  • Objectives: This study was camed out to examine the effect of five fractions of aqueous extract from Artemisia capillaris THUNB(ACT), on TGF, 1-induced apoptosis, cell viability, cell cycle progression and mRNA expression of apoptosis-related genes in human hepatocyte cell line HepG2. Methods: This study employed Tryphan blue exclusion assay, DNA fragmentation assay, Cpp32 protease activity assay and Quantitative RT-PCR analysis. Results: In the Tryphan blue exclusion assay, the butanol fraction of ACT with $TGF{\beta}$, l showed magnificent (Nice word, ut is it appropriate in a medical abstract\ulcorner) viability and the H2O fraction of ACT with $TGF{\beta}$, l also showed higher viability than only $TGF{\beta}$, l-treated group. DNA fragmentation assay showed that the butanol fraction and the H2O fraction carried inhibitory effects on apoptosis induction, with the butanol fraction displaying greater effects. The Cpp32 protease activity assay showed that the butanol fraction decreased Cpp32 protease activity. The H2O fraction of ACT had no significant effect on the Cpp32 protease activity. Quantitative RT-PCR showed that the butanol fraction suppressed Bax, p 15/INK4B, p21/Waf1, PAI-1 and increased Bcl-2 gene. Conclusions: The data shows that butanol fraction of ACT increases the hepatocyte viability and has the hepatocellular protective effect by the suppression of $TGF{\beta}$, l induced-apoptosis through gene regulation.

  • The antioxidant activity of Artemisia iwayomogi was determined by measuring the radical scavenging effect on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical. The methanol extract of A. iwayomogi showed strong antioxidant activity, and thus fractionated with several solvents. The antioxidant activity potential of the individual fraction was in the order of ethyl acetate > n-butanol > water > chloroform > n-hexane fraction. The ethyl acetate and n-butanol soluble fractions exhibiting strong antioxidant activity were further purified by repeated sitica get and Sephadex LH-20 column chromatography. Antioxidant chlorogenic acid was isolated as one of the active principles from the n-butanol fraction, together with the inactive components, 1octacosanol, scopoletin, scopolin, apigenin $7, 4^{I}$-di-O-methylether, luteolin $6, 3^{I}$-di-O-methylether (jaceosidin), apigenin methylether (genkwanin), 2, 4-dihydroxy-6-methoxyacetophenone $4-O-{\beta}-$D-glucopyranoside and quebrachitol. The antioxidant activity of chlorogenic acid was comparable to that of L-ascorbic acid, which is a well known antioxidant.

  • Artemisia apiacea is a traditional herbal medicine using treatment of eczema and jaundice in Eastern Asia including China, Korea, and Japan. In this study, the three phytosterol constituents were isolated and identified from the hexane fraction of 80% aqueous methanol extract of A. apiacea. Compounds were isolated using open column chromatography (silica gel). Their chemical structures were also established using $^1H$-NMR and $^{13}C$-NMR. Moreover, neuroprotective activity of each compound against glutamate-induced neurotoxicity in hippocampal HT-22 cell line was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Furthermore, Inhibition of reactive oxygen species (ROS) and calcium ion ($Ca^{2+}$) accumulation were measured for elucidation of neuroprotective mechanism of isolated compounds. They showed that stigmasterol had neuroprotective activity against the glutamate-induced toxicity by inhibition of ROS and $Ca^{2+}$ production. In conclusion, isolated compound of A. apiacea might be useful for therapeutic agent against neurodegenerative diseases.

  • 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.

  • In this study, we examined the hepatocyte toxicity and protective effects of an extract of Hericium erinacium cultivated with Artemisia capillaris (HEAC), and also examined the hepatocyte protective and antioxidative effects of a mixture of the HEAC and black garlic. At a concentrations of more than 0.05 mg/mL, the HEAC extract significantly reduced cell viability. The extract of HEAC treated with the same ratio of water and ethanol at $80^{\circ}C$ showed the highest hepatocyte protective effect. No significant difference in the hepatocyte protective effect was observed between the mixtures of HEAC with and without black garlic. In addition, higher antioxidative activity was shown with the addition of less black garlic. As a result of the sensory evaluation, a significant difference of sweetness was observed with varying liquid fructose concentration, but there were no significant differences in bitterness, flavor, thickness and overall acceptability according to the liquid fructose concentration.

  • This study investigated whether Ganoderma lucidum (Y2)-mediated fermentation of Artemisia capillaris extract (ACE) could synergistically enhance its antioxidant, anti-inflammatory, and tyrosinase-inhibiting activities. Both G. lucidum extract and fermented ACE exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging ability, but with poorer efficacy than ACE (even at a low ACE concentration). Viability of RAW264.7 macrophages was significantly reduced in the presence of ACE (150 mg/mL and above). However, this effect was greatly mitigated upon G. lucidum-mediated ACE fermentation. Additionally, relative to the same concentration ($25{\mu}g/mL$) of G. lucidum mycelial extract, ACE exhibited an improved ability to significantly inhibit RAW264.7 macrophage nitric oxide (NO) production. Finally, relative to the same concentration ($200{\mu}g/mL$) of a positive control (arbutin), fermented ACE exhibited an approximately 3.66 times higher capacity for tyrosinase inhibition. These results suggest that G. lucidum-fermented ACE possesses enhanced tyrosinase-inhibiting activity and may be of utility as a skin-lightening agent.

  • Portal hypertensive gastropathy (PHG) is part of a complex syndrome which occurs as a complication of chronic liver disease and portal hypertension. The gastric mucosa in these patients shows typical congestion of ‘mosaic-like’ pattern and vulnerable to various noxious agents such as NSAIDs and ethanol. We previously reported that DA-9601, a quality-controlled extract from Artemisia asiatica, exhibits cytoprotection against various gastritis models. In the present study we investigated the effect of DA-9601 on ethanol-induced gastric damage in PHG rats. Experimental PHG was produced by CBD ligation in SD rats. DA-9601 was orally administered at a dose of 30 mg/kg or 100 mg/kg daily for 2 weeks.

  • The dose-response effect of polysaccharide extracts(PS-1) from Artemisia iwayomogi was inves-tigated under various hepatic disease models. Silymarin, DDB and UDCA were used as reference compounds. We found that the maximal effective dose of PS-1 was 100 mg/kg b.wt. in $CCl_4$-induced hepatotoxicity, D-galactosamine-induced hepatitis, in ANIT-induced cholestasis and 300 mg/kg b.wt. in $CCl_4$-induced chronic liver disease, 30 mg/tg b.wt. in chronic bile duct ligation and chronic ethanol fatty liver. These findings suggest that PS-1 fraction protects the hepatocyte against various hepatic injuries, and this fracton might be of therapeutic value.

  • The purpose of this study was to investigate the dyeing properties of mugwort extract by nano-cellulose(n-cell). When dyeing cotton, rayon(artificial silk, called Ingyeon) and silk with mugwort extract, the difference with and without 2 wt% n-cell which it diluted to 0.6% treatment was compared. It was found that the addition of n-cell changed the values of L, -a(+red ~ -green), and b(+yellow ~ -blue) of all scoured cotton, rayon and silk fabrics, compared to dyeing only mugwort extract. Furthermore, it was confirmed that the ΔE and the K/S value slightly increased in all of the dyed cotton, rayon, and silk fabrics treated with n-cell at the same time as dyeing compared to the untreated ones. Therefore, by treating the fabric with n-cell, a natural cellulose component, at the same time as dyeing, it is expected to maintain stable fastness, which is a disadvantage of dyeing using natural dyes, and contribute to the utilization and commercialization of other natural dyes.

  • Artemisia princeps Pampanini (AP) has been used as a traditional medicine in Korea, China and Japan and reported to exhibit various beneficial biological effects including anti-inflammatory, antioxidant, anti-atherogenic and lipid lowering activities; however, its antiplatelet and anticoagulant properties have not been studied. In the present study, we evaluated the effects of an ethanol extract of Artemisia princeps Pampanini (EAP) and its major flavonoids, eupatilin and jaceosidin, on platelet aggregation and coagulation. To determine the antiplatelet activity, arachidonic acid (AA)-, collagen- and ADP (adenosine diphosphate)-induced platelet aggregation were examined along with serotonin and thromboxane A2 ($TXA_2$) generation in vitro. The anticoagulant activity was determined by monitoring the activated partial thromboplastin time (aPTT) and prothrombin time (PT) in vitro. The data showed that EAP and its major flavonoids, eupatilin and jaceosidin, significantly reduced AA-induced platelet aggregation and the generation of serotonin and $TXA_2$, although no significant change in platelet aggregation induced by collagen and ADP was observed. Moreover, EAP significantly prolonged the PT and aPTT. The PT and/or aPTT were significantly increased in the presence of eupatilin and jaceosidin. Thus, these results suggest that EAP may have the potential to prevent or improve thrombosis by inhibiting platelet activation and blood coagulation.
