Background: Safflower (Carthamus tinctorius L.) is a useful medicinal and oil crop in Korea. However, when safflower is cultivated, the flowering period overlaps with the rainy season, and seed maturation is poor. Therefore, this study aimed to use basic research data to develop superior varieties using agronomic characteristics and crossing method. Methods and Results: A total of 34 safflower germplasms were sown and their agronomic characteristics were investigated. Based on these investigations, the cultivar 'ui-san-hong-hwa' was selected as the mother plant, and 'Myanmar safflower' (Hsu Pan) was selected as the father plant. In addition, we developed a floret-protecting cap to cover florets after emasculation during the artificial crossing. When florets were protected by the cap, the seed setting rate increased in comparison to that in the non-covered florets. Conclusions: Agronomic characteristics can contribute to developing suitable varieties. The results suggest that the protection cap will be helpful in breeding without the floral organ drying. This study contributes an efficient breeding method to develop new safflower varieties.

Safflower, a draught and salt tolerant oil seed crop of Compositae family, has been cultivated around the world mainly as source of edible oils and dyes, where India, the USA, Mexico, Australia, and Ethiopia contributing about 85% of the production altogether. In this study we have characterized some selected morphological properties of safflower plant and determined the the total phenolic content (TPC) and fatty acid composition in seeds of 237 genetic resources. All the seed coats were white colored while the petals had red, yellow and white pigments. The yellow was the predominant petal color being recorded in 182 accessions followed by red occurring in 49 accessions. The petal color of 47 of the accessions changed with development while the 190 accession showed no change of color. The leaves are ovate to obovate, mostly with dentate (21 moderate and 205 weak) and few smooth (11) margins. The plant length, leaf length, and leaf width were ranged between 65.7 and 160.8 cm, 14.3 and 37.0 cm, and 3.3 and 12.1 cm, respectively. The TPC was determined using Folin-Ciocalteu method and fatty acid compositions were evaluated using gas chromatography. The TPC content ranged from 23.71 to 132.72 µgGAE/mg dried extract (DE). The seeds of safflower genetic resources accounted an average crude fat content of 26.25% (14.84 to 41.70%). The total fatty acid is mainly comprised of 71.72% linoleic acid (18:2) and 20.08% oleic acid (18:1) on average, the remaining palmitic acid (16:0), stearic acid (18:0) and linolenic acid (18:3) contributing 5.84, 2.23 and 0.15 %, respectively. The fatty acid composition of safflower seeds has shown great variability, where oleic and linoleic acid have a wide range of variation, from 9.23 to 83.35% and from 10.46 to 82.62%, respectively

A simple and rapid method was developed to prepare a large quantity of highly pure conjugated linoleic acid (CLA) chemically-synthesized from safflower seed oil (SSO). CLA-SSO(74.9% in purity) was synthesized from fresh SSO(79.9% of linoleic acid) by alkaline isomerization at 18$0^{\circ}C$. Urea(50g) and CLA-SSO (25g) were completely dissolved in ethanol (750ml) using a water bath(5$0^{\circ}C$) and followed by refluxing for 60 min. The resultant was cooled to room temperature and stored in a cold room (4$^{\circ}C$) for 24hrs. After removing the urea adduct by filtration, the filtrate was rotoevaporated under 4$0^{\circ}C$ and the residue was dissolved in hexane (200ml). The hexane extract was washed with distilled water (100ml$\times$3) and dried over sodium sulfate anhydrous. This urea treatment procedure was repeated three times. The purity of CLA recovered from the hexane extract was 95.0%. This method can be applied to prepare a large quantity of highly pure chemically-synthesized CLA (>0.5kg/a batch) from any plant oils containing high percentages (>70%) of linoleic acid.

Natural safflower oleosomes are small ($1{\sim}3{\mu}m$) spherical shaped "reservoir", inside which the seed stores triglycerides for use as a future energy source. The surface of the oleosome is covered with a high molecular weight ($20{\sim}24$ KDa) oleosin protein which has been demonstrated to have emulsification properties. Traditionally, oleosomes from oil bearing seeds such as safflower were simply crushed to liberate the oil within. Our patented DermaSphere technology allows for the isolation of oleosomes in the intact state. Once isolated, these materials can be used in skin care formulations to deliver the emolliency, occlusivity, and anti-oxidant effects typically associated with safflower oil. However, because of the presence of the emulsifying oleosin protein covering the spherical oil body, oleosomes have self-emulsification property as well as can emulsify other oil phase in typical oil-in-water (O/W) emulsion. The oleosomes can literally serve as the entire non-active portion of the oil phase of a typical skin care product. Most importantly, natural oleosomes can be loaded with other oil-soluble active materials and can therefore be used as delivery systems for improved cosmetic efficacies. Oleosomes can be loaded with various actives, such as fragrances, vitamins, inset repellents, and UV chromophores. The loaded oleosomes can be utilized to either protect the active ingredients within the formulation itself or to allow for control release of those actives over time.

Anti-wrinkle Effect of safflower (Carthamus tinctorius L.) seed extract (CTSE) was evaluated by determination of the anti-oxidation, collagen synthesis and elastase inhibition in normal human fibroblast. CTSE showed anti-oxidation and collagen synthesis ability as much as or greater than other phytoestrogenic compounds such as genistein or resveratrol. Consistent with collagen synthesis promotion, CTSE also showed inhibitory effect on elastase activity. In the human skin irritation test, 0.2％ CTSE did not show any adverse effect. These results demonstrate that CTSE can be useful as an anti-wrinkle cosmetic ingredient.

This study was conducted to determine the germination characteristics, oil contents and fatty acid compositions of the different safflower accessions. The safflower accessions had nearly the same germination period of about 12-13 days and the germination rate was more than 87.5%. Plant height grew until 84 days after seeding. The number of leaves did not increase after 70 days from seeding. The accessions had a difference of six loaves from 17 to 23 loaves. Flowering time had a difference of 11 days from 79 days after planting to 90 days after planting. The Jangsung accession had the shortest flowering time of 79 days after planting. In the characteristics of bearing fruit, the number of branches including main stem are from 4.7 to 8.8. The number of head flowers had nearly the same number of branches which were 4.8-8.9, numbers of seed per head flower were 29.3-49.1 and the weight of 100 seeds were 2.9-3.9 g. The crude fat content was 21.8-33.9％ and fatty acid content was 66.6-77.6% containing mostly linolenic acid. Oeic acid content was 9.2-16.5% and it contained palmitic acid, stearic acid, venin acid, arachidonic acid etc. Results of this study, the accession Jangsung, which had the shortest flowering time and had the most crude fat content, was observed to be the best accession for the breeding of safflower.

White Leghorn hens were fed a commercial formula feeds as a basal diet, which was supplemented with 3 types of plant oil safflower, evening primrose and pine seed, at the 10% level for 3 weeks. No significant changes was found between the basal diet and the oil feeding trials in the egg yolk cholesterol content, the laying rate, the egg weight, and the yolk weight, except the feed intake. In the fatty acid composition of the egg yolk lipid, however, the plant oil feedings to hens resulted in considerable increase of $C_{18:2}$ acid with a simultaneous decrease of $C_{18:2}$ acid ,and, consequently, followed by the improvement of balance with P /S and P /M /S ratio close to 1.0 and 1:1:1, which is known a desirable ratio for human health in lipid nutrition, respectively.

Relative content(% weight) of proteins, carbohydrates, lipids, and crude ashs in seed of korean green tea plant(Camellia simecis L.) are not different from those in seed of sunflower and safflower. However, the Camellia seed contains much higher crude saponin content(12.2%) than that of sesame(0.29%) or peanut(0.63%). It also contains 82% unsaturated fatty acids including oleic acid and contains tocopherol $(22\;{\mu}g/g,\;{\alpha}-form\;only)$ that is significantly less than of other oil-seed.

The purpose of this study was to examine whether conjugated linoleic acid and selenium supplementation in broiler chicken diets would be effective, enhance indices of immune status and body weight, and modulate serum lipid concentration. Forty Hyline brown chickens, 1 weeks of age, were divided into 5 groups of 8 chickens. Chickens were fed the experimental diets supplemented with 1% CLA (conjugated linoleic acid; Group 1), 1% CLA + selenium (Group 2), 1% safflower-seed-oil as LA (Group 3), 1% safflower-seed-oil as LA + selenium (Group 4) or nothing (Control) for 4 weeks. After 4 weeks, serum, liver, spleen and abdominal fat were taken. Measurement of total immunoglobulin were executed using sandwich ELISA. Weight ratio of liver to body showed that the group fed with CLA were significantly higher than the group fed with CLA + selenium. Weight ratios of spleen and fat to body showed no significantly differences. In concentrations of serum total cholesterol and HDL-cholesterol, the group fed with CLA showed significantly higher values than that fed with CLA + selenium. In concentrations of serum triglyceride and LDL-cholesterol there were no significantly differences between the treatment groups. In conclusion, supplementation of CLA with selenium protected hepatomegaly and reduced level of serum total cholesterol and HDL-cholestererol in chickens.

The effects of dietary sources of C18:2 n-6 or C18:3 n-3 fatty acids on the occurrence of conjugated linoleic acid (CLA) and time-dependent changes of free fatty acid fractions in rumen contents were investigated. Sheep (n=4) fitted with rumen fistula were used in a 44 Latin square design wxith each 14 d period. Sheep were fed one of four diets consisting of grass hay and concentrates in a ratio of 70:30. Dietary treatments were 100% concentrates (served as the control), and concentrates were replaced by safflower seed at 30% (SFS), safflower meal at 18% - safflower oil at 12% (SFO), and safflower meal at 18%-linseed oil at 12% (LNO). At the end of each experimental period, rumen contents from each sheep were collected before feeding and at 1, 3, 6 and 12 h after feeding. The levels of cis-9, trans-11 CLA in free fatty acid fraction were considerably increased in all treated groups relative to the control, but not significantly. The increase in cis-9, trans-11 CLA was slightly higher in SFS and SFO groups than group fed diet containing linseed oil. The level of cis-9, trans-11 CLA in free fatty acid fraction was reached to the maximum value at 1hr after feeding and, thereafter gradually decreased to near the value before feeding. The generation of trans-11 C18:1 was significantly higher in all treated groups than that of control. The level of trans-11 C18:1 was linearly increased after feeding of experimental diets, reaching the maximum value at 3 h. Feeding of diets containing polyunsaturated fats to sheep resulted in a marked increase in the levels of trans-11 C18:1 and a slight increase of CLA in free fatty acid fraction of rumen contents. Our results support that endogenous synthesis of CLA from trans-11 C18:1 may be involved the primary source of CLA in dairy product. (Asian-Aust.
