synthase (NOS). It is believed that NO is an important mediator in numerous physiological and inflammatory responses. Particularly, a large amount of NO released from the inducible nitric oxide synthase (iNOS) is mostly associated with inflammatory processes. Overproduction of NO in these processes including sepsis and autoimmune diseases can have deleterious consequences and pathophysiologic relevance. Therefore, for the discovery of new inhibitory agents against iNOS activity, we have evaluated about 100 kinds of natural products after partition into three layers (n-hexane, ethyl acetate and aqueous) from 100% methanol extracts to study inhibitory effects on iNOS activity induced by lipopolysaccharide (LPS) in RAW264.7 cells culture system. As a positive control, curcumin, which is known as an anti-tumor promoter, anti-inflammatory agent as an iNOS inhibitor, was used and showed the dose-dependent inhibitory effect $(IC_{50},\;2.5\;{\mu}g/ml)$. Among tested fractions, the n-hexane fraction of Cimicifuga heracleifolia $(IC_{50}:\;9.65\;{\mu}g/ml)$, Forsythiae fructus $(IC_{50}:\;6.36\;{\mu}g/ml)$, Saposhnikovia divaricata $(IC_{50}:\;5.92\;{\mu}g/ml)$, and the ethyl acetate fraction of Chrysanthemum sibiricum $(IC_{50}:\;2.56\;{\mu}g/ml)$, Gastrodia elata $(IC_{50}:\;3.46\;{\mu}g/ml)$, and the aqueous fraction of Dianthus chinensis $(IC_{50}:\;6.73\;{\mu}g/ml)$, Euonymus alatus $(IC_{50}:\;6.78\;{\mu}g/ml)$, Mechania urticifoloria $(IC_{50}:\;8.01\;{\mu}g/ml)$ showed strong inhibitory activity against LPS-stimulated iNOS. Especially, the ethyl acetate fraction of Chrysanthemum sibiricum $(IC_{50}:\;2.56\;{\mu}g/ml)$, which exhibited the strongest inhibition against iNOS, was fractionated with silica-gel column chromatography. These subfractions exhibited dose-dependent inhibition against iNOS activity in the range of $2.59-5.6\;{\mu}g/ml$ except for fraction No. 3, 4, 5, 6, 8, 9, and 16. Our study shows that Chrysanthemum sibiricum has the strongest inhibitory effect against iNOS activity and has similar effect to curcumin. Therefore, further studies for the identification of active principles from Chrysanthemum sibiricum and investigation for the mechanism of the inhibition of iNOS by active principles will be performed.
