  • The aim of this study was to investigate the flora and distribution of evergreen plants in Busan from February 2003 to September 2004. A total of 68 evergreen plant taxa belonging to 33 families, 51 genera, 60 species, and 8 varieties were recognized in Busan. 9 species was included in evergreen plant taxa such as Akebia quinata, Rosa wichuraiana, Osmanthus heterophyllus, Lonicera japonica, Lonicera japonica var. repens, and Carex boottiana. In the forests of evergreen, the canopy consisted of tall trees such as Pinus thunbergii, and understatum trees such as Eurya japonica, Elaegnus macrophylla, and Euonymus japonica. Herb layer consisted of Rubus hirsutus, Hedera rhombea, and Trachelospermum asiaticum var. intermedium. In addition to evergreen plant communities, the patchy spaced communities occurred Neolitsea sericea-Cinnamomum japonicum community, Ficus erecta community, Hedera rhombea-Trachelospermum asiaticum var. intermedium community, Ardisia japonica community, Gleichenia dichotoma community, and G. Japonica community. For rate of appearance of species in 23 sites, 13 species was appeared more than 50% and 29 species less than 10%. There was marked a decrease in the number (density) of evergreen according to the geographic distances from seaside to inland.

  • This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Lonicera japonica Thunberg (LLJ) on proliferation of the cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180) and antiallergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LLJ extract showed higher antiproliferating effect than that of LJ (Lonicera japonica Thunberg) extract. In an anti-cancer testing using Hep3B cells, LLJ extract showed growth-inhibitory effect of $85.60{\pm}4.66%$ at 3mg/rnL. In an anti-cancer testing using MCF-7 cells, LLJ and LJ extracts showed high antiproliferating effect. LLJ showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 61% for LLJ, 37% for LJ. LLJ inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa) and S-180 tumor, and will be beneficial in the treatment of allergic reaction.

  • Objective : Gastritis is a major complication of gastrointestinal disease. Lonicera japonica is used in folk medicine to treat different diseases such as exopathogenic wind-heat, epidemic febrile diseases, sores, carbuncles and some infectious diseases. Therefore, this study examined the effects of Lonicera japonica water extract (LJE) on HCl/ethano-linduced acute gastric ulceration and anti-oxidants properties. Methods : LC-ESI-IT-TOF MS was employed for rapid identification of major compound from LJE. The antioxidant activities were evaluated through total polyphenol and flavonoid contents and radical scavenging assays and superoxide dismutase (SOD)-like activity. SD rats were randomly divided into five different groups including the normal group, ulcer group, positive group (20 kg/mg of omeprazole, ip), and experimental groups (100 kg/mg and 500 kg/mg of LJE, ip). Results : 4,5-Dicaffeoyl quinic acid, loganic acid, secologanic acid, sweroside, loganin, vogeloside were identified based on the detection of the molecular ion with those of literature data. The LJE was possessed free radical scavenging activities such as DPPH (IC50=189.7 ㎍/㎖), ABTS (IC50=164.5 ㎍/㎖), and SOD-like activity (IC50=405.02 ㎍/㎖). Macroscopic and histological analyses showed LJE treated group were significantly reduced to an extent that it allowed leukocytes penetration of the gastric walls compared with the ulcer group. In addition, an ulcer inhibition rate and prostaglandin E2 levels were increased in rats treated with LJE. Conclusion : The present study has demonstrated the antioxidantive and gastroprotective effect of LJE, these findings suggested that LJE has the potential for use in treatment of gastric disorders.

  • Fourteen compounds were isolated from the 70% ethanol extract of Lonicera Caulis (Caprifoliaceae) and their structures were identified as seven aliphatic compounds [long-chain alcohols (1, 2), trilinolein (3), hexacosanol (4), fatty acids (6), 9,12,13-trihydroxyoctadeca-10(E),15(Z)-dienoic acid (10), and pinellic acid (11)] and seven phenolics [bis(2-ethylhexyl) phthalate (dioctylphthalate, DOP) (5), coniferaldehyde (7), caffeic acid docosanoyl ester (8), caffeic acid (9), coniferyl aldehyde 4-O-glucoside (12), linarin (13), and coniferin (14)]. The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. All the compounds except for caffeic acid (9) were isolated from this plant parts for the first time.

  • In this study, we attempted to obtain an active ingredient that inhibits the production of matrix metalloproteinase-1 (MMP-1) that breaks down collagen in human skin fibroblasts. More than 50 plant extracts were screened, and Lonicera japonica was selected for this study. The stem of L. japonica was extracted with 70% ethanol and fractions with solvents in the order of hexane, ethyl acetate, and butanol. MMP-1 production were significantly inhibited at the concentration of 50 ㎍/mL of the ethyl acetate layer and 200 ㎍/mL of the butanol layer. To get a fraction containing all of these effective components, 80% ethanol fraction (LJ F80) was obtained through HP20 resin column chromatography. The reference substance, loganin and LJ F80 inhibited dose-dependently MMP-1 production. At the same concentration, LJ F80 showed a higher inhibitory effect than loganin. The stability of this fraction was analyzed with HPLC while kept storing at 4 ℃, room temperature, and 40 ℃, for 16 week. The stability was maintained as ± 10% of initial value with reference loganin. Therefore, it is thought that LJ F80 of L. japonica may be used to improve wrinkles.

  • The objective of this study is on suggesting the simulation model of 10 selected plants for the traffic noise barrier through field experiment by computer. The field experiment was carried out at the traffic noise barrier of Honam highway. The results are as follows. 1. It was identified that Paederia scandens, Celastrus Orbiculatus, Lonicera japonica, Wisteria floribunda, Parthenocissus tricuspidata and Parthenocissus quinquefolia grows well vertically and takes 3 years in covering completely. 2. It was identified that Trachelospermum asiaticum and Hedera rhombea, evergreen Climber(vine), grows slowly in comparative with other deciduous Climbers(vine), but give drivers good landscapes in winter. So those have considerable value in the south region of Taejeon. 3. It was identified that Wisteria jl.oribunda, Lonicera japonica, Paederia scandens, Clematis mandschurica and Campsis grandijlora showed good view in flowering period. 4. It was identified that auxiliary materials for inducing growth were needed in other plants except Parthenocissus tricuspidata, Parthenocissus quinquefolia. 5. It was identified that subsequent research about the auxiliary materials for inducing growth and adequate planting distance of each plants is needed for actual application.
