  • 새로이 명명된 완도호랑가시나무(Ilex $\times$ wandoensis C. F. Miller & M. Kim hybrid nov.)는 전남 완도군 완도에서 채집하였다. 완도호랑가시나무는 호랑가시나무(I. cornuta Thunb.)와 감탕나무(I. integra Thunb.)의 자연교잡을 통해 형성된 분류군이다. 따라서 가시형 엽연과 평평한 표면을 가진 신분류군은 사각형으로 뒤틀린 엽연에 강한 가시형 거치와 볼록한 표면을 가진 호랑가시나무와 전연이며 평평한 표면을 가진 감탕나무의 중간형질을 가지고 있다. 또한 완도호랑가시나무는 소교목이고 1.0-1.4cm의 엽병을 가진 점에서 관목이고 0.4-0.6cm의 엽병을 가진 호랑가시나무와 키가 큰 교목이고 1.5-2.0cm의 엽병을 가진 감탕나무와 뚜렷이 구별이 된다.

  • These studies had performed a plans for preservation and distribution of Ilex cormuta community Mt. Keumsung($35^{\circ}05'\;N,\;126^{\circ}04'\;E$) in Naju, Chonnam from Arpil, 1997 to October by Braun-Blanquet' method(1964). According to the vegetation table of community, the plant communities of the investigated sites were classified Ilex corunta-Trachelospermum asiaticum var. intermedium commnity. Now there still remains the natural environment to be developed in coast district around the riverside distributing Ilex cornuta Lindl., so it has scientifically high value to predict change of the ecosystem and preserve the community distribution. It needs plan for preservation high value to predict change of the ecosystem and preserve the community distribution. It needs plan for preservation

  • The objectives of this study were investigation of the sutiable propagation method by softwood cuttings of female Ilex serrata, the comparison of sex determination of Ilex serrata after seeding and the fruiting percentage of the Ilex serrata male and female. The results obtained were as follows. 85 percentage of the seed were germinated with three months cold stratification. 35 percentage of female plant were observed after seeding. Cuttings should be rooted on late June using a quick dipping of 1,000ppm IBA solution. The rooting rate of the softwood cuttings treated IBA 1,000pm on June 22 in a closed moist chamber with 50% shade screen was 72.2 percentage. The suitable planting of male and female of Ilex serrata was male one versus female thirteen in a distance of 50 meter.

  • Six compounds were isolated from the twigs of Ilex macropoda. Their structures were elucidated as betulinic acid, lupeol, betulone, betulin, erythrodiol and 11-oxo-erythrodiol by physicochemical and spectroscopic analysis. Among them, lupeol, betulone, erythrodiol and 11-oxo-erythrodiol were isolated for the first time from this plant.

  • Methanol extract of Ilex pubescens roots prolonged bleeding time threefold, and inhibited the generation of malondialdehyde released during platelet aggregation inducted by thrombin. Through several purification procedures, its saponin, named ilexoside, was proved to be responsible for the antithrombotic activities of the plant. Ilexosides A, -D and -J and 24-carboxypomolic acid showed strong inhibitory activities on platelet aggregation induced by thrombin.

  • Four triterpenoids were isolated from the roots of Ilex pubescens : two new triterpenoids named pubescenolic acid (I) and pubescenic acid (II), and two known triterpenoids ilexolic acid (III) and oleanolic acid (IV). Chemical and spectroscopic studies have established I and II as 20-epipomolic acid and 24-carboxypomolic acid, repectively.

  • Tar spots have been observed on Ilex cornuta in Korea since 2015. Based on morphological and molecular analyses, the fungus responsible was determined to be a Rhytisma species, with characteristics similar to R. ilicis-latifoliae observed on Ilex latifolia from Japan. Herein, we document the first report of Rhytisma sp. on I. cornuta.
