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.

Purpose: We examined the effects of Dansam (Salvia miltiorrhiza Bunge, SM) and Dansam-eum (DSE) on gastroesophageal reflux disease (GERD) and reflux esophagitis by comparing the inhibitory effects of SM and DSE with the representative treatment of PPI Omeprazole to determine if the effects of the prescription DSE based on Korean medicine are better than those of a single-use of SM. Methods: We performed experiments using both animal models and cancer cells. Results: Comparison of SM and DSE with PPI in the animal model tests revealed that the effects were superior for SM and DSE than for PPI in all categories (8-OHdG, p-IκB, PAR2, COX-1, cathelicidin, p-JNK, Caspase 3, ATP6V1B1, GRPR, serotonin, and NPY). In three categories (COX-1, serotonin, and NPY), SM and DSE showed superior results over the Controls. In the animal model tests, DSE was superior to SM in all categories except for serotonin. The anti-cancer effects observed in cancer cell tests revealed that SM and DSE had meaningful results in terms of cytotoxicity and cell movement rate, as well as in cancer cell apoptosis. Conclusions: We confirmed that SM and DSE can have effects on reflux esophagitis through the regulation of oxidative stress, inflammation, mucosal protection, apoptosis, proton pumping, and the enteroendocrine system in the stomach and esophagus. We also confirmed that SM and DSE have superior effects to those of PPI on all aspects, especially gastric mucosa protection and enteroendocrine system control. We also confirmed that SM and DSE have anti-cancer effects. Above all, we confirmed that DSE has superior effects on almost all aspects compared to using SM alone.

This research was conducted to investigate the antibacterial and anti-inflammatory effects of MeOH Ex. of Salvia miltiorrhiza (MESM) against oral pathogenic bacteria. Minimum inhibitory concentration (MIC), removal effect of biofilm produced by Streptococcus mutans, effect of gene expression of proinflammatory cytokines and effect of production of proinflammatory cytokine of MESM were tested. MESM showed moderated antibacterial activity against oral pathogenic bacteria. About 89±8% of biofilms produced by S. mutans were removed by MESM at a concentration of 1 mg/mL. Gene expression of IL-1β and TNF-α induced by Porphyromonas gingivalis were 8~9 folds reduced by MESM. Gene expression of IL-8 induced by Fusobacterium nucelatum were 12 folds reduced by MESM. Production of IL-1β, TNF-α and IL-8 were significantly suppressed by MESM. Conclusively, MESM showed potent antibacterial and anti-inflammatory effect against oral pathogenic bacteria.

This study was carried out to investigate the variation of growth and yield using different planting densities and vinyl mulching in S. miltiorrhiza cultivation. Top plant growth was observed in the $30{\times}30cm$ planting density of S. miltiorrhiza;, plant height, leaves and branches were larger than in the other treatments. Root length, root diameter, and supporting roots of underground part were increased as planting density was wide, and dry root weight was increased in $30{\times}30cm$. However, yield was highest at 294 kg/10a in the planting density of $30{\times}10cm$. The use of 30-31cm white and black vinyl mulching had no significant effect on the plant height of S. miltiorrhiza, as compared to non-mulching. However, the highest volume of leaves and plant weight was observed in plants using 24.7 black vinyl mulching. Dry underground root weight was highest in black vinyl mulching at 21.7 g compared to 17.0 g for non-mulching. Yield per 10a increased by 28% using black vinyl mulching compared to non-mulching. Based on the results of this study, planting density of $30{\times}10cm$ and black vinyl mulching are the most suitable in the cultivation of S. miltiorrhiza.

Six fractions of Salvia miltiorrhiza were tested for their chemopreventive potentials using biochemical markers of carcinogenesis such as quinone reductase (QR), glutathione S-transferase (GST) and glutathione (GSH). Seventy percentage of EtOH extract was potent inducer of QR activity in Hepa1c1c7 murine hepatoma cells. GST activity was increased about 1.4-fold with EtOAc extract at concentration of 50 ${\mu}g/ml$. GSH levels were significantly increased with $H_2O$ extract, 70% EtOH extract and water extract at concentration of 50 ${\mu}g/ml$ (p<0.005). From these results, 70% EtOH extract (250 mg/kg) was intragastrically administered to ICR mice for 14 days. QR, GST and GSH levels were significantly increased with the 70% EtOH treatment. These studies suggest that the 70% EtOH extract of S. miltiorrhiza could be considered as a potential agent for cancer chemoprevention.

The preventive effect of Salvia miltiorrhiza extracts (SM) with or without high molecular weight soluble kitosan (K) on the progress of bone loss induced by ovariectomized (OVX) was studied in rats. From light microscopic analyses in histochemistry data, trabecular bone area in OVX rats was significantly decreased compared with that in sham rats. The decrease was regulated by administration of SM and especially the combination of SM and K (SM + K) for 7 weeks. In addition, the numbers of osteoblasts and osteoclasts were regulated in SM + K-administered rats but not different from those in either SM or K-administered rats. In OVX rats, free Triiodothyronine ($T_3$) and Thyroxine ($T_4$) were similar to control, ruling out the involvement of abnormal thyroid hormone. Although serum calcium is similar among all the groups, estrogen level was higher especially in SM+K-administered rats. These results strongly suggest that SM+K are effective in preventing the development of bone loss induced by OVX in rats.

This study was carried out to investigate the effects of herb extracts on lipid oxidation and free radical reaction in iron sources reacted with active oxygen species. The catalytic effects of active oxygen on lipid oxidation in oil emulsion tended to show more active in the order of OH, H2O2 and KO2. Herb extracts tended to show a little catalytic effect and active oxygen scavenging ability of herb extracts didn't show. But herb extracts played role as a strong chelating agents to bind iron if Fe2+ ion exist in oil emulsion. The contents of Fe2+ ion and total iron in Salvia miltiorrhiza Bge. and Angelica gigas Nakai were higher than those of Prunus persica Stockes and pinus strobus. The content of asocrbic acid in Pinus strobus showed the highest (26.97ppm) among several herb extracts. Electron donating abilities of Pinus strobus and Salvia miltiorrhiza Bge. were 79.54% and 77.11%, respectively, which were higher contents than those of Prunus persical Stokes and Angelica gigas Nakai. The SOD-like activity of Prunus persca Stokes showed 0.16 optical density (O.D), which means the most strong antioxidant activity among other herb extracts. The nitrite scavening effects tended to be different depending on pH. Pinus strobus and Angelica gigas Nakai showed 99.8% and 98.6% nitrite scavening effects at pH 1.2. And the effects were decreased as pH was increased. Especially, they didn't show the nitrite scavenging effect in pH 6.0. In conculsin, the Prinus strobus extract among herb extracts were the most effective antioxidant by evaluating several functional tests.
