  • Thrombogenesis and atherosclerosis are mainly caused by platelet aggregation, blood coagulation, and hyperlipidemia. Platelet aggrelation, activated platelet thromboplastin time (APTT) were measured as indexes of blood coagulation and lipid contents in the subjects who have taken red ginseng products (e.g. water extract, tea, drink etc.) for 4 to 5 years. The platelet aggregation in the red ginseng-taking group was significantly decreased, as compared with the non-red ginseng-intaking group, when platelets were stimulated by 100 $\mu\textrm{g}$/ml of collagen (P<0.01). The atherogenic index and the ratio of triglyceride to HDL-cholesterol in blood, the risk factors of atherosclerosis, were decreased in the subjects of ginseng group, compared with that in control group. APTT was also prolonged to greater extent in ginseng group than in control group. These results suggest that long-term intake of ginseng products may help to prevent the risks of thrombogenesis and atherosclerosis.

  • The purpose of this study was to evaluate the selective marinates, red win, ginger, ginseng, and green tea, for improving the sensory characteristics of pork hind legs. The marinated samples of pork hind legs were analyzed for their physicochemical propenies and sensory characteristics. Especially, overall acceptabilities of them were compared with bacon the most palatable pork meat to Koreans. After marinating, all the meats except the red wine marinated meat showed pH increase. After cooking, all the marinated meat including red wine marinated meat recorded further pH increase. The water holding capacities(WHC's) of the marinated meats except the ginger one showed a tendency of decrease. however, who's or all the cooked meats were increased greatly. Only the L-value or the green tea marinated meat increased After cooking, the L-values of the red wine and ginseng marinated meats were lower than that of the unheated cooked meat The a-value of the green tea marinated meat recorded the lowest In the hardness and gumminess test all the marinate treatments showed lower values than the control did. the brittleness of all the marinated meats except the ginger one decreased The flavor of the cooked ginger marinated meat was improved to the similar level of bacon. The textures of all the treatments except the green tea marinated meat were improved the overall acceptability of the ginger or ginseng marinated meat improved greatly to $87.6\%$ of bacon$(100\%)$.

  • Administration of ginsenosides, a mixture of saponin extracted from Panax ginseng, decreased blood pressure in rat. Previous studies have shown that ginsenosides caused endothelium-dependent relaxation, which was associated with the formation of cyclic GMP, suggested that ginsenosides caused release of nitric oxide (NO) from the vascular endothelium. The aim of the present study was to characterize the endothelium-independent relaxation to ginsenosides in the isolated rat aorta. Ginsenosides caused a concentration-dependent relaxation of rat aortic rings without endothelium constricted with 25 mM KCI but affected only minimally those constricted with 60 mM KCI. Ginsenoside Rg3 (Rg3) was a more potent vasorelaxing agonist than total ginsenoside mixture and also the ginsenoside PPT and PPD groups. Relaxation to ginsenosides were markedly reduced by TEA, but not by glibenclamide. Rg3 significantly inhibited Cal'-induced concentration-contraction curves and the "50a2'influx in aortic rings incubated in 25 mM KCI whereas those responses were not affected in 60 mM KCI. Rg3 caused efflux of $"Rb in aortic rings that was inhibited by tetraethy- lammonium (TEA), an inhibitor of Ca"-dependent K'channels, but not by glibenclamide, an inhibitor of AfP-dependent K'channels. These findings indicate that ginsenosides may induce vasorelaxation via activation of Ca2'-dependent K'channels resulting in hyperpolarization of the vas- cular smooth muscle with subsequent inhibition of the opening of voltage-dependent Caf'channels. These effects could contribute to explain the red ginseng-associated vasodilation and the beneficial effect on the cardiovascular system.

  • HPLC에 의한 카테킨류 5성분의 정량분석법을 검토한 결과, 종래의 이동상을 acetonitril, acetic acid 및 methanol 수용액에서 acetontrile, N,N-dimethyl formamide, ethyl acetate의 0.06% 인산수용액으로 전환하였을 때 컬럼에서의 용출시간을 45분에서 28분으로 줄일 수 있었으며, 특히 (-)-epigallocatechin-3-gallate(EGCG)나 (-)-epicatechin gallate(ECG)의 peak를 종래의 넓은 형태에서 예리한 chromatogram을 얻으므로써 분석값의 오차를 최소화 할 수 있었고 머므름시간$(0.32{\sim}3.97%)$이나 peak 면적$(1.61{\sim}7.02%)$의 변동계수도 신뢰할 수 있는 값을 얻었다. 또한 시판되고 있는 수종의 녹차류와 홍차 및 대만산 오룡차를 분석한 결과 녹차류의 카테킨 함량은 $120.3{\sim}153.7\;mg/g$ 이었고 홍차는 녹차류의 1/4수준 이었다.

  • The effect of sugars, mixing ratio between a sugar and ginseng extract, and moisture content on the physical properties of ginseng tea granules such as water sorption and coagulation phase were investigated The physical Properties of granule were significantly affected by the moisture cogent, a kind of sugars and amount of ginseng extract used in the preparation. The granules contained less than 1.0%moisture and 14.0% of ginseng extract were not affected on the properties, however, it was significantly affected when the moisture content was 1.5 ${\pm}$ 0. 2 % and the ginseng extract was more than 18%. In the preparation with simple sugar, it was significantly decreased water sorption and coagulation phase when lactose used instead of anhydrous glucose. It was also observed that the Properties were decreased as the amount of lactose increased in the preparation of granules with mixing sugars.

  • This study was conducted to investigate the actual conditions of intake of Korean traditional beverages in 273 female university students in Seoul, Korea. The subjects of this study consisted of 128 food and nutrition majors and 145 non-majors. Questionnaires were administered to the subjects who had an average age of 20 years. Two-hundred and nineteen students (80.2%) lived with their parents. Regarding the type of beverages subjects often drink, coffee was the most preferred (51.3%) overall, and non-majors (4.1%) were shown to drink traditional beverages more often. Regarding preference for traditional beverages, most subjects (72.5%) responded that they liked their own traditional beverage. However, for frequency of intake of traditional beverages, 48.7% answered they do not drink any traditional beverages. The reasons why subjects like traditional beverages were taste (71.7%) and health (26.3%), and the type of traditional beverages they often drink were Yulmu tea (35.9%), Sik hae (30.8%), and Yuja tea (10.6%), in order. Regardless of major, ginseng tea, jujube tea, mulberry-leaf tea, Chinese matrimony vine tea, ssanghwa tea, ginger tea, and omija tea were found to be satisfactory traditional beverages. Therefore, due to the low intake frequency, preference, and satisfaction of traditional beverages, new traditional beverages that can meet the standards of female students should be immediately developed.

  • This study was performed to investigate the perception and the preference of Korean traditional foods such as traditional holiday foods, rice cakes and beverages. The subjects were 598 elementary school students(male 310, female 288) in fifth or sixth grades. The most favorite traditional holiday food was rice cake soup(57.4%) and 92.4% of subjects wanted to keep the traditional holiday foods because of the traditional custom. The traditional beverages mainly drinking at home were sikhye(35.6%), misugalou(30.2%), green tea(18.5%), etc. Children's most favorite beverage was misugalou(90.5%) and they had no taste for ginseng tea(39.6%). Children did not know well about booggumi(64.1%), dootubdduk(63.3%), whajun(39.6%), etc. and liked gguldduk(94.2%) better than the others. They liked the rice cake because of its good taste(69.0%) and disliked it because of chocking(30.9%), not eating frequently(29.5%), hard and tough(18.2%), and so on. And they wanted to make the rice cake softer and sweeter like the cake and mostly ate it on the traditional holidays.
