This study investigated the whitening activity using seomaeyakssuk (Artemisia argyi H.) extract. Seomaeyakssuk was extracted from hot DW (AAD) and 70% ethanol (AAE). And confirmed safety through assessment of cytotoxicity. Also, whitening activities were measured through changes in the levels of extracellular melanin, melanin synthesis, cellular tyrosinase activity and transcription factor. The results confirmed that significant cytotoxicity does not appear in the concentration range of 50, 100, and 200 ㎍/㎖ of both extracts of this study. The production of extracellular melanin was slowed by AAD 45.0% and AAE 1.3% at 200 ㎍/㎖ concentration. Also, production of intracellular melanin was decreased AAD 37.2% and AAE 24.6%. In the case of intra cellular tyrosinase activity was reduced to AAD 49.2% and AAE 35.6% at 200 ㎍/㎖ concentration. The mRNA expression of tyrosinase, TRP-1 and TRP-2 significantly decreased by AAD 63.0%/AAE 58.0%, AAD 60.0%/AAE 56.0% and AAD 59.0%/AAE 53.0%, respectively, following the 200 ㎍/㎖ sample treatment when compared to the control. Both extracts showed efficient changes of production of whitening-related factor and transcription factor. But AAD was found to have a higher inhibitory effect than AAE. In other words, seomaeyakssuk was showed significant biological activities showing whitening without cytotoxicity. These results will be provided as fundamental data for further development of the new material of functional cosmetics to the results above.

The anti-amnesic effect of Artemisia argyi H against trimethyltin (TMT)-induced learning and memory impairment and its neuroprotective effect against $H_2O_2$-inducedoxidative stress were investigated. Cognitive behavior was examined by Y-maze and passive avoidance test for 4 weeks, which showed improved cognitive functions in mice treated with the extract. In vitro neuroprotective effects against $H_2O_2$-induced oxidative stress were examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromide and lactate dehydrogenase (LDH) assays. A. argyi H. extract showed protective effects against $H_2O_2$-induced neurotoxicity; moreover, LDH release into the medium was inhibited. Finally, high-performance liquid chromatography (HPLC) analysis showed that eupatilin and jaceosidin were the major phenolic compounds in A. argyi H. extract. These results suggest that A. argyi H. could be a good source of functional substances to prevent neurodegenerative diseases.

The arial parts of Artemisia argyi were extracted with methanol : water (70:30), and the concentrates was partitioned into EtOAc (ethyl acetate), n-BuOH (normal butanol), and H₂O (water) fractions. The repeated silica gel and ODS (octadecyl silica gel) column chromatographies for EtOAc and n-BuOH fractions led to isolation of four flavonoids without any ambiguity based on intensive interpretation of several spectroscopic data including nuclear magnetic resonance, and mass spectrometry. The chemical structure of the isolated compounds revealed to (2S)-naringenin (1), 3-methylkaempferol (2), 3,3'-dimethylquercetin (3), and 3,3',4'-trimethylquercetin (4). These four compounds were first isolated from A. argyi through this study. In this study, four compounds isolated from A. argyi showed an increase in glutathione mean and a decrease in glutathione heterogeneity so that the compounds uniformly raised the intracellular glutathione (GSH) level. Based on these results, it is considered that it can be used as a functional pharmacological material.

This study was carried out to investigate the quality characteristics of vinegars containing jaceosidin and eupatilin using Artemisia argyi H. ethanol extract (AEE). 10% malt extract (ME) and water extract of Artemisia argyi H. (AWE) were also prepared for vinegar production. Three kinds of materials were mixed in the same amount to prepare vinegar as follows; CO (ME, water, 18% edible ethanol), SE (ME, water, and AEE), SW (ME, AWE, and 18% edible ethanol) and SM (ME, AWE, AEE). All samples were fermented by Acetobacter pasteurianus A8 at $30^{\circ}C$ for 25 days and analyzed at 10, 15, 20 and 25 days. The pH decreased significantly during the fermentation. pH was lower in SE and SM than CO and SW. The acidity increased significantly during the fermentation, and was highest in SM (4.44%) at 25 days of fermentation. The concentration of acetic acid was higher than other organic acids for all vinegars. Jaceosidin and eupatilin were not detected in both CO and SW, but both were detected in the SE and SM. At 25 days of fermentation, jaceosidin and eupatilin concentrations in SE and SM were 6.49-6.88 mg/kg and 2.23-2.24 mg/kg, respectively. From these results, we confirmed that production of vinegar containing jaceosidin, eupatilin and phenolic compounds can be prepared by using Artemisia argyi H. edible ethanol extract.

This study was performed to determine the ethanol ratios (30%, 50%, 70%, and 90%) of extraction solvent of Seomaeyakssuk (Artemisia Argyi H.) prepared using different methods (drying at room temperature [D], aging at $60^{\circ}C$ for 7 days after drying [AD], and roasting for 30 min at $160^{\circ}C$ after drying [RD]). The extract yield of the D extracts was lower than that of the AD and RD extracts, but the ethanol concentration of extract solvent did not affect. The L, a, and b values of the D extracts were highest, whereas those of the AD extracts were lowest. No clear trend was observed in the ethanol ratios. The soluble solids, total phenol, total flavonoid, jaceosidin, and eupatilin contents of each extract varied significantly, with RD > AD > D. The soluble solids significantly increased by ethanol ratio of extraction solvent, but other phytochemicals contents of 50% and 70% ethanol extracts were higher than others without affecting the processing methods. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was highest (77.71%) in the 70% ethanol extract obtained from RD. 2,2-azinbis-(3-ethylbenzo-thiazoline-6-sulphonate(ABTS) radical scavenging activity was significantly higher in 30-70% ethanol extract than 90% ethanol extract from RD. The results suggest that the contents of active ingredients and radical scavenging activity of ethanol extracts from Seomaeyakssuk were highest in the RD extract using 50-70% ethanol.

This study was carried out to select chamazulene containing species and to know whether chamazulene content varies depend on individual plants within a population or not. Among five collected mugworts, chamazulene was detected only in Artemisia indica. Chamazulene content in the leaves was higher than that in stems at vegetative stage. Camazulene in inflorescence was not higher than that in leaves even at reproductive stage. Chamazulene was higher in the leaves of the upper part of the plant than those of the middle and lower of the plant at vegetative stage. Chamazulene contents of 50 individuals within a population were varied from 0.01% to 0.11% with mean of 0.045%. About 36 individuals, 72 percent of total individuals examined, had more than 0.03% of chamazulene. There was no difference in chamazulene contents between parents and their clones.
