홍화씨는 한방 및 민간에서 뼈에 우수한 작용이 있는 것으로 알려져 오랫동안 복용되어 왔다. 최근 고령화 사회를 맞이하면서 골다공증 문제는 사회적인 문제로 인식되고 있으며 저자들이 기존에 실시한 실험결과에 의하면 홍화씨 분말은 난소를 적출한 rat에서 골다공증의 예방효과를 나타내었다. 그러나 아직까지 골다공증이 유발된 rat에서 홍화씨 분말이 미치는 효과에 관한 실험적 자료가 제시된 것은 별로 없다. 이에 저자들은 홍화씨 분말이 골다공증의 치료에 미치는 효과를 알아보기 위하여 본 실험을 실시하였다. 실험동물은 체중 230 g의 12주령의 Sprague-Dawley Rats를 사용하였으며, 양쪽 난소제거 후 7주부터 홍화씨 분말을 매일 0.3 g씩 복용시키면서 1, 3 및 5주 후에 경골을 채취하여 관찰하였다. 채취된 조직은 통상적인 주사전자현미경 시료제작법으로 고겅과정을 거친 후 10% 질산으로 12시간 탈회하여 뼈의 단면을 노출시키고 탈수, 건조 및 금도금 과정을 거쳐 주사전자현미경(Hitachi, S-450)으로 관찰하여 촬영하였다. 관찰결과 대조군은 골수강에서 피질골까지의 두께의 감소와 골수강의 확장이 심하였으나, 홍화씨 분말을 투여한 실험군에서는 1주에서 5주까지 거의 같은 소견을 나타내었다. 이상의 결과를 종합해보면 홍화씨 분말은 여성호르몬 결핍으로 인한 골다공증의 치료에 효과가 있는 것으로 사료된다.

Objectives This study investigated the effect of purified safflower (Carthamus tinctorius Linne) and safflower seed (Carthamus tinctorius L. seed; CS) extract, using hot water and ethanol extract methods , on the osteogenic differentiation of MC3T3E1 cells.Methods The safflower and safflower seed were extracted with hot water and ethanol. The samples were concentrated by a rotary evaporator and then freeze-dried using a freeze-dryer. The MC3T3E1 cells were propagated and maintained in DMEM (Gibco) containing 10% FBS and a 1% antibiotic antimycotic solution. To induce osteogenic differentiation, the cells were treated for 14 days with DMEM with 10 mM β-glycerophosphate and 50 μM ascorbic acid. Extract doses were confirmed by the results of an MTT assay, and treatment of the extracts was performed in a differentiation medium every two days. The ALP staining and activity were tested after osteogenic differentiation for five days, and after 14 days, osteogenic differentiation was determined by alizarin red S staining. The mRNA expressions of osteogenic-related genes were quantified using quantitative real-time PCR.Results In the results of the MTT assay, all concentrations of safflower extracts had no toxicity in the MC3T3El cells. But in the groups of 100 ng/ml and 200 ng/ml concentrations of safflower seed extracts, the cell viability was significantly reduced by up to 40-50%. So we fixed the treatment concentration of the extract at 50 ng/ml. In the ALP and alizarin red S staining, all extract groups increased osteogenic differentiation compared with the control group. The water-safflower extract group showed the highest mRNA level of Alp, Runx2, and Dlx5 genes. The mRNA level of Ocn, an osteogenic gene related to late-stage differentiation, in the ethanol-safflower extract group increased the mineralization more significantly than in other groups.Conclusions These data suggest that the extract of safflower increases the osteoblastic differentiation activates of MC3T3E1 cells like the extract of safflower seed. The water-extract and ethanol-extract of safflower have effects on different stages of osteogenesis in MC3T3El. Not only safflower seed but also safflower will be useful therapeutic reagents for age-associated chronic diseases such as osteoporosis.

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.

In this study, the twenty-four ethyl acetate extracts of twenty-two medicinal plants, traditionally used in Vietnam as anti-diabetes agents, were investigated for ${\alpha}$-amylase and protein tyrosine phosphatase 1B (PTP1B) enzymes inhibitory activity in vitro. The results indicated that, twelve materials (50.0%) showed moderate to strong inhibitory activity in ${\alpha}$-amylase inhibitory activity with $IC_{50}$ values ranging from 2.5 to $48.8{\mu}g/mL$; meanwhile, ten extracts (41.6%) could demonstrate PTP1B activity with $IC_{50}$ values less than $30.5{\mu}g/mL$. Some plants presented interesting activities against both of ${\alpha}$-amylase and PTP1B enzymes such as Catharanthus roseus, Carthamus tinctorius, Momordica charantia, Gynostemma pentaphyllum, Glycyrrhiza glabra, Smilax glabra, Psidium guajava (leave), and Rehmannia glutinosa. The study may provide a proof, at least in a part, for the ethno-medical use in diabetes disease of these plants.

We investigated whether ethanol extracts of the safflower seeds containing phenolic compounds were responsible for the bone-protecting effects. Crude ethanol extract (CEE) of the safflower seeds was fed for 4 weeks at the level of 1% in diet to female Sprague-Dawley rats that had been subjected to bilateral ovariectomy (OVX). The CEE effects (OVX+CEE) were evaluated by comparing results obtained from OVX, Sham, and OVX injected with $17{\beta}$-estradiol ($OVX+E_2$) groups. OVX resulted in a dramatic reduction in the trabecular bone mass of the proximal tibia (approximately 40% of the Sham group) and an increase in fat deposition in bone marrow. In $OVX+E_2$ group, the bone loss was completely prevented as well as marrow adiposity. In OVX+CEE group, approximately 80% of the bone mass was maintained compared with Sham group and fat deposition in the bone marrow was prevented. Meanwhile, the partially purified ethanol extract containing the phenolic compounds stimulated proliferation of the ROS 17/2.8 osteoblast-like cells in a dose-dependent manner, as potently as positive controls of $E_2$ and genistein. The present data demonstrate that the ethanol extracts of safflower seeds reduced bone loss caused by estrogen deficiency. The bone-protecting effect of safflower seeds seems to be mediated, at least partly, by the stimulating effect of the phenolic compounds on the growth of osteoblasts.

Background: To obtain useful safflower resources for breeding and research of functional materials, the present study was conducted to determine fatty acid compositions and antioxidant activities of 281 safflower accessions collected from East Asia including South Korea. Methods and Results: Lipid contents and fatty acids compositions were evaluated using soxhlet extraction and gas chromatography, respectively. A antioxidant activities were analyzed using a spectrophotometer. The evaluation range of safflower accessions showed very wide variation. In terms of lipid contents, the China accessions were higher than the collection from other regions, whereas antioxidant activities did not differ among regions. The result of the principal component analysis showed that the first and second principal component cumulatively explained 90.6% of the total variation. In clustering the safflower accessions, the tree showed four major clades. Group II (16 accessions) was high in lipid content, oleic acid and linoleic acid, whereas group III (50 accessions) exhibited higher antioxidant activities than other groups. Conclusions: It was recommended that the China collections be utilized as a useful resource for research on functional oil materials. These results provided valuable information for safflower breeders and researchers of functional food.
