Safflower is called as the 'beneficial flower' because 'it helps human health', and it was introduced as red flower in Tonguibogam due to the red color of floral leaf. From old times, it has been used for the material of cloth and rouge. Recently, polyphenol compound, the main ingredient of safflower, known as anti-aging and anti-oxidizing material in the healthy food industry becomes the emerging hot topic. This study aims to confirm by DDT (Disk Diffusion Test) assay, MTT assay, and NF-${\kappa}$B Luciferase activity inhibition assay in vitro that polyphenol compound, which is the main ingredient of safflower, has the anti-microbial efficacy to inhibit the growth of acne germs that make troubles for the teenagers or middle aged. Also it aims to evaluate its clinical efficacy on the acne skin, utilizing the facial cleansing cosmetic form of soap sample. This study can contribute to take a major step forward to the development of cosmetic soap for acne in the cosmeceutical industry.

Mt. Jiri located in the southwestern part of Korea is a treasure trove of wild medicinal plants. More than 1200 species currently classified as herbs are grown or cultivated in the area. Recently, safflower has attracted interest because of its ability to control fine wrinkle formation on the neck. The objective of this study therefore was to determine whether the active ingredient of safflower could be used in the form of an extract to reduce wrinkle formation in individuals aged 30 to 59 years. In particular, this study was aimed at determining the extract’s elastase activity and anti-oxidant effect by using DPPH assay in vitro and evaluating the anti-wrinkle efficacy of different types of safflower extracts in improving fine wrinkles on the neck. This study will provide a basis for future studies to develop safflower extracts using advanced composition technology and contribute to the development of the herbal cosmetics industry.

Mt. Jiri, where is located in southwestern area of Korea, can be a treasury of herbal medicine plants grown wild. More than 1200 species currently classified as herbs are grown or cultivated. Recently, the studies on the safflower which attracts the interests in the inhibition of skin aging in the modern people have been actively investigated, and this study aims to confirm that polyphenol compound, the main ingredient of safflower, can be a natural material to cause the delayed effect on the skin aging, inhibiting the generation of wrinkle in the 30 to 40s middle aged females. Primarily, this study is to confirm the anti-oxidizing effect by DPPH assay in vitro, and to evaluate the efficacy of inhibition or improvement on the wrinkle generation in the face skin by clinical trials, additionally. In addition, we are confident to contribute on the improvement of functional cosmetic industry, developing the sample product of anti-aging mask pack which has the main ingredient with the extract of safflower.

This study was conducted to examine the effect of polyphenols from safflower seed on HMG-CoA reductase (HMGR) activity, LDL oxidation and Apo A1 secretion from Hep3B cell. The safflower seed polyphenols were matairesinol (Iignan), enterolactone (lignan metabolite), acacetin (flavone) and serotonin derivative. In addition to safflower polyphenols, mevastatin, ${\alpha}-estradiol,\;{\alpha}-tocopherol$ and soy genistein were tested as reference compounds depending on the type of the test. HMGR source was liver microsome obtained from rat fed 2% cholestyramine for 10 days. Inhibition of HMGR activity was greater with mevastatin (53%) than safflower serotonin derivatives (45%), followed by genistein (35%), but was very small with matairesinol, enterolactone and acacetin. LDL oxidation induced by $CuSO_4$ was suppressed by all the test material used in the present study and in the order of safflower serotonin derivatives> matairesinol > ${\beta}-estradiol$ > genistein > acacetin > enterolactone. Apo A1 secretion from Hep3B cell was significantly stimulated by mevastatin, but moderately (p<0.1) by ${\beta}-estradiol$ and genistein as well as enterolactone. These results suggest that the safflower polyphenols improve body lipid status via inhibition of cholesterol synthesis and suppression of LDL oxidation.

In order to select potential plant resources as functional materials and natural antioxidants, we evaluated antioxidant activity and serotonin derivatives of safflower germplasm collected from five countries. N-(p-Coumaroyl) serotonin (CS) and N-feruloylserotonin (FS) were analyzed by using Ultra Performance Liquid Chromatography (UPLC). Total polyphenol content (TPC) was determined by Folin-Ciocalteu method and antioxidant activities were estimated by 2,2-diphenyl-1-picryl-hydrazil (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS), Ferric reducing antioxidant power (FRAP) and Reducing power (RP) assays. The TPC showed a range of 28.25 to $90.53{\mu}g$ gallic acid equivalent (GAE)/mg dried extract (DE). DPPH, ABTS, FRAP and RP assay were in the range of 18.76 to 93.98, 48.91 to 163.73, 3.80 to 132.29 and 26.32 to $80.08{\mu}g$ ascorbic acid equivalent (ASCE)/mg DE, respectively. Among the five countries, safflower seed collected from Iran had the highest levels of serotonin derivatives and antioxidant activities than other countries (p<0.05). CS showed high correlation with TPC, ABTS and DPPH (r=0.673,0.727,0.820), and FS showed high correlation with DPPH (r=0.740). Accessions IT321214 and IT321215 could be useful for development of new functional materials and could be used as a source of valuable natural antioxidant materials.
