  • The insecticide constituents of several Celastraceae family plants including Celastrus angulatus, Celastrus orbiculatus, Celastrus flagellaris, Euonymus verrucosides, Euonymus forunei and Euonymus phellomana were studied by bioassay-guided fractionation. All structures of sesquiterpene polyol esters and alkaloids have been elucidated by UV, IR, MS, NMR and x-ray diffraction evidences. These compounds exhibited insecticidal, antifeedant and narcotic activities against Mythimna separata.

  • Ray cells with perforations are recorded for the first time in the Korean Celastraceae species of Euonymus sieboldiana and Tripterygium regelii and the Oleaceae species of Abeliophyllum distichum, Forsythia ovata, Ligustrum japonicum, and Osmanthus heterophylla, All these anomalous ray cells have simple perforations, and the vessel elements of all these species have simple perforation plates, Thus, in the Korean Celastraceae and Oleaceae, the perforations of ray cells appear to be identical with the types of perforation plates in the vessel elements of the same wood, The diagnostic value of the perforated ray cells is also discussed.

  • Tripterygium wilfordii Hook.f. (Celastraceae), collected from Phia Oac-Phia Den National Park of Vietnam, is reported here as a new generic and species record for the flora of Vietnam. The genus Tripterygium differs from other genera of Celastraceae by its samara fruits, which become three-winged at maturity, and a scandent shrub. Taxonomic notes, descriptions, line drawing and photographs are provided, together with short notes on the distribution, ecology and phenology of Tripterygium wilfordii Hook.f. (Celastraceae).

  • 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.

  • 백두산에서 화살나무속의 신종인 백두산회나무(Euonymus baekdusanensis M. Kim)를 새로이 발견하여 기재하였다. 백두산회나무는 4수성 꽃구조를 가지고 4개로 각이 진 삭과를 가지며 사마귀 같은 혹이 가지와 소지에 있어 회목나무(E. verrucosus Scopoli)와 유사하다. 그러나 백두산회나무는 커다란 장타원형의 잎(11-13 cm)을 가지고 엽병이 뚜렷하며(6-8 mm) 과실이 대형(12-15 mm)인 반면에, 회목나무는 작은 도란형의 잎(6-7 cm)을 가지고 엽병이 거의 없으며(1-2 mm) 과실이 소형(6-8 mm)인 점에서 두 종이 뚜렷하게 차이가 난다.

  • A new celastraceae alkaloid, euojaponine C has been isolated from the methanol extract of the root bark of Euonymus japonica. With the relative stereochemistry of euojaponine C established by NOESY data, the absolute stereochemistry has been determined by circular dichroism (CD) exciton chirality method. The CD of the 2, 5-bis-phenyl benzoate of triacetonide derived from the LiAlH$_{4}$, hydrolysate, euonyminol shows that the configuration of C-2 and C-5 are both R.

  • A new oleanane-triterpene, 3${\beta}$-acetoxy-11${\alpha}$-benzoyloxy-13${\beta}$-hydroxyolean-1 2-one (1), was isolated along with a known quinone-methide triterpene, pristimerin (2), from the root bark of Siphonodon celastrinneus Griff., a Thai medicinal plant of the family Celastraceae. Their structures were determined based on spectroscopic analysis.
