To investigate the antitumor activity of mugwort (Artemisia princeps Pampan), petroleum ether extract of mugwork was partially purified by a silica gel chromatography. Among several fractions, the fraction which was obtained under the elution with acetone, showed potent cytotoxicity against mouse leukemia cell line(Ll210), human colon cancer cell line (HCT-48) and human hepatoma cell line (Hep G2) , but was less effective with normal cell line(mouse embryo cell). Acetone fraction appeared to be glycolipid by Benedict test and the major fatty acids of the lipid were C16 ; 0 , C 18: 3by GC/MS analysis.

This study was devised to observe the antitumor activity of mugwort (Artemisia princeps Pampan.) against ICR mice inoculated with sarcoma-180 cells. The antitumor compounds were partially purified from petroleum ether extract of mugwort by silicic acid column chromatography. The active fraction used in in vivo test was obtained under the elution with acetone in silicic acid column chromatography. When the acetone fraction was intraperitoneally injected to the mice which had been subcutaneously inoculated on the left groin with sarcoma-180, the growth rate of tumor (sarcoma-180 mass) was inhibited by 30%. In case the acetone fraction was injected to the mice which had been inoculated intraperitoneally with sarcoma-180, the average life span was prolonged by 20%. After the injection of the active fraction, the spleen index and ${\gamma}-globulin$ ratio (%) were increased significantly (p<0.05). The administration of acetone fraction did not cause any abnormality in the body and the homeostasis of mice. Those observations suggest that the acetone fraction of mugwort extract has an antitumor effect in vivo.

This study investigated the chemical composition of Artemisia princeps var. orientalis (Pampan) Hara (ssuk in Korea) essential oil and the quantitative changes of major terpene compounds according to the time of harvest. The essential oils obtained by hydrodistillation extraction from the aerial parts of ssuk were analyzed by GC and GC-MS. The essential oil composition of ssuk was characterized by higher contents of mono- and sesqui- terpene compounds. Ninety-nine volatile flavor compounds were identified in the essential oil from ssuk harvested in 2010, with camphor (11.9%), ${\beta}-caryophyllene$ (9.11%), dehydrocarveol (8.51%), and borneol (7.72%) being the most abundant compounds. Eighty-three compounds were identified in the essential oil from the plant harvested in 2011, with borneol (12.36%), caryophyllene oxide (12.29%), ${\beta}-caryophyllene$ (10.24%), camphor (9.13%), and thujone (8.4%) being the most abundant compounds. Eighty-four compounds were identified in the essential oil from the plant harvested in 2012, with ${\beta}-caryophyllene$ (20.25%), caryophyllene oxide (14.63%), and thujone (11.55%) being the major compounds. Eighty-nine compounds were identified in the essential oil from the plant harvested in 2013, with thujone (23.11%), alloaromadendrene oxide (12.3%), and ${\beta}-caryophyllene$ (11.48%) being the most abundant compounds. Thujone and aromadendrene oxide contents increased significantly from 2010 to 2013, while camphor and dehydrocarveol contents decreased significantly during those 4 years. The quantitative changes in these 4 compounds according to the time of harvest can served as a quality index for ssuk essential oil. The ecological responses to recent climate changes may be reflected in the chemical components of natural plant essential oils.

In this study, we identified the volatile compounds of Artemisia princeps Pampan. cv. ssajuari (ssajuarissuk) essential oils and analyzed changes in the contents of volatile compounds under four different storage conditions, such as exposure to air at $20^{\circ}C$ and $40^{\circ}C$. Sixty-five volatile compounds consisting of 6 monoterpene hydrocarbons, 23 oxygenated monoterpenes, 16 sesquiterpene hydrocarbons, 6 oxygenated sesquiterpenes, 1 diterpene, 6 benzene derivatives, and 7 non-isoprenoid compounds were identified on the basis of their mass spectra characteristics and retention indices from original ssajuarissuk essential oils. Identified compounds constituted 90.56% of the total peak area. Borneol (10.29%) was the most abundant compound in the original ssajuarissuk essential oils, followed by 1,8-cineole (9.06%), viridiflorol (8.99%), spathulenol (8.73%), $\alpha$-thujone (5.28%), and camphor (4.39%). After six months storage at $40^{\circ}C$ with the cap opened for 3 min everyday, the total amount of volatile compounds in essential oil as determined by the percentage peak area decreased by 84.93%. The total levels of cis-sabinene hydrate, camphor, 4-terpineol, humulene oxide, $\beta$-caryophyllene oxide, and caryophyllene alcohol increased significantly. For ssajuarissuk essential oils stored under experimental conditions, changes in the contents of volatile compounds in essential oils were accelerated by temperature and contact with the atmosphere.

Volatiles in Artemisia princeps Pampan. cv. sajabal (sajabalssuk) and A. princeps Pampan. (ssuk) treated with different processing were analyzed using headspace-solid phase microextraction (HS-SPME)/gas chromatography- a mass selective detector (GC-MS). Sajabalssuk and ssuk were treated with steam distillation (SD) and freeze-dried/steam distillation (FD/SD) while controls were raw sajabalssuk and raw ssuk. Sajabalssuk had significantly more total volatiles than ssuk in control and FD/SD treated samples (p<0.05). Major volatiles in raw sajabalssuk were 2-hexenal, 1,8-cineol, trans-caryophyllene, and hexanal while those in raw ssuk were 1-hexanol, ${\beta}$-myrcene, limonene, and 2-hexenal, which implies that substantial lipid oxidation occurred in raw samples. Sajabalssuk with SD and FD/SD treatment had higher peak areas of 1,8-cineole, 4-terpineol, 1-octen-3-ol, and ${\alpha}$-terpineol while ssuk with SD and FD/SD treatment possessed 1,8-cineol, camphor, borneol, artemisia ketone, ${\alpha}$-thujone, and 1-octen-3-ol, which showed that steam distillation produced more volatiles from terpenoids than raw samples. Based on the results of HS-SPME/GC-MS, relative amounts of volatiles from lipid oxidation including 2-hexenal, hexanal, and 1-hexanol were reduced in sajabalssuk and ssuk with freeze-drying and/or steam distillation treatment.

Volatile profiles of beverages and encapsulated powders containing Artemisia princeps Pampan extracts were analyzed by solid-phase microextraction-gas chromatography/mass spectrometry during production and storage. Beverages containing 0.32 and 0.64% extracts were stored at room temperature for 8 weeks and $60^{\circ}C$ for 8 days, respectively. Encapsulated particles were stored at room temperature and $60^{\circ}C$ for 8 days. Total volatiles in beverages decreased significantly during storage, irrespective of storage condition (p<0.05). Terpenoids, including cymene, thujone, and ${\beta}$-myrcene, were major volatiles in beverages, and some volatiles including ethylfuran, vinylfuran, and 2-fufural increased in 60oC samples only. Total volatiles in microcapsules at room temperature were not significant different for 8 days (p>0.05), whereas those at $60^{\circ}C$ increased by 16.5 times. Limonene was the most detected volatile in microcapsules, and aldehydes such as hexanal, pentanal, and octanal, and furans such as 2-butylfuran and 2-pentylfuran increased in the $60^{\circ}C$ samples, which may have originated from oxidized lipids used in the microcapsules.

In activated macrophages the inducible form of nitric oxide synthase (i-NOS) generates high amounts of toxic mediator, nitric oxide (NO) which contributes to the circulatory failure associated with septic shock. A sesquiterpene lactone compound (yomogin) isolated from medicinal plant Artemisia princeps Pampan inhibited the production of NO in LPS-activated RAW 264.7 cells by suppressing i-NOS enzyme expression. Thus, yomogin may be a useful candidate for the development of new drugs to treat endotoxemia and inflammation accompanied by the overproduction of NO.

The extracts from natural and fermented products such as Artemisia plants, Rhodiola Salientness, fermented soybeans and soybean paste were used to investigate the whitening effect. 10 g of Artemisia plant were added to 300 mL of ethanol and extracted by sonification at room temperature for 3 h. The extract was further partitioned by the equal volume percent in the order of the n-hexane, chloroform and ethyl acetate. 5 g of Rhodiola salientness was also added to 150 mL of methanol and extracted at the room temperature for 12 h. The effluents from a chromatographic column ($3.9{\times}250mm$, $C_{18}$, $15{\mu}m$) were collected and concentrated in two parts. The extraction of fermented soybeans and soybean paste were done by 60% ethanol. In this work, tyrosinase inhibitory activity and melanin inhibitory effect were measured to confirm the whitening effect. The water layer of Artemisia princeps Pampan showed the good inhibitory of antioxidant, while the hexane layer of Artemisia iwayomogi Kitamura and the chloroform layer of Artemisia princeps Pampan had the excellent melanin inhibitory effect. The Rhodiola salientness had the superior whitening effect to the arbutin in in-vivo melanin production ratio assay. However, the fermented soybeans and soybean paste did not show any whitening effect.

The seasonal pattern and the annual magnitude of the internal (or biochemical) and plant-soil cycles of phophorus in adjacent three different herb plant populations-Helianthus tuberosus L., Artemisia princeps Pampan and Phalaris anundinacea L.-in an old field of the basin in the Mt. Geumoh were investigated. A lot of the phosphorus demand for the three populations was supplied by the withdrawal from below-ground organ in early growing period, by the absorption from soil in mid-growing period and by the withdrawal from stem in later growing period. But in the A. princeps and P. arundianacea populations, a great deal of phosphorus seemed to be absorbed prior to the first withdrawal. The annual amount of the phosphorus flowing throughthe internal cycle was about 59% of the total hosphorus flow on theorgan level in the H. tuberosus population, 41% in the A. princeps population and 32% in the P. arundinacea population, indicating that the tuber plant had the most developed internal cycle system. The annual amount of phosphorus which took part in the plant-soil cycle in the stand of the three populations was in the range of 4.49-5.65 gPm-2, corresponding to only 3-8% of the extractable phosphorus contained in the soil of 0-20 cm depth. The fact that the H. tuberosus population is higher in the extent fo internal cycle but smaller in the magnitude of plant-soil cycle and lower in the turnover rate of phsophorus than the other two populations suggests that the growth of H. tuberosus population may be less dependent on soil phosphorus availability than those of the other two populations.
