  • Perilla is an excellent oil crop for linolenic acid production but still needs more research to improve grain yield and chemical properties. We tried to estimate the possibility for improving grain yield and its quality by applying nitrogen top dressing(4kg per 10a) at 5 days after flowering stage of perilla, using a cultivar Yujin. This study investigated the growth characteristics and seed quality. Nitrogen top dressing on the flowering stage has little affected on such traits as length, node number and diameter of main stem, and branch, cluster and capsules numbers per plant. But compared with standard cultivation as a control, top dressing showed more leaf chlorophyll content by 85%, higher 1000-grain-weight by 31%, and one day extension of maturing period; consequently, grain outyielded by 60% with 123kg per 10a. Seed chemical components also showed 33.3% protein and 48% oil contents that were 11.5% and 6.2% higher than those of control, respectively. Also by top dressing, saturated fatty acid (palmitic and stearic acid) decreased and linoleic acid among unsaturated fatty acids increased. It is concluded that nitrogen topdressing at late flowering stage promotes grain yield and quality of perilla.

  • In this study, functional and emulsifying properties of oil extracted by supercritical carbon dioxide from balloonflower(Platycodon grandiflorum A. DC) seeds were investigated. The oil was lower in total polyphenol content(8 mg/100 g), but higher in ${\alpha}$-tocopherol(14.15 mg/100 g), ${\beta}$-sitosterol(116 mg/100 g) and stigmasterol(8 mg/100 g) contents than seeds. Based on DPPH radical scavenging activity, the oil($IC_{50}=1235.5{\mu}g/mL$) showed similar antioxidant activity to the seeds($IC_{50}=1138.2{\mu}g/mL$). At 1%(w/w) lecithin, O/W emulsion with balloonflower seeds oil had turbidity, microscopic image, mean particle size and emulsion stability similar to emulsion with soybean oil, but had lower turbidity and emulsion stability and larger mean particle size than emulsion with perilla seeds oil. Its surface tension was similar to perilla oil emulsion.

  • Biodiesel produced from the reaction of methanol and triglyceride which is the main component of animal fats and vegetable oils is known for remarkable lubricity. In this study, the lubricity of 3 kinds of biodiesel came from vegetable oils such as soybean oil, palm oil, and perilla oil and 2 kind of biodiesel which were produced from beef tallow and pork lard were analyzed using HFRR (High frequency reciprocating rig). In HFRR test result, the lubricity of perilla and soybean's biodiesel was higher than other biodiesels. After analysis of biodiesel components by GC-MS and determination of the lubricity of pure biodiesel components using HFRR, it was found that a higher olefin content and long alkyl chaining biodiesel had an excellent lubricity property.

  • This paper examines the effects of dietary fats on the fatty acid composition and market enzyme activites during liver damage in 2-acetylaminofluorene treated rats. Weaning Sprague-Dawley male rats were fed the diet of beef tallow(BT source of sturated fatty acid) corn oil(CO source of n-6 fatty acid) and perilla oil(PO source of n-3 fatty acid) at the level of 15% fat. Ten days after feeding 2-acetylaminofluorene(2-AAF) was injected intraperitoneally twice every week at the level of 50mg/kg body weight for 7 weeks. Liver microsomal and cytosolic fractions were collected to determine the microsomal fatty acid composition lipid peroxide(malondialdehyde MDA) contents glucose 6-phosphatase(G6 Pase) activity cytochrome(Cyt) P-450 contents and cytosolic glutathione S-transferase(G6 Pase) activity cytochrome(Cyt) P-450 contents and cytosolic glutathione S-transferase(GST) activity. The fatty acid composition in microsomal fraction was reflected by different dietary fats. By 2-AAF treatment linoleic acids were increased regardless of the diet MDA contents were higher in CO group than it was in BT group. However 2-AAF treatment decreased MDA contents in all dietary groups. G6Pase activity of BT group was higher than those of the other gropus. CO group had the highest Cyt P-450 contents and 2-AAF treatment lowered Cyt P-450 contents only in CO gropu GST activites were higher in CO than in BT group whereas the enzyme activites were increased by 20AAF treatment in all dietary groups. These results suggest that dietary fats and 2-AAF treatment in all dietary groups,. These results suggest that dietary fats and 2-AAF treatment affect microsomal fatty acid composition The enzyme activities concerned with liver damage were influenced differently by dietary fats and 2-AFF treatment Although PO diet contains much more polyunsaturated fatty acids than CO diet PO diet doesn't cause more oxidant stress compared with CO diet in these data.

  • The antifungal activity of chemical substances from Artemisia annua were examined. Antifungal activity of aqueous extracts from A. annua was higher than that of essential oils in Fusarium oxysporum, whereas that of essential oil was higher than that of aqueous extracts in Aspergillus nidulans. The GC/MS methods were employed for the analysis and identification of phytotoxic substances from A. annua. Essential oil of some components were identified including thujone, terpineol, β-pinene, cienole, 2,4-hexndienal, camphor, citronellal, (-)-menthone, (1R)-(-)myrtenol, (S)-(-)-perilla aldehyde, perilla alcohol, 4-tert-buthylaniline, eugenol, isosafrole, isoeugenol and α-humulene. These results suggest that the chemical substances from A. annua such as terphenoids seem to be responsible for the allelopathic effect.

  • The present study was conducted to investigate the supplementation effects of $C_{18:2}$ rich-soybean oil or $C_{18:3}$ rich-perilla oil (7% of total diet, DM basis) for 12 weeks on plasma metabolites, fatty acid profile, in vitro lipogenesis, and activities of LPL and FAS in adipose tissue of sheep. The treatments were basal diet (Control), $C_{18:2}$ rich-soybean oil supplemented diet (SO-D) and $C_{18:3}$ rich-perilla oil supplemented diet (PO-D). All the sheep were fed the diets consisting of roughage to concentrate in the ratio of 40:60 (DM basis). Oil supplemented diets (SO-D and PO-D) slightly increased contents of triglyceride (TG) and total cholesterol (TC), proportions of both cis-9 trans-11 and trans-10 cis-12 CLA and TVA, but lowered (p<0.01) those of $C_{18:0}$ compared to the control diet. No differences were observed in the contents of TG and TC and proportions of fatty acids in plasma between supplemented oils. Oil supplemented diets slightly increased the proportions of cis-9 trans-11 and trans-10 cis-12 types of CLA in subcutaneous adipose tissue of sheep compared to the control diet. The rate of lipogenesis with acetate was higher (p<0.01) for intermuscular- and subcutaneous adipose tissues than that for intramuscular adipose tissue, while that with glucose did not differ among fat locations in sheep fed SO-D. No differences were observed in the rate of lipogenesis between substrates in all fat locations. The rates of lipogenesis with glucose increased only in the intermuscular- (p<0.01) and subcutaneous adipose tissue (p<0.005) compared to those with acetate. The rates of lipogenesis with acetate were the highest in the intermuscular and intramuscular adipose tissue of the sheep fed PO-D. Oil supplemented diets slightly increased the rate of lipogenesis with glucose for all fat locations. Supplementation of oils to the diet numerically increased the fatty acid synthase activity but did not affect the lipoprotein lipase activity in subcutaneous adipose tissue.
