In the present study, the anti-oxidative properties of 80% ethanol extracts from 140 kinds of natural plants were investigated. Persicaria perfoliata had the highest anti-oxidative relative potency(VitaminE,
=1.0), followed by Sorbaria sorbifolia var. stellipila, Rosa multiflora, Lysimachia vulgaris var. davurica, Quercus aliena, Quercus mongolica and Lespedeza bicolor (
1.50). Among them, the anti-oxidative activity values of the n-hexane,
, EtOAc, n-BuOH, and water fractions of the 80% EtOH extracts of P. perfoliata and S. sorbifolia in the ORAC assay system were
, respectively, with marked anti-oxidative activity in the ethyl acetate fraction from selected the 2 plant extracts.

We investigated the antimicrobial activity of ether and ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi used as Injin. The antimicrobial activity of the ethylacetate fractions from Artemisia capillaris and Artemisia iwayomogi for tested microbes were stronger than those of ether fractions of the two Artemisia plants. The antimicrobial activity of fractions of Artemisia iwayomogi was higher than that of fractions of Artemisia capillaris for the tested microbes. The extracts of young shoots and leaves showed stronger antimicrobial activity than those of young leaves. The range of minimum inhibitory concentrations(MICs) of ethylacetate fractions from the part of Artemisia capillaris and Artemisia iwayomogi were 0.25~2.0 mg/ml. The MICs of ether fractions were showed higher concentration than those of ethylacetate fractions. The fractions of Artemisia iwayomogi showed lower MICs than fractions of Artemisia capillaris. The highest total polyphenol content was found in young shoots and leaves of A. capillaris. The young shoots and leaves of the two kinds of Artemisia plants showed higher content of total polyphenol.

This study was for developing leaf chlorophyll mutant cultivars of Cymbidium goeringii by ethyl-methanesulfonate(EMS) treatment. Chlorophyll mutant rhizomes were easily produced by 0.2% EMS treatment in this genus. Among the mutants, they became dark brown about 50% of the rhizomes. When the dark-brown rhizomes were cultured in a solidified MS medium, new rhizomes were formed from part of the old ones. Chlorophyll mutant rhizomes were obtained from subcultured meristem tissues of newly-formed rhizomes. The rhizomes were cut and subcultured for a year and then became mutant plants. As the results, they produced 4 kinds of leaf mutant cultivars; zigzag-striped, comb-striped, net-striped, and dwarf types, indicating that the EMS treatment in the rhizome could produce versatile leaf chlorophyll regulating mutants. These results suggest that our method is useful for developing leaf mutant cultivars of this planta which they are estimated as higher commercial values.

In order to screen the functional constituents from nature resource, we studied the bioactivities of methanol extract of the Liriodendron tulipifera branch(MLT). The total phenolic and flavonoid contents, DPPH radical scavenging capacity, reducing power,
chelating ability, inhibition of lipid peroxidation and cell toxicity of MLT were investigated in this study. We found that the total phenolic and flavonoid content of MLT is 75.34 mg gallic acid/g and 20.15 mg quercetin/g respectively. MLT exhibited the antioxidant activity on DPPH radical with a
/mL, the absorbance is 0.388 at
/mL in reducing power assay, MLT prevented 38.56% lipid peroxidation at
/mL. Furthermore, MLT exhibits the potent anti-proliferative activity which inhibited 56.94%, 35.73% growth of HT-29 and Hela cell at
/mL respectively. It showed that the antioxidant activities of MLT were correlated with its total phenolic and flavonoid contents. However further study need to be exploring in the future.

DOI : 10.7732/kjpr.2011.24.1.030
This study was conducted to investigate the antioxidative activity and cytotoxicity of fermented Allium victorialis extract. The results were as follows; The total polyphenol content of A. victorialis extract was 2.63 mg/g, and that of fermented A. victorialis extract was 1.65 mg/g which decreased a little by fermentation. The total flavonoid content of A. victorialis extract was 57.77 mg/g, and that of fermented A. victorialis extract was 62.27 mg/g, and this could increase a little from fermentation. Electron donating ability of A. victorialis extract was lower than vitamin C(97.71%), but before fermentation it was 82.29% and after fermentation it became 82.40%. Nitrite scavenging ability of A. victorialis extract before and after fermentation showed lower numerical value than that of butylated hydroxytoluene(BHT) at pH 2.5 but that of A. victorialis extract expressed higher than that of BHT. Superoxide dismutase-like activity showed relatively low level, 15%. Nitrite production increased by A. victorialis extract but was inhibited after fermentation. Methyl diamphetamine (MDA) content was inhibited with increased concentration of A. victorialis extract compared with
treatment but there was not any difference before and after fermentation. Therefore, production of lipid peroxide(LPO) was inhibited by A. victorialis extract. Cell viability of fibroblast cell was tend to slightly decrease with increased concentration of A. victorialis extract, but not different with control.

This study was performed to analyze the possibility of using Korean native Aster koraiensis Nakai for phytoremediation at various fields. A. koraiensis was cultivated at paddy, upland and forest soils contaminated with heavy metals. After 8 weeks of cultivation, and growth and its absorbing capacity of heavy metals were analyzed. The results showed that A. koraiensis was grown well even at the soil highly contaminated with heavy metals, which means it has a tolerance to heavy metals. As analysis results of arsenic, cadmium, copper, lead and zinc contents absorbed from various soils contaminated with heavy metals, heavy metal absorbing capacity of A. koraiensis was depending on the heavy metal contents in the soils and soil property. In case of arsenic, cadmium and copper, heavy metal accumulation capacities of Aster koraiensis were much influenced by contents of heavy metals in the soils. Absorbing capacity of plants was increased when heavy metal contents in the soils were high. Lead absorbing capacity was depending more on soil property than lead contents in the soil, and was great at sandy soil of forest. Zinc absorbing capacity was influenced by both soil properties and Zn contents in the soil, was increased at paddy soil contaminated with high concentrations of heavy metals and upland soils. In general, A. koraiensis had a tolerance to heavy metals and showed great absorbing capability of heavy metals. So A. koraiensis can be used as a good landscape material for phytoremediation at various soils contaminated with heavy metals.

To investigate effects of Ixeris dentata EtOH ext. on lowering lipid levels and anti-oxidation activity, hyperlipidemic rats were treated with Ixeris dentata EtOH ext. and lipid levels and anti-oxdation activity were measured. The Ixeris dentata EtOH ext. groups showed low concentration of plasma FFA, plasma triglyceride, plasma total cholesterol, and plasma LDL-cholesterol compared to control group. However, concentration of plasma HDLcholesterol was not significantly different among all the treatment groups. The Ixeris dentata EtOH ext. groups showed lower level of liver total cholesterol, liver triglyceride, plasma TBARS, and liver TBARS than those of control group. The Ixeris dentata EtOH ext. groups also showed higher level of GSH-Px activity, SOD activity, and CAT activity than those of control group. Moreover, the Ext. showed lower level of TNF-
, Apo-B, Apo-E, and leptin expression than those of control group. The results in this study shows that the Ixeris dentata EtOH ext. have positive effect in lowering lipid level, and anti-oxidative activity.

Loperamide-induced constipation reduced gastric emptying, small-intestinal and colonic motility, and these effects were prevented by Actindia chinensis(Gold Kiwi Fruit, GKF). In this study, the effects of Actindia chinensis on constipated male Sprague-Dawley rats induced by loperamide(2 mg/kg, s.c.,5 days) were investigated. Rats were randomly assigned to the normal control rats(regular diet), constipated rats(regular diet plus loperamide), constipated rats treated with 2.5% GKF(regular diet supplemented with 2.5% GKF plus loperamide), constipated rats treated with 5% GKF (regular diet supplemented with 5% GKF plus loperamide). There was less fecal excretion and lower fecal water content in loperamide-treated rats than in control rats. Oral administration of GKF blocked the decrease of fecal excretion and fecal water content in the loperamide-treated rats. Mucus production of crypt cell and mucus contents at fecal and mucosa surface were reduced by loperamide-treated rat. But colonic crypt cell contained increased mucin in the GKF treated group and mucus layer stained with alcian blue was significantly thicker in GKF treated rats compared with in loperamide-treated rats. In isolated rat ileum, loperamide produced inhibition of ileal motility. Pretreatment with methanolic extracts of GKF in isolated rat ileum prevented inhibition by loperamide. These findings indicated that the GKF was effective for alleviation of inhibition of colonic peristalsis by loperamide and that GKF might be of value in the prevention of constipation.

This study was conducted to investigate the variation of cone, seed and germination characteristics among populations and among individuals within populations of Picea jezoensis(Siebold & Zuccarini) Carriere distributed in Korea. Cone collected from 25 trees in two natural populations(Mt. Jiri and Mt. Dokyu) and their thirteen cone and seed characteristics as well as three germination behaviors were analyzed. Statistical analysis showed significant differences among populations and among individuals within populations in 9 traits except for seed breadth, seed weight, index of seed wing and mean germination time. Generally, morphological variation of cone and seed wings from Mt. Jiri population has smaller and longer than those of Mt. Dokyu population. Percentage of sound seeds and Tetrazolium test from Mt. Jiri population showed 1.79 and 1.87 higher values than Mt. Dokyu population, respectively. The maximum germination percentage was obtained at the optimum temperature of
and in this case, mean germination time and germination rate showed 7.5 days and 2.9 ea./day, respectively. In seed germination behaviors, percentage(40.7%) and rate(0.90 ea./day) of germination in Mt. Jiri population were more higher and faster than those of Mt. Dokyu population(17.7%, 0.37 ea./day). According to correlation analysis, P. jezoensis populations with small restricted distribution may have been reduced because seed qualities were correlated with increased levels of inbreeding and disproportion flowering.

Shallot is a foreign crop introduced from France in 1995 as a new overwintering field crop with an aim to develop as an export crop. This study was conducted to investigate the effect of nitrogen fertilization level and time of supplementary nitrogen fertilization on growth and development of shallot, and to suggest to several problems raised during introductory trial cultivations. Optimum amount of nitrogen fertilization for bulb yield was 24 kg per 10 a. The best time of supplementary fertilization was February and March, with an equal amount in each month. The inorganic element composition of the harvested bulbs was not significantly affected by N fertilization level or by time of supplementary nitrogen fertilization.

We investigated inhibitory effects of ginseng extracts against compound 48/80-induced responses in rat peritoneal mast cells. Initially, we optimized extraction condition with various temperature and time for recovery of high saponin contents in extracts. Using a primary rat peritoneal mast cells, we examined whether ginseng extracts inhibit compound 48/80-induced histamine release form rat mast cells. High red ginseng-spercific saponin containing extracts were recovered at
for 48 hr, and had no cytotoxicity with relatively high dose of extracts on rat peritoneal mast cells(<0.5 mg/ml). For examine of ameliorate effects of mast cells responses by ginseng extract, we pre-treated the extracts or saline to mast cells and treated compound 48/80. In results, compound 48/80 treatment was increased histamine release (approximately 30%) from mast cells than normal group, whereas ginseng treatment was completely inhibited histamine release. These results suggested that ginseng extracts inhibits the compound 48/80-induced mast cell activation, and ginseng extracts is a candidate for effective therapeutic tools of allergic diseases.

The objective of this study was to determine the effect of antioxidant enzyme activity and radical scavenging activities of thirteen kinds of natural plant pigments. The analytic method of antioxidant activities were measured by estimating DPPH free radical scavenging and nitrite scavenging ability activity. The free radical scavenging activity by method using stable free radical DPPH was the highest in the red cabbaged pigment. Addition of ethanol extract 1mg/ml from onion peel pigment displayed remarkable effect on nitrite scavenging ability about 91.9%. Antioxidative enzyme activity was evaluated in terms of superoxide dismutase(SOD), catalase(CAT), and ascorbate peroxidase(APX) activity. The bitter melon pigment had the highest SOD activity of 87.3%. The activities of CAT and APX were higher in the mulberry leave pigment compared with other natural plant pigments. In contrast, CAT activity of plant pigment samples were unaffected. These results suggest that natural plant pigment had the potent biological activities such as antioxidant enzyme activities, and that their activities exhibited differently depending on each kind of pigments.
