Carthamus tinctorius L. (known as safflower) is a valuable oil plant whose importance is increasing rapidly in the world due to its high adaptation to arid regions. The seeds of this unique plant are especially used in edible oil, soap, paint, varnish and lacquer production. Its flowers are used in vegetable dye production and medicinal purposes beside its features as a coloring and flavoring in food. After the oil is removed, the remaining pulp and plant parts are used as animal feed, and dry straw residues are used as fuel. Beside all these features, its usage as a herbal medicinal plants for various diseases has gained importance on recent years. In this study, it was designed a plant metabolomic approach which transfers all the recent data processing strategies of untargeted metabolomics in clinical applications to the present study. Q-TOF LC/MS-based analysis of the extracts (70% ethanol, hexane, and chloroform) for both seed and flowers was performed using a C18 column (Agilent Zorbax 1.8 µM, 100 × 2.1 mm). Differences were observed in seed and fruit extracts and these differences were visualized using principal component analysis (PCA) plots. The total number and intersections of the peaks in the extracts were visualized using peak count comparison graph. Based on the experimental results, the number of the detected peaks for seeds was higher than the ones for the flowers for all solvent systems to extract the samples.

In this study, we evaluated the fatty acid composition and physiological activities of oils extracted from eight types of seeds, pepper (Capsicum annuum L.), green tea (Camellia sinensis L.), perilla (Perilla frutescens var. japonica Hara), peanut (Arachis hypogaea L.), cotton (Gossypium indicum LAM.), sesame (Sesamum indicum L.), walnut (Juglans regia L.), and safflower (Carthamus tinctorius L.). The composition and quality analysis showed that the oils were potentially suitable for foo-grade applications. The composition analysis showed that the oils were mostly composed of unsaturated fatty acids including linoleic acid and oleic acid. In 3T3-L1 adipocytes, green pepper, perilla, and peanut seed oils inhibited lipid accumulation, and green pepper, perilla, peanut, sesame, walnut, and safflower seed oils induced leptin secretion. These results show that the inhibitory effect of edible seed oils on lipid accumulation, and induction of leptin secretion may be useful for obesity management.

Emulsion-type sausages were manufactured to investigate the effects of CLA-vegetable oils and CLA-lard on quality characteristics of emulsion-type sausage. Each treatments replaced pork back fat with CLA-corn oil (CLA-CO), CLA-safflower seed oil (CLA-SSO) and CLA-lard (CLA-LD) were stored during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The changes in physico-chemical properties, texture, thiobarbituric acid reactive substances (TBARS), fatty acid composition and CLA content of each treatments were measured during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. During storage, pH of control showed higher pH value than that of CLA-vegetable and CLA-lard treatments. The pH values of all treatments was significantly low at storage 14 days (p<0.05). The color L* and a*-value of all the treatments was not significantly changed with the storage periods. Color b*-value of CLA-treatments was higher than that of control during the storage period. Fatty acids composition was changed by addition of CLA-vegetable oils and CLA-lard. All kinds of fatty acids composition were decreased with CLA replacements than that of the control. Whereas linolenic acid content extremely increased by replacement of CLA-vegetable. CLA content of CLA-treatments was extremely increased than that of the control. The cohesiveness, springness, gumminess and brittleness of CLA-LD treatment was significantly higher (P<0.05) than that of the other treatments. The TBARS value of all treatments were significantly increased (P<0.05) as the storage period was passed. TBARS of sausage products containing CLA-CO was the lowest. Summing up the a forementioned results, emulsion-type sausage manufacturing with CLA-vegetable oil and CLA-lard was not affected in physico-chemical properties and texture characteristics. Also, it may be assumed that the high quality sausage can be manufactured with the extent of storage period and CLA accumulation.

N-feruloylserotonin (FS) and N-(pcoumaroyl) serotonin (CS), serotonin derivatives, which have been isolated as major and unique phenolics of safflower seed extract (SSE), are member of hydroxycinnamic acid amides and are implicated in the defense against pathogen infection and insect feeding. In this study, we evaluate inhibitory effects of N-(p-Coumaroyl)serotonin and N-Feruloylserotonin on adipogenesis using oil-red O staining, triglyceride and GPDH activity. we found that while serotonin itself did not suppress differentiation of preadipocytes into adipocytes, N-(p-Coumaroyl)serotonin and N-Feruloylserotonin inhibited the differentiation of preadipocytes into adipocytes in a concentration-dependent manner. In addition, they showed antioxidant effects in DPPH assay. Taken together, these results show that N-feruloylserotonin (FS) and N-(pcoumaroyl) serotonin (CS) suppress differentiation of preadipocytes, suggesting the possibility that these serotonin derivatives can be utilized as an anti-obesity agent.

Emulsion-type sausages were manufactured to investigate the effects of CLA-vegetable oils and CLA-lard on quality of emulsion-type sausage. Each treatments replaced pork back fat with CLA-sesame oil (CLA-SO), CLA-lard (CLA-LD) and CLA-safflower seed oil (CLA-SSO) were stored during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The changes in physico-chemical properties, thiobarbituric acid reactive substances(TBARS) and fatty acid composition of each treatments were measured during 1, 7, 14, 21 and 28 days at 4$^{\circ}C$. The pH values of all treatments significantly(p<0.05) decreased as storage time increased. Sausage products containing CLA-vegetable oils showed higher pH value than that of CLA-lard among the treatments. Color a*-value of CLA-SSO was higher than that of other treatments. During storage, TBARS values of treatments were significantly (p<0.05) increased, sausage products containing CLA-vegetable oils showed lower (p<0.05) TBARS value than CLA-lard, and TBARS of sausage products containing CLA-SSO was the lowest. This result indicated that CLA concentration in emulsion-type sausage did affect the lipid oxidation stability. Fatty acids composition was changed by addition of CLA-vegetable oils and CLA-lard. All kinds of fatty acids content decreased whereas CLA content extremely increased by replacement of CLA-vegetable oils and CLA-lard. The level of CLA content in CLA-vegetable oils was higher than CLA-lard. It may be concluded that emulsion-type sausage could be manufactured using CLA-vegetable oils as a pork fat substitutor without any negative effects on general components or physico-chemical properties.

Powdery and downy mildews caused by Sphaerotheca fusca and Pseudoperonospora cubensis are the most common and serious diseases of cucumber worldwide. In spite of the introduction of highly effective systemic fungicides, control of these diseases remains elusive. Hence, this study aimed to develop an alternative method to chemicals in controlling the diseases by using different types of cooking oil. Egg yolk, which contains a natural emulsifier, lecithin, was selected as a surfactant to emulsify the oils. Among the different cooking oils used, soybean, canola (rape seed), safflower, sunflower, olive, and corn oils showed over 95% control values against powdery mildew of cucumber in a greenhouse test. In particular, 0.3% canola oil emulsified with 0.08% yolk (1 yolk and 60 ml canola in 20 l spray) was found to be the most effective. The treatment resulted in 98.9% and 96.3% control efficacies on powdery and downy mildews, respectively, of cucumber in the field. Canola oil exhibited direct and systemic effect, wherein powdery mildew of cucumber was suppressed only on treated leaves but not on non-treated leaves in a plant, while mycelia and conidia of the pathogen were severely distorted or destroyed by the treatment. The prospect of using the canola oil and yolk mixture as a natural fungicide is highly promising because of its effectiveness, availability, low cost, simple preparation, and safety to humans and the environment. The use of the canola oil and yolk mixture is expected to be an effective fungicide for use in organic farming and home gardening.

A total of 250 laying hens were fed a diet containing 0, 1, 2.5 or 5% conjugated linoleic acid (CLA), and 5% Safflower seed oil (SSO) for 5 weeks, and eggs were collected by week to analyse lipid characteristics of egg yolk. Egg yolk from CLA-fed groups showed significant increase in CLA content with increased CLA in the diet. Dietary CLA also increased the ratio of saturated fatty acids and decreased unsaturated fatty acids in the egg yolk. The proportion of myristic, palmitic, stearic and CLA were increased, while those of oleic, linoleic, linolenic and arachidonic acid were decreased. The cholesterol content in egg yolk was significantly decreased by dietary CLA for 5 weeks feeding. After 7 days of feeding, 5% CLA-fed group showed the lowest cholesterol content in egg yolk. CLAfed groups showed significantly lower 2-thiobarbituric acid-reactive substances (TBARS) values compared to control and SSO-fed group after 14 days of storage. No significant differences in TBARS values among CLA-fed groups were observed at the 28 days of storage. Results suggested that lipid oxidation of egg yolk during cold storage could be inhibited by dietary CLA due not only to changes in fatty acid composition but also to the high concentration of CLA in egg yolk.

The effects of conjugated linoleic acid (CLA) in egg yolk on fatty acid composition and lipid oxidation during chilled storage (4$^{\circ}C$) were investigated. CLA was synthesized according to the method of alkali isomerization using safflower seed oil (SSO). A total of 250 hens (200 days of age) were fed control diet (commercial formula feed for han) or CLA-supplemented diet (1%, 2.5% and 5% CLA) or 5% SSO supplemented diet for 6 weeks, and eggs were collected for analysis of CLA, fatty acid compositons and lipid oxidation. Eggs from CLA-supplemented diets groups showed significantly (p＜0.05) higher CLA content compared to those of control group. The contents of linoleic, palmitic, and myristic acid were increased as well as CLA content by feeding a CLA-supplemented diet. However, the contents of oleic and arachidonic acids in egg yolks were decreased by dietary CLA supplementation. The pH of egg yolk increased by the levels of CLA during storage. The contents of CLA were not significantly (p＜0.05) changed during chilled storage for 28 days, whereas TBARS were significantly (p＜0.05) increased. It is suggested that lipid oxidation of egg yolk might be affected by the levels of CLA in egg yolk due to changes in fatty acid compositions.
