This study was carried out to investigate the effect of the feeding mixture of linesed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hypprlidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter, and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic durgs for 2 weeks. Analysis of the lipid component and the fatty acid composition of the liver showed following results. Concentration s of the total cholesterol and phospholipid in liver were significantly higher in group 2 (olive oil 12.0%) and lower in the other groups than in the control group, especially lower in groups 3 (cholestyramine 2.0%) and 9 (sunflower seed oil 12.0%) . Concentration of triglyceride was lower in the other groups except group 4 (liparoid), especially lowe rin group 9 than in the control group. In the fatty acid composition of liver lipids, C18:2 was the major fatty acid. Contents of n-6 PUFA increased , while those of n-3 PUFA decreased in groups composition of the test lipids. From the data on concentration s of total cholesterol. Phospholipid and triglyceride in liver, we concluded that the feeding mixed with 3.0% lard and 12.0 % sunflower seed oil were most effective for the improvement of the live lipids. The fatty acid composition in liver lipids were affected by the fatty acid composition of the test lipids.

The aim of this field experiment was to investigate the possible effects of mepiquat chloride (TE) and trinexapac-ethyl (MC) on oil composition, seed yield and endogenous gibberellins content of flax cultivar. Foliar application of plant growth retardants mepiquat chloride (0.897, 1.794 and 2.691 kg a.i. $ha^{-1}$) and trinexapac-ethyl (0.756, 1.512 and 2.668 kg a.i. $ha^{-1}$) had significantly increased seeds ripening rate and seed yield. In contrast, plant height was decreased by foliar application of MC and TE. The application of MC significantly increased seed oil yield (730 kg $ha^{-1}$ by 27.0%) compared to the control. Seed and oil yield, and unsaturated fatty acids (oleic acid, linoleic acid and linolenic acid) were increased by foliar application of MC.

This study was to investigate the chemical composition and biological activities of Pinus Koraiensis seed. The oil, moisture, ash, crude protein, and carbohydrate contents of P. Koraiensis seed were 58.21, 7.84, 1.56, 14.26, and 18.13%, respectively. The ratios of essential amino acid and nonessential amino acid against total amino acids were 36.6 and 60.3%, respectively. The saponification value of seed oil was 166.8 mg KOH/g oil. Among various fatty acids, the linoleic acid content was the highest, 35.5%, which was approximately 72.6% of polyunsaturated fatty acid. The ethylacetate extract of P. Koraiensis seed had the highest DPPH radical scavenging activity (62.8%) at 7.0 mg/mL, followed by hexane extract, methanol extract, and hot water extract. The maximum nitrite scavenging activity was obtained 59.3% at pH 1.2. The total phenolic concentration of ethylacetate extract was 98.7 mg/g, approximately 4.8 folds higher than that of the hot water extract. The maximum inhibition activities of elastase using ethylacetate extract and collagenase using hexane extract were 58.8 and 40.7%, respectively. These results indicate that P. koraiensis seed extract could be applied to present the possibilities of industrial applications for the developments of cosmetics.

콩단백질의 황 아미노산함량은 가축 영양학상 중요한 위치를 차지하기 때문에 신계통이 가져야만 할 필수조건일지도 모른다. 콩 계통간에 저장단백질의 유전적변이가 존재한다면 이는 기존의 육종방법을 통하여 콩의 종자단백질 구성성분을 유전적으로 변경하여 품질을 개량할 수 있는 가능성을 시사하고 있다. 본 연구는 여러 문헌에 보고된 콩종자 저장단백질의 돌연변이 계통들을 선별하여 콩단백질의 품질을 향상시키기 위한 육종 재료로서의 가능성을 평가하기 위하여 실행되었다. 수집된 돌연변이 계통들은 저장단백질의 또 다른 특성을 나타내었다. 그 돌연변이 계통들 중에서 Keburi(P.I.417016), Keburi(P.I.506817), P.I.154608-1 등은 황 아미노산 함량이 상대적으로 다른 돌연변이 계통보다 높은 1.9, 2.1, 1.8%를 나타내었으며, 이는 7S 단백질인 ${\alpha}$ ', ${\alpha}$ , ${\beta}$단백질 함량이 상대적으로 낮기 때문인 것으로 나타났다. 그러므로 그 돌연변이 계통들 중에서 Keburi(P.I.417016), Keburi(P.I.506817), P.I.54608-1 등은 황 아미노산 함량을 향상시키기 위한 중요한 육종재료로, 그 외 돌연변이 계통들은 다른 용도의 육종 재료로 이용할 수 있을 것으로 추측된다.

Objectives: The chemical composition of cactus pear seed oil (Opuntia ficus-indica [L.] Mill.) was analyzed in terms of its fatty acid composition, tocopherol content, phenolic identification, and the oil's phenolic-rich fraction antioxidant power was determined. Methods: Fatty acid profiling was performed by gas chromatography coupled to an FI detector. Tocopherols and phenolic compounds were analyzed by LC-FLD/UV, and the oil's phenolic-rich fraction antioxidant power was determined by phosphomolybdenum, DPPH assay and β-carotene bleaching test. Results: Fatty acid composition was marked by a high unsaturation level (83.22 ± 0.34%). The predominant fatty acid was linoleic acid (66.79 ± 0.78%), followed by oleic acid (15.16 ± 0.42%) and palmitic acid (12.70 ± 0.03%). The main tocopherol was γ-tocopherol (172.59 ± 7.59 mg/kg. In addition, Tyrosol, vanillic acid, vanillin, ferulic acid, pinoresinol, and cinnamic acid were identified as phenolic compounds in the analyzed seed oil. Moreover, the oil's phenolics-rich fraction showed a significant total antioxidant activity, scavenged DPPH up to 97.85%, and effectively protected β-carotene against bleaching (97.56%). Conclusion: The results support the potential use of cactus pear seed oil as a functional food.

The seeds of 16 domestic plants were studied for their moisture, total lipids and fatty acid composition. Of the 16 seeds, chestnut, corn, mungbean and ginko nut yielded less than 9% by weight of total lipids compared to others that gave 20-73%. The identified fatty acids from the seed lipids ranged from lauric acid (12:0) to lignoceric acid(24:0). It was intended in this study to classify the seed lipids according to their major fatty acids: Group t-Oleic acid; Group 2-0leic acid and linoleic acid; Group 3-linoleic acid; Group 4-linolenic acid ; Group 5-erucic acid ; Group 6-ricinoleic acid. The saturated fatty acid content of mungbean (33%) was the highest among the seed lipids studied. The highest value for the P/S fatty acid ratio(10) was in perilla.

This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$-6) content was negatively correlated (r=-0.217＊) with linolenic acid($\omega$-3) content.
