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.

Background: To obtain useful safflower resources for breeding and research of functional materials, the present study was conducted to determine fatty acid compositions and antioxidant activities of 281 safflower accessions collected from East Asia including South Korea. Methods and Results: Lipid contents and fatty acids compositions were evaluated using soxhlet extraction and gas chromatography, respectively. A antioxidant activities were analyzed using a spectrophotometer. The evaluation range of safflower accessions showed very wide variation. In terms of lipid contents, the China accessions were higher than the collection from other regions, whereas antioxidant activities did not differ among regions. The result of the principal component analysis showed that the first and second principal component cumulatively explained 90.6% of the total variation. In clustering the safflower accessions, the tree showed four major clades. Group II (16 accessions) was high in lipid content, oleic acid and linoleic acid, whereas group III (50 accessions) exhibited higher antioxidant activities than other groups. Conclusions: It was recommended that the China collections be utilized as a useful resource for research on functional oil materials. These results provided valuable information for safflower breeders and researchers of functional food.
Safflower (Carthamus tinctorius L.) is a thistle-like annual plant mainly grown in dry hot climates as an oilseed or birdseed. Traditionally, the oil has mainly been sold in the health food market because it is unsaturated having high linoleic and oleic acid levels. With increased health consciousness in recent years, the oil quality has become a more general health issue. This study was designed to understand whether safflower seed powder has positive effects on the fracture healing in rats. Simple transverse fracture of rat fibula was made with a rotating diamond disc saw. The histologic changes of rats were observed with a scanning electron microscope. The fractured fibulae showed a complete fusion at the fracture site in the 4th to 5th week after a simple transverse fracture. Administration of safflower seed powder facilitated the speed of histologic changes without affecting qualitative changes. These results suggest that safflower seed powder nay have substances that help the fracture healing process.
Response surface methodology was used for monitoring and optimizing the extraction conditions of campesterol, stigmasterol, ${\beta}$ -sitosterol, and total sterols from the safflower seed. The conditions of phytosterol extraction were optimized by using central composite design with the temperature(35∼75$^{\circ}C$, X$_1$), the time (1∼11hr, X$_2$), and the preheating temperature(60∼100$^{\circ}C$, X$_3$) as three variables. The extraction conditions for maximum campesterol content were 59.01$^{\circ}C$(X$_1$), 2.88hr(X$_2$), and 75.04$^{\circ}C$(X$_3$). But stigmasterol, ${\beta}$ -sitosterol and total sterols were not significantly different under designed extraction condition in this study. Besides, oil was extracted from safflower seed at various conditions and yields were 23.44% at 35$^{\circ}C$ and 20.05% at 80$^{\circ}C$, respectively. Total tocopherol content increased from 0.172% to 0.207% as the extraction temperature increased from 35$^{\circ}C$ to 80$^{\circ}C$. A structured lipids(SL) was synthesized enzymatically by extracted safflower oil and conjugated linoleic acid(CLA). After 24hr reaction, 31.79 mol% CLA was incorporated into the extracted safflower oil.

Deep-fat frying is a common cooking practice. There has been considerable concern regarding the mutagenic and carcinogenic potential of thermally oxidized oils. Studies on deep-fried foods so far have revealed not much on the mutagenicity of the oils in the foods. Therefore, in the present study, it was attempted to investigate the mutagenicity ofthe thermally oxidized safflower oil. Oil was heated in a home-fryer at a temperature of 180$\pm$3$^{\circ}C$ for 48 hours. Oil samples were taken at 0, 8, 16, 24, 32, 40 and 48 hours of heating, respectively. Each sample was used to study the changes in peroxide value (POV), acid value (AV), iodine value (IV), conjugated dienoic acid (CDA) content, %, and fatty acid composition. Another series of samples were fractionated into non-polar and polar fractions by column chromatography. The mutagenicity of the samples taken from the thermally oxidized oils, as well as the non-polar and polar fractions of the thermally oxidized oils, was investigated with the Ames test. The Ames test was carried out with and without metabolic activation. Bacterial tester strains used in the present study were the histidine auxotrophic strains of Salmonella typhimurium TA100, TA1535 and TA102 were used for the detection of base pair mutations, and TA98 and TA1537 for frame shift mutations. Each series of samples was dissolved in tetraphydrofuran (inhibitor-free) and tested at doses ranging from 0.05 to 5 mg/plate. None of the oil samples taken during the 48 hour oxidation period showed any mugagenic activity. This was the case, even after the activaton with 59 mix. Also, none of the polar and non-polar fractions showed any mutagenic activity on all the strains tested.

Much attention has been given to the role of safflower (Carthamus tinctorius L.) seed in preventing and treating osteroporosis recently. Although numerous studies were done on effects of safflower oil, no attention was given to the role of dietary fiber of safflower seeds. This study was aimed at investigating physiological significance of defatted safflower seed as a source of dietary fiber. Sprague Dawley female rats were assigned one of 5 groups: ovariectomized control (Ovx-control) group and ovariectomized rats 15% (Ovx-ss15) and 30% defatted safflower seed (Ovx-SS30), sham-operated (Sham) group and a normal group. Cholesterol was supplemented to all diets at 0.5% except the normal diet. Ovariectomized rats were pair-fed isocalorically to the Sham group. Ovariectomy caused heavier body weight, but feeding 30% safflower seed brought back to the level of Sham group. Activities of disaccharidases of jejunal mucosa were significantly lowered in Ovx-control group compared to those of Sham, and supplementation of safflower seed tended to increase the activities. Fecal weight of Ovx-SS15 and Ovx-SS30 were almost twice as those of Ovx-control Sham. Propionic acid and butyric acid concentrations per g of feces of Ovx-SS15 and daily excretion of these fatty acids were significantly increased as compared to those of Sham and Ovx-control. In concentration defatted safflower seed supplementation significantly increased fecal bulk and short chain fatty acid production in large intestine of rats.

This study was designed to observe the effects of the feeding Platycodon grandiflorum, Codonopsis Ianceolata, perilla oil and safflower oil on the fatty acid composition in serum and liver of dietary hypercholesterolemic rats. Experimental groups mixed with 5% cellulose +10% lard (group 1, control group), 2% cholestyraemine +10% lard (group 2), 5% C. ianceolata+ 10% perilla oil (group 3), 5% P. grandiflorum+10% perilla oil (group 4), 5% C. ianceolata+10% safflower oil (group 5) and 5% P. grandiflorum+10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. In the fatty arid compositions of serum total fatty arid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was most in the PUFA and it was major fatty acid. Particularly, the other components except the phospholipid fraction in serum lipids were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid content was remarkably more in the groups 5 and 6. In the fatty arid compositions of liver total fatty acid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was more in the PUFA and so it was major fatty acid. Particularly, the arachidonic and eicosapentaenoic acid contents of phospholipid fraction in liver lipids were rather more. from the above research, fatty arid composition of serum and liver lipid components were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid takes up the highest percentage.

This study was designed to observe the effects of feeding the mixed oils of the sardine oil containing n-3 EPA, DHA and the safflower oil which is rich in n-6 linoleic acid on the improvement of the lipids and enzyme activities of serum in rats. Experimental oils mixed with 16% butter (control group) and 8% butter + 8% olive oil, 8% butter and various level of sardine and safflower oils were administered to the male rats of the Sprague Dawley for 4 weeks. The activities of aspartate aminotransferase (AST, EC 2.6.1.1), alanine aminotransferase (ALT, EC 2.6.1.2), lactate dehydrogenase (LDH, EC 1.1.1.27) and alkaline phosphatase (ALP, EC 3.1.3.1) in serum were significantly decreased in the all experimental groups than in the control groups, and activities of ALT and LDH were remarkably lower in the group 5 (4% sardine 0il + 4% safflower oil). Concentrations of total cholesterol and HDL-cholesterol in serum were lower in the other groups than in the dontrol groups, and particularly, lowest in the group 5. Concentrations of LDL, LDL-cholesterol, phospholipid and triglyceride in serum were lower in the all experimental groups than in the control group. Concentrations to total cholesterol and cholesteryl ester in serum were lowest in the group 5. The ratio of cholesteryl ester to total cholesterol was remarkably high in the control group, while group 2 (8% olive oil) was the lowest. From this results, the feeding equal quantity mixed oil with n-3 PUFA rich sardine oil and n-6 PUFA rich safflower oil were effective on the improvement of the lipid composition in the serum. It might be due to the effects of appropriate ratios of P/S, 0.85 and n-6/n-3P, 2.85 in the test lipids.

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.

This study was designed to observe the efforts of the feeding Platycodon grandiflorum, Codonopsis ianceolata, perilla oil and safflower oil on the improvement of the lipids in the serum and liver of dietary hypercholes-terolemic rats. Experimental groups mixed with 5% cellulose+10% lard (group 1, control group), 2% cholestyramine+10% lard (group 2), 5% C. Ianceolata+10% perilla oil (group3). 5% P. grandiflorum+10% perilla oil(group 4), 5% C. ianceolata+10% safflower oil(group 5) and 5% P. grandiflorum+10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. Concentrations of total cholesterol in serum were significantly lower in the all experimental groups (2~6 groups) than in the control group, and particularly, the lowest in the group 2 and 6. Concentrations of HDL-cholesterol in serum were remarkably higher in the groups 2 and 4. The ratio of HDL-cholesterol to total cholesterol was the highest in the group 2. Atherosclerotic index was lower in the groups 2, 4 and 6. Concentrations of LDL, phospholipid and triglyceride in serum were remarkably lower in the all experimental groups than in the control group, and particularly, lower in the groups 2, 4 and 6. Concentrations of free cholesterol and cholesteryl ester in serum were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in the group 2. Concentrations of glucose in blood were the lowest in the group 2. And groups 3 and 5 were slgnificantly lower. Contents of total cholesterol and triglyceride in liver were significantly lower in the all experimental groups than in the control group, and particularlyr the lowest in the groups 2 and 3. Phospholipid content was showed little differenre among groups but the lowest in the group 2. From the above research, the feeding 5% Platycodon grandiflorum+10% perilla oil and 5% Platycodon grandiflorum+10% safflower oil were effective on the improvement of the lipid compositions in serum and liver.
