The composition analysis and electron donating activity of 4 kinds of Korean wild sannamuls[Cacalia firma Komar. (CFK), Aster scaber Thunb. (AST), Ligularia fischeri (Ledeb.) Turcz. (LFT), Synurus palmatopinnatifidus (Makino) Kitam., SDN)] were investigated. The Korean edible mountainous vegetable was named a sannamul or chwinamul in Korea, generally. Most of them, the characterization of the each vegetable was reported, individually without comparative research. This study was compared the proximate compositions, mineral, dietary fiber and electron donating abilities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) of sannamuls. In the chemical analysis of sannamuls, CFK was shown higher value in ash (5.4±0.18%), crude fat (2.5 ±0.14%), carbohydrate (8.1±0.21%), potassium (475.45±0.34mg) and magnesium (64.70±0.48mg) than others. Each mineral of the 3 other samples was a similar value but phosphorus in LFT was contained 62.91±0.43%. The compositions of total dietary fiber of the samples were listed CFK LFT SDN AST and the RC50 Value on DPPH radicals, LFK CFT AST SDN. These results have susggest that CFK and LFT may be useful for a funtional material to food development.

To evaluate the availability of Cudrania tricuspidata Bureau as a natural source of antimicrobials, the antimicrobial activity of methanol extracts of harvested parts was investigated using the paper disc diffusion method. The extracts from leaves and root bark had broad antimicrobial activity against various bacteria, including Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Streptococcus mutans, Listeria monocytogenes, Enterobacter aerogenes, Enterococcus faecalis, Salmonella choleraesuis subsp. choleraesuis, Vibrio vulnificus, and Pseudomonas aeruginosa and inhibited Bacillus cereus, Staphylococcus aureus, and Listeria monocytogenes, agents of food poisoning especially well. The extract from ripe fruit had a very high antimicrobial activity against Staphylococcus aureus with a 20.2 mm of clear zone at 50 mg/mL sample concentration. These results indicated that Cudrania tricuspidata could be used as new source for developing natural antimicrobial agents.

Astragalus membranaceus has a long history of medicinal use in Chinese herbal medicine. It has been shown to have immunostimulant, tonic, antioxidant, antiperspirant, diuretic, anti-diabetic, expectorant properties, and a supplementary medicine during cancer therapy. In this study, we investigated the effect of anti-oxidation of Astragalus membranaceus root extract. The anti-oxidative activities of water, 80% methanol, and 100% methanol extracts from Astragalus membranaceus were analyzed by DPPH free radical scavenging activity, Superoxide dismutase-like activity, reducing power, and crude ash. The water extract demonstrated to be more effective than methanol extract for a DPPH radicals scavenging activities and reducing power. Superoxide dismutase-like activity showed higher efficiency in 80% methanol extract. Our results indicate that Astragalus membranaceus extracts could be used as a source of antioxidant ingredients in the food industry.
This study was performed to compare the effects of immuno-modulating activities of Rhodiola sachalinensis A. Bor. fractionized by consecutive solvent separation. The Cytotoxicity of all fractionized extracts on human kidney cell (HEK293) was lower than crude extracts. Generally, the butanol and chloroform extracts showed less cytotoxicity on about 10.07% and 9.67% than the crude extracts. For human immune B and T cell growth, chloroform fraction showed the highest cell growth compared to the control. The secretion of cytokines (IL-6, TNF-α) on human B and T cells were increased by adding chloroform extracts. Also, NK cell growth was significantly improved up to nearly 30% by adding the supernatant of B cell medium grown with the chloroform fraction. It was also found that chloroform fraction could yield higher nitric oxide production from macrophage than untreated control cells. Differentiation of HL-60 cells was increased up to 131.9% after treatment with chloroform fraction extracts, compared to the control. These results indicate that the chloroform fraction of R. sachalinensis have high immune activation activity than others fractions and the crude extracts, implying that this chloroform fractions could be used a new functional material.
본 연구는 국내 주요 포도 품종인 캠벨얼리(Campbell Early)를 이용하여 발효전 원료의 전처리방법(열처리, CM처리)이 포도주 품질에 미치는 영향을 파악하고자 수행되었다. 총산에 있어서 CM처리를 할 경우 대조구나 열처리구에 비해 포도주의 총산이 낮아지는 결과를 보였다. 총안토시아닌과 탄닌 함량에 있어서, 열처리한 후 발효시킨 포도주가 대조구에 비해 높은 함량을 보인반면 CM처리의 경우는 대조구나 열처리에 비해 낮아지는 결과를 보였다.
This study was performed to compare effect of immune activities of Rhodiola sachalinensis by various extraction process with different temperature and extraction solvents. Experiments were performed for investigate the immune activities on human B and T cell growth and secretion of their cytokines. Also, antibodies in serum were investigated in female ICR mouse by feeding the extracts of R. sachalinensis at doses of 40, 120 and 360 mg/kg orally for 15 days. The immune cell growth and secretion of cytokines (IL-6, TNF-α) on human B and T cells were increased by adding R. sachalinensis extracts compare to the control. Also, total serum IgG levels increased by feeding R. sachalinensis extracts. It can be conclude that optimum condition for efficient extraction of R. sachalinensis as functional material is slovent extraction process using water with ultrasonification at below 100℃ than typical process.
We investigated the ecological characteristics of reed populations growing in Korea and tried to select reed populations showing better growth patterns in waste landfill leachate. To examine the growth characteristics, 14 reed populations from various habitats were collected. Four reed populations were from inland reclaimed habitats, 4 reed populations from brackish or salt marsh habitats, and 6 reed populations from fresh water habitats. Total plant biomass after the treatment with landfill leachate showed that Daebudo and Nanjido reed populations had the higher biomass with 3755 g DW/pot and 3305 g DW/pot, respectively. Reed populations being sampled from the higher salinity and landfill habitats had relatively higher total biomass than that of other reed populations. Especially reed populations from landfill habitats showed higher biomass. Reed populations from Songjiho and Daebudo, which were believed to have tolerance to salt stress, also showed good growth patterns. Population from the fresh water habitats exhibited relatively lower tolerance to leachate treatment compared to others. From the results, we could conclude that reed populations from Nanjido and Daebudo with higher biomass and better salt tolerance were able to good candidates for purification of waste landfill leachate.
