  • PBDEs의 조성, 발생원 및 지역적 농도 분포를 확인하기 위해 국내의 여러지역(서울, 안성, 청주, 울산, 대구, 부산, 파도리)에서 자생하는 소나무 잎을 채취하였다. Hepta-BDE부터 deca-BDE까지의 동족체(homologs) 농도는 총 PBDEs의 농도와 매우 유의한 상관성(Pearson 상관계수 r>0.96, p<0.001)을 보였다. Deca-BDE는 다른 homologs에 비해 모든 시료에서 최대농도를 나타내었다. PBDE 함유 제품(Bromkal 70-5DE, DE-71)과 소나무 중 침착된 PBDE 동질체(congeners) 사이의 상관성이 높게 나타나 PBDE 함유 제품이 본 채취지점에서 발생원으로 평가되었다. 또한 BDE-47, -99, -100, -206, -207 및 -209는 모든 소나무 잎에서 주된 성분을 나타내었는데 이는 전세계적으로 다량 사용된 penta-BDE와 deca-BDE 함유 제품이 국내에도 다량으로 사용되었기 때문으로 판단된다. 그러나 BDE-209와 BDE-47, -99, -100간의 상관성은 유의하지 않았는데 이는 tetra-BDE와 penta-BDE는 대기-토양 분배와 같은 2차 발생원에 영향이 지배적인 반면 deca-BDE는 여전히 1차 발생원의 영향이 2차 발생원의 영향보다 지배적이었기 때문으로 판단된다.

  • The effect of allelochemicals on growth, root nodule nitrogen fixation activity, and ion patterns of soybeans were investigated. We prepared 50 g/L (T50), 100 g/L (T100), and 200 g/L (T200) extract concentrations by soaking fresh red pine needles in a nutrient solution. Adding needles to the nutrient solution increased the content of total phenolic acids, osmolality, and total ions. The total phenolic content in the T50, T100, and T200 extracts were $206{\pm}12.61$, $335{\pm}24.16$, and $603{\pm}12.30$ mg gallic acid equivalents, respectively. The $K^+$, $Mg^{2+}$, $Ca^{2+}$, and $PO_4^{3-}$ content increased by adding needles to the nutrient solutions, whereas $SO_4^{2-}$ content decreased. The growth inhibition of soybeans was proportional to the needle extract concentrations, and the T100 and T200 concentrations resulted in remarkable growth inhibition. On day 20 after treatment, dry weight and nitrogen fixation activity of the root nodules were reduced by the T100 and T200 treatments, whereas the T50 treatment was not difference from the control. After day 10, total ion content in all treatment groups was not different in comparison with the control. However, total ionic content in all treatment groups decreased significantly compared with that in the control after day 20. The lowest total ion value was found for the T200 concentration. The T200 treatment also resulted in significantly reduced $SO_4^{2-}$ content. The amounts of $Mg^{2+}$, $Ca^{2+}$, and $Mn^{2+}$ were higher than those of the control for the T50 treatment on day 10 and for T100 on day 20 after treatment. A significant increase in osmolality was observed in the T200 treatment on day 10 and in the T100 treatment on day 20. These results suggest that under severe allelochemical stress conditions, a remarkable reduction in nodule formation, nitrogen fixation activity, and ion uptake eventually resulted in a decrease in leaf production. Furthermore, increased $K^+$, $Mg^{2+}$, $Ca^{2+}$, $Mn^{2+}$, and osmolality in soybeans exposed to lower concentrations of allelochemicals than the critical stress level helped overcome the stress.

  • 솔잎에 포함되어 있는 flavonoid들은 free radical 소거능이 탁월하다고 알려져 있다. 이들 중 특히 proanthocyanidin은 심장혈관 보호작용과 항산화 활성에 크게 기여하고 있다. 지리산 적송잎으로부터 열수, 에탄올, 헥산 및 아임계 장치를 이용하여 추출물을 제조하여 총 폴리페놀성 물질 중에 포함된 proanthocyanidin의 함량을 측정하였다. 그 결과, 총 폴리페놀성 물질 및 proanthocyanidin의 농도가 열수 추출물의 경우 가장 높게 나타났으며, 에탄을 추출물, 헥산 추출물, 아임계 추출물 순으로 낮아졌다. 한편, 각 추출물들의 총 폴리페놀성 물질의 농도에 대한 proanthocyanidin의 함량을 계산한 결과, 아임계 추출물의 경우 가장 높은 함량을 보였고, 헥산 추출물, 에탄을 추출물, 열수 추출물 순으로 낮아졌다. 이러한 결과로 적송잎을 열수 및 에탄올로 추출한 경우 높은 농도의 총 폴리페놀성 물질 및 proanthocyanidin이 포함된 추출물을 얻을 수 있다는 사실을 알 수 있었다. 또한, 아임계 추출물의 경우 비록 추출물에 포함된 총 폴리페놀성 물질의 농도는 낮지만 이들 대부분이 proanthocyanidin으로 이루어진 시료를 얻을 수 있다는 사실을 알 수 있었다 각 추출물에 대한 항산화 활성을 측정한 결과, 열수 추출물의 경우 가장 높은 활성을 보였으며 에탄올 추출물도 비교적 높은 활성을 타나냈다. 이상의 결과에서 솔잎으로부터 4가지 추출법에 의해 제조된 추출물을 비교 분석한 결과, 열수 추출물에서 가장 높은 기능성 성분 함량 및 항산화 활성을 나타냈으므로 솔잎을 이용한 기능성 식품의 추출 가공법 선택에 있어 좋은 자료로 활용될 수 있을 것으로 생각된다.

  • In this research, the improvement of Korean rice wine (makgeolli) with pine (Pinus koraiensis) extract addition was evaluated due to the increase in alcoholic Korean traditional beverage. Makgeolli fermentation was prepared using Korean rice and nuruk (traditional starter) supplemented by pine needle (MPN) and pine sprout (MPS) extract. The average of initial pH level for MPN was 3.95 and MPS was 4.55, the average of initial sugar content for MPN was 0.4% and MPS was 0.3%. The sugar content and pH level behavior were investigated every 24h during fermentation period. The observation of microbial colony was done at days 8 of fermentation period with three time sample dilution. Afterward, the physical appearance of fermentation solution and microbial development were investigated in the final of fermentation period. The number of yeast and LAB ($402{\times}103\;CFU/mL$) in MPN was greater than the yeast and LAB count in MPS ($224{\times}103\;CFU/mL$). The pH level obtained by addition pine sprout have value of R2 higher than addition of pine needles (leaf), the sugar content (%) behaviour was opposite with pH level behaviour.

  • The study of carbonaceous aerosols in the atmosphere is critical to understand the role of aerosols in human health and climate. Using standardized thermal optical transmittance methods, organic carbon (OC), elemental carbon (EC), and water soluble organic carbon (WSOC) were determined using a combustion sampling system for four types of agricultural crop residues (rice straw, red pepper stems, soybean stems, and green perilla stems) and eight types of forest trees (pine stems, pine needles, ginkgo stems, ginkgo leaves, maple stems, maple leaves, cherry stems, and cherry leaves). The aerosol particles between 0.056 and $5.6{\mu}m$ in size were analyzed using a Micro-Orifice Uniform Deposit Impactor (MOUDI). In the current study, the Carbonaceous Thermal Distribution (CTD) by carbon analyzer was discussed in order to understand the carbon fractions from the twelve types of biomass burning. Also, the concentration of OC, EC, WSOC, and water insoluble organic carbon (WIOC) detected in the emissions were described.

  • "濟衆立效方" is the oldest Koryo dynasty medical document known to date. Despite its historical importance, due to the absence of its original copy, its true characters could not be understood. Through comparison of the many documents that cited 濟衆立效方, it could be found that 濟衆立效方 can be classified into two parts based on its contents and form. In Chinese medical texts, neither the name 交效散 nor any similar prescription is mentioned. 濟衆立效方 was the first in suggesting the usage of pine needles and salt for fomentation and not for internal use. Thus 交效散 can be thought of as the oldest indigenous prescription preserved in Korean history. 濟衆立效方 conveys records of the combination of the ancient origin pine needle fomentation and the creative addition of salt.

  • This study was carried out to investigate spectral characterisistics and chlorophyll contents of Pinus koraiensis needles in Gwangju-gun, Kyunggi-do. In spectrum analysis by each age, needle showed difference on 700∼1,100 nm(NIR : near infrared ray). Light reflexibility keeps constant between 1st year needle and 3rd year needle, current year needle's value was higher than others and that was higher for 400∼500 nm and 600∼700 nm at 550 nm. Transmission to needle's age showed the highest result in current year needle. It showed in order of current, 1st, 2nd and 3rd year needle at 550 nm and 750 nm. Especially, current year needles of Pinus koraiensis showed a tendency to change transmission coefficient in NIR. The result of transmission coefficient measurement by each position of slope showed in order of middle slope, upper slope and lower slope. But the gathered needle in middle slope made marked change at NIR. Chlorophyll a content of the upper slope's needles was higher than other 4 positions but a component ratio was lower. In needle of the oppressed tree, Chlorophyll a content was rather low than others. Chlorophyll a content by slope positions, the upper slope's needle showed a highest value(4.48 mg/g) and lower slope was lowest value(1.35 mg/g). Chlorophyll b content also showed a similar tendency to chlorophyll a and chlorophyll(a+b) contents.

  • This study was conducted to evaluate whether pine needle extracts can be used as tobacco flavors. Yield of essential oil, absolute and oleoresin extracted from pine needles is 0.07%, 1.20% and 6.08% respectively. The volatile compounds isolated from the three types of extracts were analyzed by gas chromatography(GC) and mass selective detector(MSD). Total 72 components were identified in the three type of extracts including 26 hydrocarbons, 16 alcohols, 13 esters, 9 acids, 4 phenols, 2 aldehydes and 2 ketones compounds. The major components were $\beta$-pinene, $\beta$-caryophyllene, $\delta$-cadinene and 4,5-dimethyl-1,3 -dioxol-2-one. There were 49 volatile components in the absolute, 44 components in the essential oil and 26 components in the oleoresin. The content of hydrocarbons and alcohols was higher in the essential oil extracted by simultaneous distillation extraction(SDE) than in others, while that of esters and acids was higher in the absolute than in others. Especially, phenols and ketones were identified only in the oleoresin. The components such as $\beta$-pinene, bornyl acetate, $\alpha$-terpineol and oxygenated terpenes have characteristic piney and fresh green odor. The contents of these components was higher in the essential oil and the absolute than in the oleoresin. Therefor, the essential oil and the absolute are expected to be more useful than the oleoresin as tobacco flavor.
