본 실험에서는 Thuja 속 7종(Thuja orientalts, T. orientalis 'Avrea Nana', T. orientalis cv. compacts, T. occidentalis, T. occidentalis 'Boothii', T. occidentalis 'Pumila', T. occidentalis 'Tiny Tim')의 침엽에 함유된 monoterpenenoids를 GC-MS로 분석하여 종간을 비교하였다. 분석결과 총 30종류의 성분이 검출되었는데 그 중 α-pinene, camphene, sabinene, myrcene, limonene, bonyl aetate, γ-terpinene, α-terpinenyl acetate는 7종 식물모두에서 검출되었다. Thuja속 7종에서 추출된 monoterpenenoids는 종간에 차이가 나타났으며 Thuja orientalis 'Avrea Nana'(11 Compounds)는 가장 작은 성분이 나타났고 Thuja occidentalis 'Pumila'(26 Compounds)는 가장 많은 종류의 성분이 검출되었다. 검출된 성분을 토대로 종간의 유사성을 PAUP(Phylogenetic Analysis Using Parsimony) 프로그램으로 분계분석을 하였다. 분계도는 4가지 형태가 나타났고 Thuja occidentalis와 Thuja occidentalis 'Boothii'가 가장 유사한 유연관계를 보였다.

The natural dyeing of silk fabric with Thuja orientalis extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Thuja orientalis extract were 100% v/v, $80^{\circ}C$, 80 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods with increasing mordant concentration. Light colorfastness and washing colorfastness of Cu or Fe mordanted silk fabric was improved by mordanting. The antibacterial properties of dyed and mordanted silk fabric showed a high reduction rate, and Thuja orientalis extract was showed effective bacterial reduction. The dyed and mordanted fabric with Thuja orientalis extract showed a superior ultraviolet protection property.

To elucidate phytotoxic effects on the growth of receptor plant, germination and growth experiment of selected species have been performed with aqueous extracts and volatile substances of leaf and of donor plant, Thuja orientalis. The extracts of T. inversely proportional to the concentration. Gas chromatography method was employed for analysis and indentification of phytotoxic substances from T. orientalis. Forty-two kinds of KDICicals including ${\alpha}-thujone$ were identified from T. orientalis essential oil. Bioassay was performed with 6 KDICical such as ${\alpha}-pinene, \;{\alpha}-terpinene, \;{\gamma}-terpinene, \; {\beta}-myrcene$, and among them bornyl acetate was the strongest growth inhibitor.

Evaluation of larvicidal activities of Chamaecyparis obtusa and Thuja orientalis oils against 4th-instar larvae of Aedes aegypti and Culex pipiens pallens revealed larvicidal activities of leaf oils extracted from C. obtusa and T. orientalis were significantly higher than those of stem, fruit, and seed oils. Strong mortality was observed in age class II of C. obtusa and T. orientalis against Ae. aegypti and Cx. pipiens pallens larvae. These results show both leaf part and age class II of C. obtusa and T. orientalis have strong larvicidal activity against Ae. aegypti and Cx. pipiens pallens. Leaf oils of C. obtusa and T. orientalis leaves show promise as natural larvicides against Ae. aegypti and Cx. pipiens pallens.

Water and alcohol extracts were prepared from dried and powdered leaves of Thuja orientalis (T. orientalis). The reducing power, total phenolic content, the 1,1-diphenyl-2-picrylhydrazyl scavenging activity, inhibitory effect on Fe (II)-EDTA-$H_{2}O_{2}$ (Fenton reaction system) induced DNA damage and inhibitory effect on human red blood cell (RBC) hemolysis were evaluated in the present study. At a concentration of 200 mg, water and alcohol extracts of T. orientalis inhibited the hydrolysis of DNA by 72.859% and 65.312%, respectively. Water and alcohol extracts of T. orientalis also inhibited 2,2'-Azobis(2-amidinopropane) dihydrochloride induced RBC hemolysis to the extent of 69.30% and 54.55%, respectively. The reducing power and antioxidative activity of water extract was found to be more than that of alcohol extract. This is attributable to the presence of higher amount of phenolic compounds in water extract. The present results indicate that the T. orientalis extracts are rich sources of natural antioxidants and can protect DNA and human red blood cells against free radical induced oxidative damage.

측백나무 잎을 채취하여 건조시킨 후 분말로 제조하여 아세톤-물(7:3, v/v)로 추출하고 hexane, CH₂C1₂, EtOAc, 그리고 수용성으로 분획하여 동결건조 시켰다. 그 중에서 EtOAc 분획을 Sephadex LH-20으로 충진한 칼럼에서 메탄올과 에탄올-헥산 혼합액을 용리용매로 사용하여 칼럼크로마토그래피를 실시하였다. 단리된 화합물들은 TLC로 확인한 후 NMR스펙트럼을 사용하여 정확한 구조규명을 하였고 FAB-MS로써 분자량을 측정하였다. 주로 quercetin-3-O-a-L-rhamnopyranoside와 myricetin-3-O-α-L-rhamnopyranoside 같은 flavononol 유도체들이 다량으로 포함되어 있었으며 비교적 적은 양의 (+)-catechin과 (+)-gallocatechin 같은 flavan 화합물들도 함께 단리 되었다. 각 분획물들과 단리된 화합물들은 DPPH 라디칼 소거법을 이용하여 항산화실험을 실시하였으며, 모두 우수한 항산화 효능이 있는 것으로 나타났다.

본 연구는 천연기념물(62호)인 충북 영천리 측백나무(Thuja orientalis)림의 직경과 흉고단면적 생장모형을 추정하여 측백림의 관리에 필요한 기초 자료를 제공하고자 45본의 표준목을 선발하여 생장추를 이용하여 목편을 채취한 후 기초(non-overlapping) data와 데이터 재배열을 통한 overlapping data를 이용하여 최적의 흉고직경과 흉고단면적 추정식을 선정하였다. 동형 및 다형의 비선형 생장식을 데이터에 적합한 결과 overlapping data를 이용한 다형 방정식이 우수한 적합성을 보였다. 흉고직경 생장은 Schnmacher 다형 방정식인 $D_2={\exp}({\ln}(D_1)(T_1/T_2)^{0.4495}+3.8535(1-(T_1/T_2)^{0.4495}))$, 흉고단면적 생장은 Schnmacher 다형 방정식인 $BA_2={\exp}({\ln}(BA_1)(T_1/T_2)^{0.1235}+11.3793(1-(T_1/T_2)^{0.1235}))$가 가장 우수한 식으로 판명되었다. 본 연구에서 제시된 측백림의 흉고직경과 흉고단면적 생장식은 천연기념물인 측백림의 관리 경영에 필요한 정보로 이용할 수 있을 것으로 판단된다.

Thuja orientalis extract (TOS) has been used on the hemostatic roborant, sedatives and stressless in oriental countries. We investigate the inhibitory effects on the productions of pro-inflammatory cytokines such as interleukin-1beta (IL-1β), IL-6, tumour necrosis factor alpha (TNF-α), and nitric oxide (NO) and the hair promotiont of TOS in the macrophage celline RAW264.7 or hair loss-induced DBA1J mice. T08 (50-500 ㎍/㎖) per se had no cytotoxic effect non-stimulated cells, but this extracts concentration-dependently reduced the release of NO, (IL-1β), IL-6, and TNF-α in the stimulate RAW264.7 cells with lipopolysaccharide (LPS). Moreover, when applied TOS (500 ㎍/㎖) to DBA 1J/mice, hair growth was promoted remarkably. These data suggest that T08 promotes hair growth on hair loss induced model mice and these properties may contribute to the anti- hair loss activity of the Thuja orientalis.

Litterfall, decomposition, and dynamics of n and p in decomposing litter were investigated for 2 years in red pine ( pinus densiflora) and chinese thuja( thuja orientalis)stands in the limestone area. Average litterfall in red pine and chinese thuja stands were 4, 535kgDM ha-1 yr-1 and 5, 010 kgDM ha-1 yr-1, respectively. Seasonal litterfall in red pine and chinese thuja stands showed peaks in November. concentrations of N and P in the needle litter were lowest in the winter when the greast litterfall occurred, and highest in the summer when the least litterfall occurred. However, those in chinese thuja scale leaf litter showed litter seasonal variation.amount of N and P returned to the forest floor through litterfall were 29.02kgN ha-1 yr-1 , 2.81 kg P ha-1 yr-1 for red pine stand, and 31.06 kg N ha-1 yr-1 , 2.86kgP ha-1 yr-1 for chinese thuja stand, respectively. After 21 mounts elapsed, needle and chinese thuja scale leaf litterbags lost 34.8% and 32.5% of the initial weight, respectively. N concentrations in the docomposing needle and chines thuja scale leaf litter decreased by 19% and 30%, respectively, after 1 month elapsed, and then gradually increased to exceed the initial concentration after 9 months elapsed and then gradually increased to exceed the initial concentration after 9 months elapsed in both of them, P in needle and chines thuja scale leaf litter decreased by 54% and 57% of the initial concentration, respectively, after 1 month elapsed. unlike N, P concentration in the decomposing litter did not exceed that of initial ones. Neyt immobilization period of N and P in decomposing litter did not occur over the study period.
