  • Several unusual fatty acids including myristic acid (14 : 0) and lauric acid (12 : 0) were investigated in the Iris family and other related plants. Especially the roots of Iris tecorum contained 75.9% myristic acid in total fatty acid contents and that of Iris germanica contained 57% myristic and 15.5% lauric acid (12 : 0) whereas 10.7% lauric acid and 9.5% capric acid (10 : 0) were detected in the roots of iris ensata as compared to the total fatty acid contents. The total fatty acid contents in the seeds of Foeniculi fructus and Torilis japonica was relatively higher 193.3 mg/g dry wt and 128.2 mg/g dry wt, respectively. 64.5% linoleic acid (18 : 2) and 48.9% ${\alpha}-linolenic$ acid (18 : 3) were observed in the seeds and leaves of iris tectorum whereas its lateral roots contained 9.5% caprylic acid (8 : 0) and 8.6% capric acid. The percentage of myristic acid of the total fatty acid in the immature seeds of iris tectorum and Iris germanica was 10.8% and 15.6%, respectively.

  • This study was conducted to develop environment-friendly agricultural products with anti-microbial activity against Acidovorax avenae subsp. citrulli as a pathogen of bacterial fruit blotch in cucurbit. Schlechtendalia chinensis was extracted by MeOH and solvent fraction. The hexane fraction, which showed highest value of anti-microbial activity, was analyzed by GC-MS. Each mass spectra, corresponding to each peak of chromatogram, was compared to MS database of Wiley library. As a result, myristic acid, palmitic acid and 3-n-pentadecylphenol were identified as maine compounds showing antimicrobial activity against A. avenae subsp. citrulli. Bioassay using commercial myristic acid, palmitic acid and 3-n-pentadecylphenol to test for the anti-microbial activity conformed the anti-microbial activity of potential active compounds, and myristic acid and 3-n-pentadecylphenol showed strong activity. In conclusion, myristic acid and 3-n-pentadecylphenol identified from S. chinensis were anti-microbial chemicals.

  • The interaction and detergency between oily soil and surfactant solution were studied Samples used were tristearin, tripalmitin and their mixture as a triglyceride, myristic acid as a fatty acid and sodium dodecyl sulfate (SDS) as surfactant. The results were as follows: 1. The mixtures of model oily soils were formed of eutectic point and their melting point were lower than them of individual oily soils. 2. The formation of liquid crystalline (LC) phase was recognized in the triangle phase diagram for SDS~ water~model oily soil system. The areas of LC phase region were in the order of SHS~ water~myristir acid> SDS~ water~mixture of tristearin, tripalmitin and myristic acid (TS/TP/M)>SDS~water~mixture of tristearin and tripalmitin (TS/TP) 3. The LC phase region expanded to wide concentration range of SDS solution and high concentration range of model oily soil with increasing temperature. Particularity, the LC phase region expanded highly at $30~40^{\circ}C$ but when the temperature was elevated above $40^{\circ}C$, expanding tendency decreased. 4. In the system of myristic acid and TS/TP/M contacted with SDS solution, the LC phase was already formed at $28^{\circ}C$ and the region of the LC phase were expanded with increasing temperature. But in the system of TS/TP contacted with SDS solution, the LC phase was not formed in whole experiment temperature. 5. The detergency of myristic acid was very high ann it was recognized that the formation of the LC phase played an important role in the detergency. The detergency of TS/TP was very for low, but when TS/TF was mixed with myristic acid, the detergency of TS/TP increased. It is supposed that the LC phase was formed butween SDS solution and myristic acid promoted to penetration of SDS solution into the inner parts of TS/TP.

  • This investigation on the composition of fatty acids of hempseed through gas -chromatography analysis found the follwing results. Myristic acid and other ten materials were detected. And there was mainly composed of myristic acid 29.4%, Palmitoleic acid 16.2%, linoleic acid 14.9%, oleic acid 12.4%. It also showed that heptadecanoic acid 10.8%, erucic acid 0.5%, docosahexaenoic acid 0.3% and essential fatty acid were contained 11.9% between them. As stearic acid, docosahexaenoic acid, linoleic acid and arachidonic acid made lower cholesterol level in body, they will help prevention of senile disease with the oil d hemp seed.

  • For the purposes of clarifying the changes of fatty acid content in seeds of korean mung bean during the ripening process, samples ranging in five stages-10.15,20,25 and 30 days after blooming were collected and analyzed by gas liquid chromatography (GLC). The results obtained were as follows; The content of crude fat increased as ripening. Fatty acids detected in all stages were myristic acid palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid. Myristic acid and palmitic acid were not almost detected above the 3rd stage. Linoleic acid was the largest and the content of oleic acid and linolenic acids was similar. The saturated and unsaturated fatty acid ratio during the ripening process was 16-19/81-84%.

  • To investigate the compositions of Holstein colostrums, samples were collected at 12 hour-interval after 12hrs postpartum. Milk protein, milk fat, SNF and total solid content of the colostum rapidly decreased from 12 hours to 48 hours after calving whereas lactose was the lowest at 12 hours after calving. Ash content was not shown to changes during lactation periods. Immunoglobulin G(IgG) concentration was also significantly(p<0.05) high in both primiparous and multiparous colostrum collected at 12 and 24 hours after calving. IgG concentration of primiparous and multiparous colostrums at 12 hours after calving was 44mg/ml and 44.27mg/ml, respectively. There was no apparent difference in IgG level between primipara and multipara. Fatty acid composition of colostral lipid was not shown to changes during lactation period. However, lauric acid, myristic acid and total saturated, fatty acid were slightly decreased in multiparous colostral lipid. Capric acid, myristic acid and palmitoleic acid composition in primiparous colostral lipid were slightly higher than those of multiparous colostral lipid throughout all lactation periods.

  • The fatty acid compositions of oocytes, follicular, oviductal and uterine fluids of pig and cow were analyzed using gas chromatography. Myristic (C 14: 0), palmitic (C 16: 0), palmitoleic (C 16: 1), stearic (C 18 : 0), oleic (C 18: 1), linoleic (C 18: 2), linolenic (C 18: 3) and arachidonic (C 20: 4) acids were identified as the common fatty acid constituents with little exception. Oleic acid composition was the highest (21.90 to 36.24%) in both pig and cow followed by palmitic (18.61 to 31.90%) and stearic (10.34 to 20.39%) acid. The three polyunsaturated fatty acids like linoleic, linolenic and arachidonic acids were detected in both pig and cow reproductive fluid samples. Myristic acid was not detected in pig oviductal fluid. Similarly, in cow oocytes myristic, palmitoleic and linolenic acids were not detected. Moreover, palmitic, stearic, oleic and linoleic acid comprised about 80% (73.74 to 88.00%) of the total fatty acids in the different samples analyzed in both animals.

  • In order to investigate the information for effective detection and developing of latent fingerprints, we identified fatty acids composition of latent fingerprints on non-porous evidence surface and the chemical changes of latent fingerprint residue after print deposition during 7 months. Fingerprints from eight Korean male donors (aged 29-50 years) and one female donor (aged 36 years) were collected. All fingerprints were found to contain lauric acid (C12:0), myristic acid (C14:0), palmitic acid (C16:0), stearic acid (C18:0), elaidic acid (C18:1n9t), oleic acid (C18:1n9c), linoleic acid (C18:2n6c), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9) and docosadienoic acid (C22:2) and primarily palmitic acid (35.45-48.37%), oleic acid (14.84-28.49%), stearic acid (9.71-24.96%) and linoleic acid (7.68-18.8%) occupied 75% of total fatty acids. When the fingerprints were deposited at dark room for 7 months, total fatty acids components decreased about 12-25%. It can be explained that significant degradation of long-chain fatty acids such as elaidic acid (C18:1n9t), arachidic acid (C20:0), linolenic acid (C18:3n3), erucic acid (C22:1n9), and docosadienoic acid (C22:2) resulted in the generation of myristic acid (C14:0), myristoleic acid (C14:1) and pentadecanoic acid (C15:0).
