Soybean is an important economical resource of protein and oil for human and animals. The genetic basis of seed protein and oil content has been separately characterized in soybean. However, the genetic relationship between seed protein and oil content remains to be elucidated. In this study, we used a combined analysis of phenotypic correlation and linkage mapping to dissect the relationship between seed protein and oil content. A $F_{10:11}$ RIL population containing 222 lines, derived from the cross between two Korean soybean cultivars Seadanbaek as female and Neulchan as male parent, were used in this experiment. Soybean seed analyzed were harvested in three different experimental environments. A genetic linkage map was constructed with 180K SoyaSNP Chip and QTLs of both traits were analyzed using the software QTL IciMapping. QTL analyses for seed protein and oil content were conducted by composite interval mapping across a genome wide genetic map. This study detected four major QTL for oil content located in chromosome 10, 13, 15 and 16 that explained 13.2-19.8% of the phenotypic variation. In addition, 3 major QTL for protein content were detected in chromosome 10, 11 and 16 that explained 40.8~53.2% of the phenotypic variation. A major QTLs was found to be associated with both seed protein and oil content. A major QTL were mapped to soybean chromosomes 16, which were designated qHPO16. These loci have not been previously reported. Our results reveal a signi cant genetic relationship between seed protein and oil fi content traits. The markers linked closely to these major QTLs may be used for selection of soybean varieties with improved seed protein and oil content.

This research was designed to study the effect of Korean dietary lipids on the lipid metabolism and the immune function in young rats . The three different lipid sources were compared lard, perilla oil and fish oil. Three different levels of lipid in the diet, 2%, 15% and 30%,on the weight basis, were included. After four weeks feeding, the rats were sacrified and blood sample was collected to analyze for the total lipid, TG and cholesterol contents in serum. The HDL fraction in serum was seperated by the electrophoresis of lipoproteins. The immune responses were measured by the blastogenesis of spleen lymphocyte stimulated by PHA and in serum were measured. The following results were obtained. Lower body weight gain was shown in 30% lipid diet fed group on the isocaloric basis. In concerning the different dietary lipid sources, there were significantly lower boyd weight gain in fish oil than in perilla seed oil and lard group in 30% lipid groups. Deposition of body fat expressed by epididymal fat pad in serum were significantly different among perilla seed oil, lard and fish oil groups. Perilla seed oil group showed lowest level of total lipid and TG in serum regardless of dietary fat level. The feeding perilla seed oil to rats was resulted in lower serum cholesterol levels than lard in all three levels of fats tested. The HDL fraction was elevated in perilla seed oil group at the high fat level. The stimulating responses of lymphycotes by PHA did not seem to be influenced by different dietary fat sources. However, conA mitogenic responses was significantly increased in perilla seed oil group. The lower level of perilla seed oil (2%, 15%) showed slightly higher responses of ConA, indicating that lower level of perilla seed oil might have stimulatory response on the immune response. The number of antibody forming cells of spleen against SRBC was increased in 30% fat level for all the three kind of fats. However, no effect has been found in plaque forming cell response by the differences in dietary fat sources. There were no significant differences in serum IgG and IgA levels in all dietary groups.

This study was carried out using rats weighing $40{\sim}50\;g$ which were devided into seven groups with various diet compositions emphasizing fat levels of perilla seed oil for the period of 41/2 weeks. The levels of fat in the diet were 5%, 10%, 15% and animals were fed ad libitum. The results are as follows : 1) Yellow pjgmentation of both neck and tail was clearly observed in groups fed 10% and 15% level perilla seed oil without vitamin I supplementation (IV and VII). 2) The growth rate in groups fed 15% level perilla seed oil was reduced as compared to that in groups fed 5% or 10% level perilla seed oil. 3) The mean hematocrit values of 15% level perilla seed oil groups tended to be lower than those of control group, tut the differences were not significant. 4) The serum vitamin I concentration showed different value in various groups, the values of control group were significantly higher than those of perilla seed oil groups-15% level with or without vitamin E supplementation (VI and VII) and 10% level without vitamin E supplementation (IV). According to the results, 10% level-perilla seed oil in the diet can be considered safe if vitamin E is not omitted from the vitamin mixture ana the group fed 15% fat with P/S ratio of 1 appeared to be safe during the experimental period. Finally the long-term studios have to be persued in many aspects by using perilla seed oil in the experimental diet. Because rats are known t4 be quite resistant to the experimental diets, comparative studies using various animal species have to he conducted.

압착이나 유기용매 추출방식으로 생산된 포도씨유에는 resveratrol이 함유되어있지 않다 초임계 이산화탄소로 추출하는 경우 포도씨에 존재하는 resveratrol의 약 $1.6\%$가 추출 함유됨을 확인하였다. 초임계 추출 효율은 포도씨 건조 정도에 따라서 달라졌는데, 시료에 수분이 전혀 있지 않은 경우는 resvertrol을 추출되지 않았다. 수분함량이 증가할수록 추출 효율이 증가하는데, 수분이 resvertrol을 추출에 중요한 역할을 하였다. 초임계유체 추출 시간에 따른 추출된 포도씨 유의 resvertol 함량은 초반보다 후반으로 갈수록 증가하는 경향을 나타내었다. 초반에 오일 이 많이 추출되고 이후 수분이 빠져나오는 추출성향을 볼 때, resvertrol추출에는 수분이 초임계유체의 성질에 큰 영향을 미쳐 추출 효율을 변화시키는 것으로 생각된다.

Apart from being used as food, seed oils have also been used traditionally as medicinal products by several communities. However, the full medicinal potential of many seed oil plants is yet to be properly reviewed, particularly for their antimicrobial and antioxidant properties. North-East India has rich resources of seed oil plants. The availability of detailed information on these plants is quite limited. This review aims to explore and evaluate these seed oil plants of the North-East India with particular emphasis on their antimicrobial and antioxidant activities as well as chemical compositions. A comprehensive literature search on seed oil plants of this region has been performed. Seed oil yielding plants of this region can be categorized into two categories: plants that are used traditionally as sources of edible or medicinal oils and plants that are used for purposes other than as sources of oils. Many seed oil plants of this region have been reported to possess antimicrobial and antioxidant properties, and to produce various types of compounds. This review also highlights the importance of these plants in contributing to the local as well as the national economy of India.

Effects of soybean oil or whole cotton seed addition on conjugated linoleic acid (CLA) and performance of fattening Brahman$\times$Thai-Native cattle were studied. Eighteen fattening cattle averaging $241{\pm}24kg$ body weight and approximately 1 year old were stratified by live weight into three groups and randomly assigned by group to one of three dietary treatments. The treatments were control (concentrated 14% crude protein), control and supplemented with 170 g/d soybean oil, control plus 170 g/d of oil from whole cotton seed. All animals were weighed before and after the experimental period and 4 cattle per treatment were randomly slaughtered then carcass measurements were obtained. There were no statistically significantly differences in the final body weight, average daily gain and dry matter intake among treatments. However, the crude protein intake was significantly decreased (p<0.01) when whole cotton seed was fed compared with control and soybean oil treatments. The carcass composition and carcass characteristics were not significantly different in Longissimus and Semimembranosus muscle by feeding soybean oil and whole cotton seed compared with the control treatment. Supplementation of soybean oil increased (p<0.01) cis-9, trans-11 CLA by 116% in Longissimus muscle and by 240% in Semimembranosus muscle. However, whole cotton seed did not increase cis-9, trans-11 CLA in both muscles. The present study successfully increased cis-9, trans-11 CLA content of muscle lipids by soybean oil but not by whole cotton seed.

To secure raw materials of biodiesel production, the possibility of camellia (C. japonica L.) and tea (C. sinensis L.) seed oil was studied to produce biodiesel. In this research, crude oil contents and fatty acid compositions of seeds were analyzed by Solxlet and Gas chromatography (GC). The oil contents in the seeds of camellia were 69.8%~73.8%, and tea were 26.3%~29.4%. Among the fatty acids of camellia and tea oil, oleic acid was dominant. The unsaturated fatty acids accounted for 88.4% and 80.2% of the whole fatty acids of camellia and tea seed oil. Total seed oil content and fatty acid composition of tea seed were influenced by collecting date. Across maturation period, oil content of tea seed averaged 18.3% on $6^{th}$ September increasing to 27.9% by $11^{th}$ October. For largest seed yield and oil content, the optimum time to harvest tea is in middle october, and camellia is late september and thereafter. The extraction efficiency of oil from seeds by extraction methods was determined. Biodiesel were synthesized in 92.1~92.8% yields from camellia and tea oils by transesterification. The biodiesel was characterized by its physical and fuel properties including oxidation stability, iodine value and cold filter plugging point (CFPP). Oxidation stability of camellia was 8.6~8.8 hours and tea was 2.9~3.6 at $110^{\circ}C$. Camellia oil had considerably better oxidation stability and CFPP than tea oil.
