  • This study was designed to investigate the effects of mulberry leaf powder supplementation on lead (Pb) status and mineral (Ca, Fe, Cu and Zn) content in Pb-administered rats for 4 weeks. Thirty two male rats were divided into 4 groups: a control, Pb, Pb5M (500 ppm $Pb + 5\%$ mulberry leaf powder), and Pb10M (500 ppm $Pb + 10\%$ mulberry leaf powder). There were no significant differences in food intake and initial body weight among groups. Mulberry leaf powder treatments showed significant decreases in food efficiency ratio and body weight gain. But FER of $Pb5M\%$ and Pb10M were significantly increases than that of Pb group. The levels of serum aspartate transaminase (AST) and creatinine were decreased by mulberry leaf powder treatment. Minerals content of liver and kidney were significantly decreased in the Pb groups than that of control group. Whereas, fecal minerals content were significantly increased in the Pb5M and Pb10M than those of control group. Pb content of serum, liver and kidney was significantly increased in the Pb group than those of control group. However, by mulberry leaf powder administration (Pb5M and Pb10M), Pb level of serum, liver and kidney were lowered than that of Pb group. And fecal Pb excretion was significantly increased in the Pb5M and Pb10M than that of Pb group. These results showed mulberry leaves were effective for lowing Pb accumulation in serum, organs, which may have potential to prevent Pb toxicity.

  • This study was aimed to analyze the composition and to quantify the contents of stilbenoids in the leaves and fruits of Morus alba L. using high performance liquid chromatography with phodtodiode array detector and UV detector. Optimal wavelength for the detection of various stilbenoids such as resveratrol, piceatannol, rhapontigenin, astringin, pterostilbene, piceid, rhaponticin and vitisin A was screened by DAD detector and set to 308 nm. Seven kinds of stilbenoids except vitisin A were identified in fruits, while 5 kinds of stilbenoids in leaves. Total stilbenoids contents were $609.15{\pm}7.24$ mg/100 g d.w. in fruits and $188.57{\pm}1.70$ mg/100 g d.w in leaves. Stilbenoids contents in fruits were 3 times higher than those in leaves. Rhaponticin was the most profound stilbene, analyzed to $389.26{\pm}5.22$ mg/100 g d.w. (63.8% of total stilbenoids) in fruits and $99.17{\pm}2.79$ mg/100 g d.w. (52.5% of total stilbenoids) in leaves. Astringin and piceatannol were only detected in fruits and vitisin A was not detected. Contents of piceid and rhaponticin were higher than those of aglycone forms, rhapontigenin and resveratrol.

  • Morus alba, known as White Mulberry, is one of the most common species of mulberry found in South Korea, along with M. australis, known as Korean Mulberry. During a routine survey to investigate fungal diseases on deciduous broad-leaved trees in 2020, leaf spots were consistently observed on the White Mulberry in Sejong-si (36°30'12.8"N 127°17'34.5"E) and Wonju-si (37°15'29.6"N 128°11'37.9"E), South Korea, with a disease incidence of approximately 70 to 80%. Symptoms included circular, tan or necrotic lesions surrounded by a dark margin on leaves, which, in some cases, the lesions coalesced to form relatively large necrotic regions. The pathogen was successfully isolated from M. alba, and was identified as Cladosporium pseudocladosporioides based on the phylogenetic analysis and morphology. To the best of our knowledge, this is the first report of leaf spot disease on M. alba caused by C. pseudocladosporioides in South Korea.

  • Objectives This experimental study was designed to investigate the effects of Mulberry leaves contained herbal mixture (MLHM) on body weight, serum lipid level and adipocyte differentiation in high fat diet-fed obese mice. Methods Four-week old mice (wild-type C57/BL6) were used for all experiments. Cells were incubated with MLHM at the indicated concentration (0.04-4mg/ml) for 24h, and growth rate was assessed by MTT ((3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. 3T3-L1 preadipocytes were incubated in DMEM for 2 days with the indicated concentrations of MLHM, and on Day 6, the cells were fixed and the cellular lipid contents were assessed by Oil-Red-O staining. The expression of peroxisome proliferator-activated receptor ${\gamma}$ (PPAR ${\gamma}$) and cytidine-cytidine-adenosine-adenosine-thymine (CCAAT)/enhancer-binding proteins ${\alpha}$ (C/EBP ${\alpha}$) as adipocyte-specific proteins were determined by real time RT-PCR and western blotting. In addition, body weight gain and serum lipid levels were measured in the mice with obesity induced by the high fat-diet for four weeks. Results Though MLHM did not show toxicity even at the concentration of 4mg/ml, MLHM significantly inhibited the differentiation of 3T3-L1 preadipocites in a dose-dependent manner. Also, MLHM significantly reduced the expressions of PPAR ${\gamma}$ and C/EBP ${\alpha}$ in a dose-dependent manner. Furthermore, MLHM significantly reduced body weight gain and LDL-cholesterol contents in high fat diet-fed obese mice. Conclusions These results demonstrate that MLHM exerts anti-obesity effect in 3T3-L1 cells and mice with obesity by high-fat diet.

  • We investigated the effects of Mulberry leaves fermented enzyme liquid(MLE) addition on the quality of Kimchi which were fermented at $5^{\circ}C$ during 30 days. MLE was added to salted cabbage at concentrations of 0%(C), 0.4%(MLE1), 0.8%(MLE2), and 1.2%(MLE3) (w/w). pH in Kimchi added upon 1.2% of MLE, was higher than that of Kimchi without MLE after 12 days of fermentation. The titratable acidity was increased by the addition of MLE, and particularly Kimchi added 1.2% of MLE showed the slowest changed level. The degree of salinity were decreased in Kimchi with MLE as well as control group. However, MLE1 showed significantly lower salinity than MLE2, MLE3 and control group (p<0.001). L, a, b values of control group indicated significantly higher than the Kimchi with enzyme liquid concentrations(MLE1~MLE3). As compared with the control group, the cutting force in treated groups were increased during the fermentation period, and especially MLE3 showed the highest value of hardness. Moreover, that growth of lactic acid bacteria and total bacteria were inhibited by the addition of MLE. In the sensory assessment, the color, taste, and overall preferences were higher in MLE2 than control group and MLE1, MLE3. The acceptability of MLE as an additive in Kimchi among middle school students was higher than in the control sample, with an optimum additive of 0.8% MLE, based on the lowest volume of leftovers. Therefore, it was confirmed that addition of 0.8% MLE appears to be an acceptable approach to enhance the quality of Kimchi without reduction of acceptability.

  • For development of premium sauce, fermented sauces containing ferment (with wheat flour and soybean) and extract(s) of Styela clava (Korean name: miduduk) tunic and/or mulberry leaves and/or onion were prepared, and their angiotensin converting enzyme (ACE) inhibitory and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities were evaluated. All sauces containing extract(s) showed increased ACE inhibitory and DPPH radical scavenging activities. Especially, sauces containing extracts of mulberry leaves and onion showed superior activities, with 26.92% and 40.66% relatively increased ACE inhibitory and DPPH radical scavenging activities, respectively, compared to control (no extract was added). These results suggest that extracts of mulberry leaves and onion could improve antihypertensive and antioxidant activities of fermented sauce.

  • In this study, the effects of Mulberry leaves extract (ME) addition on the quality of Kimchi was investigated during 30 days of fermentation at $5^{\circ}C$. ME was added to salted cabbage at concentrations of 0% (C), 0.4% (ME1), 0.8% (ME2) and 1.2% (ME3) (w/w). The pH of Kimchi added above 0.8% ME was higher than that of Kimchi without ME after 12 days of fermentation. During overall fermentation, the titratable acidity of Kimchi with 1.2% ME remained at the lowest level. The degree of salinity decreased with increasing amount of added ME, whereas control groups showed the highest salinity. In L, a and b values of samples, the highest Figures of L and b were observed in control groups, and ME3 showed the highest value of a. In addition, the cutting force during the fermentation period was higher in all treated groups compared with control groups, and ME3 showed the highest hardness value. Moreover, growth of lactic acid bacteria and total bacteria were inhibited by addition of ME. In the sensory assessment, 0.4% ME improved the quality of Kimchi, showing the highest taste score and overall preference. Therefore, addition of 0.4% ME appears to be an acceptable approach to enhance the quality of Kimchi without reduction of acceptability.
