Phytoestrogens derived from plants and foods, which are diphenolic compounds with structural similarities to natural and synthetic estrogens, have been shown to estrogenic and antiestrogenic actions. Particularly, recent study revealed that phenolic compounds in safflower seed, such as serotonin derivatives, lignans and flavonoids, could be acted as phytoestrogens. Safflower (Carthamus tinctorius L.) seed extract (SID C.SE), therefore, are receiving a renewed interest as potential therapeutic source against skin wrinkles induced by estrogen deficiency. This study was conducted to investigate the anti-wrinkle effect of SID C.SE on normal human fibroblasts through the expression of type I procollagen and UVA-induced MMP-1 in vitro. The SID C.SE increased the type I procollagen expression, comparable to trans-retinol and reduced UVA-induced MMP-1 expression in a dose-dependent manner. The clinical study indicated that cream group treated with $0.1\%$ SID C.SE significantly reduced a skin wrinkles, as compared with a control (non-treated cream group) (p<0.05). These results suggest that the safflower seed extract may be useful as potential source of anti-wrinkle cosmetics.

This studies were conducted to provide the basic information on safflower collections and to identify the variations which could be utilized in safflower breeding programs, The RAPDs was used to clarify the genetic relationships among safflower collections and to classify them into distint genetic groups. Among 30 of 10 mer primers in RAPD analysis, twenty were selected as the appropriate primers for identification of the genetic characters in safflower collections. Amplified PCR showed the highly reproducible bands at $3.0{\sim}0.2kb$. The number of bands amplified with the each primer showed the variations ranged from 2 to 11, with the average of 5.6. Total of 111 bands were identified among 20 selected primers used in PCR reaction and 84 bands (75.7%) showed polymorphism. Based on the similarity value of 0.14 in dendrogram derived from the cluster analysis using RAPD-PCR, the 30 safflower collections were classified into 11 groups. The two main groups, VII and VIII included 7 collections (23%) and 8 collections (27%), respectively. Most of the collections in group VII were the Korean collections (85%).

The therapeutic effect of safflower seed powder on experimental osteoporosis in the rat induced by ovariectomy was evaluated. Thirty Sprague-Dawley rats were ovariectomized at the age of 12 weeks. Seven weeks postovariectomy, rats were divided into two groups: control and safflower seed powder treated group. Five animals from each group were sacrificed at the following time points: 1, 3, and 5 weeks. Scanning electron microscopic observation and morphometric analysis of the tibiae epiphysis showed that the administration of safflower seed powder significantly prevented reduction of cortical bone width and bone volume compared with the control group. In conclusion, safflower seed powder contains something that prevent bone loss due to estrogen deficiency, and was effective in preventing the osteoporotic decrease of bone mass.

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.

Eight flavonoids, apigenin-6-C-β-D-glucopyranosy l-8-C-β-D-glucopyranoside (AGG), quercetin 7-O-β-D­glucopyranoside (QG), luteolin 7-O-β-D-glucopyranoside (LG), quercetin 7-O-(6'-O-acetyl)-β-D-glucopyranoside (QAG), luteolin 7-O-(6'-O-acetyl)-β-D-glucopyranoside(LAG), quercetin (Q), luteolin (L) and acacetin 7-O-β­D-glucuronide (AG) were determined by HPLC in the safflower (Carthamus tinctorius L.) leaf during growth and processing. During growth, levels of five flavonoid glycosides (AGG, QG, LG, QAG, & LAG) in the leaf increased progressively at over time according to growth stages, reached a maximum before June 11, and then decreased sharply, while those of three flavonoid aglycones (Q, L, & AG) increased greatly at the early stage of growth, reached a peak before May 28, and then decreased rapidly. During the steaming process, contents of five flavonoid glycosides increased rapidly with increased steaming time, reached a maximum after 5 min of steaming, and then decreased, whereas those of flavonoid aglycones except for AG decreased sharply with increased steaming time. During the roasting process, contents of three flavonoid glycosides decreased rapidly with increased roasting time, whereas those of two acetylflavonoid glycosides (QAG & LAG) and three flavonoid aglycones increased progressively with increased roasting time, reached a maximum after 3 min of roasting, and then decreased. These results suggest that appropriate steamed and roasted safflower leaves are a rich source of flavonoids, and may be a good source of bioactive components as a functional leaf tea.

An in vitro study was conducted to examine the effect of monensin or fish oil addition on bio-hydrogenation of $C_{18^-} unsaturated fatty acids and CLA production by mixed ruminal bacteria when incubated with safflower oil. Commercially manufactured concentrate (1%, w/v) with safflower oil (0.2%, w/v) were added to mixed solution (600 ml) of strained rumen fluid and McDougalls artificial saliva (control). Monensin $Rumensin^{(R)}$, 10 ppm, w/v, MO), mixed fish oil (0.02%, w/v, absorbed to 0.2 g alfalfa hay, FO) or similar amounts of monensin and fish oil (MO+FO) to MO and FO was also added into the control solution. All the culture solutions prepared were incubated in the culture jar anaerobically at $39^{\circ}C$ up to 12 h. Higher pH (p<0.047) and ammonia concentration (p<0.042) were observed from the culture solution containing MO at 12 h incubation than those from the culture solutions of control or FO. The MO supplementation increased (p<0.0001-0.007) propionate proportion of culture solution but reduced butyrate proportion at 6 h (p<0.018) and 12 h (p<0.001) of incubations. Supplementation of MO or MO+FO increased (p<0.001) the proportions of $C_{18:2}$. The MO alone reduced (p<0.022-0.025) the proportion of c9,t11-CLA compared to FO in all incubation times. The FO supplementation increased the proportion of c9,t11-CLA. An additive effect of MO to FO in the production of c9,t11-CLA was observed at 6 h incubation. In vitro supplementation of monensin reduced hydrogenation of $C_{18^-}$UFAs while fish oil supplementation increased the production of CLA.

To clarify the efficient application method of sulfur in safflower, we investigated the growth and seed yield as affected by ammonium sulfate (AS) and sulfur powder. AS was applied to the soil with four levels of 0, 4, 8, and 12 kg/10a and was applied by foliar application with 2 kg/10a as sulfur content compared with sulfur powder 20 kg/10a. By the application of sulfur fertilizer, plant height, stem diameter, and weight of stem and leaves tended to be greater than control. AS was more efficient than sulfur powder in growth of safflower. Sulfur application showed positive effect on yield components and seed yield was increased by $4-10\%$ compared to control. In application effects, AS and foliar application were more efficient than sulfur powder and soil application, respectively.
