  • This study was carried out to investigate the fermentation characteristics and storage of set-type yoghurt added mugwort extracts(AME) such as pH, growth of lactic acid bacteria, number of viable cells, viscosity, and sensory characteristics during 24 hours fermentation and 15 days storage. Addition of mugwort extracts was grown rapidly of lactic acid bacteria rather than that of control and also 4 or 8% AME groups were grown similar to control. The drop of AME pH of broth was less compared with control during incubation of lactic acid bacteria. The growth of lactic acid bacteria during incubation of AME yoghurt was not different of viable cell count between AME group and control in beginning time, but the viable cell count of AME groups were increased depended opon addition quantity of AME in ending time. Addition of mugwort extracts was not affect on pH change during yoghurt fermentation and increased a lactic acid bacteria number as well as no effect of yoghurt fermentation in ending time. The viscosity of yoghurt was almost not changed 3 hours after yoghurt mix and increased rapidly 6 hours after yoghurt mix. Although control and 0.5% AME group showed maximum viscosity at 18 hours of fermentation, 1 and 2% AME group showed linear increase until 24 hours of fermentation. Mugwort did not affect pH and viable cel number of lactic acid bacteria during 15 days storage 24 hours after fermentation. Sensory evaluation of the AME yoghurt showed that flavour, texture and acid taste were not affected by addition of mugwort. However, the appearance and taste were dropped by addition of mugwort.

  • In this study, the effect of complex hot water extracts of Cirsium jaonicum, Artemisia annua and Curcuma longa (CAC) on the improvement of non-alcoholic fatty liver disease (NAFLD) was investigated. CAC inhibited fatty acid synthesis and lipid accumulation in HepG2 cells cultured with free fatty acid (FFA). In the NAFLD animal model, CAC extract suppressed the increase in body weight, liver, and epididymis fat weight, and suppressed the increase in hepatocyte fat and blood triglyceride. In addition, by blocking the Nrf2/HO-1 signaling pathway, cells were protected from oxidative stress in hepatocytes. Moreover, CAC inhibited the expression of COX-2, iNOS, TNF-α and IL-17 in hepatocytes. These results suggest the possibility that CAC extract can be applied in the field of health functional foods and pharmaceuticals for improvement and prevention of NAFLD.

  • Artemisia iwayomogi(A. iwayomogi) is a major edible vegetable in Korea. A iwayomogi containing a strong bitter taste, particularly, is known to manifest an effect on cough, abdominal pain, indigestion and bleeding. In this experiment, ethanol extract of A. iwayomogi(50mg/kg body weight) was fed to growing male Sprague-Dawley rats for four weeks in order to examine the lipid lowering effect of A. iwayomogi in the live and serum. High fat diet included 10% lard, 1% cholesterol and 0.25% sodium cholate. The administration of A. iwayomogi extract decreased serum cholesterol compared with the control. At the same time, serum triglyceride(TG) was decreased to 25%. Although atherogenic index and HTR tended to decrease, phospholipid level in the serum was shown to increase by A. iwayomogi administration. At the same token, total liver lipids were decreased to 40%. The group fed both high fat and ethanol extract showed 28% decrease of liver lipids compared with the group fed only high fat diet. On the other hand, HDL cholesteol level of high fat and extract fed group was increased to 30% compared with the non-extract-fed control. Liver TG also was decreased to about 21% in the extract fed groups. Liver phospholipids, particularly, exceeded more than double of the level of high fat control. The above results indicate than A. iwayomogi exert a strong hypocholesterolemic and hypolipidemic effect which may lead to the protection from hypertention, obesity, stroke and many other circulatory diseases.

  • To develop the health/functional food materials, we investigated the cultural condition of mycelial growth on the solid state fermentation using the brown rise, Acanthopanax sp. and Artemisia sp., and also evaluated inhibitory activity of angiotensin converting enzyme (ACE) of hot water extracts from cultured media of Pleurotus eryngii. As the amount of Acanthopanax nnd Artemisia In the cultural media increased, the mycelial growth rate decreased. Especially, addition of Aeantopanax showed marked effect than Artemisia. Moisture contents in three kinds of cultured media were in the range of $10.9{\sim}12.0%$. Crude protein fat and crude fiber content were the highest value in cultured brown rice medium, whereas the mineral contents (Ca, K and P) were higher in the Acanthopanax supplemented (5%) medium than the other media, The extraction yield of the Artemisia supplemented (5%) medium was the highest value of 4.80%, and the pH of hot water extract from cultured brown rice medium showed the lowest value of 6.1. Lightness (L) values in three kinds of extracts from cultured media were in the range of $85.8{\sim}87.1$. Redness (a) value was the highest In the brown rice and Acanthopanax supplemented media, however cultured Artemisia supplemented medium showed the highest value in yellowness (b). In comparison of sugar components analyzed by the thin layer chromatography with three kinds of samples, two spots were detected to be glucose and maltose, respectively. The ACE inhibitory activity of hot water extract from the cultured Acanthopanax supplemented medium showed the highest value at the concentration of $0.2{\sim}1.0\;mg/ml$. These results suggest that the Pleurotus eryngii grew in natural media using brown rice and Acanthopanax can be supplemented to the brown rice medium to enhance its ACE inhibitory activity as health/functional food materials.

  • The extract from Artemisia annuain L.(AAE) is known as a medicinal herb that is effective against cancer. Apoptosis is the process of programmed cell death, and mitochondria are known to play a central role in cell death control. In this study, we evaluated the p53-independent apoptosis of extract of AAE through downregulation of Bcl-2 and the mitochondrial pathway in A549 (lung cancer cells). AAE may exert cancer cell apoptosis through regulating p-Akt, Cox-2, p53 and mitochondria-mediated apoptotic proteins. p-Akt/cox-2 is known to play an important role in cell proliferation and cell survival. The Bcl-2 pro-apoptotic proteins (such as Bax, Bak and Bim) mediate the permeabilization of the mitochondrial outer membrane. Treatment of AAE reduces p-Akt, p-Mdm2, cox-2 and anti-apoptotic proteins (such as Bcl-2), while tumor suppressor p53 and pro-apoptotic proteins. Activation of Bax/Bak releases cytochrome c from mitochondria to the cytosol to activate a caspase. Caspase-3 is the major effector caspase associated with apoptotic pathways. Caspase-3 generally exists in cytoplasm in the form of a pro-enzyme. In the initiation stage of apoptosis, caspase-3 is activated by proteolytic cleavage and activated caspase-3 cleaves poly (ADP-ribose) polymerase (PARP). We treated Pifithrin-α (p53 inhibitor) and Celecoxib (Cox-2 inhibitor) to learn the relationship between the signal transduction of proteins associated with apoptosis. These results suggest that AAE induces apoptosis through a p53-independent pathway in A549.

  • Fatty acid is an important component of many biological processes. However, an imbalance in diet-especially, a n-3 polyunsaturated fatty acids (PUFAs) deficiency-causes several diseases such as diabetes, cardiovascular disease and cancer. In this study, we analyzed the fatty acid contents and compositions of 26 species of Korean salt marsh plants and found high fatty acid contents from S. herbacea ($148.75\;{\mu}g$/mg-dry wt.), S. komarvii ($119.05\;{\mu}g$/mg-dry wt.), C. heterocarpa ($79.23\;{\mu}g$/mg-dry wt.), A. capillaris ($71.65\;{\mu}g$/mg-dry wt.), and L. tetragonum ($67.02\;{\mu}g$/mg-dry wt.). In the case of saturated fatty acids (SFAs) composition, palmitic acid is richest in most salt marsh plants. On the other hand, oleic acid and linoleic acid are major components of monounsaturated fatty acid and n-6 PUFA, respectively. In addition, n-3 PUFAs such as LNA (linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid) known as the main fatty acid components of fish oils and seaweeds, were also found in S. herbacea, S. komarvii, T. tetragonoides, A. capillaris and G. littoralis.
