  • Inter simple sequence repeat (ISSR) markers were performed in order to analyse the genetic relation-ships of both taxa of Gardenia jasminoides var. radicans and G. jasminoides for. grandifora. Over the 88 fragments, only one locus (ISSR-11-05) was specific to G. jasminoides var. radicans and only one (ISSR-09-05) G. jasminoides for. grandiflora. Although G. jasminoides var. radicans showed low levels of alleles and Shannon's information index than G. jasminoides for. Grandiflora, however, there was not significant differences (p > 0.05). For both taxa the mean genetic diversity of natural populations was higher than that of cultivation populations. It was suggested that domestication processes via artificial selection do not have eroded the high levels of genetic diversity. ISSR markers were more effective in classifying natural populations of wild G. jasminoides in East Asia as well as cultivated G. jasminoides. The information about the phylogenetic relationship of G. jasminoides var. radicans and its closely related species is very valuable of the systematics of genus Gardenia, the origin of cultivated G. jasminoides, and future G. jasminoides breeding.

  • The entomopathogenic fungus Zoophthora radicans (Entomophthorales: Entomophthoraceae) was found to infect Cnaphalocrocis medinalis, Plutella xylostella, Myzus persicae and one unidentifed species. Samples of the fungus were collected from three areas (Jinan, Gimje, and Iksan) in Jeollabuk-do, Korea. Infected insects appeared in July and September, during which time population infection rate of Z. radicans on C. medinalis reached up to 46%. Zoophthora radicans hyphal bodies are rod-like to hyphoid, and primary conidia are bullet-shaped to long ovoid. The fungus was isolated from the surfaces of larvae and cultured in Sabouraud dextrose agar with yeast extract (SDAY). The optimal temperature range for mycelial growth was $20{\sim}28^{\circ}C$. Mycelium growth on SDAY supplemented with egg yolk and milk (SDAY-EM) was higher than on SDAY alone. Zoophthora radicans may play an important role in controlling insect population density using naturally induced epizootics.

  • An entomopathogenic fungus, Zoophthora radicans, was found causing epizootics in populations of the green peach aphid, Myzus persicae, on March 27, 1998 at Seongju Gun, Kyungbuk Province in Korea. Anamorhic characteristics of the fungus were described using light and scanning electron microscopy. Distinguishing characteristics of Z. radicans is formation of capilliconidia on a single slender secondary conidiophore.

  • The phytochemical study of the underground parts of Gardenia jasminoides var. radicans Makino (Rubiaceae) led to the isolation of five coumarins. On the basis of spectroscopic evidences, the structures of these compounds were charaterized as ferulic acid(l), 5,8-di-(3-methyl-2,3-dihydroxybutyloxylpsoralen)(2), skimmin(3), uracil(4), $3-0-{\alpha}-D-glucopyranosyl-(1{\rightarrow}4)-{\beta}-D-glucopyranosyloxypeucedanin$ hydrates(5), respectively.

  • In this study, we conducted the anti-HIV-1 enzymes assay in vitro and its active components were predicted by QSAR in silico for the elucidation of action mechanism on anti-HIV of natural resources. The extracts of Gardenia jasminoides var. radicans Makino were tested for their inhibitory effects on the reverse transcriptase (RT), protease and ${\alpha}$-glucosidase. In the enzyme inhibition assay, the methanol extracts of Gardenia jasminoides var. radicans Makino stem showed a strong activity of 32.5% on the enzyme activity to cleave an oligopeptide, resembling one of the cleavage sites in the viral polyprotein which can only be processed by HIV-1 protease. Moreover the methanol extracts of stem exhibited alpha-glucosidase inhibitory activities of 26.1%. The methanol extracts ($100{\mu}g/ml$) of stem showed a weak activity of 13.4% on anti-HIV-1 RT using Enzyme Linked Oligonucleotide Sorbent Assay (ELOSA) method. However, all extracts of leaf and stem didn't exhibit the HIV-1-induced cytopathic effects with IC (inhibitory concentration) of $100{\mu}g/ml$ in HIV-1-infected human T-cell line. From these results, it is suggested that Gardenia jasminoides var. radicans Makino extracts may possibly be involved in the inhibition of reverse transcriptase, protease and alpha-glucosidase but can't vitally concerned with the viral replication in vitro.

  • This study was designed to compare the effects on antioxidant, whitening, and anti-wrinkle improvement of 60% ethanol extracts from Trigonotis radicans var. sericea (TR) and Lactobacillus brevis-fermented T. radicans var. sericea (FTR). The total phenolics contents of TR was 18.6 mg/g, and FTR was 18.2 mg/g. The HPLC analysis confirmed more phenolic compounds were produced in FTR by bioconversion than in TR. The FTR showed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity than TR. The results of the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation decolorization assay, FTR and TR showed higher activity than BHT (positive control). The FTR (1.21-1.29 PF) showed higher antioxidant protection factor (PF) activity than the TR (1.15-1.22 PF) and showed higher tyrosinase, collagenase and elastase inhibitory activities. This results showed L. brevis -fermentation of Trigonotis radicans var. sericea changed the composition profile and has effects on antioxidant, whitening and anti-wrinkle improvement.

  • This study is to find the effective way to green perpendicular wall spaces as soon as possible and to get basic data for activating the perpendicular greening on high story building through the experiment of container-type planting ground in which lightened artificial soil mixed with rock wool was put. Comparative studies of the sizes of containers and soil were carried out but separate management was not performed. Four plants(Euonymus fortunei var. radicans, Lonicera japonica, Parthenocissus quinquefolia, Parthenocissus tricuspidata) which have the capability to cover and screen perpendicular spaces were used in the experiment. In result, a container must be equipped with over 15cm depth soil mixed with less than $30\%$ of rock wool.

  • The objective of this study was to covering of vine the traffic noise barrier and analyse of their growth characteristics. For the purpose of the experiments, chosen were 28 plants. In January 1996 to December 1998, the nursery seedbeds on the Chonju Arboretum in Korea Highway Corporation were seeding and cutting with those species, and a few species were carried out Honam Highway field experiments. The results are summarized as follows ; The germination ratio of seedbed experiments were Wisteria floribunda(88%), Lonicera japonica(86%), Parthenocissus tricuspidata, Paederia scandens(85%), Celastrus orbiculatus(76%), Clematis terniflora var. denticulata(52%), Clematis mandshurica(44%) respectively. The rooting ratio of cutting experiments were Trachelospermum asiaticum var. intermedium(88%), Parthenocissus quinquefolia(87%), Trachelospermum asiaticum var. asiatica(85%), Kadsura japonica(82%), Hedera rhombea(81%), Euonymus fortunei var. radicans(83%), Trachelospermum jasminoides var. pubescens(80%), Lonicera japonica cv. Aureo-reticulata(80%), Trachelospermum asiaticum var. majus(78%), Euonymus radicans cv. Aureo-marginata(66%), in descending order. As a conclusion, this study shows that the traffic noise barrier was effected by Paederia scandens, Lonicera japonica, Parthenocissus quinquefolia, Wisteria floribunda, Parthenocissus tricuspidata in the field experiments and the others were necessary to maintainable management.

  • "SaCheolNaMu" has been used as a Korean folk medicine for the jaundice, lumbago and uterine diseases. Although a crude drug related to this folk medicine is sold in traditional herbal market, the botanical origin of this drug has not been pharmacognostically confirmed yet. In this study, the morphological and anatomical characteristics of the stem of Euonymus species growing in Korea, i.e. Euonymus japonica and E. fortunei var. radicans were studied to clarify the botanical origin of "SaCheolNaMu". As a result, it was found that these two species could be discriminated by the morphological criteria such as the thickness of cuticles, the number of collenchyma cell layers, and the frequency of druse and resinous substance. According to these criteria, it was elucidated that the commercial folk medicine "SaCheolNaMu" was the stem of E. japonica. Meanwhile, HPLC-DAD analysis on the 70% ethanolic extracts of two species showed significantly different HPLC profiles each other. The molecular ions of three characteristic peaks shown in the chromatogram of two species were identified by ESI-MS, and their structures were estimated to be flavonol glycosides.
