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.

The objective of this study is to investigate the dyeing properties of safflower yellow dye on silk for the standardization of dyeing process and color reproducibility. Yellow colorants were water-extracted from safflower petals, concentrated, and freeze-dried to obtain colorants powder. The effects of dye concentration, dyeing temperature, and pH of dye bath were studied in terms of dye uptake and shade. Fastness to dry cleaning and light was evaluated. Dye uptake increased with raising temperature and brighter and more vivid yellow shade was obtained when dyed at $30^{\circ}C$. As colorants concentration increased, dye uptake increased progressively and the shade got darker and deeper. Maximum color strength was obtained at pH 3.5. It was speculated that the adsorption of colorants seemed to occur mainly by hydrogen bonding and physical force at pH 5.5 and by ionic bonding as well as hydrogen bonding below isoelectric point(pH 3.8-4.0). The results of reproducibility test showed acceptable color difference in the range of $1.11{\sim}2.01$. Washing fastness was fairly good as 4/5 rating, while light fastness was 2/3 rating.

This research was carried out to clarify the germination characteristics with reference to hard seed coat in safflower. Morphologically, seed coat surface has hilum and micropyle which were evident during seed development stage. In the flower of developing seeds, the hilum area is connected with placenta of maternal tissue while the micropyle area is connected with the style of pistil. When the seeds imbibed, the hilum surface began to crack and the embryo protrudes through the hilum. To investigate the route for moisture absorption and gas exchange on the seed coat, the hilum and the micropyle were artificially sealed by paraffin. The seeds whose hilum were sealed could not germinate, which indicates that the exchange of moisture and oxygen takes place through hilum in safflower seeds. The germination was tested at $15^{\circ}C$, $20^{\circ}C$, and $25^{\circ}C$ by three substrates with different moisture conditions; top of paper method (hilum submerged in water), between-paper method, and soil seeding. The germination percentages were 31.3% at $15^{\circ}C$, 15.7% at $20^{\circ}C$ and 6.0% at $25^{\circ}C$ in the top of paper method; and 45.5% at $15^{\circ}C$, 30.0% at $20^{\circ}C$ and 14.0% at $25^{\circ}C$ in the between-paper method; and 80.0% at $15^{\circ}C$, 77.0% at $20^{\circ}C$ and 78.0% at $25^{\circ}C$ in the soil seeding, respectively. When the internal structure of hilum was investigated through SEM, it was found out consisting of vascular bundle element. In conclusion, the hilum of safflower seed was closely related with water absorption and gas exchange during initial germination process.
