Attempts were made to investigate on the fatty acids of Lentinus lepideus Fr. Fats were extracted from its carpophores and saponified with alcoholic potassium hydroxide. Isolated fatty acids were methylated and were subjected to column chromatography and GLC. Six saturated fatty acids, i.e., dodecanoic, tridecanoic, tetradecanoic, pentadecanoic, hexadecanoic and octadecanoic acids were identified. Especially myristic acid was abundant. Four unsaturated fatty acids, i.e., hexadecadienoic, oleic, linoleic, linolenic acids, were identified. Especially oleic and linoleic acid were abundant.

Biodiesel produced from triglyceride which is main component of animal fats and vegetable oils by methanolysis was known for excellent lubricity. In this study, the lubricity of 12 kinds of biodiesel come from vegetable oils were analyzed using HFRR(High frequency reciprocating rig). The biodiesel synthesized from soybean oil has best lubricity by $153{\mu}m$ of wear scar in HFRR and used fried oil's biodiesel has slightly low lubricity by $299{\mu}m$. Also we have found that the lubricity of diesel was improved when mixing ratio of soybean biodiesel was increased in base diesel.

Most of leaf teas, except flower tea, were considered as good materials with basic conditions for tea manufacture because water content was below 6 %, Crude protein was the greatest component in roasted young leaf tea, crude fats in roasted mature leaf tea and ashes in fermented young leaf tea. Caffein were present as the highest amount(5.18%) in steamed mature leaf tea, showing less amount than greenp teas. Catechin were contained as the highest amount in all kinds of teas, especially fermented young leaf tea. was the highest(9.57%). Tannin, which highly related with tea quality including astringent taste, color and perfume, were present as the highest amount in fermented young leaf tea.(중략)

The proximate and amino acid composition of wild and cultivated Cynochum wilfordi, Codopsis lancolata and lxeris sonchifolia were analyzed. Cynochum wilfordi, had higher contents of sugar ascompared with Codonopsis lancolata and lxeris sonchifolia. Fats was 2-3 times higher in Cynochumwilordi then Codonopsis lancolata and lxeris sonchifolia. No significant difference in the contents wasfound between the open field root, spontanity and cultivated at 30'c in biotronroom at condonopsislanceolata. However, contents of protein was 12.8% in lxeris sonchifolia. Total amino acid were 1.5-1.8 times higher in lxeris sonchifolia. than Cynochum wilfordi and Codonopsis lancolata. The decresingorder of the amounts of amino acid infused from the Cynochum wilfordi samples was Glu, Arg, Asp,Leu, Pro, Lys, Codonopsis lancolata (Changdeuk) was Arg, Glu, Pro, Leu, Asp, Lys, Codonopsislanceilata(Chirisan) was Arg, Glu, Pro, Asp, Lys, Leu, Codonopsis lancolata(Yeanbeun) was Arg,Glu, Asp, Leu, Ser, Lys, and lxeris sonchifolia was Glu, Arg, Asp, Cys, Lys, Pro.

The effluent sediment from the land-based seawater fish farms of Jeju consists of proteins, fats, ash and moisture. An evaluation of the effluent sediment as substrate for growth of phototrophic or lactic acid bacteria revealed that the sediment supported the growth of phototrophic bacteria but could support lactic acid bacteria only on supplementation with sugar. The possibility of using phototrophic bacteria for recycling the land-based seawater fish farm effluent is shown.

An attempt was made to produce by using Rh. gracilis (NRRL Y-1091) in the same wav as currently considered siglecell protein production. The lipid content of Rh. gracilis were 56.9％ of dry weight. Economic coefficient (E. C.) and fat coefficient (F. C.) were 31.3 and 17.8, respectivelv. The lipid and fats extracted from Rh. gracilis were characterized as following: Specific gravity 0.875, A.V. 42.5, S.V. 220, I.V. 57.7, Phospholipid 1.58, Unsaponifiables 25.5, Volatile matter 18.7. Fatty acid composition of the lipids were analvzed by HPLC. In addition to the lipid analvsis, proteins were extracted from defatted Rh. gracilis and their amino acid compositions were examined by amino acid analyzer.

The result of the analytical experimental by HPLC on amino acid which is contained in such samples as white-raw-sesame, white-roast -seasame, black -raw -sesame, black-roast-sesame, raw-perilla seed and roast-perilla seed is as follows ; In the six smaples, the amino acid contents in raw seeds were all higher than those in roasted seeds, and the contents of alutamic acid and lysine were more reduced in roasted seeds than in raw seeds. All the amino acid contents except threoninewere highest in raw perilla seed. The amino acids which the six samples contain to a higher degree were in order of glutamic acid (18 %-21%), threonine(16%-19%), glycine (8%-9%), leucine(77.5%), aspartic acid (7%-7.4%), while methinine (1-2%) was contained least in all six samples followed by Isoleucine(3%).

The living body consists of proteins, carbohydrates and fats. The above components are unstable to the change of circumstances ; thus ; when they are buried under the ground for a long time, they are disintegrated by physical effects such as pressure, water etc. However, it was recently reported that the part of the components of living body, especially fat thought in small guantity, remained in a relative stable state for many milleniuns. In addition, turned out that the structure of the composition of the fatty acid and sterol is different according to their species. For example, the plants - rice, barley, bean - and the animals - (togs, cow, pig, fish - have different structure of fat. Residual fat analysis is a research in the chemical composition of fat vemained in archaeological evidences on the basis of chemical structural differences as mentioned here in above. This paper introduces the residual fat analysis of archaeological evidences practical in Japan.

Eco-friendly processing using enzymes has been focused in textile industry in order to reduce environmental pollutions. This paper was suggested to hydrolyze non-cellulose, such as fats and waxes in cotton fabrics by lipase treatment. Enzymatic treatment conditions were controlled according to pH, temperature, enzyme concentration, and treatment time. The physical properties of the lipase-treated cotton fabrics were evaluated by measuring weight loss, moisture regain and dyeing properties. The surface morphology of lipase-treated cotton fabrics were observed by SEM. As a result, the optimum conditions for the lipase treatment were at pH 4.2, temperature 50$^{\circ}C$, concentration 50%, and treatment time 90 minutes. Calcium chloride and Triton X-100 were effective auxiliaries in lipase treatment.

Pancreatic lipase digests dietary fats by hydrolysis, which is a key enzyme for lipid absorption. Therefore, reduction of fat absorption by the inhibition of pancreatic lipase is suggested to be a therapeutic strategy for obesity. We previously reported coumarins and secoiridoids of Fraxinus rhynchophylla as inhibitory constituents on adipocyte differentiation. Further investigation on F. rhynchophylla led to the isolation of lignan derivatives such as lignans (1 - 10), sesquilignans (11 - 14) and coumarinolignans (15 - 17). Among them, coumarinolignans and sesquilignans were first reported from Fraxinus species. Among the constituents isolated, sesquilignans showed the significant inhibition on pancreatic lipase, whereas lignans and coumarinolignans exerted weak effects.
