  • An attempt was made to investigate free and bound lipid contents and fatty acid compositions of ginseng and its eveven kinds related crude drugs. Contents of free and bound lipids of ginseng were 1.23% and 0.47%, and those of the related crude drugs were $0.31{\sim}13.05%$ and $0.26respectively. Fourteen even-numbered and 4 odd-numbered fatty acids were identified by GLC in those lipids from ginseng, and the major fatty acids were linoleic, palmitic, oleic and linolenic acids. The crude drugs are notably different from ginseng in kinds and compositions of fatty acids of free and bound lipids. Composition ratios of unsaturated fatty acids were higher in free lipids from ginseng than those of the crude drugs except 'Won-ji' Polygalae Radix.

  • Korean ginseng (Panax ginseng C. A. Meyer) has been used as an important medicinal plant in the Orient for a long time. It has been claimed that ginseng has many beneficial bioactive effects on human health, such as antitumor, antistress, antiaging and enhancing immune functions. Red ginseng possibly have new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steaming and drying process was used for the processes of green tea, Polygonatum odoratum, and Rehmanniae radix preparata. In this study, ingredient conversion of ginseng by 9 repetitive steaming and drying process were investigated measuring conversion efficiency of brown materials, crude lipids, crude proteins and aromatic compounds. Brown materials, as an antioxidant, in red ginseng were produced through non-enzymatic reaction by heat. Repetitive steaming and drying treatments on ginseng root contiunously increased the content of brown materials and the chromaticity. Crude lipids were degraded by heat and converted into volatile aromatic ingredients. Crude lipids were degraded and decreased by 0.52% after the 5th and 7th. Crude proteins were also decomposed and converted to amino acid. Crude proteins after the 9th treatment were decreased by more than 85% as increased times of treatments. A bicyclogermacrene as aromatic material was decreased as increased treatment times, while but a aromatic caramel was increased.

  • The effect of temperature and ethanol concentration on lipids yield and free fatty acids were investigated during 1-5 times of 8 hours extraction. The crude lipids recovered was generally increased as the ethanol concentration increased while it was decreased at higher extraction temperature. Fatty acids composition in free fatty acids showed linoleum and plasmatic acids to be the major fatty acids, accounting 60% of 16 fatty acids identified. Fatty acids pattern was little affected by the changes in ethanol concentration while increase in temperature resulted significant changes in fatty acids composition.

  • Nutritive value of lipids was associated with composition of fatty acid. Unvalance diet may increase the incidence of diseases. Abundant of EPA and DHA, polyunsaturated fatty acid, were contained in fishes. Studies on 10 kinds of fishes, lipid components were determined. The results were as follows; 1. The content of crude fat 18.1% were high in eels, on the contrary the content of EPA 0.1% and DHA 0.1% were low. The content of crude fat were low in mackeral and sadrine, but the content of poly unsaturated fatty acid were high. 2. Iodine value 189 was high in sadrine, consequently, this results showed the interrelation between Iodine value and the content of polyunsaturated number. 3. The content of crude fat 1.3% in flounder(sole) were low and the content of cholesterol 20 mg% were lowest in present studies.

  • In this study, crude glycerol was used as a carbon source in the cultivation of wild yeasts, aiming at the production of microbial lipids and citric acid. Forty yeasts of different sources were tested concerning their growth in crude and commercial glycerol. Four yeasts (Lindnera saturnus UFLA CES-Y677, Yarrowia lipolytica UFLA CM-Y9.4, Rhodotorula glutinis NCYC 2439, and Cryptococcus curvatus NCYC 476) were then selected owing to their ability to grow in pure ($OD_{600}$ 2.133, 1.633, 2.055, and 2.049, respectively) and crude ($OD_{600}$ 2.354, 1.753, 2.316, and 2.281, respectively) glycerol (10%, 20%, and 30%). Y. lipolytica UFLA CM-Y9.4 was selected for its ability to maintain cell viability in concentrations of 30% of crude glycerol, and high glycerol intake (18.907 g/l). This yeast was submitted to lipid production in 30 g/l of crude glycerol, and therefore obtained 63.4% of microbial lipids. In the fatty acid profile, there was a predominance of stearic (C18:0) and palmitic (C16:0) acids in the concentrations of 87.64% and 74.67%, respectively. We also performed optimization of the parameters for the production of citric acid, which yielded a production of 0.19 g/l of citric acid in optimum conditions (38.4 g/l of crude glycerol, agitation of 184 rpm, and temperature of $30^{\circ}C$). Yarrowia lipolytica UFLA CM-Y9.4 presented good lipid production when in the concentration of 30 g/l of glycerol. These data may be used for production in large quantities for the application of industrial biodiesel.

  • This study was undertaken to analyze proximate comosition, mineral contents and fatty acid composition of pure jemsosojoo(PJ) and jemsosojoo added medicinal herb(JMH). Mositure, ash, crude protein and crude fat of pure jemsosojoo were higher than those of the JMH, but carbohydrate content was higher in the JMH. Among minerals, Ca, Mg, Fe, Zn content of the JMH were higher than those of the PJ, while P and Na were higher in the PJ and those difference were significant between the PJ and the JMH(p<0.05). U/S (unsaturaed fatty acid/saturated fatty acid) ratio was higher in the JMH than those of the PJ, the ratio o fglycolipid was 1.75 in the PJ and that of neutral lipid was 3.07 in the JMH. Octadecenoic acid, hexadecanoic acid, octadecenoic acid and hexadecenoic acid were major fatty acids in the total lipids, neutral lipids glycolipids and phospolipids of the PJ and the JMH. Especially, octadecadienoic acid and octadecatrienoic acid were higher in the JMH than those of the PJ.

  • 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.
