Naturally occurring substances which strongly scavenge peroxynitrite(ONOO-) are evaluated to be beneficial for cardiovascular, diabetic, hypercholesterolemic and obese disease. To search for bioactive substances with peroxynitritescavenging activity from the young leaves of Heracleum moellendorffii(Umbelliferae) used for a mountainous vegetable, the experiment on peroxynitrite-scavenging assay, phytochemical isolation and HPLC analysis were undertaken. Activity-guided fractionation led to the separation of astragalin and hyperoside which were identified by physicochemical and spectroscopic data. The
values of astragalin and hyperoside were shown as
, respectively, in the assay. The HPLC analysis led to the quantitative determination of astragalin and hyperoside by
dried weight, respectively.

Rosa rugosa has been used as a folk medicine with various pharmacological properties for a long time in Asia. Recently, it has been reported that the extract of fractions from different parts of Rosa rugosa have various pharmacological effects on diverse diseases including diabetes, inflammatory diseases and tumor. We investigated effects of fructus extracts of Rosa rugosa(RRF) and semen extracts of this herb(RRS) on macrophage to evaluate the possibilities as a biological response modifier. We showed increased effects on tumoricidal activity, phagocytic activity, TNF-
and NO production in RRF-treated groups without direct tumor cell cytotoxicity. RRS-treated groups increased direct tumor cell cytotoxicity at high dose without tumoricial activity except increasing of TNF-
release. These results provide further possibilities for the beneficial immunomodulating effects of RRF on immune system with relatively larger safety margin rather than RRS.

Antioxidative activity, including inhibitory activities of angiotensin I converting enzyme(ACE), aminopeptidase N(APN) and
-amylase, was investigated in the methanol extracts from Theaceae plants native to Jeju island, in order to select the plant species containing bioactive materials for functional food or medicines. ACE inhibitory activity was above 50% in Ternstroemia japonica(stem bark) and Cleyera japonica(leaf), and APN inhibitory activity was low to be positive only in C. japonica(leaf, stem bark) and T. japonica(stem bark).
-Amylase inhibitory activity was above 30% in Camellia japonica(fruit), Eurya emarginata(stem), T. japonica(stem bark) and Thea sinensis(stem). The antioxidative activity, estimated by the DPPH radical scavenging capacity, was above 30% in C. japonica(stem bark), T. japonica(stem bark) and T. sinensis(leaf). Particularly, the antioxidative activity analyzed by dot-blot test was very high in C. japonica(stem bark) relatively to those of other plants, and remained high in the low concentration(
). From the TLC analysis of antioxidative compounds, EGC(Rf 0.26) was found to have high activity in stem bark of C. japonica and EGCG(Rf 0.09) was found to have high activity in stem bark of C. japonica, E. emarginata, and T. japonica. Five bands (Rf 0.54, 0.46,0.44, 0.16, 0.03) which were not identified as compared with catechins were detected as polyphenolic compounds on the TLC plates sprayed with the Folin-Ciocalteu solution or the Ferric chloride-alcohol solution. These results suggests that Theaceae plants except E. japonica could be potentially used as a resource of bioactive materials for functional foods or medicines and further research is reguired to identify the bioactive substances and determine the functions of them.

Red ginseng(RG, steamed and dried root of Panax ginseng C. A. Meyer, family Araliaceae) and fermented red ginseng(FRG, fermented red ginseng by yeast and lactic acid bacteria) are known to show different pharmacological effects by changed composition of saponins through fermentation. We examined the effects of RG and FRG on
-hexosaminidase secretion, ICAM-1 expression, the mitogen-induced proliferation of lymphocyte from mice in ex vivo systems and HaCaT cell(keratinocyte) proliferation to compare the anti-allergic and anti-inflammatory effects between both groups. RG groups showed inhibition of
-hexosaminidase secretion and ICAM-1 expression at
and the same effects were observed at all concentrations in FRG groups. In our study, RG increased LPS-induced B cell proliferation at
and ConA-induced B cell proliferation at
but FRG decreased LPS- and ConA-induced lymphocytes at
. We showed that FRG increased the proliferation of HaCaT at 1,
but not by RG. These findings suggest that RG and FRG might have anti-inflammatory and anti-allergic effects, which can be needed to proper clinical concentration to applied to various allergic diseases and inflammation.

In this study, we examined the anti-diabetic activity in vitro by the mixed Korean herb water extracts(JDG) composed of Lycium chinense, Cordyceps militaris, and Acanthopanax senticosus on hepatic glucose-regulating enzyme activities such as glucokinase(GK), acetyl-CoA carboxylase(ACC), and inhibition activity of
-glucosidase. The hepatic cytosol fraction of a type II diabetic animal(Goto-Kakizaki rat) was used in GK and ACC activity assays. JDG mixed water extracts significantly increased the hepatic GK and ACC activity. The highest anti-
-glucosidase activity was observed in JDG 5 water extract when compared to the acarbose control, inhibitor of
-glucosidase. We suggest that Lycium chinense, Cordyceps militaris, and Acanthopanax senticosus mixed water extracts may exert an anti-diabetic activity by enhancing the glucose metabolism and may be used as natural
-glucosidase inhibitors in type 2 diabetic conditions.

This study was performed to investigate the antimicrobial effects of Ampelopsis brevipedunculata ethanol-extract on food spoilage or foodborne disease microorganism. The antimicrobial activity of Ampelopsis brevipedunculata extract was determined by a paper disc method. The extract exhibited growth inhibiting activities in a concentration dependent manner on 7 species of microorganisms. The extract of Ampelopsis brevipedunculata showed the highest antimicrobial activity against Escherichia coli O157:H7. The growth inhibitory effects of the extract at the concentration of 250, 500, 1,000, 2,000 mg/L on food poisoning microorganism were determined against Salmonella typhimurium, Yersinia enterocolitica, Escherichia coli O157:H7 and Staphylococcus aureus. The growth of microorganisms was not affected by the extract at the concentration up to 250 mg/L, but was significantly (p<0.05) inhibited by the extract at the concentration higher than 500 mg/L. The results in the present study demonstrate antimicrobial effects of Ampelopsis brevipedunculata ethanol-extract against foodborne pathogens, suggesting that Ampelopsis brevipedunculata could be an effective natural antibacterial agent in food.

Methanol extracts of the aerial and rhizome parts obtained from ten species of ferns has been screened for antimicrobial activities against Bacillus subtilis, Escherichia coli, Listeria monocytogenes, Propionibacterium acnes, Streptococcus mutans and Streptococcus sobrinus. Antimicrobial activities were carried out using broth microdilution method and paper disc diffusion assay and the extracts which showed clear zones more than 15mm in concentration of 2 mg/disc were tested for its antimicrobial activities at the
concentration of each extract for three days. The non-sterilized crude methanol extracts of Osmunda cinnamomea var. fokiensis rhizome showed the highest antimicrobial activities on B. subtilis(39%), E. coli (33%) and L. monocytogenes(58%) at the concentration of
after 72 hours. In P. acnes, frond extract of O. cinnamomea var. fokiensis showed most vigorous antimicrobial activities in the all extracts but it showed weak activity(clear zone diameters below 15 mm). All extracts has the antimicrobial activities on Streptococcus, but they exhibited weak activity. At the concentration of
, only Osmunda japonica rhizome extracts showed 28 and 39% of antimicrobial activities on S. mutans and S. sobrinus after 72 hours and the other extracts showed below 10% of antimicrobial activities on S. mutans and S. sobrinus.

Korean Journal of Plant Resources, volume 23, issue 5, 2010, Pages 445~450
This study was carried out to investigate the antioxidative capacity of Ampelopsis brevipedunculata 95% ethanol extracts. The concentration of A. brevipedunculata extract at which DPPH radical scavenging activity was inhibited by 50% was 0.42 mg/mL as compared to 100% by pyrogallol as a reference. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of A. brevipedunculata extract at the concentrations of 0.1 and 1 mg/mL were 0.65 and 3.71 mM Trolox equivalents, respectively. Oxygen radical absorbance capacities of A. brevipedunculata extract at the concentrations of 5 and
were 22.75 and
gallic acid equivalents, respectively. Superoxide scavenging activities of A. brevipedunculata extract at the concentrations of 0.1 and 1 mg/mL were 27.7 and 56.0%, respectively. Total phenolic contents of A. brevipedunculata extract at the concentrations of 0.5 and 2.0 mg/mL were 0.55 and 2.06 mM gallic acid equivalents, respectively. A. brevipedunculata extract at the concentration of 0.1 mg/mL inhibited 0.2 mM and 0.5 mM tert-butyl hydroperoxide induced cyototoxicity by 36.2 and 23.3%, respectively, in HepG2 cell culture system. Thus strong antioxidant and cytotoxicity-inhibiting effects of A. brevipedunculata extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.

In order to elucidate the antioxidant potential of non-edible parts of oriental melon, antioxidant activities and total phenolic compound contents of six samples including peel, placenta, stem leaf, flesh and seed were determined. Antioxidant activities were evaluated using in vitro DPPH, ABTS, FRAP, and SOD assay. Among non-edible parts of oriental melon, stalk showed the highest antioxidant activity and its antioxidant potential increased significantly in a dose-dependent manner. The contents of total phenolic compound were also higher than other parts. The relationship between antioxidant activities and the contents of total phenolic compound were analyzed and showed higher correlation coefficients between ABTS radical scavenging activity and contents of total phenolic compound. The above results suggest that the stalk of oriental melon may have potential as a good source for functional material.

Twelve garlic cultivars collected from Korea and Mongolia were evaluated genetic similarity and diversity by RAPD method using oligo-nucleotide random primers. Genomic DNA isolated from twelve garlic cultivars were amplified by polymerase chain reaction using 143 primers, and 55 primers showed polymorphic DNA bands. Among a total of 187 bands amplified by 55 primers, 128 polymorphic bands were subjected to analysis for genetic relationship of garlic cultivars. Garlic cultivars were classified into three groups, such as group-I corresponded to Euiseong, Seosan, Samchuk and Yecheon-A, Yechun-B, Euiseong-norang, Jeongsun, Namdo, Yookback and Danyang cultivars, and group-II to Mongolia and group-III to Daeseo cultivars. Thirty DNA bands showing unique specificity to the specific cultivars are likely to be useful for identification of garlic local cultivars as DNA markers.

This study was carried out to classify the regional folk plants in the inland of Gyeongsangbuk-do. According to the survey results from 582 survey sheets of 126 residents at 85 places of 17 counties and cities from March to October, 2009, the folk plants in the inland of Gyeongsangbuk-do consisted of a total 254 taxa; 76 families, 207 genera, 225 species, 2 subspecies, 26 varieties, and 1 form. The use by its usage was: 216 taxa; edible, 82 taxa; medicinal, 30 taxa; dye, 3 taxa; aroma, 4 taxa; spice, 4 taxa; ornamental, 1 taxa; fiber, 2 taxa; oil, 1 taxa; starch, 5 taxa; fuel, 9 taxa; others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by stem and root. The folk plants of 3 head families from Yeongyang and Cheongsong were 42 taxa. The consistency comparison between the scientific name and the local name were the highest in the 50's and the lowest in 80's.

This study reports on the morphological characteristics and distribution for conservation and practical use in the Korean Peninsula of Chrysosplenium flaviflorum through a comparison with relative species. The morphological characters that were newly investigated in this study included subhypogaeus stolons and glabrous on the surface of leaves. The former has not been described by any taxonomist who had previously treated this species with the exclusion of Hara. Despite this, the latter is a very important key to using the identification of varieties of Ser. Pilosa though there were no descriptions which included Ohwi. C. flaviflorum Ohwi which was endemic and known to be distributed only in the northern area of the Korean Peninsula, was also observed in the Gapyeong-gun, Gyeonggi-do, Cheorwon-gun, Gangwon-do, and Yeongdonggun, Chungcheongbuk-do middle area since the latest collection report in 1943. There is a requirement for further study to be conducted on the distribution and management by designation for the Special Plant Species by the Korean Ministry of Environment.
