In this study, we investigated the antioxidant activities, inhibition activity against ACE (angiotensin converting enzyme) and antitumor activity of extract from Acanthopanax senticosus HARMS fruits for development novel functional resources. In order to understand the factors responsible for the potent antioxidant and antihypertensive ability of fruits in A. senticosus, it has been evaluated for anti-oxidative activity using Fenton's reagent/ethyl linoleate system and for free radical scavenging activity using the l,l-diphenyl-2-picryl hydrazyl free radical generating system. The fruits extract of A. senticosus showed higher antioxidant activities than positive control,
-tocopherol at all concentrations, while fruits extract of A. senticosus showed same degree of radical scavenging activity with positive control,
-tocopherol. The ability of fruit extracts from A. senticosus to influence the inhibitory activity of angiotensin converting enzyme (ACE) and xanthine oxidase (XOase) has also been discussed. The activity of growth-inhibitory of fruit extracts of A. senticosus was screened by SRB (sulphorhodamine B) method on diverse cancer cells representing different types of cancers. The fruit extracts of A. senticosus showed moderate inhibition on proliferation of LNCaP and MOLT-4F cells and did not inhibit the proliferation of other cancer cells. The fruit extracts of A. senticosus inhibited the proliferation of cancer cells with
values ranging from 5 to
. This result revealed that the fruit extracts of A. senticosus was expected to be good candidate for development into source of free radical scavengers, antihypertentive, and anti-tumor agent.

Dwarfuess and Kunitz trypsin inhibitor (KTI) protein in soybean is useful traits for basic studies. df2 and ti gene control dwarfness and the expression of Kunitz trypsin inhibitor (KTI) protein in soybean, respectively. The objective of this research was to verify genetic linkage or independent inheritance of df2 and ti loci in soybean. The
population was made by cross combination between "Gaechuck#2" (Df2Df2titi genotype, KTI protein absence and a normal growth type) and T210 (df2df2TiTi genotype, a dwarf growth type and KTI protein present). A total of 258
seeds were analyzed for the segregation of KTI protein using SDS-PAGE. And so, 198
plants were recorded for the segregation of dwarfness. The segregation ratio of 3 : 1 for Ti locus (201 Ti_ : 57 titi) and Df2 locus (143 Df2_ : 55 df2df2) was observed. Segregation ratio of 9 : 3 : 3 : 1 (116 Ti_Df2_: 44 Ti_df2df2: 27 titiDf2_: 11 titidf2df2) between df2 gene and ti gene was observed (
=3.53, P = 0.223). These results showed that df2 gene was inherited independently with the ti gene in soybean.

Resveratrol has been associated with reduced cardiovascular disease and reduced cancer risk. This phytochemical has been reported in a number of plant species including grapes, peanuts and pine trees in response to stress such as fungal infection, heavy metal ions or UV irradiation. The objective of this study was to determine the resveratrol contents in leaves of mulberry varieties at different collecting times. Quantitative analysis of 16 cultivars showed a range of
on dry weight basis (which is equivalent to
on fresh weight basis). Resveratrol contents in mulberry leaves was higher in autumn than spring, and higher in fully matured leaves than in juvenile leaves. Among the tested samples, 'Kaeryangppong', 'Sugeppong' and 'Cheongilppong' collected in the middle of October showed high resveratrol contents of
on dry weight basis, respectively. Especially mulberry leaves dried in the shade showed of
on dry weight basis in resveratrol content, this result may contribute to utilization of mulberry leaves.

Soy sprout is a traditional food in Korea. It has been a source of protein, lipid and vitamin etc. as cooked and fresh vegetable supplying throughout the year. Soy sprouts of five soybean cultivars were analyzed fatty acid composition and dietary fiber contents. The compositional analysis confirmed that soy sprout contained five major fatty acids(16:0 palmitic, 18:0 stearic, 18:1 oleic, 18:2 linoleic and 18:3 linolenic). Fatty acid levels in soy sprout were not significant statistically between fresh and boiled soy sprout, the result support a conclusion that boiling treatment could not affect the fatty acid composition in soy sprouts. Fatty acid levels in whole and cotyledon part of soy sprout were not changed during sprout production, whereas the content in hypocotyl increased by approximately 13.2% of total unsaturated fatty acid compared to whole soy sprout. In case of dietary fiber, boiled soy sprouts showed higher contents than in fresh soy sprouts. These changes were associated with an increase in the mean level of insoluble dietary fiber expecially. Fatty acid levels and dietary fiber contents varied with soybean cultivars suggesting chemical composition of soybean seed was important to soy sprout characters.

Thirty five isolates of Trichoderma species collected from seven different locations of Bangladesh were studied for morphological characters and molecular variation. Mycelial diameters of the isolates varied from 8.28 cm to 9.00 cm. Based on colony colour, isolates were grouped into five such as dark green, green, light green, yellowish green and whitish green. Maximum isolates were green and light green. On the basis of growth habit and colony consistency, the isolates were categorized into three groups, in which most species had fast growth and were compact in appearance. PCR-based Random Amplified Polymorphic DNA (RAPD) technique employing 3 decamer primers produced 36 scorable bands of which all (100%) were polymorphic. The co-efficient of gene differentiation (Gst) was 1.0000 reflecting the existence of high level of genetic diversity among the isolates. The Unweighted Pair Group Method of Arithmetic Means (UPGMA) dendrogram constructed from Nei's (1972) genetic distance produced 2 main clusters (13 isolates in cluster 1 and 22 isolates in cluster 2). The result indicating their genetic diversity has opened new possibility of using the most efficient and more isolates of Trichoderma in the preparation of biopesticide and decomposition of municipality waste.

The bio-degradable transplanting pot containing rice by-product (rice-hull and rice-bran) were developed, and tested their ability for agronomic use. Rice by-products were crosslinked with biodegradable aliphatic ally aromatic copolyesters or urea resin for making transplanting pot. Mechanical properties and degradability of these pots were measured and compared to those of the Jiffy pot (commercially used bio-degradable pot). Mechanical strength was higher than that of Jippy pot, and bio-degradability was excellent under the actual field condition. In addition, the pot could be degraded within 3 months under the ground. Our result indicated bio-degradable pot containing rice by-products has a great potential for such agronomic use.

This study was designed to investigate variation of pinitol content in different parts of seventeen legume species including silk tree (Albizia julibrissin). D-pinitol has been demonstrated to exert insulin-like and anti-inflammatory effects. These legumes were collected from Gyeongsangbuk-Do in Korea. Significant difference in pinitol content was observed among 17 different legume species. However, it was the highest in sericea lespedeza (Lespedeza cuneata). The highest pinitol content was observed in leaf followed by stem, pod shell, seed and root among plant parts. Legume plants which had higher pinitol content in leaves were chinese pea shrub, bastard indigo, wild cowpea and sericea lespedeza, having 59.9 mg/g, 62.2 mg/g, 69.6 mg/g and 65.4 mg/g, respectively. Stem of astragali radix showed the highest pinitol content among all leagumes, which was 34.0 mg/g. In case of root, kudzuvine showed the highest pinitol content followed by licorice and chinese pea shrub, which were 24.6 mg/g, 16.9 mg/g, and 16.5 mg/g, respectively. However, in the case of pod shell and seed, only lablab purpureus and sericea lespedeza showed the highest pinitol content 52.5 mg/g (for pod shell) and 24.9 mg/g (for seed), respectively. Concluding, the sericea lespedeza showed the highest total pinitol content of whole plant followed by chinese redbud, chinese pea shrub, bastard indigo and silk tree. Considering the pinitol content and harvesting yield, sericea lespedeza can be used as a practical medicinal herb.

Changes in food preferences and dietary habits of Korean prone to decrease consumption of the traditional energy source, rice. The exceeding condition of rice production in Korea is now not only impacting on the profit structure of farmers but also threatening food security. Although there have been several efforts to increase rice consumption rate, by developing various processed foods using rice flour, grain hardness of rice has been the most significant limiting factor. In this study, we addressed the suitability of the Namil(SA)-flo1, a mutant rice line has floury endosperm, in terms of producing rice flour by using dry-milling method, which is lower cost and more eco-friendly than other available methods such as wet-milling. Rice flour of the Namil(SA)-flo1 exhibited superior physico-chemical characteristics to any other check varieties including the wild type, Namil, in terms of distribution of granule sizes and content of damaged starch.

Health beneficial properties of soybean [Glycine max (L.) Merr.] isoflavones are well known. The objectives of this study were to determine and compare the isoflavone composition and concentrations of soybean varieties grown in different cultivated regions of Vietnam (i.e., upland and lowland). Total and individual isoflavone composition and concentrations were determined by high-performance liquid chromatography (HPLC). Total isoflavone concentrations varied from 1153 to
across environments and varieties. In the lowland region, the highest total isoflavones concentration was observed in M103 cultivar (
) and the lowest in VX9-3 (
), whereas in the upland region the highest and lowest concentrations were in M103 (
) and DT93 (
), respectively. Across varieties, average total isoflavones concentration was higher in the upland than lowland region (3728 vs.
). The malonylglucosides and acetylglucosides concentrations in upland soybean varieties were higher than those from the lowland region. Despite the presence of Genotype (G) x Environment (E) interactions, varieties with consistently high (M103) and low (VX9-3, DT93) isoflavone concentrations across environments were identified. This is the first report of isoflavones in Vietnamese soybean varieties, revealing large variation in isoflavones concentration and profile among different varieties and cultivated regions. Results will be useful in selecting high-isoflavones soybean varieties for growth in tropical regions.

Here we report a simple screening system using hematoxylin staining (HS) of the root apex. It allowed rapid classification into different aluminum (Al) tolerance from 65 cultivars within one week. Using this system, we selected the most Al-tolerant (Jayae-2) and-sensitive (Pum-2) barley (Hordeum vulgare L.) The results show that the different responses in Al-induced growth inhibition, Al accumulation and expression of plasma membrane (PM)
-ATPase in root apices of selected two cultivars. It showed strongly Al-induced growth inhibition in a dosedependant manner only in Pum-2 but not in Jayae-2. Aluminum accumulation in root apices (10 mm) was significantly higher in Pum-2 only. The
-ATPase expression of PM vesicles by western blotting was decreased in Pum-2 but not in Jayae-2 treated with
Al for 24 h. These finding indicate to screen from our system is rapid and reliable and to sustain the expression of PM
-ATPase at translational level is an important role in root growth as affected by Al.

Panax ginseng has been used as a traditional medicine for several centuries in Korea. A laboratory experiment using methanol extracts of freeze-dried leaves and roots in the different ages of P. ginseng was conducted to determine the content of phenolics and flavonoids, antioxidant activity and cytotoxicity. The results indicate that the total phenolics level [mg ferulic acid equivalents (FAE)
DW] was higher in leaves (22.0 to 76.3 mg
) than roots (19.0 to 28.3 mg
) of P. ginseng. The total content of phenolics in roots increased with increase in age of P. ginseng from one to six years. However, the content of phenolics in P. ginseng leaf decreased with the increase in age. Total flavonoid [mg naringin equivalents
DW] was more detected in the leaves (30.3 to 138.6 mg
) than in the roots (0.0 to 10.6 mg
) of P. ginseng. The total flavonoid level in leaves decreased with increase in age of P. ginseng. The antioxidant potential of the methanol extracts from the plants dose-dependently increased. DPPH free radical scavenging activity was higher in leaves (36.9 to 82.8%) than in roots (14.8 to 39.4%), and in young plants than in old ones. According to 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the methanol extracts from 5 year-root part showed the highest cytotoxicity against Calu-6, followed by 2 year- and 3 year-roots. However, the methanol extracts from 6 year- and 4 year-roots had lower cytotoxicity. Total phenolics content in both leaves and roots was highly correlated with the DPPH radical scavenging (
to 0.7870) and nitrite scavenging (
to 0.8794) activities, suggesting that they contribute to the antioxidant properties of the P. ginseng plants.

This experiment was carried out to find suitable sample type for the more accurate prediction and non-destructive way in the application of near infrared reflectance spectroscopy (NIRS) technique for estimation the protein, total amino acids, and total isoflavone of soybean by comparing three different sample types, single seed, whole seeds, and milled seeds powder. The coefficient of determination in calibration (
) and coefficient of determination in cross-validation (1-VR) for three components analyzed using NIRS revealed that milled powder sample type yielded the highest, followed by single seed, and the whole seeds as the lowest. The coefficient of determination in calibration for single seed was moderately low(
0.70-0.84), while the calibration equation developed with NIRS data scanned with whole seeds showed the lowest accuracy and reliability compared with other sample groups. The scatter plot for NIRS data versus the reference data of whole seeds showed the widest data cloud, in contrary with the milled powder type which showed flatter data cloud. By comparison of NIRS results for total isoflavone, total amino acids, and protein of soybean seeds with three sample types, the powder sample could be estimated for the most accurate prediction. However, based from the results, the use of single bean samples, without grinding the seeds and in consideration with NIRS application for more nondestructive and faster prediction, is proven to be a promising strategy for soybean component estimation using NIRS.

Proximate chemical components (protein, oil, carbohydrate, ash, fiber, and starch) were determined from tubers grown in upland and wetland conditions. The contents of crude protein, oil, carbohydrate, and starch were higher in upland condition than in wetland condition. Eight gibberellins were commonly identified and quantified in leaves and tuber of chufa grown in wetland and upland field during growing season. Gibberellin content was always higher specifically in the leaves and tubers grown in wetland condition than in those grown in upland condition. The current knowledge of gibberellin biosynthesis suggests that the two endogenous bio-active gibberellins both
are differently metabolized according to cultural conditions. Major gibberellin biosynthesis route is ascertained dominantly the non C-13 hydroxylation pathway leading
in chufa plants.
