신수철 한국농화학회 1988 Applied Biological Chemistry (Appl Biol Chem) Vol.31 No.3

For the effective utilization of Wild Korean lettuce(Youngia sonchifolia Max.), the chemical characteristics, contents of free sugar, amino acid composition, fatty acid composition and minerals were analysed. Free sugars determined from the roots were rhamnose, frucrose glucose, sucrose maltose. melibiose and raffinose, whereas raffinose was not detected from the leaves. Of amino acid composition in the roots glutamic acid content was largest followed by histidine aspartic acid, leocine and proline. As for leaves glutamic acid was higher fellowed by aspartic acid, leucine and histidine. Mtehionine and cystine were found in low content in both roots and leaves. Major fatty acid composition in total lipid(free and bound)were linoleic, linolenic and palmitic acid in both and leaves. P, K and Ca were rich minerals contained in the roots and leaves of Wild Youngia sonchifolia Max.

申秀澈 順天大學校 農業科學硏究所 1987 農業科學硏究 Vol.1 No.-

Free amino acids and phenolic compounds in wild Korean lettuce were studied to get the information for final acceptability of products, which had been used as a traditional Kimchi in Korea. In fresh roots and leaves of wild Korean lettuce, Young sonchifolia Max., 17 kinds of free amino acids were determined, respectively. Among them, histidine, serine and arginine were abundant in fresh roots, while histidine, proline and alanine in fresh leaves, especially histidine was the highest contents in both fresh roots and leaves. Cystine, tyrosine, lysine and glutamic acid were found in relatively low content in both fresh roots and leaves. The four fractions obtained from the alcoholic extracts of roots and leaves of wild Korean lettuce were free phenolics, carbonate soluble and alkali-labile bound phenolics, carbonate insoluble and alkali-labile bound phenolics, alcohol insoluble alkali-labile bound phenolics. Phenolics identified from roots and leaves of wild Korean lettuce were phioroglucinol, coumalic acid, catechin, chlorogenic acid, epicatechin and cinnamic acid. Those phenolics existed in the free phenolics from in roots and the alcohol in soluble, alkali-labile bound phenolics from in leaves.

The total number of woody plants species appeared in the investgated area were 31 families 45 genus 79 species including 8 varieties and 1 fomular. Importance values(Ⅳ) of the tree species of forest area in Seoul, Quercus mongolica showed the highest Ⅳ and Robinia pseudoacacia, Prunus sargetii, Pinus densiflora, Quercus acutissima, Sorbus alniflora were dominant species at conopy layer. Importance values of major tree species in relation to topographic feature, Quercus mongolica was higher in northern aspect than in southern aspect and at valley topography was higher than at ridge topography while Robinia pseudoacacia showed higher in southern aspect than in northern aspect and at ridge topography was higher than at valley topography, and Pinus densiflora showed high Ⅳ at ridge topography of southern aspect. As the result of COA Ordination analysis for fifty three plots belong to twenty five survey site of forest area in Seoul were divided into four vegetation communities which were Quercus mongolica-Prunus sargetii community, Quercus mongolica community, Robinia pseudoacacia community, Quercus variabilis community. Shanon’s species diversity indicies range of each community was 1.3822∼1.1189, and Quercus monglica community showed the highest species diversity and Quercus monglica - Prunus sargetii community showd the lowest.

Cheon­Dong valley forest, bearing a cool­temperature, broadleaf­deciduous forest zone, ranging from 500m to 1200m by elevation in Mt. Sobeak National Park area was investigated for forest vegetation structure research. Ten plots of 1000㎡ size set up by the clumped sampling method and Classification and Polar Ordination were applied for vegetation structure analysis by environmental gradient the flora of the vascular plants collected from this investigated area were 32 families, 35 genera, 42 species and 3 varieties. Ranging from 500m to 1200m to elevation, Number of species, Number of individuals and Species diversity showed their highest values at 900m elevation respectively. And with increasing altitude those all values showed a tendency decreasing gradually. According to the Importance Value the leading dominant tree species in canopy layer were Styrax obassia, Quercus variabilis, Q. aliena, Carpinus codata while Lindera obtusiloba, Lespedeza bicolor were in understory at low elevation, ranging from 500m to 900m. Ant at high elevation area, ranging from 900m to 1200m, the leading dominant species were Q. monglica, Q. acutisima, Betula platyphylla var. japonica, Cornus controversa, Acer pseudo­sieboldianum, Fraxinus mandshurica, n canopy layer while Deuzia paviflora, Pinus laxiflora were in understory. The result from Classification and Polar Ordination analysis, they showed similarity that the forest vegetation of Sobeak valley area was classified into two sub­communities, one is Q. mongolica, Styrux obassia―Styrux obassia, Q. aliena, Carpinus codata―Styrux obassia, Lespedeza bicolor community and the other is Q. variabilia, Q. acutisima―Acer mono, Fruxinus rhynchophylla―Deutzia parviflora, Lindera obtusiloba community and the major environmental factors were considered to be the difference of altitude and the conditions of soil pH. The successional trends of tree species will be from Q. variabilis, Q. acutisima through Acer pseudo­sieboldianum, Fraxinus rhynchophylla to Carpinus codata at high elevation area, ranging from 900m to 1200m, and from Q. mongolica, Styrax obassia through Styrax obassia, Q aliena to Carpinus codata at low elevation area, ranging from 500m to 900m.

Free sugars determined from the the roots in Y.sonchifolia were rahmnose, frutose, glucose, sucrose, maltose, melibiose and raffinose. Major sugars, 73.2% of total free sugars, detected from the roots in &. sonchifolia were fructose, glucose and sucrose, whereas raffinose was not detected from the leaves, and major sugars almost like above that of roots, 72.4% in total free sugars. 3. Ascorbic acid contents of the leaves in Y. sonchifolia was 67mg/100g and was higher as compared to that of the roots. 4.

The amino acid, lipid components and chlorophyll content of wild korean lettuce were studied for factors of good production, which has been used as a traditional Kimchi in Korea. Seventeen amino acids except tryptophan were idntified in the root and leaf of wild Korean lettuce. Of amino acid compositions in the root Glu content was highest followed by histidine and aspartic acid. As for leaf Glu content was highest followed by aspartic acid and leucine. Methionine and Cystion were found in relatively low content in both root and leaf. The ratio of neutral lipid. glycolipid and phospholipid in the total lipid were 62.1:22.9:15 in the root, and 62.5:27.7:9.8 in the leaf, respecitvely. Major composition in the neutral lipid were triglycerides, sterylesters, diglycerides and monoglycerides, in both root and leaf. Esterified steryl glycosides, monogalactosyl ciglycerides and stderul glycosides were major compositions of the glycolipids in both roor and leaf. Major faty acid compositions in total lipids (free and bound) were linoleic, linolenic and palmitic acids in both root and leaf. The cholrophyll and total polyphenol contents in the leaf became decreased up to 32.4 and 67.3%, respectively during storage at room temperature.
