  • Antithiamine activities of dried wild vegetables consumed in Korea were evaluated by means of the thiochrome fluorescence and Lactobacillus viridescens bioassay methods and compared with the phenolic content and the degree of browning of the samples. Eggplant, sweet Potato stalk, bracken, red pepper leaf, Aster scaber and mugwort had higher antithiamine activities than Codonopsis lanceolata, doraji, taro stalk, pumpkin, oak mushroom and acorn starch. Wild vegetables with high antithiamine activity tended to have a high phenolic content and degree of browning. It is recommended that wild vegetables should not be cooked with thiamine-rich foods and be eaten immediately after cooking in order to minimize the thiamine decomposition.

  • Oxidant radicals are implicated as a causal factor in the pathogenesis of neurobiological disorders and neuro-degenerative diseases. The objective of this study was to investigate the antioxidant activity of edible plants against oxidative stress in bovine brain tissue. Fifty five kinds of edible plants grown in Korea were dried either by freeze-drying or hot-air drying (7$0^{\circ}C$), and evaluated for their antioxidant activity by measuring TBARS (thiobarbituric acid-reactive substances) in brain homogenates subjected to Fe$^{+2}$_mediated lipid peroxidation with or without the addition of botanical extracts. Heat-drying decreased the antioxidant activity of most plant extracts by 10~81%, compared with freeze-drying. However, Aruncus americanus, Ligularia stenocephala, Artemisia princceps var. orientalis, Petasites japonicus and Aster scaber showed very strong antioxidant activities regardless of processing, with or without heat treatment. The $IC_{50}$/ values of the methanol extracts from these edible plants were in the range of 0.093~0.379 mg/$m\ell$, which was lower than that of ascorbic acid (0.79 mg/$m\ell$). Thermal processing of some edible plants enhanced their antioxidant activity.

  • As science and technology has developed, human could be flourished especially at the aspect of agriculture and medicine. However, the traditional knowledge of them has stopped being used, which leads to extinctions of it. Korea National Arboretum had surveyed the ethnobotanical uses of Gangwon-do from 2006 to 2017. 522 taxa were defined as ethnoplants through 21469 sheets thanks to 355 respondents who composed 279 females, 73 males and three refused to answer. Analysis of ethnoplants had conducted to provide the excavation of the new plants for industries of agriculture and medication, as well as the evidence for protection of TK and benefit derived from it. Aster scaber Thunb. had been found as the most citated taxa by 0.6591 RFC figure, Pinus desiflora Seibold & Zucc. was found to have the extensive categories of use. Aralia elata (Miq.) Seem. showed the highest figure of CI value. In the index of RI, Pinus desiflora Seibold & Zucc. appeared again, as well as CV, cultural value. For evaluation of the usages of ethnoplants IAR figures are analyzed. The fiber has shown the biggest figure of IAR, despite the dyes are placed the smallest figure.

  • The purpose of this study was to evaluate tyrosinase inhibitory activity of plant extracts, especially Korean indigenous plants, for the cosmetic use of skin whitening. When 50 plant extracts were tested, the methanol extracts of Agrimonia pilosa, Aster scaber; Dianthus sinensis, Fatsia japonica, Hemistepta lyrata, Lespedeza cuneata, Osmunda japonicum, Pyrvla japvnica, Rodgersia phodophylla and Veratrum grandiforum possessed the considerable tyrosinase inhibitory activity at 3-300 $\mu\textrm{g}$/mL. Especially, L. cuneata, aerial part of O. japonicum and V. gandiforum exhibited the strong inhibition (>50% inhibition at 300 $\mu\textrm{g}$/mL). In particular, the methanol extract of V. grandiforum and its ethylacetate fraction showed potent inhibition ($IC_{50}$/=30 and 13$\mu\textrm{g}$/mL, respectively), while the reference compound, kojic acid, showed $IC_{50}$/ value of 26$\mu\textrm{g}$/mL. These plant extracts may be used as tyrosinase inhibitors in cosmetics.

  • This study was conducted to estimate the general components, minerals, and dietary fiber contents of Synurus deltoides. S. deltoides contained 81.1% moisture content, and the proportions of crude fat, crude protein, crude ash, and crude fiber were 0.3%, 4.2%, 2.6%, and 3.5%, respectively. Potassium (3,249.1 mg) was the most abundant component among the minerals in S. deltoides. In addition, S. deltoides contained many other minerals, e.g. calcium (854.8 mg), phosphorus (60.3 mg), magnesium (344.7 mg), sodium (57.3 mg), zinc (1.7 mg), iron (30.9 mg), copper (0.8 mg), and manganese (5.8 mg). Almost all of the mineral contents of S. deltoides were higher than those of Aster scaber and Ligularia fischeri, except for zinc, copper, and manganese. Total dietary fiber (TDF), insoluble dietary fiber (IDF), and soluble dietary fiber (SDF) contents of S. deltoides were 42.6 g, 37.9 g, and 4.7 g, respectively, and these were also higher than those of A. scaber and L. fischeri used in this study. These results suggest that S. deltoides may be a valuable nutrient source.

  • This study was carried out to select proper species for early stage replantation in cutting-slope area of the Baekdu Range roadside. In the cutting-slope area and upper forest area of the cutting-slope area, sample plots of 104 were selected and their vegetations and environmental factors were investigated. We found total 151 species in the 104 plots. The species of high frequency of Baekdu Range roadside were found in the order of Lespedeza bicolor, Festuca arundinacea, Eragrostis curvula, Pinus densiflora, Salix hulteni, Lespedeza cuneata, Erigeron annuus, Rubus crataegifolius, Spodiopogon sibiricus, etc. The dominancy of Festuca arundinacea, Eragrostis curvula, Lespedeza bicolor, Pinus densiflora, Salix hulteni, Spodiopogon sibiricus, Miscanthus sinensis, Lespedeza maximowiczii, Acer ginnala were 12.74%, 10.43%, 7.48%, 4.42%, 4.09%, 3.13%, 2.49%, 2.45%, 2.40% in the roadside cutting-slope, respectively. The importance value of Quercus mongolica, Lindera obtusiloba, Rhododendron mucronulatum, Lespedeza maximowiczii, Rhododendron schlippenbachii, Lespedeza bicolor, Quercus serrata, Rhus trichocarpa were 17.32%, 13.82%, 11.60%, 11.31%, 8.76%, 8.04%, 7.65%, 7.10% in shrub layer of the upper forest area, respectively.
