  • The purpose of this study was to increase the ultraviolet-light (UV)-cut ability of cellulose fabrics (cotton, ramie, and rayon) dyed with safflower yellow colorants. For this purpose, samples treated with UV-cut agent and tannic-acid were compared with the untreated samples after UV exposure in terms of K/S value, color changes(${\Delta}E$), SEM, and strength retention. The K/S value rapidly decreased after 28 days exposure, whereas the K/S value of the samples treated with both UV-cut agent and tannic-acid decreased to less than that of the untreated samples. In color changes, $L^*$ increased while $a^*$ and $b^*$ decreased, indicating less red and yellow character in color. This induced a change in the hue, value and chroma values. However the color change(${\Delta}E$) of the samples treated with both UV-cut agent and tannic-acid was less than that of the untreated samples. Scanning electron microscopy (SEM) pictures showed a severe degradation by exposure in all samples. Tensile strength rapidly decreased after 28 days for cotton and rayon, and after 21 days for ramie. However, the strength retention of the samples treated with UV-cut agent and tannic-acid was higher than that of the untreated samples.

  • This study was carried out to find the effect of the pinching and planting density on yield of petal and grain in safflower (Caythamus tinctorius L.). The planting density was high effective branch number per $m^2$ compared with pinching, and effective flower bud was most in $270ea/m^2$ in three line planting density, but in case of pinching was few at $186{\sim}223ea/m^2$ Grain yield was increased with 231 kg/10a at double line planting density compared with in 220 kg/10a of control. Petal yield of double line and three line planting density was 25.4 kg/10a and 26.9 kg/10a, it was increased 15, 22% compared with 22.0 kg/10a of control, respectively.

  • Ultraviolet (UV) is one of the major factors harmful to skin health. Irradiation with ultraviolet accelerates the decline of skin function, causing the skin to have deep wrinkles, dryness, decreased procollagen production, and degradation of collagen. Novel materials are needed to prevent the aging of the skin by blocking the effects of UV. Safflower seed oil (Charthamus tinctorius L., SSO) contains significantly high levels of unsaturated fatty acids and phytochemicals. SSO has been traditionally used in China, Japan, and Korea to improve skin and hair. Our objective in this study was to determine the effect of SSO and its active compound acacetin on UVB-induced skin photoaging in HaCaT cells and human dermal fibroblasts (HDF). SSO inhibited UVB-induced matrix metalloproteinase-1 (MMP-1) at both protein and mRNA levels in HaCaT cells and HDF. MMP-1 is known to play important roles in collagen degradation and wrinkle formation. Acacetin, a type of flavonoid, is present in SSO. Similar to SSO, acacetin also inhibited UVB-induced MMP-1 protein and mRNA levels in HaCaT cells and HDF. MMP-1 mRNA is primarily regulated by the mitogen-activated kinase (MAPK) signaling pathway. Acacetin regulated the phosphorylation of JNK1/2 and c-jun, but did not inhibit the phosphorylation of ERK1/2, p38 and AKT. Taken together, these results indicate that SSO and its active compound acacetin can prevent UVB-induced MMP-1 expression, which leads to skin photoaging, and may therefore have therapeutic potential as an anti-wrinkle agent to improve skin health.

  • 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 investigate the plant growth and seed yield between rain-shelter plastic house and out-door cultivation, and analysed the effect of harvesting time on seed quality. In rain-shelter plastic house cultivation, emergence date was 3 days and flowering date was 8 days earlier than out-door cultivation. Seed yield of rain-shelter plastic house cultivation was increased $25\%$ compared to out-door cultivation and it's more beneficial than out door cultivation. The crude fat content was higher and seed was whiter and better quality in rain-shelter plastic house cultivation than out-door cultivation. In out-door cultivation, the crude fat content was steadily increased until 40 days after full bloom, but the seed color was getting dark which was harvested at 30 days after full bloom and the color was turn to the dark brown when the seed was harvested at 40 days after full bloom. Harvesting of safflower seed's quality is best between 20 days and 30 days after full bloom.

  • This study was to investigate the effects of dietary linoleic acid(18:2\omega6, LA) and aipha-linolenic acid(18:3\omega3. \alpha-LNA) levels on brain development and fatty acid compositions of various lipid classes in the chicken embryo brain tissues. Thirty two ISA Brown layers, 52 weeks-old, were divided into four groups. Birds of each group were given corn-soybean meal based diets added with 1) safflower oil 8%, 2) safflower oil 6% + perilla oil 2%, 3) safflower oil 2% + perilla oil 6%, or 4) perilla oil 8%. Mter 15 days fed the diets. the layers were artificially inseminated to obtain fertile eggs. During the incubation. embryonic brains were sampled at 15th and 21st days. Fatty acid contents were quantitated by using heptadecanoic acid (17:0) as an internal standard. No significant differences in brain weight and in contents of various lipids such as phospholipid. triglyceride, cholesterol. cholesterol ester and free fatty acid in the tissues were found among the dietary groups (P<0.05). The ratios of AA/LA in the brain lipid classes were lowered as the dietary levels of perilla oil were increased. Higher LA was found in phosphatidylcholine(PC) than arachidonic acid (20:4\omega6. AA), meanwhile the level of LA was less than AA in phosphatidylethanolamine(PE). Docosahexaenoic acid(22:6\omega3, DHA) was the* major fatty acid in the tissue and its content in PE was 2.5~3 times higher than in PC. DHA level in the phospholipid reached at a peak (1.7~1.8 mg/brain) in dietary groups added with 6% or 8% perilla oil. suggesting that no more increase in that fatty acid level in the brain tissue could be obtained by consuming more \alpha-LNA, the major precursor of DHA.

  • 'Jinsun', a new variety of safflower(Carthamus tinctoris L.), was developed by Kyonggi-do Agricultural Research and Extension Services in 2000. It was bred with pure line selection from Namwon local variety population. Jinsun is relatively resistant to Gleosporium carthami and has more flower head and higher ripened grain ratio. Its flowering date was June 22 in Hwaseong, Gyeonggido and contains more protein and linoleic acid relatively in grain compared with Cheongsu, check variety. Grain yield of Jinsun was 11% higher than Cheongsu.
