In this study, we evaluated the fatty acid composition and physiological activities of oils extracted from eight types of seeds, pepper (Capsicum annuum L.), green tea (Camellia sinensis L.), perilla (Perilla frutescens var. japonica Hara), peanut (Arachis hypogaea L.), cotton (Gossypium indicum LAM.), sesame (Sesamum indicum L.), walnut (Juglans regia L.), and safflower (Carthamus tinctorius L.). The composition and quality analysis showed that the oils were potentially suitable for foo-grade applications. The composition analysis showed that the oils were mostly composed of unsaturated fatty acids including linoleic acid and oleic acid. In 3T3-L1 adipocytes, green pepper, perilla, and peanut seed oils inhibited lipid accumulation, and green pepper, perilla, peanut, sesame, walnut, and safflower seed oils induced leptin secretion. These results show that the inhibitory effect of edible seed oils on lipid accumulation, and induction of leptin secretion may be useful for obesity management.

To develop new therapeutic materials to prevent hair loss and enhance hair growth, we developed a medicinal herbal complex extract (MHCE) using 23 herbs traditionally used in oriental medicine. Medicinal Herbal complex extract was consist of Angelica gigas Nakai, Psoralea corylifolia Linne, Biota orientalis Endlicher, and Eclipta prostrata Linne, Rehmannia glutinosa Liboschitz var. purpurea Makino, Ligustrum lucidum Aiton, Polygonum multiflorum Thunberg, and Sesamum indicum Linne, Sophora angustifolia Sieboldet Zuccarini, Angelica dahurica Benthamet Hooker, and Leonurus sibiricus Linne, Salvia miltiorrhiza Bunge, Prunus persica Batsch, Commiphora molmol Engler, Chrysanthemum indicum Linne, Boswellia carterii Birdwood, Panax ginseng C. A. Meyer, Cnidium officinale Makino, Albizia julibrissin Durazzini, and Corydalis ternata Nakai that have traditionally been used for treating hair loss, preventing gray hair, anti-inflammation, and blood circulation in oriental medicine. In addition, we examined the hair growth effect of MHCE in vitro and in vivo. In vitro, we evaluated the effects of MHCE on cultured HFDPC, HaCaT cells, and murine embryonal fibroblasts (NIH3T3 cells). Also, we evaluated the ability of MHCE to prevent gray hair on murine melanoma cells (B16F1 cells). The hair growth-promoting effect of MHCE in vitro was also observed in vivo using C57BL/6 mice. Our results showed that MHCE significantly increased the proliferation of HFDPC (175 % proliferation at $50{\mu}g/mL$), HaCaT cells (133 % proliferation at $20{\mu}g/mL$), and NIH3T3 cells (120 % proliferation at $50{\mu}g/mL$). MHCE also showed consistent melanogenesis in B16F1 cells (154 % melanin synthesis at $50{\mu}g/mL$). Moreover, MHCE showed potential for hair growth stimulation in C57BL/6 mice experiments (98 % hair growth area on 4 weeks). These results indicate that MHCE may be a good candidate for promotion of hair growth.

The objective of the study was to investigate growth pattern of capsule and grain to improve grain filling during the grain filling period in sesame. Growth patterns of capsule and grain from anthesis to maturity were measured and compared by different plant types. Growth of capsule length started to grow just after anthesis and recorded maximum point at 35 days after flowering. and then decreased gradually. Growth of higher part capsule was worse than lower and middle capsules. Capsule growth of 2 carpels 4 loculi type showed better than 4 carpels 8 loculi type and BTB (branch, 3 capsules, 2 carpels, 4 loculi) type showed good growth due to its small reduction of higher part capsule length compared to those of lower and middle parts. The order of growth of capsule length were considered to be center capsule in main stem> center capsule in branch> side capsule in main stem> side capsule in branch. Growth of capsule width also showed maximum at 35 days after anthesis and then reduced. The order of growth of capsule width were lower part> middle part> higher part. Higher part capsule width of 3 capsules 4 carpels 8 loculi type showed serious decrease at late reproductive growth stage same as those of capsule length. Fresh one thousand grain weight showed peak at 35 days after anthesis and then reduced. The order of grain growth were appeared as lower part> middle part> higher part. Growth of fresh one thousand grain weight of branch and side capsule were lower than those of main stem center capsule, and 4 carpels 8 loculi type was deeply decreased at late flowering time in higher part such as the growth of capsule length and width. BTB (branch, 3,2/4) type didn't show much decrease in higher part fresh grain weight compared to those of other plant types in spite of its profitable character of lots of sink capacity. BTB type appeared to be ideal for improving grain filling and yield productivity in growing sesame in Korea.

The development of sesame varieties which contain high contents of lignan compounds has been progressed in Korea. This study was carried out to get the basic information for the breeding of high quality sesame varieties and the development of health functional food sources using lignan compounds from sesame. The contents of sesamin and sesamolin were $4.08\pm1.74$ and $2.47\pm0.68mg/g$, respectively, from sesame cultivated in 2002 and those were $4.08\pm1.51$ and $2.48\pm0.69mg/g$, respectively, from sesame cultivated in 2003. The content of sesamine was high in the order of Danbaek (6.22 mg/g), Seongbun (5.94 mg/g), Namda (5.83 mg/g), and Naman (5.59 mg/g) producted in 2002 and Seongbun (6.27 mg/g), Dasak (5.53 mg/g), Danbaek (5.50 mg/g), chinbaek (5.45 mg/g), and Seodun (5.41 mg/g) producted in 2003. The content of sesmoline was high in the order of Hwangbaek (3.27 mg/g), Seongbun (3.26 mg/g), Annam (3.22 mg/g), Hanseom (3.17 mg/g), and Danbaek (3.16 mg/g) producted in 2002, and Seongbun (3.21 mg/g), Seodun (3.14 mg/g), Pungan (3.10 mg/g), Naman (3.09 mg/g), and Danbaek (3.04 mg/g) producted in 2003. The contents of sesamin and sesamolin of Yangbaek, which has used as a standard variety for sesame breeding, were relatively lower than in any other varieties. These resluts suggest that Yangbaek is not the proper variety as a standard variety for development of high quality sesame. In conclusion, proper good variety as a standard variety for sesame breeding must be determined after careful consideration on the major quality factors including crude oil and lignan compounds as well as agricultural characteristics to develop high quality sesame varieties containing high contents of lignan compounds.

The objective of this study was to investigate the effect of sesame monoculture and sesame in rotation (SR) with maize. soybean. barley or rye on reduction of injury by continous cropping in sesame. Field studies were conducted for 3-years (1995~1997) at the experimental field of the Crop Experiment Station. Compared to CS (continuous sesame). SR treatments turned out to keep more organic matter and higher exchangeable cation concentrations in soils. BS (barley and sesame in a 1-year rotation) and RS (rye and sesame in a 1-yea r rotation) treatments had significantly greater available $P_2O_5$ contents in soils than CS, MS (maize and sesame in a 3-year rotation) and SbS (soybean a nd sesame in a 3-year rotation). The pH of the soils under different treatments were not significantly different. SR treatments exhibited significantly lower bulk density and higher pore space than CS. Soil microbial biomass C (SMBC) and N (SMBN) were determined by the chloroform fumigation-extraction method. SMBC and SMBN were significantly higher in soils under BS and RS than those under CS, but only during the 1 year of monitoring. MS and SbS treatments resulted in higher SMBC and SMBN than CS. The occurrence of injury by disease of sesame is the important primary factor of injury by continous cropping, but the disease occurrence with rotation did not decrease in th is experiment. Under CS treatment, the growth and grain of sesame was significantly lower than those under other treatments. Compared to CS, the increments of grain yield of sesame were 68, 63, 57 and 51% for MS, RS, SbS and BS, respectively in the first harvest. In the second harvest, they were 24% for MS, 28% for RS, 20% for SbS and 19% for BS. The average increase ratios during the two years were 41, 41, 34, and 33% for MS, RS, SbS and BS, respectively.

Combining ability and heterosis for $F_{1}$ population obtained $5{\times}5$ half diallel cross in sesame were estimated for six quantitative characters. The parental varieties used for diallel cross were Yangbaek and Ansan of normal type, Suwon 177 and 195 of placenta adhesion type (PA) and SIG960320-5-1-1 of indehiscent type (ID). PA and ID type are shattering-resistant sesames and Yangbaek and Ansan are shattering sesames. The high heterosis of $F_{1}$ hybrids was expressed in the number of capsules per plant (NC), grain yield per plant (GY) and number of branches per plant (NB). Shattering.ate (SR) showed high positive heterosis toward increase of seeds shattering in all the combination of $F_{1}$ generation which was presumed because the characters connected with shattering resistance of seeds were governed by recessive gene. At the analysis of combining ability, highly significant general combining ability (GCA) effects were observed on all the characters in $F_{1}$ generation, significant specific combining ability (SCA) effects were observed on the NC, GY and SR. GCA variances were greater than SCA variance, which suggested that additive gene effects were greater than other nonadditive gene effects. Considering the estimated GCA effects, Suwon 195 (PA type) was found to be good parent for SR and GY, SIG960320-5-1-1 (ID type) was poor for GY and plant height. SCA effect for NC was great in Yangbaek/Suwon 195, SCA for GY was great in Ansan/SIG960320-5-1-1, and SCA for decrease of SR was great in Ansan/Suwon177.

The habit of anthesis and maturity of sesame were investigated as a basic research for the improvement of high-yielding varieties and cultural practices. Eight different plant types were identified using typical cultivars among gene pool grown in Korea. Non-branching, Monocapsule, Bicarpels quadriloculi (NMB) type showed higher ratio for capsule setting compared with Non-branching, Monocapsule, Quadricarpels octoloculi (NMQ) type. Non-branching, Tricapsules, Quadricarpels octoloculi(NTQ) type presented lower ratio for capsule setting than non-branching, tricapsules, bicarpels quadriloculi(NTB) type. The number of flowers by flower setting position was the highest on lower part, intermediate on middle part, and the lowest on higher part in NMB and NTB type. However, the number of flowers was the highest on middle part, intermediate on lower part, and lowest on higher part in NMQ and NTQ type. BMB type appeared to have the highest ratio for capsule setting when compared with the other plant types. BTB type with many flowers and capsules exhibited higher percentage for capsule setting than BTQ type with lowest capsule setting percentage. Capsule setting percentage of branch appeared to be lower than that of main stern in the branching type. The branching type had more flowers and capsules than non-branching type. Tricapsules type had more flowers and capsules per plant than monocapsule type, and bicarpels quadriloculi type had more than quadricarpels octoloculi type. However, capsule setting ratio in non-branching type was higher than in branching type. The ratio was higher in monocapsule type than in tricapsules type. Bicarpels quadriloculi type had higher ratio of capsule setting than quadricapels octoloculi type. Number of capsules per plant and capsule setting ratio are supposed to be dominated by shape of capsule (number of carpels and loculi), not by branching or number of capsules per axil. The order of number of capsules per plant was as follows; BTB, BMB, NTB, BTQ, BMQ, NTQ, NMQ, and NMB types. However, the order of capsule setting ratio was as follows: BMB, NMB, NTB, NTQ, NMQ, BMQ, BTB, BTQ types. Consequently, branching, tricapsules, bicarpels quadriloculi(BTB) type was considered as a sourse of breeding for high yielding varieties by introducing the genes govering BMB type with one capsule per axil which has high capsule setting ability.

This study is on the effect of oil seed by-products added to Chungkukjang. For this, we designed three cases: Chungkukjang was added in with defatted sesame flour before fermented (DSFBF), added with defatted sesame flour after fermented (DSFAF) and with no adding (control). In each case, the common ingredients and the active antioxidant ingredients were examined and compared and the effects were analyzed. According to microanalysis result, carbohydrate content Chungkukjang the DSFAF 24.97%, control 23.86%, DSFBF Chungkukjang 20.21% as compared to control and Chungkukjang DSFAF relatively low carbohydrate content. The moisture contents in DSFBF (55.98%) or DSFAF (52.83%) were higher than that in control (48.89%). Chungkukjang crude ashes in DSFBF (1.48%) or DSFAF (2.41%) were much lower than in control (6.45%). The proportions of crude lipid in DSFBF (3.30%) or DSFAF (3.93%) were higher than in control (1.77%) by about 2%. As for crude protein, the percentage in DSFAF (15.86%) was lower than that of DSFBF (19.03%) or of control (19.03%). There was no meaningful difference in biological activity measurement as total phenolic contents were 1.26 mg/mL in DSFBF, 1.14 mg/mL in DSFAF and 1.26 mg/mL in control. But electron donating ability was meaningfully more active in DSFBF (21.30%) than in control (20.24%). The superoxide dismutase (SOD)-like activity in DSFBF (68.48%) was twice higher than in control (34.01%), which may imply that DSFBF contain some ingredients that can scavenge superoxide anion radically. In hydroxyl radical scavenging activity, DSFAF scores 96.87%, which is the highest with 96.40% in DSFBF and 95.73% in control. Relative antioxidative effects in DSFBF was 47.92%, which is comparable to 47.06% in control. As a result of extraction and quantitative HPLC analysis of sesamin and sesamolin extracted from the samples, DSFBF contained 3.04$\pm$0.21 mg/g of sesamin, which is meaningfully higher than 2.41$\pm$0.14 mg/g in DSFAF. Content of sesamolin was higher in DSFBF (1.36$\pm$0.09 mg/g) than DSFAF (1.12$\pm$0.07 mg/g) or in control. We can conclude that biologically active and effective ingredients could be found more in DSFBF than in DSFAF or in control. This study conveys not only the meaning that oil seed by-products can be used as an ingredient for making Chungkukjang functional food, but also the possibility that oil seed by-products themselves could become excellent functional food.

The aim of this study was to investigate method validation for determination of sesamol, sesamin, and sesamolin in non-fermented sesame and fermented sesame by bioconversion. For validation, the specificity, linearity, precision, accuracy, limits of detection (LOD), and quantification (LOQ) of sesamol, sesamin, and sesamolin were measured by HPLC. Linearity tests showed that the coefficients of calibration correlation ($R^2$) for sesamol, sesamin, and sesamolin were 0.9999. Recovery rates of lignan contents in non-fermented and fermented sesame were high in the ranges of 100.27~115.10% and 98.43~114.90%, respectively. The inter-day and intra-day precisions of sesamin and sesamolin analyses for non-fermented and fermented sesame were 0.27~1.94% and 0.25~0.69%, respectively. The LOD and LOQ were $0.23{\sim}0.34{\mu}g/g$ and $0.70{\sim}1.03{\mu}g/g$, respectively. These results indicate that the validated method is appropriate for the determination of sesamol, sesamin, and sesamolin.

This study was conducted to obtain basic informations for breeding and improving cultural practices of sesame (Sesamum indicum L.) through investigation of several agronomic characters of 82 major varieties plants in April 20, May 15 and June 20. Stem diameter and plant height were largest in early planting(April 20). On the contrary, they were smallest in late planting(June 15). Therefore, the later planting, the poorer the vegetative growth on the basis of stem diameter and plant height. Number of capsules per plant and number of grains per capsule were 88 and 54, respectively, in the early planting, while they were decreased to 25 capsules and 40 grains in late planting. The percentage of ripeness and 1000 grain weight 78 and 2.3g in the April 20planting while they were 58% and 2.1g in June 20 planting indicating the later planting, the lower the ripeness. Grain yield per m1 in April 20 and June 20 planting was 112 and 18g respectively. Consequently, grain yield significantly decreased as planting delayed. On the basis of the vegetative and reproductive growth, varieties could be classified into early, conventional, late and indetermediate planting adapted groups. The major yield components were highly and postively correlated with accmulated sunshine hours and temperatures confirming that grain yield was closely related with sunshine and temperature. Among the varieties tested, Gurye and Local 135 had more than 150 capsules. Haenam and Woogang had more than 75 grains per capsule. Since grain yield oflate planted sesame were significantly different among the varieties, breeding of sesame for after barly cropping would be more effective under late cultural condition of after barly.
