복분자즙을 밀가루에 0%, 5%, 10%, 15%, 20% 첨가하여 제조한 반죽의 리올로지와 식빵의 품질 특성을 조사하였다. RVA상의 최고 점도 및 최종 점도는 대조구에 비해 복분자즙의 첨가량이 증가함에 따라 증가하였다. 파리노그래프상의 수분 흡수율 및 반죽의 저항도는 복분자즙 첨가량이 증가함에 따라 증가하였으나 반죽의 형성시간과 안정성은 반대로 복분자즙의 첨가량에 따라 감소하는 경향을 나타내었다. 복분자즙을 첨가하여 제조한 식빵의 텍스쳐를 측정한 결과 경도, 검성,씹힘성 등은 복분자즙의 첨가량이 증가할수록 유의적으로 증가하였으나 응집성은 유의적인 큰차이를 보이지 않았다. 복분자즙을 첨가하여 제조한 식빵의 관능검사 결과 20% 첨가구가 모든 항목에서 가장 양호한 것으로 나타났다.

In an attempt to find natural sources of antioxidants and whitening agents, comparisons of the antioxidative and tyrosinase inhibitory activities of various ethanol extracts of Cuscutae Semen, Rubi Fructus and Paeoniae Radix were carried out. Comparison of the three ethanol extracts revealed that, Paeoniae Radix had the highest electron-donating ability(79.3%),; however, Rubi Fructus had the highest SOD-like ability(31.1%). The xanthine oxidase experiment exhibited a hindrance effect of 74.3% in Cuscutae Semen, 80.4% in Rubi Fructus and 60.8% in Paeoniae Radix. A tyrosinase inhibitory activity assay was conducted to evaluate the whitening effects of the extracts, The tyrosinase inhibitory activity was 20.1% in the Cuscutae Semen, 54.2% in the Rubi Fructus, 56.3% in the Paeoniae Radix. Based on these results, we suggest that the ethanol extracts of Cuscutae Semen, Rubi Fructus and Paeoniae Radix can be used as food and cosmetic ingredients.

Objectives : The purpose of this study was to examine the antioxidant effects of the extract of Rubi Fructus on TM4 Sertoli cells. Methods : The extract was studied for diphenyl-picryl-hydrazyl (DPPH) radical scavenging activity and cell viability assays on Sertoli cells. In addition, hydrogen peroxide-induced oxidative stress on Sertoli cells were examined by MTT assay. The antioxidant enzyme of Cu/Zn SOD, Mn SOD, catalase protein expression on Sertoli cells were also measured. Results : The results showed that the extract scavenged DPPH radical dose-dependent manner. The extract showed no cytotoxicity at concentration of 1, 5, 10, 50, $100{\mu}g/ml$. The hydrogen peroxide-induced cytotoxicity of Sertoli cells was protected to 88.3% by the extract at concentration of $100{\mu}g/ml$. Cu/Zn SOD and Mn SOD protein expression were significantly increased on Sertoli cells, but catalase protein expression was not significantly changed. Conclusions : In conclusion, the extract of Rubi Fructus has antioxidant effects on Sertoli cells and protect male reproductive system against oxidative stress.

복분자의 포제에 있어 건조방법이 추출특성에 미치는 영향을 규명하기 위하여 생복분자 딸기를 5분간 증자하고, 자연 양건, 적외선 건조 또는 동결건조한 다음 20 mesh 크기로 분쇄하고, 열수나 40% 에탄올(80$^circC$)로 3시간 추출한 후 추출액의 이화학적 특성 및 항산화성을 조사하였다. 가용성 고형분과 총당의 추출수율은 동결건조품에서 가장 높았고 다음으로 적외선 건조품, 양건품 순이었으며, 건조법에 무관하게 에탄올보다는 물 추출액에서 높게 나타났다. 유기산의 추출수율과 추출액의 pH는 물 추출에서는 건조방법별 차이가 없었으나 에탄올 추출에서는 동결건조품에서 다소 높고 낮은 경향을 보였다. 총페놀의 추출수율과 추출액의 유리기 소거능은 동결 건조품, 적외선 건조품, 양건품 순이었으며, 물보다 에탄올 추출에서 높게 나타났다. 동결건조품에서 L값은 가장 높았고 a와 b값은 가장 낮았으며, 물보다 에탄올 추출에서 L과 b값은 높았으나 a값은 낮게 나타났다. 이로써 복분자 포제에 있어 전통적 자연 양건보다는 적외선 및 동결건조 특히, 동결건조의 적용에 의해 품질향상이 가능하며, 또한 총가용성 성분의 추출에는 물 추출이, 항산화성 성분의 추출에는 에탄올 추출이 유리한 것으로 확인되었다.

Objectives: Rubi Fructus(fruit of Rubus coreanus Miq.) composed of Polygonum multiflorum THUNB. and some medical herbs is known as formula of senescence delay effect. The purpose of this study is to investigate the effect of Rubi Fructus(fruit of Rubus coreanus Miq.) on antioxidant enzyme activity such as Thiobarbituric acid reactive substance(TBARS), Superoxide dismutase(SOD), Catalase(CAT), Glutathione peroxidase(GSH-px) in rat erythrocytes and blood plasma. Methods: Sprague-Dawley rats were divided into 3 groups, Normal group(supplied enough water and feeds only, Normal Group), D-galatose administered group(injected D-galatose 50mg/kg, 1time/day for 6 weeks, Control Group) and Rubi Fructus (fruit of Rubus coreanus Miq.) administered group(D-galactose 50mg/kg and Rubi Fructus(fruit of Rubus coreanus Miq.) extracts 85.0mg/200g 1time/day for 6 weeks, BBJ Group). Rats were sacrificed and TBARS, SOD, CAT, GSH-px, Plasma total lipid, Plasma triglyceride and cholesterol were measured in rat erythrocytes and blood plasma. Results : Plasma TBARS concentrations of all experimental group were not significantly different. Red blood cell(RBC) SOD activities of BBJ group was increased, and RBC catalase activities of all experimental group were not significantly different. RBC GSH-px activities of BBJ group was increased. Plasma total lipid concentration of BBJ group were significantly lower than those of control. Plasma triglyceride, total cholesterol and HDL-cholesterol concentrations of all experimental group were not signi ficantly different. Conclusions: According to the above results, it is considered that Rubi Fructus(fruit of Rubus coreanus Miq.) is effective in inhibiting lipid peroxidation and increasing antioxidative enzyme activities in D-galactose induced aging rat.

Rubi Fructus (fruit of Rubus coreanus Miq.), oriental medicine, has been used for remedy of the liver diseases and for tonic. In order to investigate the oxygen free radical, a harmful factor of aging, in liver of rats fed diets supplemented with the Rubi Fructus water extract(RX), Sprague-Dawley male rats have been fed a diet supplemented with 3% or 5% RX for a month. In rats fed 3% RX supplemented diet, hepatic cytochrome P-450 contents appeared to be increased, and catalase and superoxide dismutase activities were significantly increased compared with the control. There was no difference in glutathione peroxide and glutathione-S-transferase activities between the rats fed RX supplemented diets and the control diet. In conclusion, it is likely that rats fed a diet supplemented with RX may have the oxygen free radicals detoxication potential.

To prevent and treat the osteoporotic fracture, more attention should be paid in old age patients. Osteoclast which has ability to bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Rubi Fructus has been widely used in Oriental medicine. Extracts of the leaves and fruit of Rubus species have been used in various countries as natural remedies to treat diabetes, infections, colic, and burns. However, the effect of extract of Rubi Fructus (fruit of Rubus coreanus Miq.) in osteoclast differentiation remains unknown. Thus, we evaluated the effect of Rubi Fructus on receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclast differentiation. Here we found that Rubi Fructus significantly inhibited osteoclast differentiation induced by RANKL. Rubi Fructus suppressed the activation of p38 pathway and NFkB in bone marrow macrophages (BMMs) treated with RANKL. Also, Rubi Fructus significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Rubi Fructus greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. Taken together, our results demonstrated that Rubi Fructus may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.

Obesity is one of causes of the all adult diseases. We investigated the body weight decrease effect of the selected plants by digestive enzyme activity inhibition test. In a preliminary test, Inonotus obliquus and Rubus coreanus Miq. were found to be effective. Based on this result & previous result, we manufactured the mixture of plant extracts named as Misol$^{TM}$. Misol is applied anti-obesity beverage and rice. When we administered Miso/ sub TM/ to rats, it was found to be effective in body weight decrease. Result that is experimented during 20 weeks, is effective body weight and total cholesterol, triglyceride decrease. In case of human, anti-obesity beverage administered group showed 5.65% body weight decrease, 4% waist length decrease and 6% abdomen length decrease respectively. And anti-obesity rice administered group showed 2.3 kg body weight decrease, 2.9 cm waist length decrease and 3.74 cm abdomen length decrease respectively. This body control effect was supported by plant extracts in the Misol, anti-obesity beverage and rice - administered group. From these results, we suggest that this functional food could be helpful for body weight controlling obesity.
