The ultimate goal of periodontal therapy is the regeneration of periodontal tissue and the repair of function. For more than a decade there have been many efforts to develop materials and methods of treatment to promote periodontal tissue regeneration. Recently many efforts are concentrated on the regeneration potential of material used in traditional medicine. Safflower(Carthamus tinctorius L.) seed extract(SSE) have long clinically used in Korea to promote bone formation and prevent osteoporosis. The purpose of this study was to examine the effects of SSE on bone formation in human osteoblastic cell line. Human fetal osteoblastic cell line(hFOB 1.19) was cultured with DMEM and SSE($1{\mu}g/ml$, $10{\mu}g/ml$, $100{\mu}g/ml$, $1mg/ml$) at $34^{\cdot}C$ with 5% $CO_2$ in 100% humidity. The proliferation, differentiation of the cell was evaluated by several experiments. Cell proliferation was significantly increased at $10{\mu}g/ml$, $100{\mu}g/ml$, 1mg/ml of SSE after 3 and 7 days incubation(p<0.05). Cell spreading assay was significantly increased at $100{\mu}g/ml$ of SSE after 3 days and $1{\mu}g/ml$, $10{\mu}g/ml$, $100{\mu}g/ml$, 1mg/ml of SSE after 7 days(p<0.05). Alkaline Phosphatase(ALP) level was significantly increased in $10{\mu}g/ml$, $100{\mu}g/ml$, 1mg/ml of SSE(p<0.05). Collagen synthesis was significantly increased at $10{\mu}g/ml$, $100{\mu}g/ml$, 1mg/ml of SSE(p<0.05). A quantified calcium accumulation was significantly increased at $10{\mu}g/ml$, $100{\mu}g/ml$ of SSE(p<0.05). ALP and osteocalcin mRNA was expressed in $100{\mu}g/ml$ of SSE by RT-PCR. These results indicate that SSE are capable of increasing osteoblasts mineralization and may play an important role in bone formation.

This study was carried out to investigate the effect of safflower seed powder on the physicochemical characteristics of ground pork during refrigerated storage. Three types of ground pork were evaluated: 20% pork fat added (PF, control), 10% pork fat and 10% added safflower seed powder (PFS), and 20% added safflower seed powder (SS). The pH increased during storage, but decreased after 10 days of the storage (p<0.05). The pH was lower in PFS and SS than that in PF after 10 days of storage (p<0.05). The TBARS (2-thiobarbituric acid reactive substances) values increased with longer storage period (p<0.05), and those of PF, PFS and SS were 1.186, 0.686 and 0.577 mg MA/kg, respectively, after 10 days of storage. The $L^*$ values for external color of PF and PFS decreased (p<0.05), but that of SS was not significantly different after a longer storage period. The $a^*$ values decreased (p<0.05), but the $b^*$ values were not significantly different with longer storage period. The $L^*$ values for internal color of PFS and SS decreased (p<0.05), but that of PF was not significantly different with longer storage period. The $a^*$ value of PF decreased (p<0.05), but that of SS increased with longer storage period. The $b^*$ value decreased (p<0.05), but those of PFS and SS were not significantly different with longer storage period. Water holding capacity decreased with longer storage period, and that of SS was the highest (p<0.05). Cooking loss of PFS and SS was not significantly different with longer storage period, and that of PF was the highest (p<0.05). The reduction in diameter of the samples was not significantly different with longer storage period, and that of PF was the highest (p<0.05). Hardness and chewiness of samples increased, but springiness and cohesiveness decreased with longer storage period (p<0.05). Replacing animal fat with safflower seed powder was effective and may be useful as an innovative meat product.

Health drinks were prepared with freeze dried powder of 60% ethanol extract (60% EFDP), 60% ethanol extract after hydrolysis with amyloglucosidase (60% AEFDP) and 80% ethanol extract (80% EFDP) from roasted safflower seed. Quality characteristics and antioxidative properties were investigated. Yield of freeze dried powders were ranged in $4.67%{\sim}5.62%$. Brix, pH and titratable acidity of safflower drinks were ranged in $11.4{\sim}14.2%$, $2.83{\sim}3.34$ and $0.09{\sim}0.91%$, respectively. Content of total phenolic compounds was much more in 80% EFDP (117 mg/g) and safflower drink-I (SD-I, 440 ppm) than others. Content of total flavonoid was observed in higher level in 60% EFDP (49 mg/g) and safflower drink-V (SD-V, 138 ppm) than others. Antioxidant compounds such as N-[2-(5-hydroxy-1H-indol-3-yl)ethyl]ferulamide(serotonin-I) and N-[2-(5-hydroxy-1H-indol-3yl)ethyl]-p-coumaramide(serotonin-II) exhibited higher contents of 21.09 ppm, 33.56 ppm in 60% EFDP and of 3.83 ppm, 5.81 ppm in safflower drink-II (SD-II) than others. Content of acacetin was much more in 80% EFDP (13.53 ppm) and safflower drink-IV (SD-IV, 1.14 ppm) than others. From the DPPH test to measure antioxidant activity, it was shown that 80% EFDP and SD-I have stronger scavenging activities of 94.58% and 94.88%, respectively, while BHA standard solution does 93.88%. Among drinks, SD-II was revealed to have highest level on overall acceptance, color and flavor through sensory evaluation. These results induced that safflower seed can be used as natural antioxidant and functional food material.

This study was conducted to evaluate the growth characteristics, phenolic concentration and antioxidant capacity of safflower (Carthamus tinctorius L.) and amaranth (Amaranthus spp.) sprout and investigate the possibility of using super absorbent polymer (SAP) as a medium in hydroponic cultivation in a plant factory. The control was used a commercial sprout cultivation tool (19 × 14 × 9 cm, W × D × L), and a treatment (SAP) was added on the cultivation tool to compare the effect of SAP. Safflower sprouts were immersed in a distilled water at 30 ℃ for 5 hours, and then grown in a plant growth chamber. The temperature and relative humidity were maintained at 25 ± 1℃ and 70 ± 4%, respectively. The light condition was maintained at 35 ± 6 μmol·m-2·s-1 (12h). Amaranth sprouts were grown in a plant growth chamber maintained with temperature of 25 ± 2℃, relative humidity of 70 ± 5% and light condition of 188 ± 10 μmol·m-2·s-1 (16h). A physical and chemical characteristic of SAP, and a germination rate, growth characteristics and secondary metabolites were analyzed in both safflower and amaranth. There was no significant effect on SAP in a germination rate, growth and secondary metabolites of safflower compared to the control, whereas amaranth grown under SAP was higher in germination rate, dry weight, phenolic concentration, and antioxidant capacity compared to the control. As a result, this study was suggested that cultivation of sprouts using SAP would be possible in a plant factory, and further studies on SAP on plant physiological response are required.

잇꽃(Carthamus tinctorius L.)은 국화과에 속하는 두해살이 초본 식물로 한자명은 홍화(紅花), 영명으로는 Safflower를 사용하고 있다. 잇꽃의 원산지는 이집트, 아프카니스탄 등의 서남아시아가 원산지로 알려져 있으며, 우리나라의 잇꽃 재배면적은 2010년 39 ha 수준이 재배되다가 2016년에는 67 ha로 재배면적이 증가한 것으로 보고되고 있다. 우리나라에서 잇꽃 이용은 잇꽃 종실을 위주로 이용되고 있으나 일본의 경우 잇꽃의 경관적 가치를 활용하여 산형현(山形縣)에서는 홍화축제가 매년 개최되고 있으며, 미국 등에서는 잇꽃의 저온압착유가 기능성 건강식품류로 판매되고 있다. 본 연구는 일조시수가 짧은 표고 500 m의 준고랭지에서 잇꽃의 경관적 가치 활용도를 평가하기 위해 차광조건에 따른 개화특성 및 종실 수량성을 평가하기 위해 수행되었다. 비가림 하우스에서 5월 9일 파종후 생육 54일차인 7월 5일 개화기에 지상부 발육량을 조사한 결과 차괄비율이 강해질수록 엽장폭비가 감소하여 세장형에서 장타원형으로 성장함을 알수 있었고, 분지수는 30% 차광조건에서 증가하는 경향을 보였다. 같은 시기에 조사한 엽면적에서는 30% 차광에서 증가하다가 차광비율이 높아질수록 감소하였으며, 식물체당 총 착화수는 30% 차광조건에서 20.3화/주로 가장 많았고 2차 화경의 착화수도 많은 경향을 보였다. 착생된 꽃의 개화단계를 3등급으로 구분하여 비율을 조사한 결과 차광 조건에서는 개화 2, 3단계의 비율이 무차광에 비해 낮아 개화가 지연됨을 알수 있었고, 건조한 관상화의 색도에서는 차광비율이 높아질수록 b 값이 증가하여 황색값이 높아지는 것을 알수 있었다. 파종 후 생육 94일 차인 8월 13일 종실을 수확하여 식물체당 100립중을 조사한 결과 무차광 4.9 g에 비해 차광조건에서는 감소하는 경향을 보였고, 종실수량성에서도 무차광에서 201.1 kg/10 a로 가장 높아 차광조건에서 잇꽃 재배는 개화지연에 의한 등숙률의 감소로 종실수량성이 감소하는 것으로 판단되었다.

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.
