  • 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.

  • To investigate phytotoxic substances in Artemisia argyi, the donor plant, and their biological activities, seed germination and seedling growth of receptor plants such as Arundinella hirta, Echinochloa crus-galli, Rumex crispus and Lactuca sativa were examined at different concentrations of aqueous extracts of the donor plant. Germination of four receptor species was inhibited by the extracts, while seedling growth was decreased to a lesser degree than in the germintion test. Germination, seedling growth and dry weight growth of Achyranthes japonica grown in pot were proportionally inhibited by the extracts. Volatile substances emitted from A, argi plant caused slight inhibition in the germination and seedling growth of the receptor species. Essential oil of the plant extracted by Karlsruker's apparatus inhibited growth of microorganisms and callus growth of Pinellia ternata and Oryza sativa. The GC /MS method was employed for analysis and identification of allelochemicals from A. argyi leaves. Sixty-one chemical substances such as a-pinene, camphene, 1. 8-cineol, etc. were identified from essential oil of A. argyi. The results of this experiment on seed germination, seedling growth, microorganism culture and tissue culture indicated that naturally occurring chemical substances from A. argyi would be responsible for the growth inhibition of plants studied.

  • Somatic chromosome numbers for 20 taxa of Korean Artemisia L. were investigated for the purpose of classification. Somatic chromosome numbers of treated taxa were 2n = 16, 18, 34, 36, 50, 52, 54, and therefore their basic chromosome numbers were x = 8, 9, 10, 13, 17. The chromosome number of A. japonica var. angustissima is being reported for the first time in this study. The chromosome numbers of 13 taxa were the same as in previous reports; A. capillaris (2n = 18), A. japonica var. hallaisanensis (2n = 36), A. japonica subsp. littoricola (2n = 36), A. annua (2n = 18), A. carvifolia (2n = 18), A. fukudo (2n = 16), A. keiskeana (2n = 18), A. stolonifera (2n = 36), A. sylvatica(2n = 16), A. selengensis (2n = 36), A. montana (2n = 52), A. lancea (2n = 16), A. sieversiana (2n = 18); however, the chromosome numbers of 6 taxa were different; A. japonica var. japonica (2n = 18, 36 vs 2n = 36), A. sacrorum (2n = 18, 54 vs 2n = 54), A. rubripes (2n = 16, 34 vs 2n = 16), A. indica (2n = 34, 36 vs 2n = 34), A. codonocephala (2n = 18, 50, 54 vs 2n = 50), A. argyi (2n = 34, 36, 50 vs 2n =34). The somatic chromosome numbers of Korean Artemisia are thought to be good characteristics for classifying some taxa such as A. japonica var. japonica, A. sacrorum, A. codonocephala, A. argyi, A. montana, A. sylvatica.

  • 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 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.

  • 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.

  • 황해쑥(Artemisia argyi H.Lev. & Vaniot)은 우수한 항염증 활성을 지닌 것으로 다양하게 보고 되었다. 그러나, 대표적인 염증 질환 중 하나인 골관절염에 미치는 영향은 현재까지 알려져 있지 않다. 따라서, 본 연구에서는 염증 유발 연골 세포 및 골관절염 유발 동물 모델에 미치는 황해쑥 효과에 대해 조사하였다. 첫째, interleukin 1 beta를 투여한 관절 연골 세포에 황해쑥 물 추출물을 투여한 후 metalloporeinase (MMP) -3 및 MMP-13의 발현을 mRNA 및 단백질 수준에서 분석 하였다. 또한, 내측 반월상 연골의 불안정화에 의해 유도 된 골관절염 마우스 모델을 사용하여 황해쑥 물 추출물의 골관절염 억제 효과를 분석 하였다. 세포 실험에서, 본 황해쑥은 MMP-3와 MMP-13의 mRNA 및 단백질 발현을 유의하게 억제하였다. 또한. 황해쑥 물 추출물을 투여한 실험 동물의 관절 조직을 Safranin O 염색을 실시하여 분석한 결과 연골 하 골판 두께의 감소 및 활막 염증 개선 효과가 관찰 되었다. HPLC를 이용한 성분 분석 결과, 황해쑥 물 추출물은 항염증 및 항관절염 활성을 가진 jaceosidin과 eupatilin을 함유하는 것으로 나타났다. 본 연구결과로부터 황해쑥은 골관절염의 치료 또는 예방에 유망한 소재로 개발될 수 있음을 시사한다.

  • The effect of Artemisia argyi H. under liquid-state fermentation by Monascus purpureus (AAFM) on cognitive impairments has been studied in a mice model of diabetes-associated cognitive decline induced by streptozotocin (STZ). C57BL/6 mice (9 weeks of age, male) were separated into four groups: a normal control, STZ-induced diabetic mouse group (STZ group), Artemisia argyi H. (AA) 10 group (diabetic mouse+AA 10 mg/kg/day), AAFM 10 group (diabetic mouse+AAFM 10 mg/kg/day). Administration of AA and AAFM significantly improved glucose tolerance, as shown by the intraperitoneal glucose tolerance test (IPGTT), and ameliorated cognitive deficit, as shown by the behavioral tests including passive avoidance, Morris water maze, and Y-maze tests. After behavioral tests, the cholinergic system was examined by assessment of the acetylcholine (ACh) level and acetylcholinesterase (AChE) inhibitory activity, and the antioxidant system was also assessed by measuring malondialdehyde (MDA) and superoxide dismutase (SOD) levels in the brain and liver.

  • Artemisia, a plant widely used as traditional herbal medicine in many countries, has drawn attention of the researchers. And its extracts or compounds are known to have an efficacy of antioxidant, anti-diabete, anti-cancer, anti-inflammation and neuroprotection. Sumaeyaksuk is a variant of the Artemisia argyi and major constituents are eupatilin and jaceosidin. This study was performed to investigate the effects of the sumaeyaksuk aqueous extract on inflammatory response induced by lipopolysaccharide (LPS) in human hepatoma HepG2 cells. To examine the potential hepatoprotective properties of sumaeyaksuk extract, cell viability, as well as nitric oxide (NO), reactive oxygen species (ROS), macrophage colony-stimulating factor (M-CSF), interleukin-8 (IL-8) levels, alanine transaminase (ALT), and aspartate transaminase (AST) activities, were measured. Cytotoxic activity of extracts on HepG2 cells was measured by MTT assay. Sumaeyaksuk extract did not induce cytotoxicity at concentrations of $0{\sim}400{\mu}g/mL$. NO and ROS levels significantly decreased with increasing concentration of the extract. The secretion levels of M-CSF and IL-8 were suppressed by sumaeyaksuk extract in a dose-dependent manner. Moreover, ALT (75.4%) and AST (61.6%) levels significantly decreased in sumaeyaksuk extract-treated cells at $400{\mu}g/mL$. These results suggested that the sumaeyaksuk extract attenuates the LPS-induced hepatotoxicity resulting from regulation of inflammatory factors and could potentially be used as a hepatitis therapeutic agent.
