To furnish basic data for the utilizatin of camellia(Camellia japonica L.) seeds as a raw material of industrial products, major chemical components of camellia and defatted camellia seeds were investigated. The moisture, crude ash, crude fat and crude protein contents of camellia seeds were 4.06%, 1.83%, 65.75% and 8.44%, respectively. Defatted camellia seeds indicates that it contains 10.31% moisture, 5.28% crude ash and 17.49% crude protein while no crude fat was detected. The curde ginseng saponin, crude saikosaponin and red ginseng saponin contents of camellia seeds were 108.0mg%, 0.4mg% and 40.3mg%, respectively. Total amino acid contents of camellia seeds and defatted camellia seeds were 7,851mg% and 13,002mg%, respectively, and the major amino acids were glutamic acid, arginine, aspartic acid and leucine. The ratio of essential/total amino acid of camellia seeds was 0.29.

한려해상국립공원 거제도 학동지역 동백나무림 천연기념물의 식물군집구조와 식생관리 방안을 제시하기 위하여 대상지에 46개 조사구를 설정하였고, 식생조사를 실시하였다. DCA분석과 평균상대우점치 분석 결과 46개 조사구는 동백나무군집, 동백나무-사스레피나무군집, 동백나무-참식나무군집. 편백-동백나무군집 등 4개 군집으로 나누어졌다. 군집별 천이경향은 동백나무-참식나무군집은 참식나무로의 생태적 천이가 진행될 것이며, 나머지 3개 군집은 현 상태로 유지될 것으로 판단되었다. 본 대상지의 식생관리는 천이억제형 식생관리가 바람직 할 것으로 보이며, 식생관리에서 제거해야 할 수종으로 단기적으로는 편백. 참식나무, 사스레피나무 3종이며, 까마귀쪽나무, 후박나무, 나도밤나무, 산벚나무, 졸참나무 등 5종은 장기적인 관리대상 수종이었다.

The seeds of wild and cultivated Camellia japonica were studied for their lipid contents and fatty acid composition. The seeds of wild and cultivated Camellia japonica contained 70.2% and 73.4% lipids, respectively. Fifteen fatty acids were identified in the lipids from the Camellia japonica seeds. In addition to confirming the 5 previously reported (16 : 0, 18 : 0, 18 : 1, 18 : 2 and 18 : 3), 10 more acids were characterized. The newly identified acids were 14 : 0, 16 : 1, 17 : 0, 20 : 0, 20 : 1, 20 : 2, 22 : 0, 22 : 1, 24 : 0 and 24 : 1. Both seeds lipids contained 18 : 1 in high levels (81. 6${\sim}$82. 2%). Little difference in fatty acid composition was noted between the wild and cultivated Camellia japonica seed lipids. The fatty acid composition of commercial Camellia japonica oil was similar to those of the Camellia japonica seed lipids.

This study was carried out to examine the effect on the contents of dietary fiber, mechanical properties, and sensory quality of bread contained with 10% of high-fiber Camellia (Camellia japonica L.) seed flour. Bread added by dietary fiber was the contents of moisture, protein and ash higher than control bread, while the contents of lipid lower than that of control bread. The high-fiber with Camellia seed flour contained 8.6% soluble dietary fiber, 43.7% insoluble dietary fiber, and 52.3% total dietary fiber. The ratio of insoluble dietary fiber/soluble dietary fiber in the high-fiber with Camelia seed flour was 5 times. Bread with the addition of dietary fiber contained 6.9% total dietary fiber. With the addition of dietary fiber, water absorption , mixing time loaf weight, and hardness increased, but the loaf volume decreased . The sensory quality on bread added by dietary fiber was somewhat low in color, appearance, crumb texture, mouthfeel, flavor and overall preference was higher than that of control bread.

본 논문은 천연기념물 수림지 조사연구의 결과물로 천연기념물로 지정된 동백나무 숲의 입지환경과 생육환경과 토양환경을 조사하고, 동백나무 숲에 토양이 미치는 영향을 살피기 위하여 상관관계를 분석한 결과는 다음과 같이 요약될 수 있다. 첫째, 천연기념물 동백나무 숲의 입지환경은 산록부의 계곡 또는 하천변에 위치하고 있으며, 일조량이 많은 남동향, 동향, 남향을 주향으로 하고 있어 외부 환경요인에 의한 입지조건은 양호하나, $15{\sim}30^{\circ}$의 경사지에 분포하여 경사에 의한 토양유실의 우려가 나타나고 있다. 둘째, 동백나무 숲의 생육현황은 이령림 경급분포를 나타내고 있으나, 상층의 임목밀도가 높아 하층에 발생된 동백나무 치수의 생장을 저해하고 있다. 또한 수관폭이 좁은 피압목이 발생되어, 평균 수고는 8.09m로, 일반적인 동백나무의 수고에 비하여 낮게 나타났으며, 수관폭 분포는 경급 내 변이가 심하여 상관관계가 낮은 것으로 분석되었다. 셋째, 천연기념물 동백나무 숲의 토양성분은 토성, 토양산도 등 10개 항목을 분석하였다. 이의 결과를 종합하면 토성, 토양산도, 칼슘, 유기물, 마그네슘 함량은 양호하였고, 칼륨은 부족하였으며, 질소와 인산은 과잉으로 확인되었다. 넷째, 동백나무 숲의 생육상태와 토양 이화학적 특성간의 상관관계 분석을 실시한 결과, 마그네슘과 칼슘 및 질소전량에 한하여 토양의 이화학적 특성이 동백나무 숲의 생육에 영향을 미치는 요인으로 나타났으며, 마그네슘, 칼슘, 질소전량의 항목을 제외한 7가지 항목은 동백나무 숲의 생육에 영향관계가 없는 것으로 나타났다. 향후 동백나무 숲의 생육현황과 토양과의 관계 및 토양환경뿐만 아니라, 동백나무 숲의 생육상태에 영향을 미치는 요인을 장기적으로 모니터링하여 생태적으로 안정된 동백나무 숲의 보전과 현황자료 구축을 위한 연구가 계속되어야 할 것이다.

To developed natural food preservatives, ethanol and water extracts were prepared from the defatted camellia(Camellia japonica L.) seeds. Antimicrobial activities were examined against 14 microorganisms which were food borne pathogens and/or food poisoning microorganisms and food-related bacteria and yeasts. Ethanol extract showed antimicrobial activities against several microorganisms tested, but not on lactic acid bactria. Especially, minimum inhibitory concentrations(MIC) for yeasts were as low as 1mg/ml. Water extract exhibited antimicrobial activities for the yeasts tested, but almost bacteria were not observed. The ethanol extract was fractionated in the order of hexane, chloroform, ethylaetate and butanol fractions to test antimicrobial activity. The strongest activity for the tested yeasts were found in the butanol fractions, but bacteria were chloroform fraction. Hansenula anomala treated with ethanol were observed by scanning electron micrograph, and the results exhibited morphological changes, including the irregularly contracted cell surface and expanded ellipsoidal shape.

This project was conducted to development several camellia tea mixed herb teas having any physiological effects. Leaves of tea tree contain many compounds, such as polysaccharides, volatile oils, vitamins, minerals, purines, alkaloids(eg. caffeine) and polyphenols(catechins and flavonoids). Although all three tea types(green, oolonr and black) have antibacterial and free radical capturing(antioxidizing) activities, the efficacy decreases substantially the darker the variety of tea is. This is due to lower contents of anti-oxidizing polyphenols remaining in the leaves. Unlike tea tree(Camellia sinensis), the biochemical features and effects of camellia(Camellia japonica) are not well known. Fresh mature leaf of sasanqua camellia(C. sasanqua), roasted young leaf tea(C. japonica) and fresh mature leaf and bark of camellia had high antibacterial activity against P. vulgaris and B. subtilis. In antifungal activity bioassay, young leaf roasted teas of camellia and sasanqua camellia had high activity against C. albicans and T. beigelil. Plant extracts from Camelia japonica had higher inhibitory activity against fungi than against bacteria. In cytotoxic effect against human acute myelogenous leukaemia cell extracts including fresh leaf(200$\mu\textrm{g}$/m1), bark(230$\mu\textrm{g}$/ml) and flower tea (320$\mu\textrm{g}$/m1)inhibited growth of AML cells.(중략)

Phytosociological investigation of the forest vegeation was carried out in Kumo archipelago at the period of May 21th 1990 to May 29th 1990 by Braun-Blanquet's method. The forest vegetation was classified into 7 communities, Camellia japonica, Castanopsis cuspidata var. sieboldii, Machilus thunbergii, Camellia japonica-Pinus thunbergii, Camellia japonica-Torreya nucifera, Carpinus coreana and Quercus acutissima community. Based on the classification of communities, the actual vegetation maps were drawn in 1 : 50,000 scale.

Objectives : This study was carried out to investigate the biological activities of methanol extracts of fermented Camellia japonica leaf and flower. Methods : Methanol extracts of fermented Camellia japonica leaf and flower were prepared and a dose of 100 and 400mg/kg/day was administered orally into mice. And after appropriate weeks, changes of serum enzyme activities were investigated to confirm its effects on serum glucose, cholesterol and short term administration safety. Results : Fermented flower extract showed significant decrease of serum level of cholesterol. And showed no toxicity on kidney and liver within the dose of 400mg/kg/day. Conclusion : Thus above result showed no toxicity on kidney and liver in male and female mice.
