  • Ligularia fischeri is widely grown in Korea and is containing medicinal components such as chamomile, jacobine, and ameleme etc.. Its juices from the leaf are well known for anticancer effect. This study was conducted to make Ligularia fischeri as functional food resources as food produce. To examine quality characteristics of Ligularia fischeri - such as color, texture, fiber, minerals, tannin, crude proteins, crude lipids and sensory quality - were determined using physicochemical methods. The content of dietary fibers were 0.56 g in each 100 g of freeze dried Ligularia fischeri. One of the mineral contents, iron showed the highest value. The contents of tannin were 33.3 ppm in fresh Ligularia fischeri. As results of food products having Ligularia fischeri, the content of crude protein were about $9.35\%$ and $10.37\%$ in rolling snack and garlic bread respectively. The content of crude lipid were about $28.27\%$ and $23.39\%$ in rolling snack and garlic bread, respectively. In sensory evaluation, garlic bread appeared better preference than rolling snack, and older age group showed a better acceptability.

  • In this study, Bokbunja (Rubus coreanus), which has various medical applications and excellent functionality, was used together with Teriyaki sauce to compare and analyze the effect of different amounts of Bokbunja (0, 3, 6, 9, 12%) on the physico-chemical quality of a Teriyaki sauce. The sensual quality of Bokbunja Teriyaki sauce and a roasted eel spread with Bokbunja Teriyaki sauce was analyzed to detemine the merchandising potential of this sauce. The moisture content of the Teriyaki sauce decreased as the amount of added Bokbunja increased, and the 3% group showed the highest decrease, which was 73.1%. As the amount of added Bokbunja increased the pH was showen to decreased, and the sweetness of the Teriyaki sauce increased. The sauce containing 12% Bokbunja had the highest increase of $36.9^{\circ}Brix$. The amount reducing sugar was significantly different between each sample. In terms of the L (lightness) value, highter amounts of added Bokbunja resulted in an increase in the L (lightness) of the sauce and significant differences were obsered between sample groups. In regards to the texture, no significant changes were shown for hardness even though the amount of Bokbunja added was different. There was a significant difference between samples for gumminess, a highter concentration of Bokbunja resulted in a higher gumminess of the sauce. As for adhesiveness, there was a significant difference between samples; as more Bokbunja was added, the sauce became betwkier. In regards to the preference of roasted eel containing this sauce, the 6% Bokbunja sauce was the most preferred with a score 7.98 points, and as for flavor, there was significant difference between sauces containing 3, 6 and 9% Bokbunja. In addition there wasn't any significant difference between each sample for sweetness. For softness, the 6% Bokbunja sauce was the most preferred with a score of 9.36 points. The overall-acceptability was in this order: 6>9>3>0>12%, Thus, from the physico-chemical and sensual perspective, the 6% Bokbunja sauce is highly recommended for potential commercial use. In conclusion, we examined the effect of combining Bokbunja, which has medicinal applications and excellent functionality, with Teriyaki sauce and the results of this study indicate that Bokbunja combined Teriyaki sauce produce a high quality food that holds promise for commercialization.

  • Background: Radix et Rhizoma Ginseng (thereafter called ginseng) has been used as a medicinal herb for thousands of years to maintain people's physical vitality and is also a non-organ-specific cancer preventive and therapeutic traditional medicine in several epidemiologic and preclinical studies. Owing to few toxic side effects and strong enhancement on body immunity, ginseng has admirable application potential and value in cancer chemoprevention. The study aims at investigating the chemopreventive effects of ginseng on cutaneous carcinoma and the underlying mechanisms. Methods: The mouse skin cancer model was induced by 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate. Ultraperformance liquid chromatography/mass spectrometry was used for identifying various ginsenosides, the main active ingredients of ginseng. Comprehensive approaches (including network pharmacology, bioinformatics, and experimental verification) were used to explore the potential targets of ginseng. Results: Ginseng treatment inhibited cutaneous carcinoma in terms of initiation and promotion. The content of Rb1, Rb2, Rc, and Rd ginsenosides was the highest in both mouse blood and skin tissues. Ginseng and its active components well maintained the redox homeostasis and modulated the immune response in the model. Specifically, ginseng treatment inhibited the initiation of skin cancer by enhancing T-cell-mediated immune response through upregulating HSP27 expression and inhibited the promotion of skin cancer by maintaining cellular redox homeostasis through promoting nuclear translocation of Nrf2. Conclusion: According to the study results, ginseng can be potentially used for cutaneous carcinoma as a chemopreventive agent by enhancing cell-mediated immunity and maintaining redox homeostasis with multiple components, targets, and links.

  • Choo-Joo(鄒澍;1790-1844) was the medicine scholar who lived in the late peroid of the Chung-Dynasty and wrote "Bon-Kyung-So-Jeung(本經疏證)", "Bon-kyung-Sok-So(本經續疏)", "Bon-Kyng-Seo-So-Yo(本經序疏要)". In the books mentioned above, He annotated the chief effectiveness of herbal medicine(本草) which had been presented on "Shin-Nong-Bon-Cho-Kyung(神農本草經)" and "Myoung-Eui-Byul-Lok(名醫別錄)". He defined medical action of 315 herb-items with the many theories of various scholars. Scholars whom Choo-Joo has qoutated belong to the school of study of Chinese classics, and they have regarded "Hwang-Je-Nae-Kyung(黃帝內經)", "Shin-Nong-Bon-Cho-Kyung(神農本草經)" and "Sang-Han-Lon(傷寒論)" as great important cannon and have lived during the Myoung Chung Dynasty. The distinctive character of Choo-Joo belongs to similar academic traditions. It seems that he was appected mainly by "Bon-Cho-Gang-Mok(本草綱目)" written by Lee-Si-Jin(李時珍), Mok-Jung-Soon(繆仲淳)'s "Sin-Nonng-Bon-Cho-Kyung-So(神農本草經疏)", You-Yak-Guem(劉若金)'s "Bon-Cho-Sul(本草述)" and Yang-Si-Tae(楊時泰)'s "Bon-Cho-Sul-Gu-Won(本草述鉤元)". He contributed in two big sides. First, Choo-Joo(鄒澍) have achieved much contribution in biliographical study of Chinese classics(考證學). He analyzed the medical theory of herb-medicine, combining with "Nae-Kyung(內經)", "Sang-Han-Lon(傷寒論)" and many theory of various scholars in order to make research on the chief effectiveness that had been presented in "Shin-Nong-Bon-Cho-Kyung(神農本草經)". Therefore the practical application of medical theory and term which had been represented on classics were offered. Secondary, Choo-joo did great accomplishment in pharmacology. The point of his theory was grasping the effect of a medicine through distinctive one beyond general feature. He set up standards that grasp distintive feature as form, color, energy and taste, place of production and temper. And on the basis of these standards he investigated distinctive feature on various fields, then he induced 'the Uem-Yang-0-Haeng Theory(陰陽五行說)' from distictions. According to the these method of classification, form(形) stand for the resultant shape of herbal function, color(色) represent the active direction of herb, energy and taste(氣味) imply the ultimate active function of herb, the place of production(産地) and the period of occurrence(發生時期) symbolize symptoms. When he applied these method to seek for effetiveness, he regarded the field which revealed most representative feature as of great importance, and Combining remained distinctions with one another, he determined more accurate medicinal value. These method of obsevation solved contradiction which occured by equaly appling all medical herbs for the regular standard. The most important theory that represented in Choo-Joo(鄒澍) is to induce and to certify the distintive feature of herb into the 'Uem-Yang-0-Haeng Theory'. That is, concluded as "spring(生), growing(長), change(化), collecting(收) and storing(藏)". As the results of these studies, he made clear the action of medicine more concretly and made 'the Uem-Yang-0-Haeng Theory(陰陽五行說)' more concret and actual for applying. And he contrbuted to establish the standard for grasping the effect of medicines.

  • Garlic (Allium sativum L.) has long history of reputed value and actual use for its medicinal, antimicrobial and pesticidal properties. This study was conducted to find possible developments to natural food preservatives and natural antimicrobials from garlic extracts. The antimicrobial activities of raw garlic extract, heat, pH, temperature against pathogenic bacteria were investigated. E. coli, S. Enteritidis, L. monocytogenes, and S. aureus exhibited antimicrobial activities at 20% garlic extract, but no antimicrobial activity was seen in E. faecium. Raw garlic extract and garlic extract heated for 2 min at $95^{\circ}C$ showed strong antimicrobial activities, but the antimicrobial activity of garlic extract heated for 10 min at $95^{\circ}C$ was much less. The antimicrobial activities of 50% garlic extract adjusted pH 4.0~7.0 showed much the same, but the antimicrobial activities decreased at pH 8.0 or higher. The antimicrobial activities by storage $-18^{\circ}C$ of garlic extract showed much the same. When five strains were cultured for 72 hr at $35^{\circ}C$ in the TSB containing 1~10% garlic extract, viable cell number of five strains were decreased to $10^0{\sim}10^4$ CFU/ml even at 1% or 2.5% (E. faecium) after 24 hr, but later increased to $10^4{\sim}10^9$ CFU/ml after 72 hr. When five strains were cultured for 21 day at $4^{\circ}C$ in the TSB containing 1%, 2.5%, 5%, and 10% garlic extract, viable cell number of E. coli, S. Enteritidis, and S. aureus were decreased to $10^3$, $10^0{\sim}10^2$, $10^1{\sim}10^4$ CFU/ml after 21 day, respectively, but L. monocytogenes and E. faecium increased to $10^8$ and $10^6$ CFU/ml after 21 day.

  • The aim of this work was to determine the chemical composition of essential oil from aerial partsof Mentha arvensis L. f. piperascens (MAO) and to evaluate the effect of its fragrant chemicals on electroencephalographic (EEG) activity of human brain. The MAO was obtained by supercritical $CO_2$ extraction. The maximum yield was 2.38% at conditions of $70^{\circ}C$ and 200 bar. There were 32 volatile chemicals with 6 alcohols (67.11%), 13 hydrocarbons (17.05%), 9 esters (11.50%), 2 ketones (7.16%), 1 oxide (2.77%), and 1 aldehyde (0.56%). The major components were (Z,Z,Z)-9,12,15-octadecatrien-1-ol (50.06%), 2-hydroxy-4-methoxyacetophenone (7.50%), and 3,4-dihydro-8-hydroxy-3-methyl-1H-2-benzopyran-1-one (6.60%). Results of the EEG study showed that inhalation of MAO significantly changed the EEG power spectrum values of relative gamma, relative fast alpha, and spectral edge frequency 90%. During the inhalation of MAO, the value of relative fast alpha was significantly increased (p<0.05). On the other hand, the values of gamma and the spectral edge frequency 90% were significantly decreased (p<0.05). The present study suggests that fragrant chemicals of essential oil of M. arvensis reduce the level of mental stress and that they could be used in the treatment of psychophysiological disorders.

  • The present study describes the cytotoxic effect of Artemisia fukudo extracts. The extract from A. fukudo by 80% ethanol was fractionated with n-hexane, dichloromethane, ethylacetate, and butanol in serial. The cytotoxicity of A. fukudo extracts was examined for its effect on the growth of HL-60 cells by the colorimetric 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay. In addition, we used the HL-60 cells to see what effects the A. fukudo extracts will have on apoptosis of cancer cells. We checked the cell activity, cell morphologic changes, DNA fragmentation, and DNA content after 24 hr incubation with administering 25 ${\mu}g/mL$ of the A. fukudo extracts. In the treatment of the low concentration of n-hexane and dichloromethane fractions, the survival rate of HL-60 cells is lower than that of the control. The laddering-pattern DNA fragmentation was observed in the treatment with n-hexane and dichloromethane fractions. The DNA content of the cells apoptosis measured as the density of sub-$G_{1}$ hypodiploid cells by flow cytometric analysis. The number of sub-$G_{1}$ hypodiploid cells increased in the treatment with n-hexane and dichloromethane fractions. These fractions obstructed the cell cohesion and caused the blebbing of the cell membrane and fragmentation of the nucleus, both of which are symptoms of apoptosis. These results suggest that A. fukudo has a great potential value as food additives, medicinal supplements for patients with chronic diseases, and preventive measures against cancer.

  • Chronological aging and photoaging affect appearance, causing wrinkles, pigmentation, texture changes, and loss of elasticity in the skin. Phragmites communis is a tall perennial herb used for its high nutritional value and for medicinal purposes, such as relief from fever and vomiting and facilitation of diuresis. In this study, we investigated the effects of ethanol extract of P. communis rhizome (PCE) on skin aging. The total flavonoid and total phenolic content in PCE were 2.92 ± 0.007 ㎍ of quercetin equivalents (QE) and 231.8 ± 0.001 ㎍ of gallic acid equivalents (GAE) per 100 mg of dried extract (n = 3). The half-maximal inhibitory concentration (IC50) values of PCE for 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and hydrogen peroxide scavenging activities were 0.96 and 0.97 mg/mL, respectively. PCE showed inhibitory effects on tyrosinase when L-tyrosine (IC50 = 1.25 mg/mL) and L-3,4-dihydroxyphenylalanine (IC50 = 0.92 mg/mL) were used as substrates. PCE treatment up to 200 ㎍/mL for 24 h did not cause any significant cytotoxicity in B16F10 melanocytes, human dermal fibroblasts (HDFs), and HaCaT keratinocytes. In B16F10 melanocytes, PCE (25 and 50 ㎍ /mL) inhibited melanin production and cellular tyrosinase activity after challenge with α-melanocyte-stimulating hormone (α-MSH; p < 0.05). In HDFs, PCE suppressed the mRNA expression of matrix metalloproteinase-1 (MMP-1) and reduced the activity of elastase (p < 0.05). In addition, ultraviolet B (UVB)-mediated downregulation of hyaluronic acid synthase-2 gene expression in HaCaT keratinocytes was also effectively suppressed by PCE treatment. Overall, our results showed that PCE has potential anti-skin aging activity associated with the suppression of hyperpigmentation, wrinkle formation, and reduction in dryness. PCE is a promising candidate for the development of an anti-skin aging cosmetic ingredient.

  • Ginseng is one of the most well known medicinal plant in East Asia with many bioactivities. The purpose of this study was to evaluate the quality properties of cookies added with different concentrations (0, 1, 3, and 5%) of ginseng powder by molecular press dehydration (MPD) method. MPD was known to be an excellent tool for keeping taste and flavor without any loss of original materials. The results indicated no significant difference in the density of cookie dough with different concentrations of ginseng powder. The L color value was decreased and the a color values were increased with increasing concentrations of ginseng powder (p<0.05). However, there was no significant difference in the b values. Spread factor of cookie was not significantly different between 1% and 3%, but decreased at 5% (p<0.05). The hardness of cookies was significantly increased as ginseng powder concentration increased. The result of sensory score showed that cookie added with 1% ginseng powder had higher color, sweetness, overall acceptability scores than other samples. As a result of this study, quality of cookies with added 1% ginseng powder were the most suitable in terms of its color, texture, and sensory properties.
