A number of laboratory experimentes have performed to elucidate water-soluble of volatile substances from wormwood plant(artemisia princeps var. orientalis) as growth inhibitor or phytotoxicant. in germination tests with aqueous extracts of leaves, stems and roots of the wormwood plants, most tested species showed that relative germination ratio was inversely proportional to comcentration of the extracats. and seedling elongation and dry weight of the species were heavily inhibited with the extracts, incubated leaves, volatile substances of the leaves and soil underneath wormwood plants. gas Chromatography was employed to find out possible phytotoxic substances or growth inhibitors of wormwood leaves. ten substantes have isolated, and most of them were identified as terpenoids.

Inhibitory effects of the essential oils obtained from ten herbs were tested on acetaminophen-induced lipid peroxidation in the rat. The oil of Artemisia princeps var. orientalis buds (AP-oil) showed the most significant hepatic malondialdehyde value which was comparable to those of ascorbic acid and methionine. This was warranted by the protective effect on hepatic glutathione depletion. Overview of the data on the activities of hepatic microsomal enzymes, aminopyrine N-demethylase and aniline hydroxylase led to the notice that the suppressed activities of those enzymes are mainly responsible for the anti-lipid peroxidation. The interpretation of GC-MS data on the AP-oil revealed the ingredient of cineol, thujone, carvone, borneol, camphor and terpineol.

This study investigated the chemical composition of Artemisia princeps var. orientalis (Pampan) Hara (ssuk in Korea) essential oil and the quantitative changes of major terpene compounds according to the time of harvest. The essential oils obtained by hydrodistillation extraction from the aerial parts of ssuk were analyzed by GC and GC-MS. The essential oil composition of ssuk was characterized by higher contents of mono- and sesqui- terpene compounds. Ninety-nine volatile flavor compounds were identified in the essential oil from ssuk harvested in 2010, with camphor (11.9%), ${\beta}-caryophyllene$ (9.11%), dehydrocarveol (8.51%), and borneol (7.72%) being the most abundant compounds. Eighty-three compounds were identified in the essential oil from the plant harvested in 2011, with borneol (12.36%), caryophyllene oxide (12.29%), ${\beta}-caryophyllene$ (10.24%), camphor (9.13%), and thujone (8.4%) being the most abundant compounds. Eighty-four compounds were identified in the essential oil from the plant harvested in 2012, with ${\beta}-caryophyllene$ (20.25%), caryophyllene oxide (14.63%), and thujone (11.55%) being the major compounds. Eighty-nine compounds were identified in the essential oil from the plant harvested in 2013, with thujone (23.11%), alloaromadendrene oxide (12.3%), and ${\beta}-caryophyllene$ (11.48%) being the most abundant compounds. Thujone and aromadendrene oxide contents increased significantly from 2010 to 2013, while camphor and dehydrocarveol contents decreased significantly during those 4 years. The quantitative changes in these 4 compounds according to the time of harvest can served as a quality index for ssuk essential oil. The ecological responses to recent climate changes may be reflected in the chemical components of natural plant essential oils.

This study was carried out to select proper species for early stage replantation in granite forest roads cut-slope. From one to fourteen year elapsed forest roads in eight regional areas of Gyeongsang-do and Jeolla-do, sample plots were selected, and their vegetations and environmental factors were investigated. Soil organic matter, total nitrogen, soil moisture content, and bulk density in the granite weathering soils were below 0.4%, 0.03%, 12.4%, and above 1.2g/$cm^3$, respectively. The result indicated that the soil was not good for plant growth. The environmental factors affecting distribution of species in the granite forest roads were the elapsed year, elevation, and cut-slope aspect. Invaded species with high frequency in the forest road cut-slope ordered Pinus densiflora, Lespedeza bicolor, Rubus crataegifolius, Alnus hirsuta, Youngia denticulata, Patrinia villosa, Artemisia princeps var. orientalis, Zanthoxylum schinifolium, and Dactylis glomerata. Herbs seeded in earth stage such as Dactylis glomerata, Eragrostis curvula, Festuca arundinacea, Lespedeza sp., and Amorpha fruticosa had changed into perennial herbs and shrubs such as Youngia denticulata, Patrinia villosa, Aster scaber, Patrinia scabiosaefolia, Melica onoei, Astilbe chinensis var. davidii, Chrysanthemum zawadskii var. latilobum, Pueraria thunbergiana, Stephanandra incisa, and Clematis apiifolia, and had changed into plants such as Artemisia princeps var. orientalis, Artemisia keiskeana, Miscanthus sinensis, Pinus densiflora, Rhododendron mucronulatum, Rubus crataegifolius, and Zanthoxylum schinifolium according to elapsed year of forest roads. Leguma such as Lespedeza sp., Pueraria thunbergiana, Amorpha fruticosa, etc., herbs such as Artemisia keiskeana, Artemisia princeps var. orientalis, Chrysanthemum zawadskii var. latilobum, Miscanthus sinensis, etc., and woody plants such as Pinus densiflora, Rubus crataegifolius, Rhododendron mucronulatum, etc., with foreign herbs were considered as proper species for replantation in granite forest road cut-slope.

천연자원에서 향균성 물질을 찾고자 수종의 식용 식물을 검색하는 과정에서 쑥(Artemisia princeps var. orientalis)의 추출물이 항균활생이 비교적 높았다. 쑥의 메탄올 추출물을 겨l통분획한 ethyl acetate 분획물(EtOAc)은 agar diffusion법에셔 항균활성이 가장 높았으며, EtOAc로부터 분리된 화합물 중 0­C coumaric acid(200 -600ppm)는 B. subtilis(12.6 ~ -18.0mm)와 s. typmηwrium( 12.6-16.6mm)에 대하 여 우수한 항균활성을 나타내였고, 그 유도체인 p­C coumanc a디d는 약 1.2 -1.7배 정도의 항균활성을 증가시켰다 Coumaric acid의 3가지는 액체배양에 서 B. subtilis 증식응 모두 강하게 억제하였으며, S. typmmuriuη2, P. aeruginosa 및 s. aureus의 증식 억제에는 각각 0-, m- 및 p-coumaric a디d가 효과적 이었다. B. subtilis의 반고체 agar 배양에셔 pc coumaric acid의 MID는 $\100∼200mu\textrm{g}$/disk였다.

본 연구는 중금속이 낙엽의 분해에 미치는 영향을 알아보기 위하여 충남 청양의 폐금광의 광미에 분포하는 쑥(Artemisia princeps var. orientalis)과 쇠뜨기(Equisetum arvense)를 이용하여 실험하였다. 광미는 높은 중금속 함량과 낮은 유기물 함량을 가지고 있었다. 광미의 중금속 함량은 대조구 토양에 비해 비소(As)는 약 13배, 카드뮴(Cd)은 약 28배 높은 것으로 나타났다. 또한 크롬(Cr), 니켈(Ni) 및 아연(Zn)은 약 3배에서 6배 높게 측정되었다. 광미와 대조구 토양에서 채집한 식물체내의 중금속 함량은 광미에서 채집한 식물에서 현저히 높게 나타났으며, 쑥 잎의 경우 As는 약 23배, Cd은 25배 높게 나타났으며, 쇠뜨기 지상부의 경우 As는 58배, Cd은 11배 높은 것으로 나타났다. 대조구에서 분해 결과 중금속 농도가 높은 쑥의 잎과 대조구에서 채취한 잎이 각각 50.4%, 65.7%가 분해되었다. 또한 광미에서 진행된 분해 결과 쑥의 잎은 폐광지역에서 채취한 잎과 대조구에서 채취한 잎이 각각 31.6%, 57.5%가 분해되었다. 쑥의 줄기의 분해결과도 잎의 분해율과 비슷한 양상을 나타내었다. 쇠뜨기의 지상부의 분해는 대조구에서 분해된 결과 광미에서 채집된 쇠뜨기와 대조구에서 채집한 쇠뜨기가 각각 77.8%와 89.3%가 분해되었으며, 광미지역에서 분해 결과 각각 67.6%와 82.1%가 분해된 것으로 나타났다. 따라서 광미에서 생육하는 식물체의 중금속의 함량이 높을수록 분해가 느린 것으로 나타났으며, 이는 중금속이 낙엽의 분해에 영향을 미친 것이라고 판단된다.
