The Opuntia extract has been traditionally used to treat diabetes, inflammation, and rheumatoid arthritis in oriental medicine. The purpose of this study is to investigate characteristics of biological activity between Opuntia humifusa and Opuntia ficus-indica which is cultivating in korea using cell-free system or cell-based assay. O. humifusa extract effectively inhibited
-glucosidase activity or improved the immune function, and its biological activity was more effective than O. ficus-indica extract. The scavenging activity of DPPH radical and the inhibitory effect of tyrosinase similarly showed by O. humifusa and O. ficus-indica extract, however neuroprotective effect only showed a tendency to increase compared with control in PC12 cells. Therefore the results suggest that O. humifusa can be a useful agent for treatment of diabetes and immunodeficiency.

In this study, we investigated the effect of 88 marine algae extracts on melanin synthesis to develop new whitening agents. Among varieties of marine algae tested, the ethyl acetate extracts from Endarachne binghamiae (EB), Scytosiphon lomentaria, Sargassum yezoense, Ecklonia cava and Sargassum fusiforme inhibited melanin synthesis in melan-a cells. EB treatment showed the strongest inhibitory activity in melanin synthesis, compared with that of other extracts. EB-mediated inhibition of melanin synthesis appeared to be associated with inhibition of
-glucosidase-dependent glycosylation of tyrosinase in melan-a cells. In addition, EB treatment did not affect mushroom tyrosinase or cell-extracted tyrosinase activity in vitro. Taken together, our findings suggest that anti-browning effect of EB on skin is mediated through regulation of
-glucosidase activity and subsequent inhibition of tyrosinase activity and melanin synthesis, and further development of EB as a potential agent for skin whitening.

Potatoes were first introduced outside the Andes region four centuries ago, and have become an integral part of much of the world's food. Potatoes were first introduced into Europe in the 16th century and Korea in the early 19th century. In the nutritional aspects, potatoes contain abundant vitamins and minerals, as well as an assortment of phytochemicals such as carotenoids and natural phenols. Chlorogenic acid constitutes up to 90% of potato natural phenols. Due to the high content of potato functional compounds, it has known that potatoes are effective in the prevention of various human diseases. Recently, color-fleshed potatoes 'Hongyoung' and 'Jayoung' were developed by RDA, and it has reported that they have high content of anthocyanin. Additionally they show higher radical scavenging activity compared to white or yellow fleshed potatoes. So it will be expected that the consumption of color-fleshed potatoes grandually increase by pre-peeled potatoes and color potato chips. This study was conducted to enhance the peel of color-fleshed potatoes utilization and to determine the biological activity of peel of color-fleshed potatoes extract. The anti-inflammatory effects on ethanol extract and its solvent fraction were also evaluated. The anti-inflammatory activities of
fraction was evaluated for inhibitory activities against lipopolysacchride(LPS) induced nitric oxide(NO) and prostaglandin
production as well as inducible nitric oxide synthase(iNOS) and cyclo oxygenase-2(COX-2) protein expressions in RAW264.7 cell lines. The fraction inhibitory activity for both tests with
values showed in the ranges of
. This result revealed that
fraction of Jayoung's peel is expected to be good candidate for development into source of anti-inflammatory agent.

This study investigates the change of chemical components, antioxidant and antimutagenic activity in Glycyrrhiza uralensis Fischer stems and leaves (GU) by the various processing methods, as follows: fresh (GU-1), dried under the shade (GU-2), blanched (GU-3), roasted 3 times (GU-4), roasted 4 times (GU-5). The components have been identified and quantified through the use of gas chromatograph-mass spectrometry (GC-MS). At results, cis-1,3-dimethyl-2-methylenecyclohexaneat at 19.7 min and n-hexadecanoic acid at 21.5 min were detected in five kinds of extract. 3-O-Methyl-D-fructose at 17.8 min was observed in four extracts except in GU-1 and aminopyrazine at 19.8min was observed in four extracts except in GU-4. The total phenolics contents was high in GU-4(3.38 g/100 g). ABTS radical scavenging was high in GU-5(
, 0.57 ug) and DPPH radical scavenging was high in GU-4(
, 2.66 ug). The extracts of GU-3, GU-4, and GU-2 were most potent in anti-mutagenicity activity against 1-NP, Trip-P-1, and Trip-P-2, respectively. GU-3 and GU-4 also showed most potent effect of anti-mutagenicity on 2-AA and AFB1, respectively.

The objective of this study was to determine the effect of antioxidant enzyme activity and radical scavenging activities of cucumber grown greenhouse. The analytic method of antioxidant activities were measured by estimating DPPH free radical scavenging, nitrite scavenging ability activity and ABTS radical scavenging ability. The DPPH free radical scavenging activity of Jangjukcheongjang was the highest in most of the growth stage. The Nitrite scavenging ability at pH 1.2 was more than 40% in all cultivars and growth stages. The ABTS radical scavenging ability of Jangjukcheongjang and Nulpureuncheongjang showed relatively little higher than Janghyeongnakhap and Sinjoeunbaekdadagi. The SOD activity showed higher activity than 95% in all cultivars and growth stages. The activity of CAT was highest in the Nulpureuncheongjang of 2 (12~16cm) growth stage, and the APX activity of Nulpureuncheongjang and Janghyeongnakhap showed a relatively high activity. The POX activity showed distinctly different trends depending on the growth stage, and that is, the activity at harvest stage was significantly reduced. These results suggest that the cucumber had the potent biological activities, and that in the future, the availability of cucumber will be increase in the field of high-value cosmetic and food products.

Vaccinium bracteatum Thunb. is an evergreen plant that belongs to the Genus Vaccinium distributed in Korea, and its fruit has been used for food by the common people and thus has a high possibility of commercialization. Therefore, the habitat environment and individual characteristics of V. bracteatum in Jeju Island were investigated to obtain the basic data for commercialization and preservation. The results showed that V. bracteatum is mostly distributed on the southern slope of Mt. Halla at an altitude of 100 to 500 m. V. bracteatum that occurred in the quadrat were total 30 individuals, which had an average height of 6.0 m, an average DBH of 7.8 cm, and an average number of trunk of 4.3. As for the community structure of the habitat, the average percentage of vegetation cover for the tree layer was 36%, while that for the subtree layer was 78%, which emphasized the importance of the subtree layer. The total number of species that occurred in the quadrat was 76. For the tree layer, total 10 species occurred, which include 2 species of evergreen coniferous trees, 3 species of evergreen broad-leaved trees, and 5 species of deciduous broad-leaved trees. For the subtree layer, total 24 species occurred, which include 1 species of evergreen coniferous tree, 11 species of evergreen broad-leaved trees, and 10 species of deciduous broad-leaved trees. Among these, Eurya japonica Thunb. was the species with a high relative contribution, which threatened V. bracteatum For the shrub layer, 27 species occurred including Cinnamomum japonicum Siebold, and for the herbaceous layer, 64 species occurred including Ardisia crenata Sims. The similarity between the habitats of V. bracteatum was very low, and it did not prefer a characteristic community. The V. bracteatum community around Shinrei stream was distributed on the surrounding area adjacent to the slope of the stream rather than the slope. There were a lot of basins, but the branches, which did not receive sunlight, had withered. It is thought that V. bracteatum would decline if the forest formation continues.

This study was conducted to investigate the morphological characteristics of leaf and the genetic diversity of Berchemia racemosa var. magna which is only found in Anmyeon Island of South Korea. ANOVA test showed that there were significant differences among individuals within population in all 10 leaf characteristics. Average characteristics of 39 individuals were 11.8 cm in leaf length, 7.1 cm in leaf width, 1.67 in leaf index, 5.4 cm in upper 1/3 width, 6.2 cm in lower 1/3 width, 3.6 cm in petiole length, 0.19 mm in leaf thickness, 11.5 ea. in number of veins (left), 11.4 ea. in number of veins (right) and 61.7
in leaf area, respectively. Except for leaf thickness (18.8%), petiole length (21.7%) and leaf area (22.0%), the coefficients of variation of most leaf characteristics were relatively low (<15.0%). A total of 50 bands was generated from 8 selected I-SSR primers. The estimates of genetic variation were 1.719 in effective number of alleles (
), 26.0% in proportion of polymorphic bands (P), 0.410 in expected heterozygosity (
) and 0.598 in Shannon's diversity index (S.I.), respectively. In spite of the small number and the limited distribution, the B. racemosa var. magna population in Anmyeon Island showed high genetic diversity.

Deutzia paniculata Nakai is a Korean endemic species that has a very restricted distribution in Gyeongsang-do, South Korea. The genetic diversity and structure of five populations of D. paniculata were investigated using 31 ISSR loci from six primers. The Shannon's index (0.429) and genetic diversity (0.271) were relatively higher than those of other rare plant species in Korea. The Miryang (MY) and Yangsan (YS) populations, which have higher flowering rates than the other populations, showed greater genetic diversity than the other populations. An analysis of the molecular variance (AMOVA) showed that 16% of the total variation could be attributed to differences among the populations, and 84% to the differences within populations, indicating moderate gene flow among adjacent populations. The high genetic diversity and low genetic differentiation in the Deutzia paniculata populations, which have a restricted distribution, is considered to be affected by outcrossing of the mating system and abundant individuals in the populations. These results suggest that ex situ conservation strategies are needed to sustain the current genetic diversity of D. paniculata.

DOI : 10.7732/kjpr.2013.26.5.628
In order to evaluate their potential as sources of biodiesel, oil content and fatty acid composition of seeds and fatty acid methyl ester (FAME) properties from seven woody oil plants in Korea were analysed. The oil content of seed of all woody plant species ranged from 15.1 (Ligustrum lucidum) to 70.3% (Camellia japonica) by dry weight. Fatty acid composition consisted mainly of oleic acid, linoleic acid, linolenic acid, palmitic acid and stearic acid, with oleic acid being the most abundant. The content of unsaturated fatty acids of all species was higher than saturated fatty acids. Oxidation stability of seed oils of all woody plants ranged from 2.25 to 8.62 hours/
. Fatty acid methyl ester of Styrax japonica has been found to have the highest iodine value, indicating that unsaturated fatty acid content is higher than other seed oils. Cold filter plug point(CFPP) was varied over a wide range from
. The cold fluidity of FAME of Chionanthus retusa were excellent.

Korean Journal of Plant Resources, volume 26, issue 5, 2013, Pages 636~644
DOI : 10.7732/kjpr.2013.26.5.636
We examined the effects of soaking, saturation, and aging conditions of raw cowpea seeds, on the yield and growth responses of cowpea sprouts. The absorption caused rapid growth for the first two hours of soaking, then the growth slowed. The longer the soaking period (varied from 1 to 6 hours), the lower the germinability, yield ratio, and lateral root output became. A five-day saturation (moist
) treatment led to higher germinability, yield ratio, and lateral root output than no treatment and one- or three-day saturation treatment. High-temperature aging treatment led to lower germinability and yield ratio compared to no such treatment. Taking these findings into account, the optimal treatment conditions of raw cowpea seeds are a five-day saturation (moist
) treatment followed by cleaning and growing.

DOI : 10.7732/kjpr.2013.26.5.645
The contents of total phenolics and flavonoids, antimicrobial and tyrosinase inhibition activities of five growth stages with four greenhouse-grown cucumber extracts were investigated. Total phenolic content was high in Jangjukcheongjang, Janghyeongnakhap and five growth stage(24~27 cm). The content of total flavonoid did not differ between cultivar or growth stages. Among the four cucumber cultivars, the extract of Janghyeongnakhap showed a relatively strong antimicrobial effect against Staphylococcus aureus. The inhibition zone against Staphylococcus epidermidis of the samples tested in this experiment was 8~12 mm. And the antimicrobial effects against Malassezia furfur was high in Jangjukcheongjang, and showed the highest by the inhibition zone of 14mm in three(17~20 cm) growth stage. The tyrosinase inhibition activity of cucumber extracts showed relatively high activity in Jangjukcheongjang and Sinjoeunbaekdadagi, followed by Janghyeongnakhap. From these results, we confirmed that the extract of cucumber has high antimicrobial and whitening efficacy, and that in the future, the cucumber will be increase the availability in the field of high-value cosmetic materials.

DOI : 10.7732/kjpr.2013.26.5.652
In the present study, anti-oxidative and the RMC proliferation inhibitory propeties of 80% ethanol extracts from 63 kinds of traditional medicines were investigated. Inhibitory effects of RMC proliferation were showed that Dalbergia odorifera T. Chen., Melia azedarach Linn
and Hydnocarpus anthelmintica Pierre. Among them Hydnocarpus anthelmintica Pierre had the highest anti-oxidative activity (
, DPPH = 81.1), but Dalbergia odorifera T. Chen. and Melia azedarach Linn
had no effects. These results suggest that the Hydnocarpus anthelmintica Pierre could prevent or protect from kidney disease as antioxidant and anti-proliferative agent for RMC.

Rubus coreanus and Astragalus membranaceus Bunge have been used as a traditional medicine with various pharmacological properties for a long time in Asia. We investigated the proliferative and differentiative effects on osteoblastic cells, MG-63 in various mixture ratios of immature fructus extracts of R. coreanus and root extracts of A. membranaceus. With preliminary in vivo ovariectomized mice, we confirmed the effects of the supplementation of various mixture on alkaline phosphatase (ALP) activity in serum. The ratio of 7:3 is considered as the most effective ratio for the proliferation of osteoblastic cells as they increased by 56.8% similar to estradiol. ALP activity in osteoblast increased by the combination of R. coreanus and A. membranaceus and peaked in the ratio of 72:28 and 68:32 respectively. These results indicate that the optimal combination of R. coreanus and A. membranaceus in 7:3 has the most beneficial effects on the activation of osteoblast cells, and give further possibilities that it can be used clinically in the treatment of osteoporosis.
