  • Wild edible plants are consumed as raw and/or processed. Analytical data for raw biologically functional compounds were relatively well established. The changes on functional compounds during processing are, however, not well studied. This study was carried out to investigate the change of the quality of wild edible plants, Pimpinella brachycarpa(Chamnamul) at various conditions. Samples were blanched at the salt concentration of 0%, 1% or 2% for 1, 2, and 3 minutes each. The biologically active compounds, vitamin C, ${\beta}-carotene$, chlorophyll, flavonoids, polyphenols and minerals were analyzed. The concentration of vitamin C in Chamnamul decreased as blanching time increased. Beta-carotene in Chamnamul showed high concentration when Chamnamul was treated under longer blanching time. Higher salt concentration of blanching water, however, resulted in the increased concentration of ${\beta}-carotene$ in the blanched Chamnamul. Higher salt concentration of blanching water also reduced the loss of total flavonoids and total polyphenols from the blanched Chamnamul. The change of colors in the blanching water seemed to be corresponding to those of total flavonoids and total polyphenols concentrations in the blanching water.

  • 인삼품질에 대한 전통개념을 역사적 경험, 전통적 품질관리방법 및 분석적 방법과 관련하여 조사하였다. 전통개념은 생명과 우주가 하나라는 한국의 기본사상에 근거한 것으로 보인다. 전통품질관리법에서 모양과 크기는 특정한 조직, 세포 및 세포내의 생리적 활성물질을 규정하기 때문에 전통품질관리법은 분석방법이 활성물질을 찾아가는 지도가 될 것이다. 전통법은 생물활성 물질간의 균형이 한 물질의 함량보다 중요하며 인체의 항샹성을 위한 활성물질의 작용양식도 여러 화합물, 여러 목표체계인 것으로 보인다. 인삼이 클 수록 중심부가 더 빨리 크고 중심부에는 질소화합물이 많기 때문에 전통법은 질소 화합물 특히, 수용성 단백질과 열안정단백질들이 활성물질의 균형에 있어 중요함을 강력히 시사한다. 생물활성물질의 균형은 삼속의 종간 사용방법의 차이와 의미있게 관계를 보인다.

  • One hundred and seventeen crude drugs were screened for DNA-binding activity in vitro. The DNA-methyl green assay is a useful biochemical screen for the detection or development of biologically active compounds which bind to DNA. This assay is based upon the fact that free methyl green undergoes rapid spontaneous molecular rearrangement to its colorless carbinol base so that the liberation of the dye from DNA by displacement can be followed spectrophotometrically as a decrease in absorbance at 65Onm. Seven methanolic extracts of crude drugs including Cinnamomi Cortex spissus, Coicis Semen, Coptidis Rhizoma, Perillae Semen, Plantaginis Semen, Polygalae Radix and Zanthoxyli Fructus showed less than 2,000${\mu}$g/ml as their $IC_{50}$ values. The active principles of Plantaginis Semen and Zanthoxyli Fructus were transferred into organic solvents, which showed the $IC_{50}$ values with 588 and 574${\mu}$g/ml, respectively. These fractions have been selected for isolation of biologically active constituents.

  • Livestock products like meat, milk and egg have been principal food sources for human beings since the historic periods of time. Nowadays consumption of these food items have been avoided due to its high contents of SFA, cholesterol and total fat which are major culprits of chronic adult diseases causing major deaths of people. However, the relationship between livestock products and diseases is not always true because the amounts of fat and cholesterol and types of fatty acids in meat and meat by-products depend on the part of the meat and types of animals. Although meat intakes do not always cause mai or adult diseases, still the developmental necessity does exist for animal foods equipped with biologically active properties, which in turn can improve nutritional status and health more than ever Meat with high protein lean part and low fat can be produced by applying synthetic somatotropin and beta-adrenergic agonists like clenbuterol, cimaterol etc. during breeding. This application brings benefits like higher growth rate, lower fat contents and improve feed efficiency ratios. Meats fortified with long chain PUFA($\omega$-3 fatty acids) can also be produced by modulating feed composition.Egg Products have faced the reduced sales annually because of its high cholesterol contents. Recently brand eggs fortified with special nutrients or chemical components having functional proper ties in the human body system are very popular Research Interests have been focused on eggs with low cholesterol and high omega-3 fatty acids. Low cholesterol eggs and high omega-3 eggs can be produced in several different ways, but popular way to increase is feeding the feeds with different oil sources containing high omega-3 and 6 fatty acids such as fish oil, perilla oil, linseed oil and lecithin etc. But proper compositon of feed formula should be found and economically beneficial. Brand eggs fortified with vitamin, mineral, unknown growth factors are also manufactured. Low cholesterol and high $\omega$-3 PUFA milk are marketed recently Cholesterol removal technology is not completely established and has several limitations to be overcome. Milk fortified with $\omega$-3 fatty acids is made by incorporating high &13 fatty acid foods in feed despite of extraordinary way of fatty acid metabolism In cow. All these biologically active products will be very beneficial and useful for human consumption when limitations of manufacturing technology such as safety and lowered sensory qualities are resolved. Furthermore, thorough and precise tests and quality control for these products should be performed to ensure the effectiveness and usefulness in terms of improving health and nutritional status in general. However one caution should be pointed out to lay people informing that these items are nothing but a food and not panacea. Therefore, it is important to remember that the only way of maintaining good health is absolutely through consuming balanced diet.

  • The present study aimed to investigate the effects of low temperature on the growth, yield, quality, and biologically active compounds of strawberry and obtain basic information for developing a technology for stable growth of strawberry in greenhouses. Growth of strawberry, including leaf number, area, and length, plant height, and dry weight was better at the optimum growth temperature of $20^{\circ}C$ than at a lower temperature of $15^{\circ}C$. At the low temperature of $15^{\circ}C$, the cultivar 'Maehyang' was more tolerant and displayed better growth rate than 'Seolhyang'. At $15^{\circ}C$, the fruit production per week and fruit weight was lower than that at $20^{\circ}C$. In contrast, fruit length and diameter were not significantly different between the two growth temperatures. Growth temperature also did not affect the fruit color index, Hunter L, a, b value, or fruit firmness. However, the sugar content of strawberries grown at $15^{\circ}C$ was higher by 0.8 and 1.5 Brix for 'Seolhyang' and 'Maehyang', respectively, than of those grown at $20^{\circ}C$. There was no difference in the content of fisetin, a biologically active compound, for 'Seolhyang' at both growth temperatures, however, the fisetin content of 'Maehyang' was higher at $20^{\circ}C$ than at $15^{\circ}C$. Cinchonine and ellagic acid content of 'Seolhyang' was higher at $20^{\circ}C$ than at $15^{\circ}C$, whereas that of 'Maehyang' was higher at $15^{\circ}C$ than at $20^{\circ}C$. Quercetin content showed no significant differences with respect to growth temperature, however, it tended to increase at $20^{\circ}C$. The cinnamic acid content of 'Seolhyang' was higher at $15^{\circ}C$ than at $20^{\circ}C$, whereas that of 'Maehyang' increased at $20^{\circ}C$. Collectively, the biologically active compounds of strawberry were affected by growth temperature. Moreover, the content of these compounds tended to increase at $20^{\circ}C$, the optimum growth temperature, rather than at the sub-optimal growth temperature of $15^{\circ}C$.
