  • 최근 남성성탈모증에 대한 관심이 증대되고 있으며, 이에 천연물 및 그의 활성성분을 활용한 새로운 약물 개발에 대한 연구가 증가하고 있다. 송지(Resina Pini, RP)는 Pinus sp. (Pinaceae)의 수지질로 전통의학적으로 감염, 우식증, 치주질환에 사용되어왔다. 본 연구진은 RP의 성분인 아비에트산(abietic acid, AA)이 남성성탈모기전에 중요한 효소인 $5{\alpha}$-reductase를 억제하는 효과를 세포 수준에서 입증한바 있으며, 이번 연구에서는 실제로 탈모억제 및 모발 성장에 대하여 실험동물 수준에서 입증하고자 한다. C3H/HeN 탈모마우스 모델에서 RP는 300 mg/kg에서 유의하게 탈모억제를 확인하였으며, 뿐만 아니라 AA는 30 mg/kg에서도 유의하게 탈모억제효과를 보였다. 이상의 결과로부터 RP는 그 활성성분인 AA가 $5{\alpha}$-reductase 억제하는 기전을 통해 남성성탈모억제효과를 보였다고 사료되며, 향후 탈모억제 보완치료법으로의 이용 가능성을 보였다.

  • The antioxidant activity of Pinus densiflora was determined by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The methanol extract of P. densiflora showed strong antioxidant activity, and thus fractionated with several solvents. The antioxidant activity potential of the individual fraction was in the order of ethyl acetate>n-butanol>water>dichloromethane> n-hexane fraction. The ethyl acetate soluble fraction exhibiting strong antioxidant activity was further purified by repeated silica gel column chromatography. Antioxidant (+)-catechin was isolated as one of the active principles from the ethyl acetate fraction, together with the inactive components, dihydrokaempferol and 1-O-benzoylglucose. The radical scavenging effect of (+)-catechin on DPPH radical exceeded to that of L-ascorbic acid which is a well known antioxidant.

  • 한국산 나자식물 6개과에서 대표적인 1종씩을 선정하여 수피의 특징을 형태 및 해부학적으로 조사하고 기재하였다. 수피를 인위적으로 조직단위로 간주할 경우 수피의 색, 두께, 내수피와 외수피의 두께, 확장조직의 유무 및 발달정도, 조피내 주피의 층우와 주피의 층수와 주피의 구성요소들의 두께, 2기 사부지역 각 구성요소들의 배열양상과 점유면적 비율 등은 종류에 따라 차이를 보였다. 또한 보강세포의 형태와 사세포의 사역 등도 앞으로 상세한 조사가 수행될 경우 비교형태학적 연구에 매우 가치있는 정보를 제공할 것으로 생각되었다.

  • 일본잎갈나무잎을 채취하여 아세톤 : 물 (7 : 3, v/v) 의 혼합용액으로 추출한 후 에틸아세테이트용성 화합물과 수용성 화합물로 분리하였으며 Sephadex LH-20으로 충진한 칼럼을 사용하여 화합물을 단리 하였다. 단리 화합물을 확인하기 위하여 셀룰로오스 박층 크로마토그래피(TLC)를 실시한 후 자외선 램프 하에서 관찰하였다. 바닐린 발색제를 분무히여 정색반응을 조사하고 $R_r$ 값을 구하였다. 단리된 화합물들의 구조는 $^1H$-NMR과 $^{13}C$-NMR 스펙트럼을 이용하여 그 구조를 규명하였으며 에틸아세테이트용성 화합물에서는 (+)-catechin, (-)-epicatechin, kaempferol-O-arabinofuranoside와 kaempferol-3-O-arabinopyranoside, 수용성 화합물에서는 apigenin-8-C-rhamnosyl-($1"'{\rightarrow}2"$)-glucoside(2"-O-rhamnosylvitexin)을 단리 하였다.

  • An investigation was done to know the warty layer structural difference in bordered pit of longitudinal tracheid in Pinus densiflora Sieb. et Zucc., Pinus koraiensis Sieb. et Zucc., Pinus rigida Mill. and Larix kaempferi Carr. grown in Korea. Among the four wood species, warty layer was found in bordered pit of longitudinal tracheid of Pinus densiflora Sieb. et Zucc. and Pinus rigida Mill. The mean height and horizontal diameter of warty layer was found highest in Pinus densiflora Sieb. et Zucc. The height of warty layer was found the highest in juvenile wood of Pinus densiflora Sieb. et Zucc. and it gradually decreased towards the matured wood.

  • An experiment was conducted to investigate the pit structure of four kind of pine wood species grown in Korea. Torus diameter, margo width, margo lattice size, diameter of pit aperture and pit border width were taken under consideration for explaining the pit structure difference among Pinus densiflora, Pinus rigida, Pinus koraiensis and Larix kaempferi. Torus diameter was found highest in Pinus rigida and the lowest in Pinus densiflora. Margo lattice size varied with torus diameter. Wider torus lowered the margo lattice size. Highest margo width was found in Pinus rigida while the lowest one was found in Pinus koraiensis. Pit aperture diameter was found highest in Pinus densiflora and lowest in Pinus koraiensis. In Pinus rigida, pit border was found the highest and the lowest was found in Larix kaempferi. Pit aperture diameter and pit border were increased gradually from pith to bark while there was a decreasing trend in the margo lattice size measuring from the pith to bark.

  • 본 실험은 한국산 주요 침엽수인 소나무, 잣나무, 리기다소나무, 낙엽송의 safranine의 침투도를 실험하였다. 진공, 압력 및 safranine의 침투시간을 각각 다르게 하여 수종별 침투도를 측정하였다. 실험 결과 진공조건의 변화에 따른 침투도 변이는 크게 나타나지 않았고, 압력조건의 차이에 의한 침투도는 다르게 나타났다. 목재의 방향별 침투도를 고찰한 길과 축방향, 방사방향, 접선 방향의 순서로 침투도가 높았다. 변재와 심재의 사이의 침투성을 고찰 한 결과 변재가 심재보다 쉽게 침투 되었다. 수종별 침투성을 고찰한 결과 소나무가 가장 우수했다.

  • We investigated endophytic fungi diversity of two Pinaceae species (Pinus densiflora, Pinus rigida) and one Cupressaceae species (Juniperus rigida) on Mt. Seodae, Korea. In total, 34 isolates were obtained from 19 host plants and identified according to internal transcribed spacer (ITS) region. As a result, they were placed in 13 taxa. Among them, 52.9% belonged to Leotiomycetes, 32.3% belonged to Sordariomycetes, 5.8% belonged to Agaricomycetes, and 3.0% for isolates belonged to either Eurotiomycetes, Dothideomycetes or Ustilaginomycetes. In particular, Lophodermium growing in pine would be an especially important instance of biodiversity for endophytes, suggesting that further study examining its ecological function in the environment is critical.

  • Levels of total lipids in the seeds of three species of the Pinaceae family were determined and their fatty acid compositions were also analyzed by a gas-chromatograph equipped with a capillary column coated with Carbowax 20M. The results are summarized as follows: Lipid contents of the seeds amounted to 56.9% in P. koraiensis, 29.9% in P. thunbergii, and 21.2% in P. rigida. In all lipids 19${\sim}$20 fatty acid were detected and, surprisingly, fatty acids having ${\Delta}^5$-non-methylene interrupted conjugate double bond such as ${\Delta}^{5, 9}-C_{18:2},{\Delta}^{5, 9, 12}-C_{18:3}\;and\;{\Delta}^{5, 11, 14}-C_{20:3}$ occurred in appreciable amounts. In the lipids of P. koraiensis, the main component was $C_{18:2}{\omega}_6(45.0%)$, followed by $C_18:1{\omega} _9(26.9%)$ and ${\Delta}^{5, 9, 12}-C_{18:3}(14.6%)$, and then ${\Delta}^{5, 9}-C_{18:2}(2.2%)$ and ${\Delta}^{5, 11, 14}-C_{20:3}$ were also present. Levels of saturated fatty acid such as $C_{16:0}\;and\;C_{18:0}$ were as low as 7.5%. The seed oil of P. thunbergii predominantly comprised $C_{18:2}{\omega}_6(45.2%)$, and was then occupied by equal amounts ${\Delta}^{5, 9, 12}-C_{18:3}(18.1%)$ and $C_{18:1}{\omega}_9(18.1%)$. Its ${\Delta}^5, 11, 14}-C_{20:3}(5.8%)$ level was the highest in the samples tested. ${\Delta}^{5, 9}-C_{18:2}(2.8%)$ was also detected with other minor components. In the oils from the seeds of P. rigida, $C_{18:2}{\omega}_6$ was present as a main component, accompanied by $C_{18:1}{\omega}_9(21.6%)$ and ${\Delta}^{5, 9, 12}-C_{18:3}(20.3%)$. The latter showed higher level than in any other samples. A minor component corresponding to ${\Delta}^{5, 9, 12, 15}-C_{18:4}$(not confirmed by GC-Mass) occurred in P. thunbergii and P. rigida.
