In this study we manufactured mulberry fruit tea(MFT) to be used as an anti-inflammatory agent. Here, MFT was consumed by thirty middle-aged women with symptoms of rheumatoid arthritis for 4 weeks. The anthropometric measurements and serum inflammatory factors were measured before and after consumption of the MFT. For the anthropometric measurements, BMI and body fat decreased after 4 weeks of tea consumption although there were no significant differences. The serum inflammatory factors(uric acid and homocysteine) as well as serum amino transferase activity(aspartate trans-aminase and alanine transaminase) showed a decreasing trend. In addition, serum carbon reactive protein(CRP) decreased significantly decreased after MFT consumption 4 weeks. It's concluded that this MFT is helpful to for rheumatyroid arthritis patients in order to decrease serum inflammatory factors such as CRP.

Autotetraploid 'Sawonppong 26'was induced by dropping clochicine solution in growing point of Keomseolppong which is of high rootability and some agronomic charactelistics are as follows. Sawonppong 26 is a tetraploid of Keomseolppong with 56 of the chromosome number. Its fertlization percent was 59.4% and the germination percent of sank seed was normal. Sugar degree of mulberry fruit was 13.3% and total acidity was 0.69%. Single fruit weight of Sawonppong 26 was increased by 79%, as compared to that of Keomseolppong. Even though percent of survival of hard wood cutting was 94%, number of rootings was less and diameter of root was slender, it is expectedly a promising variety to be used for a breeding parent from the aspect of rootability.

The objective of this study was to evaluate the antioxidant effects and acetylcholinesterase (AChE) inhibition activity of mulberry fruit extracts prepared by hot water (MFH) and 80% ethanol (MFE). Total polyphenolic contents of MFH and MFE were $195{\pm}3.4\;mg$ gallic acid equivalents/g MFH and $185{\pm}2.8\;mg$ gallic acid equivalents/g MFE. MFH and MFE significantly quenched 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide dose-dependently, and showed high chelating ability and reducing power in non-cellular systems. MFH and MFE also inhibited the formation of intracellular reactive oxygen species and lipid peroxidation, and elevated intracellular glutathione (GSH) levels in RAW264.7 cells. In addition, MFH and MFE also dose-dependently suppressed AChE activity.

Recently mulberry has been commercialized but it loses its marketability rapidly after harvest. In this study, characteristics of mulberry were examined at different storage temperature after harvest using the typical Korean mulberry cultivars. Postharvest spoilage fungi on the various mulberry cultivars, Cheongilppong, Daeshim, and Gwasang No. 2 was observed 2, 2, and 1 d, respectively, after harvest at 28℃. However, at 4℃, the day was 8, 7, and 4 d, respectively. At 28℃ storage condition, the weight loss behavior of mulberry did not showed significantly different among them. However, at 4℃ storage condition, mulberry Cheongilppong loses its weight rapidly compared to Daeshim and Gwasang No. 2. Sugar content of mulberry stored at 4℃ was nearly constant, but stored at 28℃ decreased with storage time. The acidity of mulberry slightly decreased with storage time and then increased. Juice leakage of frozen mulberry leaked abruptly within 6 h from the fruit body and then flattened at 25℃. The results of our study, the postharvest characteristics of mulberry were affected by mulberry cultivar and need to further study to increase the shelf life.

In a previous study, a mulberry fruit extract(MFE) supplement exhibited anti-inflammatory activity and improved serum lipid profiles in arthritic rats. The objective of this study was to determine whether dietary MFE could ameliorate inflammatory parameters and serum lipid levels in humans. Twenty-six middle-aged subjects(mean body mass index=27 $kg/m^2$) consumed MFE(100 $m{\ell}/day)$ after lunch for 4 wks. Anthropometric measurements, serum oxidative stress markers and serum lipid profile analyses were performed at baseline and then at 4 wk following the study. There were no significant differences in anthropometric measurements, including BMI, WHR, and body fat composition. After the 4 wk-intervention, serum levels of C-reactive protein(CRP), ferric-reducing ability of plasma(FRAP), serum triglyceride(TG) and LDL-cholesterol had significantly decreased(p<0.05), whereas serum levels of HDL-cholesterol significantly(p<0.05) increased. These findings suggest the consumption of mulberry extract may be protective against inflammation and the atherosclerotic state in elderly obese men at high risk for cardiovascular disease(CVD).

뽕잎과 오디를 물, 50% 에탄올, 100% 에탄올 용매를 이용하여 microwave로 추출하여 이의 생리활성을 측정하였다. 뽕잎과 오디의 전자공여작용의 측정결과 모두 용매별 차이를 보였으며, 물과 50% 에탄올 추출물에서 $65.22{\sim}81.77%$로 높은 활성을 보였다. Tyrosinase는 $20.25{\sim}21.13%$로 20% 내외의 결과를 보였으며 용매별 차이는 없었다. SOD 유사활성 측정결과 뽕잎과 오디 모두 에탄올 농도가 증가할수록 활성이 감소하는 경향을 보여 물 추출물의 활성이 높게 나타났다. ACE 저해작용의 경우 모든 추출물에서 뽕잎보다 오디의 활성이 높게 나타났다. 전자공여작용, tyrosinase저해작용, SOD 유사활성 모두 물과 50% 에탄올 추출구에서 상대적으로 높은 활성을 보였으나, ACE 저해 작용의 경우 100% 에탄올 추출구에서 가장 높은 활성을 보였다. 아질산염 소거능은 pH의 증가에 따라 그 활성이 감소하는 경향을 보였다. 결론적으로 뽕잎과 오디 추출구의 경우 SOD 유사활성, 티로시나제 저해 효과, ACE 저해활성, 아질산염 소거작용에서는 낮은 결과를 보였지만 어느 정도의 활성을 보였으며, 우수한 전자공여작용이 있는 것으로 판단되므로 추출 시 시료의 양이나 추출물의 농도를 조금씩 높여 준다면 천연 항산화제로서의 이용가능성을 높일 수 있을 것으로 판단되었다.

The principal objectives of this study were to analyze the physiochemical properties of four mulberry fruit beverages (MFBs) and develop descriptive analysis procedures for evaluation of their sensory characteristics. Soluble solid, free sugar, pH, acidity, chromaticity, flavonoid, and anthocyanin of MFBs were determined. All MFB samples showed significantly different physicochemical properties ($p$<0.01). Ten highly trained panelists identified the following 11 sensory attributes in the MFBs and defined the terminology for each attribute : turbidity, chromaticity for appearance characteristics, berry, grass, fermented, sweet, astringent, and sour for flavor characteristics, and throat hit, refreshing, and astringent for textural characteristics. There were significant differences in the 10 sensory attributes among the MFB samples ($p$<0.001). In color, the value of MFB3 was significantly higher than those of others ($p$<0.05). In taste and overall acceptance, the values of MFB2 were significantly higher than those of others ($p$<0.01, $p$<0.001). Descriptive terminology of the developed MFBs could explain the sensory attributes of the samples according to this result. Based on this, proper analysis and sensory evaluation techniques could be applied to other fruit beverages to establish their physiochemical characteristic and descriptive sensory attributes.

재성형 뽕잎오디혼합쌀 개발과 관련하여 당뇨유발쥐와 고지방식이를 급여한 흰쥐에게 뽕잎오디쌀이 혈당농도와 체지방 및 혈청 지질 농도 등에 미치는 영향을 조사하였다. 혈당실험에서 뽕잎오디쌀조성물은 곡류와 잡곡류 등 85%, 뽕잎과 오디즙 15%로 구성하였고, AIN-diet와 50:50 비율로 혼합하여 4주간 급여한 결과 뽕잎오디쌀 급여군은 당뇨대조군보다 실험종료 시 체중은 28% 증가한 반면 공복혈당치는 12.4%, 혈청 중성지방 농도는 34% 감소하였다(p<0.05). 지질실험의 경우 4주 동안 고지방식이(50%)와 뽕잎오디쌀조성물(50%)의 혼합식이와 고지방식이(50%)와 기본식이(50%)의 혼합식이를 급여한 결과 뽕잎오디쌀 급여군은 고지방대조군에 비해 체중과 체지방(EFP)이 각각 8%씩 낮았고, 혈청 중성지방 농도는 약 19% 감소하였다(p<0.05). 이상에서 뽕잎오디쌀식이는 혈당저하 및 중성지방을 감소시키는 것으로 나타났고, 유의성은 없었으나 다소간 체중과 체지방 감소 효과를 확인할 수 있었다.

2017년도에서 2018년도까지 오디 생산용 뽕나무에 발생하는 주요 병해충 발생양상을 조사하였다. 병은 균핵병 등 5종, 해충은 뽕나무이 등 4종이 수확 전에 피해를 주는 것으로 조사되었다. 본 연구에서는 가장 큰 문제를 일으키는 균핵병과 뽕나무이에 의한 피해를 예방하기 위해 약제 체계별 방제효과를 조사하였다. 균핵병과 뽕나무이를 동시에 방제하기 위한 체계처리 결과는 관행방제구의 방제효과가 66.7%이었던 반면 종합방제구는 89.3%로 방제효과가 우수하였다. 실험 결과를 바탕으로 균핵병 예방을 위해 2월부터 순차적으로 약제를 처리하면서 4월 중하순에 균핵병과 뽕나무이를 동시방제하는 것이 방제에 필요한 노동력도 경감하고 병해충 발생생태에 맞춘 방제방법으로 오디 생산 현장에서 활용도가 높을 것으로 생각된다.

We bred a mulberry cultivar named Shimgang, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four local places(Suwon, Chuncheon, Buan and Jinju) for five years from 2011. This variety 'Shimgang' belongs to Morus Microphylla Buckl. selected from seedlings imported from USA. Shimgang was resistant to popcorn disease and high yielding variety in fruit productivity by 111% compared to control cultivar 'Shimheung(Morus alba L.)' for three years. Although fruits of 'Shimgang' was smaller in size and lower in sugar content of mulberry fruits, it showed stronger resistance than that of 'Shimheung'. It is adaptable to every where except the places where cold and late frost damage happen frequently.
