  • The Abies koreana Wilson has been unique species of Korea and has not been clearly investigated about lignans of extractives. This studies have been carried out from the isolation and determination of lignans from alcoholic extractives in its xylem. Six lignans were isolated and their structures were determined by spectroscopic methods. They were two new compounds, (+)-koreslactol and (-)koreanol and four known compounds, lariciresinol p-coumarate, (+)-todolactol C, (-)-${\alpha}$-intermedianol, and (+)-pinoresinol.

  • 구상나무(Abies koreana Maximowicz)와 전나무(Abies holophylla Wilson) 잎을 채취하여 건조시킨 후 분말로 제조하여 각각 1.5 kg을 아세톤-물(7:3, v/v)로 추출하고 헥산, 메틸렌클로라이드, 에틸아세테이트 및 수용성으로 분획하여 동결건조 시켰다. 에틸아세테이트용성 분획을 Sephadex LH-20으로 충진한 칼럼에서 메탄올과 에탄올-헥산 혼합액을 용리용매로 사용하여 칼럼크로마토그래피를 실시하였다. 단리된 화합물들은 TLC로 확인한 후 $^1H-$, $^{13}C-NMR$, COSY, HETCOR 등의 스펙트럼을 사용하여 정확한 구조를 규명하였고 FAB 및 EI-MS로써 분자량을 측정하였다. 많은 양의 aromadendrin-7-O-${\beta}$-D-glucopyranoside (화합물 III), polydatin (화합물 VI), (-)-rhododendrol-2-O-${\beta}$-D-glucopyranoside (화합물 VII)가 단리되었으며, 소량의 (+)-catechin (화합물 I), kaempferol-3-O-${\beta}$-D-glucopyranoside (화합물IV), myricetin-3-O-${\beta}$-D-glucopyranoside (화합물 V), naringenin-7-O-${\beta}$-D-glucopyranoside (화합물 II)도 단리 되었다. DPPH 라디칼 소거법을 이용하여 단리된 화합물들에 대한 항산화 활성시험을 실시하였으며 (+)- catechin과 polydatin이 항산화 효능을 나타내었다.

  • 산업발전에 따라 환경분야가 대두됨에 따라 민감성 피부에 화장품을 사용하는데 있어 부작용이 증가하였다. 이에 따라 저자극성 방부제의 개발을 위하여 항암효과가 입증된 침엽수 중 구상나무, 향나무의 활성성분을 추출하여 항균력을 측정 평가하였다. 항균력 측정에는 Broth dilusion법이 사용되었으며, 균주는 그람 음성균인 Escherichia coli와 그람 양성균인 Staphylococcus aureus를 사용하였다. 그 결과 항균효과는 향나무와 구상나무가 625 ppm에서 methyl paraben에 비하여 각각 17.02 %, 8.5 % 더 높은 효과를 나타냈다. 항산화 효과 측정은 DPPH법, 총 폴리페놀 함량은 Folin-Denis법, 총 플라보노이드의 함량은 Nieva Moreno법을 사용하여 분석하였다. 항산화 효과에서 향나무는 5,000 ppm에서 45 %, 구상나무는 44 %의 항산화 효과를 나타냈으며 분석 결과 총 폴리페놀과 총 플라보노이드 함유량과 비례하였다. 침엽수 추출물의 세포독성실험은 피부섬유아세포인 CCK-986sk를 사용하였다. 그 결과 향나무, 구상나무가 39 ppm에서 1,250 ppm까지의 모든 농도에서 95% 이상의 높은 세포 생존률을 나타냈다. 이상을 종합해 본 결과 향나무 줄기, 구상나무 잎은 합성물질을 대체할 수 있는 방부제 및 보조 항산화제로서 사용이 가능하다고 할 수 있다.

  • Structure and dynamics of Abies koreana community in Mt. Gaya were studied to provide the basic data for conservation of Abies koreana community, an endemic species in Korea. A. koreana community of this study site was composed of tree layer (4~7m), subtree layer (2~4m), shrub layer (1~2m), and herb layer (below 1m). The heights of tree and subtree layers were low. Floristic composition showed that this study site was subalpine and dry site. In frequency distribution diagram of diameter classes of major species consisting of A. koreana community, those of both A. koreana and other species showed reverse J-shaped types. From these results, it was estimated that A. koreana community of this site might be maintained continuously as a stable climax state like present state. In the spatal distribution diagram of major species, saplings of A. koreana were established under the canopy of A. koreana and Pinus koraiensis and under the dead tree of A. koreana. From these results, it was known that A. koreana saplings were recruited before the community was disturbed and regeneration was accomplished by advance regeneration pattern, in which these saplings established before occurrence of disturbance fill with open site originated from death of mature tree. Growth of annual rings was variable among individuals, it was estimated that such variation was originated in that growth of each individual relates to microclimatic conditions rather than macroclimatic ones. Ecological longevity of A. koreana in this study site estimated by disturbance types and age of dead trees was about 120 years.

  • This examination of vegetation is conducted from June to Oct. 1999 through on the spot survey, centering on the habitat of Abies koreana around Imgeolryeong, Jangteomok, and Jeseokbong in Mt Jiri and Yeongsil path and Seongpanak path in Mt. Halla. Species composition tables of the Abies koreana community by altitude and slope in Mt. Jiri and Mt. Halla are made based on the community composition tables examined in quadrat. The Abies koreana-Saso quelpaertensis community in a west slope of Mt. Halla is found that Abies koreana of 4-6m in height forms subtree layer and that of 8-9m in height the tree layer and it reflects a difference between community structure by slope and main composition species. While the tree layer of Abies koreana community is 12-14 in height around the area of 1,290-1,560m above the sea of Imgeolryong and path from Baekmudong to Jangteomok, it is 8-12m in height in the area of 1,680-1,780m above the sea of path from Jangteomok to Jeseokbong. It means that community structure depends on area and attitude. This study finds out that commonly appearing composition species similar to coverage and presence are Lepisorus thunberianus, Quercus mongolica, Solidago virga-aurea var. asiatica, Ligularia fischeri, Carex lanceolata, Clintonia udensis, Magnolia sieboldii, Betula ermani, Acer pseudo-sieboldianum. As soil environment of surveyed area, pH of surveyed spots is similar in Mt. Jiri and Mt. Halla, electrical conductivity is higher in Mt Jiri, and contents of organic matter is relatively higher in a west slope of Mt. Jiri and Mt. Halla and lower in their south and west slopes. Contents of organic matter and total nitrogen show that the area of 1,550m above the sea in a west slope of Mt. Halla is some higher. For pH and contents of total nitrogen and organic matter, Mt. Halla is higher than Mt. Jiri but for electrical conductivity, Mt. Jiri is relatively higher than Mt. Halla.

  • The floristic composition of the Korean-fir(Abies koreana Wilson) forest on Mt. Halla in Cheju Island, Korea, was described and some other phytosociological features were noted. The dense tree layer of the Abies koreana forest under consideration attained a height of no more than 5-7m. The shrub layer was 1.2-2m high and usually inconspicuous, while the herb layer, 0.3-0.5m high, was remarkable. The forest contained a number of species which are characteristic of the subalopine coniferous in Japan, particularly that in Hokkaido. Moreover, the specific synchronized regeneration called wave-regeneration was found in the forest on Mt. Halla at several sites even though the data on this phenomenon do not present in the present report.

  • This study investigated the protective effects of shade nets on Abies koreana seedlings subjected to high temperature and luminosity stress, which are pertinent for plant survival in climate change scenarios. This study, conducted at Konkuk University, compared the growth, survival, and soil conditions of 3-year-old specimens across natural, greenhouse, and shaded settingsfrom July to September 2022. Our findings demonstrated that shade nets significantly enhanced seedling survival by moderating soil temperature and moisture. This is particularly evident in high-temperature conditions, where shade nets mitigate stress on seedlings and safeguard them from excessive sunlight exposure. Proper net installation height and location are crucial for optimal temperature and humidity control, suggesting broader applicability for various species and offering strategies to combat the ecological impacts of climate change.

  • This study was undertaken to compare the biomass of Abies koreana growing at two sites. A $10{\times}10m$ plot was established in each site of a natural stand in Mt. Jiri and a plantation in Gyeongsan nursery. Five trees of A. koreana were randomly selected in each site. The following traits were investigated from each tree : height, basal diameter, age, weight of stem, branches, and needles as above-ground traits and weight of total roots, horizontal roots, and vertical roots as below-ground traits. In Gyeongsan nursery, age of sample trees was negatively correlated with both height and weight of total stem, while height was highly correlated with weight of horizontal roots. There was high correlation between the basal diameter and weight of total stem, and between the basal diameter and weight of roots. In Mt. Jiri stand, most of the above-ground traits except age were significantly correlated with the below-ground traits. The linear regression equation between the cross section area of base (X) and the weight of total stem (Y) in Gyeongsan nursery was Y=12.66X-12.92, and correlation was significant ($R^2=0.89$). The linear regression equation between the cross section area of base(X) and the weight of total branches (Y) in Mt. Jiri stand was Y=25.51X+6.00, and correlation was highly significant ($R^2=1.0$).
