Xanthoceras sorbifolium is considered as bio-energy crops owing to the high oil content from kernel. This study was performed to analyze calorific value, crude ash content, ultimate ratio, crude lipid and fatty acid composition among seed sources. Calorific values ranged from $4,526.0\;cal\;g^{-1}$ to $7,377.2\;cal\;g^{-1}$ in seeds and kernels showed the highest value. Calorific values and crude ash contents were observed as significant difference among plantations and/or individuals (p>0.05). Kernel from SD-F plantation showed the highest calorific value and lower crude ash content. C content comprised 63.4%, the highest levels was detected from SD-F (64.8%). Crude lipid content in kernel observed as 54.5 g $100\;g^{-1}$ from SD-F. In contrast it was determined the lowest value from LN-JARS as 46.5 g $100\;g^{-1}$. The fatty acid composition of kernel was determined to those of oleic acid (31.3%) and linoleic acid (38.1%) from SD-F and LN-JARS. These results will be offered to useful information for breeding materials selection.
Seasonal variation of uraenesox cinereus) muscle was investigated. Crude lipid content varied from 3.85 to 12.59 g/100g, comprising the highest content in November. The major fatty acids of total lipid, neutral lipid, and phospholipid were C16:0, C23:0, C16:1, C18:1, C20:5, and C22:6, but in phospholipid, Cl8:3n-6 was also the major fatty acid. The C22:6 content of the neutral lipid was much lower compared to that of the total lipid and phospholipid. The content of polyunsaturated fatty acids (ranged from 73.93 to 66.23%) in phospholipid was higher than that of any other lipid fraction. In glycolipid, C20:1 and C14:1 were higher compared to those of any other lipid fraction, but C20:5 and C22:6 were lower. The annual average ratio of n-3 to n-6 of total lipid, neutral lipid, phospholipid, and glycolipid was 10.82, 12.27, 6.63, and 6.50, respectively. The particular trend of seasonal variation of fatty acid composition was not showed in total and neutral lipid. However, the samples caught in September and November had a high crude lipid content with a significantly lower content of polyunsaturated fatty acids in phospholipid. Also, the content of monounsaturated fatty acids in glycolipid was lower in samples of September, November, and January.
The present study has been undertaken to investigate the effects of crude ginseng extract added to food on the lipid composition in serum of rats fed lard and alcohol. Thirty-five males of Sprague-Dawley strains weighed about 130 g were divided into 7 group, each group receiving a different diet for 10 weeks ; i.e. basal diet plus 15% lard, basal diet plus 5% alcohol, basal diet plus 0.5% crude ginseng extract, basal diet plus 15% lard and 0.5% crude ginseng extract. Determinations were carried out on the net weight gain, food efficiency ratio, weight of organs, triglyceride, total cholesterol, HDL-cholesterol, free cholesterol. The results obtained were as follows : 1. Rats given feed containing lard and alcohol showed significant decrease in net weight gain, but crude ginseng extract caused an increase in food efficiency ratio. 2. Lard supplementation group showed increase in the weight of liver, kidney, spleen, but another groups did not. 3. The contents ratio of triglyceride, total cholesterol in serum of lard-fed group showed significant increase compared to controls and but the simultaneous supplementation of crude ginseng extract and lard decreased significantly than those of lard-fed group. 4. The contents of free-cholesterol and ester cholesterol in serum of the simultaneous supplementation of crude ginseng extract group decreased as compared with the lard single fed group. 5. Crude ginseng extract single-fed groups. 6. The ratio of contents of VLDL, LDL-cholesterol in serum was significantly high in the only lard containing group and alcohol group, the crude ginseng extract supplemented group was showed lower tendency than only lard and alcohol group. The above results suggest that crude ginseng extract would prevent the metabolic disease by improving hyperlipoidemia.
The possibility of grape seeds as industrial resources was tested by analyzing various chemical proper-ties of their oils from seven different species. The range of crude oil content of the grape seeds was 26.0-32.0% showing the highest content in Steuden, Mean individual fatty acid contents in the grape seeds were lioleic (70.75%) oleic (18.48%) stearic (2.01%) and palmitic (8.45%) acids. Stearic acid was low in Jingyu and high oleic acid was found in Fugiminori compared with other grape strains. Total lipirds were consisted of nutral lipid (87.25%) glycolipid(4.68%) and phospholipid *8.06%) Content of crude proteins was approximatery 11.2% with some variation between strains. Total sugar content was 2.35~5.63$\mu$g/mg with reducing sugar 3.20$\mu$g/mg. Mean saponification value of crude oils was 186.3mg.KOH.oil Antioxidant activity of grape seed oils was better than that of sesame oil resulting in the hi-oils and sesame oil after heat treatment at 18$0^{\circ}C$.
This study was conducted to investigate the nutritional constituents of pine pollen and the effects of pine pollen on rat liver. Using the chemical components analysis method, the constituents of pine pollen are crude protein(13.97%). crude lipid (6.50%), crude ash (3.25%). Detectable in pine pollen are main fatty acids and non-essential amino acids such as glutamic acid and aspartic acid such as oleic and linoleic acid and 18kinds of amino acid including essential amino acids. The effects of pine pollen on rat liver fed with a high fat diet for 6 weeks showed significant decrease in total lipid and triglyceride as compared with the group fed with a fat diet only. Total cholesterol content decreased by 20.33%. No significant difference was found in total protein content of each group. Pine pollen Is efficacious in preventing geriatric diseases (arteriosclerosis, hyper-lipidemia and cardiovascular system-related diseases).
The contents of crude fat were remarkably different according to parts in porcine tissues. The most contents of total lipids in variety tissues were neutral lipid, and the nexts were phospholipid and glycolipid, where these of the most composition in liver were phospholipid and the next neutrallipid and glycolipid. The major component of the nonpolar lipids in fresh was triglyceried(58.09∼74.68%) and phospolipid in the polar lipid were phosphatidyl choline(20.14∼45.17%) and phosphatidyl ethanolamine(18.5∼30.14%) and the main component in glycolipid acylsterol glyceride(26.10∼45.15%), respectively.

This study was performed in order to determine the processing conditions (pre-drying at room temperature for 0 or 30 min, frying at $160^{\circ}C$ for 1 min or at $180^{\circ}C$ for 40 sec, and soaking for 0~24 h) of Sasambeong recorded in the "Sumunsasul". The Sasambeong was evaluated for crude lipid content, hardness, Hunter's color values, and sensory characteristics. After pre-drying at room temperature for 30 min, the crude lipid contents and hardness of Sasambeong were significantly increased. In addition, the crude lipid content and hardness of Sasambeong did not differ significantly according to the frying conditions. After pre-drying, the sensory characteristics of Sasambeong showed more improvement. The crude lipid content, hardness, Hunter's color values, and sensory characteristics of Sasambeong, which were prepared according to different soaking times (0, 6, 12, or 24 hr) were investigated. As soaking time increased, the crude lipid content and hardness of Sasambeong decreased with a range of 25.43~24.31% and 525.90~388.98 g, respectively. The sensory characteristics of Sasambeong showed no significant difference according to the soaking time. Overall, we think that the best processing conditions of Sasambeong were pre-drying at room temperature for 30 min and then frying at $160^{\circ}C$ for 1 min.

In order to evaluate adaptation to the environment in released fish, digestive organ and body composition were compared among 1-year old cultured (CUL), released (REL) and wild (WIL) Black Sea Bream, Acanthopagrus schlegeli. Hepatosomatic index (HSI) of the REL was significantly lower than those of the CUL and WIL fish, but intestine weight index (IWI) of REL was significantly higher than those of the CUL and WIL fish. There were no significant differences in stomach weight index (SWI) and condition facto. (CF) among those different fish groups. The number of pyloric caeca of the REL and WIL fish were 4, but the $30{\%}$ of CUL fish was 3 counts. The moisture content of whole body in the WIL fish was significantly higher than the CUL and REL fish, but significant lowest in the crude lipid of whole body. The content of moisture and crude protein of dorsal muscle were no significant differences among the CUL, REL and WIL fish, but crude lipid content of WIL fish was significantly lower than the CUL and REL fish. Moisture content of CUL fish in the liver was significantly lower than the REL and WIL fish, and crude lipid was significant lowest in the WIL fish. Amino acid content of dorsal muscle in the WIL fish was highest in the total amino acid, EAA and E/A ratio, and CUL fish was highest EAA and E/A ratio in liver. EPA content in dorsal muscle of WIL fish was lower than CUL and REL fish, and the REL fish was highest in DHA content of the fatty acid. EPA content in liver of WIL fish was lower than CUL and REL fish, and DHA content in REL and WIL fish was highest and lowest. Crude protein content of CUL and WIL fish in the scale was significantly higher than REL fish, but there were no significant differences in contents of crude lipid and ash. Ca and P of scale were formed most of mineral and content of P in CUL fish was significantly higher than those of REL and WIL fish. There were no significant differences in Mg, K, Na and S of scale, but CUL fish was significantly lower than REL fish in C1. The results suggest that difference of digestive organs and body composition concluded it from differences of inhabitation environment and feed formulations.
This study was aimed at investigating the differences in chemical composition of antler according to growing days (80 d and 90 d after casting) and sections (upper, middle, base) in elk. Antlers of six bulls (aged 3 years) cutted on day 80 and 90 after casting were used in this trial and compared chemical composition such as crude protein, crude fat, crude ash, calcium, magnesium, amino acids, lipids, and fatty acids. The contents of crude protein and ether extract were higher in antlers cutted on day 80 than in antlers cutted on day 90, but that of crude ash was higher in antlers cutted on day 90. Significantly difference was observed in crude protein content between growing days in middle part of antler (p<0.05). Calcium and magnesium contents were higher on 90 d than 80 d, but there was no significant difference between growing days of antler. Based on the growing period of antler, there were significant differences (p<0.05) in aspartic acid, threonine, valine, leucine, phenylalanine and lysine, and essential amino acids content was higher in antlers cutted on day 80. Total lipid, neutral lipid, and phospholipid contents were higher in antlers cutted on day 80 than in those cutted on day 90, sphingo-phospholipid content was higher than glycerophospholipid content and values was higher in antlers cutted on day 80 than in those cutted on day 90. For total fatty acids, unsaturated fatty acids composition, there was no significant difference between growing periods of antlers, but values was higher on day 80 than on day 90. Essential fatty acids contents were lower in antler cutted on day 90 than antlers cutted on day 80 and higher for upper part than lower part.

A $3{\times}3$ factorial study was conducted to investigate the effects of dietary protein and lipid levels on the growth, feed utilization and innate immunity of red seabream Pagrus major. Nine diets consisting of three protein levels (42%, 46% and 50% crude protein) and three lipid levels (10%, 14% and 18% crude lipid) were formulated. Triplicate groups of red seabream were fed the experimental diets to apparent satiation (5-6 times a day, from 08:00 to 18:00 h at 2-h intervals) for 10 weeks. At the end of the feeding trial, the weight gain and specific growth rate of fish fed P46L14 (46% protein and 14% lipid), P50L10 (50% protein and 10% lipid) and P50L14 (50% protein and 14% lipid) were significantly (P<0.05) higher than those of fish fed P42L18 (42% protein and 18% lipid). The feed conversion ratios (FCR) of the fish were affected by dietary lipid levels (P<0.039), but not dietary protein levels. The FCR tended to increase with increasing dietary lipid levels from 10% to 18% with the 46% and 50% protein levels. The weight gain, protein efficiency ratio, specific growth rate, feed intake and survival of fish were not affected by either dietary protein or lipid levels. Myeloperoxidase activity in the group fed P50L14 (50% protein and 14% lipid) was significantly higher than that in the group fed P42L10 (42% protein and 10% lipid) or P50L18 (50% protein and 18% lipid). However, the myeloperoxidase activity of fish was not affected by either dietary protein or lipid level. The fish fed P46L14 (46% protein and 14% lipid) and P46L18 (46% protein and 18% lipid) showed significantly higher superoxide dismutase activity than did the fish fed P46L10 (46% protein and 10% lipid), P50L10 (50% protein and 10% lipid) of P50L18 (50% protein and 18% lipid). In conclusion, the optimum protein and lipid levels for the growth and feed utilization of juvenile red seabream were 46% and 14%, respectively, and the optimum dietary protein to energy ratio was 27.4 g/MJ.
