In this study, Salvia miltiorrhiza Bunge(Danshen) powder was extracted with ethanol, and its antimicrobial activity was investigated. The ethanol extract of the Danshen had antimicrobial activity against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus. The inhibition zones of the Danshen extract(3 mg/disc) against B. subtilis, E. coli and S. aureus were 13, 12 and 8.5 mm, respectively. To test the food preservation effect of Danshen and determine the optimal ratio of the Danshen extract in a formulation, Sulgidduk samples were prepared with substitutions of 0, 0.25, 0.5, 0.75 and 1% Danshen extract, and then their quality characteristics were investigated over 4 days of storage. According to the results, total cell counts showed a decreasing trend with an increasing amount of added Danshen extract. Moisture contents were not significantly different among the Sulgidduk samples. As the content of Danshen extract increased, the L-values of samples decreased and the a- and b- values increased. For the textural characteristics, the hardness, gumminess, and chewiness of the Sulgidduk samples decreased as the amount of Danshen extract increased; however, they increased with the progression of storage time. In the sensory evaluation, the control group had significantly higher scores for color, flavor and after-taste as compared to the Danshen extract-added groups. With increasing Danshen extract contents, flavor and overall acceptability decreased, while Danshen flavor, bitterness and off-flavor increased. Chewiness was not significantly different among the samples. In conclusion, the results indicate that substituting 0.5% Danshen extract in Sulgidduk is optimal for quality and provides a product with reasonably high overall acceptability.

To improve the utilization of the domestic plant Salvia miltiorrhiza Bunge (Danshen), this study investigated changes in the physicochemical qualities of Danshen extracts obtained from low-temperature extraction using the enzymes amylase, cellulase, pectinase, and protease. Changes in the yield, pH, sugar content, and chromaticity were investigated. The changes were found to be highest in the amylase-treated extract with the following values: yield, 58.3%; pH, 6.04; sugar content, $5.97^{\circ}Brix$. With regard to antioxidant properties, Danshen extracts treated with amylase showed the highest DPPH and ABTS scavenging activities of 84.25% and 74.11% at 55 ppm. The total phenolic compound content was highest in the group subjected to enzyme treatment at $60^{\circ}C$. The salvianolic acid B level of the Danshen extract was the highest in the amylase-treated group, with a value of 3,002.6 mg/100 g. Cryptotanshinone level was the highest in the amylase- and protease-treated group with a value of 3.8 mg/100 g. Tanshinone I was the highest in the protease-treated group, with a value of 14.2 mg/100 g. The results showed that the indicator components of Danshen were detected as stable in the extracts after using amylase for low-temperature extraction; therefore, it would be possible to use Danshen industrially as a functional ingredient through mass production. Furthermore, the enzyme-treatment extraction could be utilized for a variety of natural products.

In this study, we investigated effects of Monegy (mixture of Sophorae Radix, Panax ginseng, Salvia miltiorrhiza BUNGE) on epilate-induced hair-loss in dorsal region of C57/BL6 mice and external structure of human hair. For morphological and histological analysis in scalp of epilate-induced hair-loss animal model, we utilized several microscopic techniques, such as confocal laser scanning microscopy (CLSM) and LAS 4000. Confocal analysis showed the distribution of FITC-conjugated Monegy and penetration depth compared with normal and control group. Furthermore, when Monegy was topically administrated onto a C57BL6 mouse, it penetrated very well. The fluorescence intensity was increased upto 205 and 113 folds compared to normal and control group, respectively. Also, area of fluorescence was increased to upto 255 to 127 folds compared to normal and control group. Broad scale area of fluorescence in dermis region was observed in the Monegy-treated mice. Furthermore, Monegy induced upto 75% hair repair against depilation. It might be promoted via the induction of growth factors in hair follicle.

This studies were carried out to investigate antimicrobial activity of 35 kinds of medicinal herbs against lactic acid bacteria isolated from home-made Kimchi. The most isolated lactic acid bacteria were inhibited by ethanol extract of various medicinal herbs such as Schizandra chinensis (SC), Salvia miltiorrhiza (SM), Glycyrrhiza uralensis (GU), Lithospermum erythrorhizon (LE) and Sophrora flavescens AITON (SF). But Cnidium monnier, Pinus densiflora, Paeonia suffruticosa, Acanthopanax sessiliflorum and Rhus chinensis inhibited the growth of only a few isolated lactic acid bacteria. The pH of Kimchi containing 1% of medicinal herbs extracts such as SM, GU, LE and SF was higher than that of control during fermentation for 25 days at $10^{\circ}C$, respectively. Titratable acidity and viable cells of total bacteria and lactic acid bacteria of the Kimchi were lower than that of control during fermentation. The sensory quality (taste, flavor and overall acceptability) of SM, GU, and LE added Kimchi was similar to that of control at 10th day of fermentation. But Sophrora flavescens AITON added Kimchi decreased significantly its sensory quality compared with control(P<0.05).

Objectives: We investigated the effects of Clean-DM4 (C-DM4), a polyherbal extract consisting of Coptidis Rhizoma, Salviae Miltiorrhiza Radix, and Cinnamomi Cortex on high fat diet (HFD)-induced obesity and diabetes in mice. Methods: The C57BL/6 mice (6 weeks) were fed a HFD for 8 weeks and then administrated with C-DM4 extract at 500 mg/kg (p.o.) once daily for 4 weeks. The changes of body weights, calorie intakes, and fasting blood glucose (FBG) levels were measured in mice. The serum levels of glucose, insulin, total cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured in mice by enzyme-based assay. It was also observed the histological changes of pancreas, liver, and fat tissues with hematoxylin and eosin (H&E) staining. Results: The increase of calorie intakes and FBG levels in HFD-induced obesity mice was significantly decreased by oral administration of C-DM4 extract. C-DM4 extract administration was significantly reduced the increased levels of glucose, insulin, total cholesterol, AST, and ALT in obesity mice. In addition, C-DM4 extract inhibited lipid droplet accumulation in liver tissues of obesity mice, hyperplasia of pancreatic islets, and enlargement of adipocytes in adipose tissues. Conclusions: Our study indicates that C-DM4 extract could help improve obesity and to prevent diabetes progression.

The role of the water structure present in hydrogels from nutlets of three species of salvias, S. miltiorrhiza (SM), S. sclarea (SS) and S. viridis (SV), was analyzed by differential scanning calorimetry (DSC). The sharp endothermic peaks that appeared at $5.9^{\circ}C$ (SM), $2.8^{\circ}C$ DC (SS) and $1.8^{\circ}C$ (SV) in each 1.0% hydrogel of 10.4-15.8% were not affected by addition of 0.1 M urea and alkali-metal salts. The order-disorder portions in the network were slightly affected by the distribution of freezable and non-freezable water in the hydrogel networks. The SV hydrogel was further used to investigate the effects of additives (0.1-8.0 M urea and 0.1-5.0 M NaCl) on its melting behavior. At 0.5-4.0 M urea and 1.0-3.0 M NaCl, two endothermic peaks appeared, corresponding to unbound (high temperature) and bound (low temperature) water in the gel networks, and eventually merged into one endothermic peak at 5.0-8.0 M urea and 4.0-4.5 M NaCl. After this merger, the endothermic peak shifted to 3.7, 4.0 and $5.6^{\circ}C$ at 5.0, 6.0 and 8.0 M urea, respectively. In the case of NaCl, a combination of peaks that occurred at 4.0-4.5 M were accompanied by a shift to lower temperature (-14.4 and $15.3^{\circ}C$) and the endothermic peak finally disappeared at 5.0 M NaCl due to the strong binding of water in the gel networks.

This study investigated the effect of traditional medicinal plants on the quality characteristics of Samgyetang breast meat and broth. The traditional medicinal plants used in this study were roots of Panax ginseng, Codonopsis lanceolata, Platycodon grandiflorum, Salvia miltiorrhiza, Adenophora triphylla, and Allium hookeri. There was no significant difference (P>0.05) in the moisture, protein, ash content, water holding capacity, and cooking loss of Samgyetang meat with the addition of traditional medicinal plants. The color values (lightness, redness, and yellowness) of Samgyetang meat and broth were significantly different (P<0.05); the 2-thiobarbituric acid reactive substances and shear force of Samgyetang meat were significantly different (P<0.05); and the pH, turbidity, and viscosity of Samgyetang broth were also significantly different (P<0.05) with the addition of traditional medicinal plants. In the overall acceptability of Samgyetang meat, the addition of S. miltiorrhiza showed the highest score compared to that of other treatments (P<0.05). Thus, the addition of traditional medicinal plants in the production of Samgyetang were found to affect the lipid rancidity beneficially with plant species when compared to Samgyetang with Panax ginseng. In conclusion, with the development of Samgyetang using S. miltiorrhiza, it will be possible to develop products with superior quality characteristics in antioxidant, shear force, and overall acceptability.
