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.

신수철(Soo-Cheol Shin),강성구(Seong-Koo Kang),장미정(Mi-Jeong Jang) 한국자원식물학회 2003 한국자원식물학회지 Vol.16 No.3

흑오미자를 이용하여 음료를 제조하는데 필요한 여러 가지 가공적성 가운데 가공제품의 생산과 상품성에 관련이 깊은 몇 가지 특성을 한국산, 중국산 오미자와 비교 조사하였다. 흑오미자로부터 온도(80, 40℃), 추출시간 (3, 4, 5, 7시간), 추출용매(증류수, 20% 에탄올)를 사용하여 즙액의 추출 수율과 색도, 당도(가용성 고형분) pH을 측정하여 한국산 오미자와 중국산 오미자를 비교한 결과, 수율을 기준으로 한 흑오미자의 추출조건은 20% 에탄올 수용액으로 80℃ 물 중탕에서 3시간 추출이 가장 적합하였다. 추출액의 색도 측정에서 L값(투명 도)은 80℃로 4시간, 20%에탄올 추출액이 낮고 40℃로 물 추출액이 높았다. a값(적색도)은 80℃, 4시간 20% 에탄올 추출물이 가장 높았으며, b값(황색도)은 온도가 높고 (80℃, 5시간)장시간 증류수 추출액이 높아 적색색소의 추출방법과 차이를 나타내었다. 흑오미자 추출물의 당도는 2.0에서 2.6%Brix 범위로 오미자 추출물보다는 낮았으며, pH는 3.39­3.62 범위로 산성을 나타내었고 오미자 즙액 의 안정한 적색을 나타내는데 충분한 pH 범위이었으며, 흑오미자 줄기의 즙액도 증량제로 이용할 수 있는 가치가 있는 것으로 사료되었다. To determine the properties for juice preperation of Black Omija (Schizandra nigra Max.) and Omija (Schizandra chinensis), yield of extraction, chromaticity and lightness, pH and soluble solid of the extract were investigated. The rate of extract yield from Schizandra nigra was highest when extracted for 3 hours at 80℃ in 20% ethanol solution. For the desirable chromaticity coordinates, the optimum extraction time and temperature of Schizandra nigra extract were 3 hours at 80℃. The lightness of the extract was low of the value when extraction time and temperature was long and high. The sugar content of the extract of S. nigra was 2.0­2.6% Brix, lower than that of S. chinensis, but the difference was insignificant. The pH of the extract from S. nigra was 0.1­0.2 higher than that of S. chinensis. Although the pH of the extract from S. nigra was a little low when extracted by water, the pH range was enough to maintain the stability of color of extract from the S. chinensis.

매실을 이용한 가공제품의 품질을 결정하는 여러 가지 물리 화학적 성질을 조사하기 위하여 1993년 6월 18일과 6월 28일 2회에 걸쳐 수확한 6가지 매실 품종의 가공적성에 영향을 주는 주요 성분을 측정한 결과는 다음과 같다. 1. 매실의 증량은 완숙기까지 증가되어 6월 28일까지 증가되었고 과실에서 씨의 중량을 뺀 과육자체의 중량인 과육율도 증가되었다. 그러나 소매는 6월 28일에 낙과가 많아지면서 중량과 과육율이 감소되어 6월 28일 이전에 수확해야 될 품종으로 생각되었다. 2. 매실의 경도는 2.5-3.9Kg/$mm\varphi$로 나타났는데 완숙기까지 성숙될수록 감소하는 경향을 보였고, 3. 수분은 88.5%-99%로 일본산 매실보다 수분함량이 높은 것으로 나타났으며 조회분은 0.6%-0.7%이었다. 4. 매실의 산도는 구연산함량으로 6.2%-7.5%이었는데 수확기가 완숙기로 갈수록 증가하는 경향을 나타냈으며 이러한 내용을 조사하기 위하여 비휘발성 유기산 함량을 분석하였다. 매실과육중의 주요 유기산은 구연산과 사과산으로 검출되었고 구연산은 완숙기로 성숙하면서 증가하였으나 사과산은 감소하는 경향이었는데 전체량은 성숙될수록 증가하였으며 앵숙, 남고, 소매에 많은 량이 함유되었다. 5. 매실 과육의 유리당 함량은 2.5%-3%였는데 과당과 포도당이 주요한 유리당으로 나타났고 수확시기에 따른 변화는 거의 없는 것으로 나타났다. 6. 비타민 C는 0.6-2mg%함유되었는데 앵숙을 제외한 다른 품종들은 완숙기로 성숙되면서 감소되었다. 7. 그리고 매실을 알카리성식품으로 판정하는데 중요한 요소인 금속 무기성분은 칼륨, 칼슘, 마그네슘, 나트륨 순으로 많았는데 나트륨과 마그네슘은 소량이 함유되었다. To elucidate the effect on the quality of products, various components of ume fruit(Prunus mume)flesh of six species during development and maturation. The weigh and the rate of flesh of ume fruit was increased until maturation, except of small ume. The relative hardness of ume fruit flesh was 2.5~3.9 Kg and decreased at full ripe. The major organic acids of ume fruit flesh was citric acid and malic acid. Citric acid became increased, but malic acid was decreased during maturation and total content of that was increased during maturation Free sugars determined from the ume fruit flesh were fructose, glucose, sucrose. Ascorbic acid content was $0.6\sim2mg%$ in the ume fruit flesh. The contents of K and Ca were abundant minerals in ume fruit flesh.

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.
