This study investigated the antioxidant content and oxidative properties of roasted sesame oil during manufacturing and storage at $25^{\circ}C$ in the dark for 18 months. The manufacturing steps included pressing of the roasted sesame seeds, and then three filtering steps. Filtering decreased the oil viscosity, but increased free fatty acid content. The peroxide value (POV) was not affected by filtering. Sesamin, sesamolin, and tocopherol levels were significantly higher in the $3^{rd}$ filtered oil as compared to the other oils; however, sesamol content was reduced. The roasted sesame oil oxidized slowly during storage at $25^{\circ}C$ in the dark, and there was no POV change up to 9 months of storage. The levels of sesamol, sesamin, sesamolin, and tocopherols in the oil decreased with storage time, and the tocopherol decomposition rate (-3.04%/month) was higher than that of total lignan compounds (-1.06%/month). Therefore, these results suggest that tocopherols have priority over lignan compounds in performing as antioxidants in roasted sesame oil during storage.

Researches on industrial crops in Korea before 1962 were concentrated on fiber crops such as cotton, kenaf, hemp, ramie and flax. Then research works on oil crops, sugar crops and other high income crops were followed. However, no land is shared for the production of kenaf, flax, sugar beet, sweet sorghum and sunflower at present in Korea, while the cultivation of cotton, hemp, ramie and mat rush is decreasing continuously to the marginal point. At present researches are emphasized on oil crops such as seasame, peanut and perilla and high income medicinal herbs of which cultivating acreages are increasing. Numerous varieties were released as a result of active breeding works on industrial crops since 1962, i.e. 3 sesame varieties including "Suweon 21", 3 peanut varieties including "Seoduntangkong", and 6 rape varieties including "Yudal" in oil crops, one cotton variety "Mokpo 7", one hemp variety "MS4-1", and one kenaf variety "Suweon 2" in fiber crops, and two stevia varieties "Suweon 2" and "Suweon II" in sugar crops. Quality improvement of rape seeds and development of hybrid rapes utilizing male sterile lines are the most significant results of breeding works, while the establishment of vinyl mulching cultivation of sesame and peanut are the most successful results in agronomic researches during the last 20 years.re the most successful results in agronomic researches during the last 20 years.

Sesame (Sesamum indicum L.) is a rich source of edible oil most commonly it is used as a food product mainly in bakeries and also use as a common source of oil in daily kitchen needs. Due to the presence of some special phytochemicals like proteins, fibers, oil, minerals and antioxidants it is highly used for medicinal and therapeutic purposes. It is a good source of energy and act as an antiaging agent. Its seeds are used as Anti-helmintic, antihypertensive, antimicrobial, cytotoxic and Hepatoprotective but its seed coat which is a byproduct of sesame and a cherished source of fibers is normally use for animal feedstuff. In Unani system of medicine it is used both as drug & diet (dawa wa ghida). In classical Unani literature it is indicated in various disorders like Asthma, Dry Cough, Gastritis (due to any drug, excessive use of alcohol), Dryness of Intestine, Dryness in throat, Renal Stone, Bleeding Piles, Amenorrhea, Retention of urine, Dysuria, Orchitis, Sexual Debility, Anorexia. The present review article, an attempt have been made to compile all the pharmacological and Pharmacognostical characters of Sesamum indicum with special reference to Unani literature.

This study was conducted to develop soybean paste sauce with walnuts and sesame seeds and apply it to cooked spinach to examine the applicability of the sauce. Two factors of soybean paste sauce, soybean paste and glutinous rice paste, were need to decide the quantity of the ingredients. Nine soybean paste sauces were produced with various compounding ratio of soybean paste and glutinous rice paste, and color, viscosity and sensory evaluations were performed. Sensory evaluations were measured by 7-point Likert scale. Color($4.08{\pm}1.22$), taste($4.72{\pm}1.24$), viscosity($4.96{\pm}1.39$) and overall quality($4.24{\pm}1.51$) of the sample(soybean paste 400 g, glutinous rice paste 400 g) got the highest scores. Therefore, the sample(soybean paste 400 g, glutinous rice paste 400 g) was applied to cooked spinach. Cooked spinach using developed sauce and cooked spinach using general soybean paste were prepared and performed sensory evaluation. As a result, all sensory items score of cooked spinach using developed sauce were higher than that using general soybean paste. Especially, taste($4.96{\pm}1.15$) and overall quality($0{\pm}1.16$) of cooked spinach using developed sauce were significantly higher than taste($4.38{\pm}1.53$) and overall quality($3.56{\pm}1.53$) of cooked spinach using commercial soybean paste(p<0.05). Consequently, the applicability of soybean paste sauce using natural seeds was confirmed.

This study was carried out to analyse the nutrient composition of grape seeds and to assess as a plant oil source. Mean values of nutrient contents were as follows: moisture 10.1%, crude protein 11.7%, crude fat 29.7%, crude ash 2.53%, total sugar 4.38 ${\mu}g/mg$, and reducing sugar 3.96 ${\mu}g/mg$. Linoleic acid was the most prominent fatty acid, showing 66.15%, and followed by oleic acid > palmitic acid > stearic acid. Mean contents of neutral-, glyco-and phospholipids were 85.4%, 6.50%, and 8.06%, respectively. Mean saponification value of crude fat was 187.5, showing elevated value than that of perilla oil. Antioxidative capacity of grape seed oil was marked by 12 and 50% higher values than those of perilla or sesame oils. Regardless of storage conditions, grape seed oil showed more lowered P.O.V than perilla and sesame oils. P.O.V of grape seed oil treated at $150^{\circ}C$ showed a lower value than those of perilla and sesame oils. The stability against oxidation may be related with the antioxidant substances contained in the grape seeds.

This study was conducted to investigate the total lignin content and anti-oxidant activity in extracts of defatted sesame seeds (DSS) fermented with 15 strains of Bacillus subtilis. The anti-oxidant activities of DSS were analyzed both before and after fermentation. The total lignan content of the DSS extracts fermented with BCH3678 (1,613.8 mg/l) and BCH3572 (1,599.5 mg/l) were relatively high compared to other strains. Anti-oxidant activity was determined according to phenolic compound and flavonoid content and DPPH radical scavenging rate; the highest total phenolic compound content was provided by the DSS with SRCM103716 at 2,803.3 mg GAE/g which returned total flavonoid content of 1,553.1 mg/g as strong correlation of its anti-oxidant activity. The DSS extract fermented by SRCM103716 at 37℃ for 24 hr showed the highest DPPH scavenging rate at 66.5%. The fermented DSS extracts, regardless of strain, demonstrated higher anti-oxidative activity than the unfermented control, and these results suggest that such extracts could be useful as a potential source of bioactive compounds.

A greenhouse experiment on the Sr-90 uptake by peanut and sesame was conducted through pot cultures on a sandy loam soil of pH 6.35 treated with Sr-90 in 5.2 and 31.2Bq per gram. The rate of Sr-90 transfer from soil to each plant part, the ratio of Sr-90 concentration in the part to the concentration in soil, and the patterns of their temporal changes were not, on the whole, significantly different between the two treatments. About 0.7 and 0.5 % of Sr-90 in soil transferred to all the mature plants of peanut and sesame, respectively, with the radioactivities in their roots not counted. Only 4% and less than 15% of Sr-90 absorbed by peanut and sesame, respectively, translocated to their seeds. Both crops showed the highest Sr-90 concentration in the leaf and the lowest in the seed. At maturities, the concentration ratio in dry seed was 0.4 in peanut and 3.3 in sesame and that in dry leaf was 12.5 and 10.7, respectively. Sr-90 concentrations in the top 15 cm soil after harvests averaged about 80 % of the concentrations at starting. Sr-90 uptake resulted in neither growth inhibition nor yield decrease.

This study was conducted to investigate the effects of night illumination on the growth and yield of sesame(Sesamum indicum) and perilla(Perilla frutescens). Stem length and height of the first pod in sesame increased, whereas number of branch was reduced and flowering date and maturing date delayed as light intensity of night illumination increased. Number of capsules per plant, ripening ratio and seed yield of sesame were reduced as light intensity of night illumination increased. Yield reduction was greater in Ahnsankkae than in Sodunkkae. Number of nodes increased under night illumination in perilla. Two test cultivars showed reduction in number of branch at 6~10 Lx(22 ㎽ m$^{-2}$ ) intensity of night illumination, even though there was a variation between cultivars. Perilla was sensitive to night illumination far flowering and ripening. Flowering date was delayed by 21 to 28 days at 6~10 Lx intensity of night illumination. Number of flower clusters, number of seeds per flower cluster, and 1,000-seed weight in perilla were significantly reduced and seed yield was reduced by 89 to 98% at 6-10 Lx intensity of night illumination.

To estimate the responses of sesame plant in growth and yielding traits to different soil drainage conditions, a pot trial was conducted by using of sesame variety "Suweon-9" were introduced with 5 different mixing combinations of clay and sea-sand soils as 0:100, 25:75, 50:50, 75:25, and 100:0 percents in volumetric ratio. Also two irrigation methods as 20mm/6 days interval and 10mm/3 days interval were detected. As a result, water drainage was linearly decreased with increament of clay contents. And the excess drainage condition(such as pure sand soil) required more irrigation, however in crop growths, no significant differences among various soil drainage conditions except the pure sand were recognized. On the other hand, number of capsules per plant, among other yielding components, was most contributed factor to the yield, which was effectively given from the soil mixed with clay and sea-sand as 75% and 25%, respectively. Therefore, much similar responses were also detected from the seed yields per a sesame plant. However, the number of seeds per capsule and maturity function were more effectively composed under the soil mixed with clay and sea-sand as 25% and 75% respectively better than under the soil of 75% and 25%. As a conclusion, the yielding responses of sesame plant was advanced more effectively at the soil conditions of water conserved type (e.g. 25%/75% in clay/sand ratio) than of water-draining type (e.g. 75%/25% in clay/sand ratio).nd ratio).
