This study was conducted to determine the cell cytotoxicity, astringency, nitrite oxide scavenging, iNOS protein expression level, pro-inflammatory cytokine, elastase inhibition, and type I pro-collagen synthesis as a functional cosmetics material of Salvia miltiorrhiza root. We prepared the 80% ethanol(SE) and hot-distilled water(SW), respectively. Both SE and SW showed no toxicity from 0.05 to 0.5 mg/mL concentration as a result of MTT assay in NHDF or RAW264.7 cells. In the measurement of astringent effect, SE reveled 74.6% of astringent activity in 10 mg/mL. SE showed that LPS-induced nitric oxide production, iNOS protein expression, and cytokines were inhibited in a dose-dependent manner. Furthermore, two extracts significantly inhibited elastase activity and increased the type I pro-collagen production. Therefore, it is expected that Salvia miltiorrhiza extract is used as a natural material for functional cosmetics that can effectively prevent skin-related inflammation and wrinkles, and aging.

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 Eucommiae Cortex, Salviae miltiorrhizae radix, Aurantii nobilis pericarpium and Cnidii rhizoma were carried out. Comparison of the four ethanol extracts revealed that, Aurantii nobilis pericarpium had the highest electron-donating ability(79.0%),; however, Salviae miltiorrhizae radix had the highest SOD-like ability(21.9%). The xanthine oxidase experiment exhibited a hindrance effect of 79.3% in Salviae miltiorrhizae radix, 57.5% in Eucommiae cortex and 71.9% in Aurantii nobilis pericarpium. A tyrosinase inhibitory activity assay was conducted to evaluate the whitening effects of the extracts, The tyrosinase inhibitory activity was 12.4% in the Eucommiae cortex, 22.8% in the Salviae miltiorrhizae radix, 27.5% in the Aurantii nobilis pericarpium and 59.5% in the Cnidii rhizoma. Based on these results, we suggest that the ethanol extracts of Eucommiae cortex, Salviae miltiorrhizae radix, Aurantii nobilis pericarpium and Cnidii rhizoma. can be used as food and cosmetic ingredients.

Salvia miltiorrhiza Bunge is known to potentially prevent arteriosclerosis and hypertension, but its effects on platelet function are not clear. In this study, we evaluated the in vitro antithrombotic activities of the edible plant extract. Methanol extract of S. miltiorrhiza Bunge exhibited about 70% fibrinolytic activity compared to the plasmin control, and inhibited ADP- and collagen-induced platelet aggregation in a concentration-dependent manner with $IC_{50}$ values of 0.42 and 0.07 mg/mL, respectively. S. miltiorrhiza Bunge extract significantly prolonged the activated partial thromboplastin time (APTT) and prothrombin time (PT) compared with control. Moreover, 0.05 mg/mL S. miltiorrhiza Bunge extract contained 87.3% l,l-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity. In conclusion, S. miltiorrhiza Bunge seemed to enhance antithrombotic activity due to its radical scavenging activity. Based on these data, further examination is required to determine the mechanism of platelet-dependent antithrombosis and the effect of polyphenols on platelet function.

The present study was carried out to investigate the antitumor activity of Salvia miltiorrhiza (SM) herbal extract in rat tumor model. We used a new tumor animal model for the invasion and metastasis of cancer using genetically k-ras-induced rat kidney cells (RK3E-ras). We observed tumor as early as 7 days after the injection of RK3E-ras cells in subcutaneous of Sprague-Dawley rats. All of the rats developed tumor mass at the inoculated site. After 7 days, the experimental groups were divided into two: saline control and injected with SM (200 mg/kg) groups. We investigated tumor's weight, size and hepatic metastasis of each group. Injection of SM herbal extract every other day for 14 days significantly inhibited tumor growth. Histologically, the tumors were undifferentiated carcinoma showing multifactorial necrosis and hemorrhage; also, the tumor invaded into hepatoportal region. Treatment with SM herbal extract caused significant inhibition of tumor cell proliferation. Our data showed that SM herbal extract is effective in controlling the tendency of tumor cell proliferation and metastasis by injection of RK3E-ras cells. These findings provided the potential value of SM as a novel antitumor agent candidate.

This study was performed to evaluate the antitumor activities of water and ethanol (EtOH) extract of Salvia miltiorrhiza in vitro and in vivo. The proliferation of the human hepatoma (HepG2), rectum cancer (HRT-18) and colon cancer (HT-29) cells was inhibited by administration of extracts in a dose-dependent manner. Particularly, EtOH extract inhibited proliferation of the cells more effectively than water extract did. The morphology of cells induced by EtOH extract was characterized by reduction of cell size and deformatin. Oral administration of the EtOH extract (3 mg/head) to tumor-bearing mice inhibited the tumor (sarcoma-180) growth by 35% and prolonged their survival rate by 61%. The EtOH extract was shown to be nontoxic at 37.5% mg/head/day on the acute toxicity test. These studies suggest that the EtOH extract of Salvia miltiorrhiza may have antitumor activity in vitro and in vivo.

Salvia miltiorrhiza Bunge (S. miltiorrhiza) is a traditional Korean medicine that is commonly used for the treatment of inflammatory diseases such as edema, arthritis, and hepatitis. The present study investigated the antimicrobial activity of methanol (MeOH) extract of S. miltiorrhiza roots against oral bacteria using broth the microdilution method and the checkerboard and time-kill methods evaluated the synergistic effects of treatment with antibiotics. The MeOH extract was demonstrated as a higher antibacterial activity (MICs, 8 to $64\;{\mu}g/mL$; MBCs, 16 to $64\;{\mu}g/mL$) against all tested oral bacteria. Additionally, the extract was observed to have a synergistic effect with ampicillin or gentamicin. A time-kill study evaluating the effects of the extract indicated that the extract treatment in combination with ampicillin or gentamicin showed rapid bactericidal activity. The results suggest that MeOH extract of S. miltiorrhiza could be employed as a natural antibacterial agent against dental caries.

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 order to search for new whitening cosmetic ingredients from Chinese herbal extracts including Chinese herbs and complex prescriptions from TCM (Traditional Chinese Medicine), we screened about 47 TCM extracts collected from China. We tested their inhibitory effects on melanogenesis by using in vitro tyrosinase inhibition assay and B16 melanoma cells. We selected Siphonostegia chinensis and Salvianic miltiorrhiza Bunge. We isolated Danshensu ($\alpha$,3,4-trihydroxybenzenepropanoic acid sodium salt) from Salvianic miltiorrhiza Bunge extract and tested its inhibitory effect on melanin formation in B16-F10 melanoma cells. Danshensu suppressed melanin synthesis up to about 50% at a concentration of $100\;{\mu}g/mL$. Siphonostegia chinensis suppressed melanin synthesis up to about 60% at a concentration of $300\;{\mu}g/mL$. The results showed that these extracts could be used as new natural active ingredients for whitening cosmetics.
