A new species, Euonymus baekdusanensis M. Kim (Celastraceae), has been named and described from Mt. Baekdu of the Korean peninsula. Euonymus baekdusanensis shares several characteristics (4-merous flowers, 4-angled capsule, warted branches and twigs, etc.) with its related species E. verrucosus Scopoli. It is, however, distinct from E. verrucosus which have small oblong leaves (6-7 cm), short petioles (1-2 mm), and small capsules (6-8 mm) by having large elliptical leaves (11-13 cm), long petioles (6-8 mm), and large capsules (12-15 mm).

전국 어디서나 쉽게 볼 수 있는 사철나무는 노박덩굴과 식물로 해풍과 염기에 강하며 해수와 접하여도 잘 죽지 않고, 또한 내음력이 강하며, 습지와 건조지에서도 강하며 맹아력이 좋고 공해에도 강하여 정원수나 조경수로는 적격인 수종이라 할 수 있겠다. 이러한 까닭에 도심지의 조경수, 관상수, 정원수로 많이 식재되고 있고 잘 정돈된 사철나무 울타리는 도시인의 마음을 한결 깔끔하게 하고 화려하지는 않지만 은은하여 도시에서 느낄 수 없는 소박한 시골 아낙네 같은 청초한 느낌을 준다. 봄과 여름에는 다른 수종들과 어울러져 남들을 더욱 돋보이게 하고 가을과 겨울에는 혼자만이 꿋꿋이 녹색을 띠면서 적막한 도시의 거리를 조금이나마 부드럽게 하는 현대인이 배우고 갖추어야 할 덕목을 일러주는 나무인 것이다. 이러한 사철나무를 가해하는 해충으로 깍지벌레류와 진딧물류의 피해가 심하고, 기타 잎을 가해하는 왕물결나방, 차주머니나방이 피해를 주고 있어 이들에 대한 생태 및 방제법을 간략하게 소개하고자 한다.

The presence of saponin, terpenoid, steroid, anthraquinone and flavonoid were screened with the usual test methods in forty five(sixty four parts) Korean plants belonging to Urticaceae, Celastraceae, Rhamnaceae, Sterculiceae and Rubiaceae. Plants were extracted with methanol and fractionated with hexane, chloroform, ethyl acetate and butanol. Each fraction was tested for the components. The result showed that in saponin test, 21 plants were positive and 11 plants were weak positive; in terpenoid and steroid test, 26 plants were strong positive; in anthraquinone test, 20 plants strong positive; in flavonoid test, 31 plants were positive and 9 plants were weak positive.

This study was carried out to investigate the antioxidative and antimicrobial activities of Celastrus orbiculatus (CO). CO was extracted with methanol and then further fractionated with n-hexane (COMH), butanol (COMB), methanol (COMM) or aqueous (COMA) to get active fractions. The antioxidative activity of fractions from CO was investigated by measuring the scavenging activities of CO against DPPH radical, peroxynitrite ($ONOO^-$) and reactive oxygen speicies (ROS). Among the various solvent fractions, the COMB showed a marked scavenging effect against DPPH radical, peroxynitrite ($ONOO^-$) and reactive oxygen species(ROS). The antimicrobial activity was increased in proportion to its concentration by the paper disk method. Among the various solvent fractions, the COMM and COMB fractions of CO showed strong antimicrobial activities. The results suggest that The CO may be suitable for development as a food preservative and alternative antioxidant.

During the floristic survey on Phnom Bokor National Park, Kampot, Cambodia, we encountered Balanophora fungosa var. indica, which is a tropical holoparasitic plant. To identify its host species, we collected host roots and trees nearby and tried to identify them using DNA barcoding approach. We applied plastid rbcL and matK gene regions as DNA barcode markers, and successfully amplified and sequenced the markers from 15 host roots and seven tree samples. Obtained host root sequences were identified as Primulaceae, Celastraceae, Myrtaceae, and Oleaceae, while trees nearby are Oleaceae, Myrtaceae, Sapindaceae, Rosaceae, Clusiaceae, Ericaceae, and Lauraceae. At genus level, host species are identified as Myrsine, Euonymus, Syzygium, and Olea, but failed in species discrimination. Myrsine (Primulaceae) and Olea (Oleaceae) are reported here as host species of B. fungosa var. indica for the first time. Further sampling and comparative work, and DNA barcoding will help recognize the biodiversity of the area and host species of Balanophora, together with their evolution.

In the present field study, the number of woody flora of Mt. Songni were summarized as 44 families, 89 generas, 140 species, 10 varities and 2 forms. Also, the flora among inland areas such as Mt. Paektu, Mt. Sorak, Mt. Songni, and Mt. Chiri, and insular areas, such as Oyoujong Island. Tokjok Archipelago, Kok-unsan Archipelago and Cheju Island, were compared, respectively, in order to interpret the characteristics of distribution patterns of the flora of this area. The flora of Mt. Songni were characterized as similar to the flora of Mt. Sorak, and also with that of Mt. Chiri. It was interpreted both the northern types of plants such as Aceraceae, Araliaceae, Fagaceae, Tiliaceae and Ulmaceae and the southern types of plants such as Celastraceae, Convolvulaceae, Euphorbiaceae, Rhamnaceae, Solanaceae, Crassulaceae and Urticaceae were fluxed considerably into this region.

The present scientific scenario shows that, the long-distance dispersal of any species plays a major role in population as well as the flow of individual between populations. However, newly recorded plant at Dokdo was confirmed by using morphological and molecular markers of nrDNA and cpDNA. This scientific study has identified the plant species was as a Euonymus hamiltonianus Wall. (Celastraceae). And after careful studies, the laboratory results shows that the distribution of tree species at Dokdo as an Oceanic Island is a meaningful thing because of the inflow of plant in adverse condition of environment such as a shallow soil layers and steep terrain. So it is necessary to continuous monitor for the inflow of non-indigenous plant into Dokdo.

This study suggested the adaptable plant species according to the change of warmth index (WI) through the Representative Concentration Pathway (RCP) 4.5 & 8.5 climate change scenarios from 2010 to 2099 in Seoul areas. From the scenario analysis results, we expected to change from the cool temperate souther forest zone to the warm temperate forest zone. We found the following adaptable 27 plant species: 6 species in the tree layer, Quercus serrata, Q. variabilis, Pinus densiflora, Q. acutissima, Styrax japonica and P. thunbergii etc.; 7 species in the shrub layer, Ligustrum obtusifolium, Lespedeza maximowiczii, Rhus trichocarpa, Callicarpa japonica, Rubus crataegifolius, Rosa multiflora, and Zanthoxylum piperitum etc.; 3 species in the herb layer, Oplismenus undulatifolius, Pteridium aquilinum var. latiusculum, and Commelina communis ect;, 11 species in the vine plants Smilax china, Cocculus trilobus, Parthenocissus tricuspidata, Lonicera japonica, Paederia scandens, Celastrus orbiculatus, Clematis apiifolia, Rubus parvifolius, Dioscorea batatas, Hydrangea serrata for. acuminata, Zelkova serrata etc.

Objectives: The aim of this study was to determine whether celastrol, the triterpenoid component of Celastrus orbiculatus, offers neuroprotection against Parkinson's disease (PD) in mice administered 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine(MPTP). Methods: We examined how celastrol affected MPTP-induced neuronal loss of tyrosine hydroxylase (TH)-positive dopaminergic neurons in substantia nigra pars compacta (SNpc) in the midbrain of mice. C57BL/6J mice were divided into four groups: (1) saline-saline, (2) saline-celastrol, (3) MPTP-saline, and (4) MPTP-celastrol. The mice were injected intraperitoneally (i.p.) with four administrations of MPTP (18mg/kg) at 2 h intervals and then i.p. administered celastrol (3mg/kg) two times at 12 h after last celastrol administration. Expression of TH on the SNpc of brain tissues were analyzed at 7 days after the treatments by immunohistochemistry and Western blot. Results: Immunohistochemical analysis using TH antibody showed that celastrol provided significantly protective effects against MPTP-induced loss of TH-positive dopaminergic neurons in the SNpc region of the midbrain of mice. Our Western blot study also showed that celastrol significantly inhibits the MPTP-induced neuronal damage via the up-regulation of TH protein levels in MPTP mice. Conclusions: The present results suggest that it may be possible to use celastrol for the prevention of nigral degenerative disorders including PD, caused by exposure to toxic substances.
