To investigate fatty acid constituents and relative compositions in the fluid of the follicles, oviducts, uterine ho군 and uterine body in sows, the fluids of the reproductive tract were analyzed using Gas chromatography. The samples were taken from various reproductive tract of 21 sows slaughtered. 1. Caprylic acid(C8: 0), capric acid(C10:0), lauric acid(C12:0), myristic acid(C14:0), palmitic acid(C16:0), plamitolele acid(C16:1), stearic acid(C18:0), oleic acid(C18:1), linoleic acid(C18:2) and arachidonic acid(C20:4) were found in the reproductive tracts of the sows, which made 10 kinds of fatty acid intotal. 2. Two kinds of polyunsaturated fatty acids, linoleic acid and archidonic acid were found inthe reproductive tracts. 3. Palmitic acid among saturated fatty acids and oleic acid among unsaturated fatty acids were the hihgest level in all of the reproductive tracts. 4. Palmitic acid, oleic acid and stearic acid showed higher rate with 44.89%, 23.69% and 14.36%, respectively, and lauric acid, capric acid, palmitoleic acid, arachidonic acid ad myristic acid showed lower rate with 0.62%, 1.13%, 1.65%, 1.97% and 2.24%, respectively in the reproductive fluid. 5. The highest level of arachidonic acid was found in the uterine horn. 6. The sum of the palmitic acid and oleic acid were 66.91%, 70.41%, 66.14% and 73.36% in the fluid of follicle, oviduct, uterine horn and uterine body, respectively. 7. The relative composition of arachidonic acid was higher during the follicular stage than during the luteal phase in the fluid of oviduct and uterine. 8. The long chain fatty acids such as the palmitic acid, stearic acid, oleic acid and linoleic acid showed higher relative compositions during the follicular phase(93.18%∼96.83%) than during the luteal phase(82.56%∼88.37%). 9. Caprylic acid, luric acid and palmitoleic acid were undetected in the fluid of all of the reproductive tracts during the follicular phase. Low relative compositions of capric acid, myristic acid andarachidonic acid were found during the follicular phase, while the low relative compositions (<5%)of capric acid, lauric acid, myristic acid, plamitoleic acid and arachidonic acid were found during the luteal phase.

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.

The different developmental stage embryos and oviductal and uterine fluids of rabbit were analyzed by 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), arachidic (C 20:0), arachidonic (C 20:4), docosahexaenoic (C 22:6) and lignoceric (C 24:0) acids were the common fatty acid constituents with little exception. In most of the samples palmitic, oleic, linoleic and arachidonic acids were observed in high concentration. Moreover, linoleic, linolenic and arachidonic acids were the three poly-unsaturated fatty acids in both type sample except day-1 oviductal fluids. Similarly, in both day-1 and day-2 oviductal and uterine fluids myristic, palmitoleic, stearic, linolenic, arachidic and docosahexaenoic acids were in less composition or undetected.

Pericarp of Zanthoxylum coreanum Nakai have been used as a crude medicine for the treatment of ozena, rheumatoid, nasal sinusitis, meno-xenia, dyspepsia, toothache, sore throat, pains in the limbs, etc. in Korea. A sterol fraction and two compounds, compound I and II were isolated from the roots, stems, leaves of Zanthoxylum coreanum Nakai. The sterol fraction was identified as a mixture of ${\beta}-sitosterol$ and campesterol. Compound I, colorless prismatic crystals, $C_{13]H_{13}NO_4$, mp. $175{\sim}177^{\circ}$, was proved to be skimmianine which is one of the alkaloids and compound II, $C_{14}H_{28}O_2$, mp. $53{\sim}55^{\circ}$, white powdered crystals was identified as myristic acid.

The structural changes of molecules on the water surface were measured by displacement currents and $\pi$-A isotherm. By using a theoretical equations we calculated charges($\Delta$Q) and dipole moment( $m_{z}$) of saturated fatty acids( $C_{12}$, $C_{14}$, $C_{16}$). The dynamic behavior of saturated fatty acid monolayers at the air/water interface was investigated using a displacement current-measuring technique coupled with the so called Langmuir film technique and also the dipole moment of the acids was determined.as determined.d.

국내에서 생산되고 있는 버터의 유리지방산 조성을 분석하기 위하여 silicic acid column chromatography 방법을 이용하여 버터로부터 직접 유리지방산을 분리 용출시켜 농축한 후 GLC로 분석하였다. 국산 버터 2종류 제품을 분석한 결과, 버터 A의 유리지방산 조성에 있어서는 $C_{18}$ 유리지방산$(C_{18_0},\;C_{18:1},\;C_{18:2}\;및\;C_{18:3})$ 함량이 52.83%로 가장 높았고, 그 다음으로 palmitic acid가 29.39%, myristic acid가 11.85% 함유되어 있었으며, 버터 B의 경우에는 $C_{18}$ 유리지방산이 47.50%, palmitic acid가 30.52%, myristic acid가 13.76% 함유되어 있었고, 그 외의 유리지방산은 소량씩 함유되어 있었다. 한편 함량면에서는 적지만 버터의 풍미에 중요한 영향을 미치는 것으로 알려진 butyric, caproic, capric 및 lauric acid의 농도를 분석한 결과, 버터 A에서는 각각 35, 10, 48, 60ppm, 버터 B에서는 각각 56, 11, 70, 126ppm이었다.

Synbiotics help to improve gut health by promoting the growth of beneficial bacteria while glyconutrients provide a source of energy for the gut bacteria and may also have immunemodulating effects. The aim of the present study was to assess the effect of this combination on fatty acid and meat quality characteristics of growing pigs. In a five-week experiment, 804 growing three-way crossbred ([Landrace × Yorkshire] × Duroc) pigs with an initial body weight of 31.90 ± 2.6 kg on average were assigned to two treatments: 1) CON (basal diet) and 2) TRT1 (basal diet + 0.3% glycozyme [synbiotics and glyconutrient]), each consisting of 402 pigs. The TRT1 groups showed significantly higher values of palmitoleic acid (C16:1), capric acid (C10:0), myristic acid (C14:0), lauric acid (C12:0), elaidic acid (C18:1, t), pentadecylic acid (C15:0), gondoic acid (C20:1), lignoceric acid (C24:0), and omega-6 : omega-3 in fat than the CON groups. Moreover, in the lean tissues of the pig, the levels of C12:0, C14:0, C17:0, and C20:1 were significantly higher in TRT1 than in CON. However, significant differences were not observed after glycozyme addition in pH, water holding capacity, cooking loss, longissimus muscle area, drip loss, meat color, and sensory evaluation parameters. To conclude, the positive results of the fatty acid composition indicate that glycozyme may be an effective pig feed additive.

본 연구는 비육한우 32두(거세우 16두, 암소 16두)를 대상으로(C-1구 거세우에게 일반사료 : C-2구 암소에게 일반사료 : T-1구 거세우에게 쑥 2% 첨가 : T-2구 암소에게 쑥 2% 첨가) 4개 처리구를 두고 14개월간(생후 14개월-27개월) 비육시험한 결과는 다음과 같다. 등심부위의 전단력과 보수성은 T-1구($3.20kg/0.5inch^2$, 54.32%)가, 가열감량은 C-2구(22.22%)가 다른 처리구보다 크게 높았다(p<0.05). 관능검사의 다즙성, 연도 및 향미는 처리구가 대조구보다 높은 경향을 보였고, 그 중에서도 T-1구(5.50점-5.20점)가 가장 높게 나타났다. Catechin 성분에서 총 카테킨 및 에피카테킨 성분은 처리구(0.43-0.46 mg/kg, 0.056-0.065 mg/kg)가 대조구(0.23-0.25 mg/kg, 0.031-0.032 mg/kg)보다 더 높게 나타났다. 지방산 조성에서 oleic acid은 47.56-48.45% 정도, palmitic acid은 28.86-29.67%, stearic acid는 9.92-10.82%, palmitoleic acid 및 myristic acid는 4.68-5.49%와 2.48-3.89%의 범위로서 처리간에 유의차가 없었다. 이상의 시험결과로 볼 때, 거세한우에 대한 쑥첨가는 육질의 관능검사(다즙성, 연도, 향미) 및 이화학적 특성(전단력, 보수성)에서 크게 향상되었다.
