This study was aimed to screen edible herbs which control the composition of intestinal microflora. With in vitro experiments, we screened the water or ethanol extracts of about 60 edible herbs and wild plants in terms of the inhibition activity on the growth of the harmful Clostridium perfringens and growth promoting activity for the beneficial Bifidobacteria. The water extracts of mugwort and small water dropwort inhibited the growth of Cl.perfringens both in agar diffusion method and broth culture. On the other hand, the water extracts of petasites, mugwort, yellow day-lily and bitter cress have shown the promotion effect on the growth of Bifidobacterium longum. In the culture test using human feces as starter, the extracts of the above selected herbs increased the population of Bifidobacteria and Lactobacillus while they reduced the numbers of Cl.perfringens and E.coli.

Various natural compounds act as antioxidants in protection against lipid peroxidation. Lipid peroxidation yields a variety of decomposition products which have been implicated in not only decreasing the nutritional value of food, but also in developing an off-flavor and toxic substances. As a source of safer and more effective natural antioxidants of natural origin have been widely investigated. Some Indonesian plants have evaluated for their antioxidative activity, and suggested the possible existence of various antioxygenic compounds in them. We attempted to study such antioxygenic compounds with simple method evaluation. As we are interested in the natural product compounds, we examined of several sample such as edible sea-weeds, and some edible fruits. Sea-weed, Eisenia bicyclis, one of the edible brown algae, exhibited the activity. As a traditional food additive consumed by Indonesian, Garcinia parvifolia is used as taste supplement in region West Sumatra, have been studied. Our current studies on the semi-polar fractions shows the activity by the thiocyanate method test. Another sample, Garcinia mangostana, a famous fruit with sweet taste, the part kernel have also evaluated. The acidic fraction of the extract showed antioxidative activity. Some other active components were found in the neutral and BuOH fractions.

This study was carried out to elucidate the distribution of vascular plants and their usefulness of Mt. Munsusan (1,205 m) in Bonghwa County, North Gyeongsang Province, South Korea. The vascular plants that were investigated in 2 years (2019 ~ 2020) with 15 times consisted a total of 571 taxa; 94 families, 310 genera, 496 species, 4 subspecies, 63 varieties and 8 formas. For the Korean endemic plants, 17 taxa were recorded and 3 taxa of Vulnerable Species (VU) and 9 taxa of Least Concerned species (LC) categorized by the Korean Forest Service as rare plants were investigated in this region. Furthermore, IV, III degrees of floristic regional indicator plants designated by the Korean Ministry of Environment included 8 taxa and 27 taxa, respectively. Among them, edible, medicinal, ornamental, feed/composting, industrial plants were 391 taxa, 359 taxa, 301 taxa, 241 taxa, 217 taxa, respectively. In addition, 25 taxa of naturalized plants were observed.

This study was carried out in order to catalogue the folk plants of 7 counties and cities of northern region of Chungcheongbuk-do from March to October, 2011. Based on the 626 survey sheets collected from 67 residents at 17 places of 7 counties and were subsequently analysed. The identified folk plants in the northern region of Chungcheongbuk-do consisted of a total 348 taxa; 98 families, 250 genera, 298 species, 5 subspecies, 38 varieties, and 7 forms. The use by its usage were: 223 taxa; edible, 123 taxa; medicinal, 4 taxa; dye, 2 taxa; aroma, 6 taxa; spice, 32 taxa; ornamental, 11 taxa; oil, 4 taxa; starch, 22 taxa; and others, respectively, so the edible use is the highest. The most useful part was the leaf, followed by fruit and root. The consistency comparison between the scientific and the local name were the highest in the 50's and the lowest in 80's.

Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, and Portulaca) of edible plants and the effect of the processing on cyanide concentration. Total cyanide content was measured by ion chromatography following acid hydrolysis and distillation. Kernels of Prunus genus are used medicinally, but they possess the highest level of total cyanide of up to 2259.81 $CN^-$/g dry weight. Trace amounts of cyanogenic compounds were detected in foodstuffs such as mungbeans and bamboo shoots. Currently, except for the WHO guideline for cassava, there is no global standard for the allowed amount of cyanogenic compounds in foodstuffs. However, our data emphasize the need for the guidelines if plants containing cyanogenic glycosidesare to be developed as dietary supplements.

Plant-based vaccines possess some advantages over other types of vaccine biotechnology such as safety, low cost of mass vaccination programs, and wider use of vaccines for medicine. This study was undertaken to develop the transgenic maize as edible vaccine candidates for humans. The immature embryos of HiII genotype were inoculated with A. tumefaciens strain C58C1 containing the binary vectors (V662 or V663). The vectors carrying nptII gene as selection marker and scEDIII (V662) or wCTB-scEDIII (V663) target gene, which code EIII proteins inhibite viral adsorption by cells. In total, 721 maize immature embryos were transformed and twenty-two putative transgenic plants were regenerated after 12 weeks selection regime. Of them, two- and six-plants were proved to be integrated with scEDIII and wCTB-scEDIII genes, respectively, by Southern blot analysis. However, only one plant (V662-29-3864) can express the gene of interest confirmed by Northern blot analysis. These results demonstrated that this plant could be used as a candidated source of the vaccine production.

We have studied the effect of 31 extracts and 10 components from some edible and medicinal plants on the formation of lipid peroxide in the liver homogenate of rat in vitro. The 70% acetone extracts of Allium tuberosum, Beta vulgaris var. cicla and Brassica juncea var. integrifolia, and methanol extract of Capsicum annuum decreased the formation of lipid peroxide by 33%, 58%, 62% and 56% at the concentration of 1mg/ml, respectively. And these four extracts inhibited the lipid peroxidation at the concentration of $10^{-1}$mg/ml by 17%, 46%, 49% and 45% respectively. Among the component tested, quercetin, quercitrin and isorhamnetin reduced the formation of lipid peroxide by 45%, 15% and 28% respectively at the concentration of $10^{-2}$mg/ml.

The plant flavonoids, including apigenin which is found in especially high concentrations in edible plants, are reported to protect against chronic diseases including several types of cancer. We observed that apigenin inhibited not only the growth of human melanoma cell line SK-MEL 28 but also the telomerase activity. We also noted the telomerase activity inhibition by genistein, a tyrosine kinase inhibitor found in soybean, which suggests that the telomerase activity of SK-MEL 28 cells may be regulated by the protein phosphorylation. Furthermore, we observed that apigenin induced SK-MEL 28 cell apoptosis with p53 upregulation. Taken together, our results indicate that apigenin plays a role as an antimelanoma component in edible plants.

The screening of anti-cancer activity for the MeOH extracts of 163 natural sources, which were registered as edible plants by Korea Food & Drug Administration, exhibited 9 extracts to have significant inhibitory effects on farnesyl-protein transferase (FPTase) and phosphatase of regenerating liver-3 (PRL-3). In order to confirm the inhibitory activity of these active extracts, the activity assay was repeated for some fractions obtained from the active extracts using Medium Pressure Liquid Chromatography (MPLC). Some fractions of Carya illinoensis, Chlorella vulgaris, Panicum miliaceum, Perilla frutescens, Rosmarinus officinalis showed over 50% inhibitory activity on FPTase as well as those of Capsella bursa-pastoris, C. illinoensis, C. vulgaris, Coix lacrymajobi, Myristica fragrans, P. miliaceum, R. officinalis did over 50% inhibitory activity on PRL-3.
