This study provides data to explore functional medicinal food materials that can prevent adult diseases, and verified antioxidant and anti-inflammatory of each solvent fraction of the methanol extract of Salvia plebeia R. Br. in Korea. In the analysis of total phenol content, DPPH radical scavenging ability, and FRAP reduction ability as indicators of antioxidant activity, the methanol fraction and ethyl acetate fraction of the Salvia plebeia R. Br. group showed high antioxidant activity. Ethyl acetate fraction of Salvia plebeia R. Br. methanol extract also showed excellent antioxidative activity as compared with BHT. In the mouse macrophage line Raw 264.7 cells, the NO production ability by LPS treatment was significantly increased in the LPS treatment group compared to the untreated group. In inflammatory reactions induced by LPS treatment in Raw 264.7 cells, inflammatory cytokines (TNF-α, PGE2, IL-1β) and NO production were decreased in the EtOAc fraction and MeOH fraction of the methanol extract of Salvia plebeia R. Br. compared to the case of LPS treatment alone. The anti-inflammatory effect was proved by significantly inhibiting the production of inflammatory cytokines. The present results suggest that Salvia plebeia R. Br. supplementation is beneficial for the suppression of antioxidant and anti-inflammation.

Objective: To investigate the possibility of hepatotoxicity by supplemental foods or folk herbs such as Salvia Plebeia R. Br. Methods: A hospitalized male patient with alcoholic liver disease and electrolyte imbalance had recovered, and then followed by rapid hepatic serum enzymes after taking S. Plebeia. This study monitored the clinical outcome and biochemical parameters. Result: A 58-year male had drunk frequently, which led to alcoholic steatohepatitis and hospitalization. Two weeks after his discharge from hospital, he felt nausea, dizziness, and mild difficulties in speech and walking, resulting in re-hospitalization at the Korean Medical Hospital. The symptoms disappeared on correction of the electrolyte imbalance suspected to have been caused by severe sweating while working in the outdoors, and the patient was discharged. During treatment and monitoring of his health as an outpatient, the serum hepatic enzyme rapidly elevated approximately 10-fold in hepatic enzymes; the enzyme levels fluctuated according to whether or not he was taking the boiled water of S. Plebeia. The RUCAM score was 12, which met the criteria for toxic hepatitis by S. Plebeia. His general condition and abnormal hepatic enzymes recovered with cessation of S. Plebeia and administration of Chungganplus syrup (CGX). Conclusion: This study reports the hepatotoxic risk of Salvia Plebeia, which is commonly used as a folk remedy in Korea.

The Salvia plebeia R. which is the biennial plant belonging to the labiatae department, grows widely in Korea. This study was performed to evaluate the antioxidant activities and anti-allergic effects of Salvia plebeia R. leaves (SPLE) or roots (SPRE). Using ethanol extracts, both leaves and roots induced significant radical scavenging activity against DPPH and ABTS radicals in a dose dependent manner (p<0.05). Superoxide dismutase (SOD)-like activity of SPLE was significantly higher than that of SPRE at all concentrations. Treatment of the RBL-2H3 cells with SPLE and SPRE in vitro decreased ${\beta}$-Hexosaminidase release and significantly inhibited IgE-antigen complex-mediated IL-4 and TNF-${\alpha}$ mRNA expression in RBL-2H3 cells. These findings suggest that Salvia plebeia R. can protect or reduce allergic asthma through high antioxidant and anti-allergic reactions.

This study looks into the dyeing properties and functionality of cotton fabrics dyed in both the Spirodela polyrhiza extract and the extract resulting from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza. Since the UV-Vis Spectrum of the methanol extract of Spirodela polyrhiza shows absorption peaks at 256, 268nm, and 345nm, it can be inferred that the compound that Spirodela polyrhiza contains is a flavonoid. In addition, it can also be presumed that, by analyzing the infrared absorption spectrum of Spirodela polyrhiza, the plant contains flavonoid compounds, just like Salvia plebeia R. Br.. The UV protection factors of the cotton fabrics dyed in both the Spirodela polyrhiza extract and the extract from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza were 50+, presenting outstanding UV protection factors. The deodorization rate of the cotton dyed in the Spirodela polyrhiza extract was between 30 and 120 minutes, and the rate rose from 92% to 97% as time passed. The deodorization rate of the cotton dyed in the extract from the mixture of Salvia plebeia R. Br. and Spirodela polyrhiza increased from 88% to more than 91%. The result also revealed that overall the fastness of color, including color fastness to washing related to change in color, as well as the color fastness to light of the fabric dyed in the extract from the mixture of the two plants improved, compared to the cloth dyed only in Spirodela polyrhiza extract. Furthermore, the antibacterial activity was also strengthened.

Background: In the present study, we established an HPLC (high performance liquid chromatography)-analysis method for the determination of marker compounds as a part of the material standardization for the development of health-functional foods from Salvia plebeia R. Br. extract. Methods and Results: The quantitative determination method of hispidulin as a marker compound was optimized by HPLC analysis using a YMC hydrosphere C18 column with a gradient elution system. This method was validated using specificity, linearity, accuracy, and precision tests. It showed a high linearity in the calibration curve with a coefficient of correlation ($r^2$) of 0.999995. The method was fully validated, and was sensitive, with the limit of detection (LOD) at $0.09{\mu}g{\cdot}m{\ell}^{-1}$ and limit of quantification (LOQ) at $0.27{\mu}g{\cdot}m{\ell}^{-1}$. The relative standard deviation (RSD) values of the data from intra- and inter-day precision were 0.05 - 0.22% and 0.32 - 0.42%, respectively, and the intra- and inter-day accuracy of hispidulin were 99.5 - 102.3% and 98.8 - 101.5%, respectively. The average content of hispidulin in Salvia plebeia R. Br. extract was $3.945mg{\cdot}g^{-1}$ (0.39%). Conclusions: These results suggest that the developed HPLC method is very efficient, and that it could contribute to the quality control of Salvia plebeia R. Br. extracts as a functional ingredient in health functional foods.

Background: We recently reported that Salvia plebeia R. Br. extracts suppress leukotriene production and effectively inhibit the airway inflammatory response by modulating inflammatory chemokine and cytokine expression. Here, we investigated the synergistic airway anti-inflammation effect of Salvia plebeia and Panax ginseng (Korean red ginseng, KRG) that has been used to treat various immune diseases such as asthma. Methods and Results: To evaluate the synergistic airway anti-inflammatory effect of Salvia plebeia and KRG, we measured the inhibitory effect of monotheraphy with either or co-theraphy with both on leukotriene and reactive oxygen species (ROS) production. Using coal a combustion, fly ash, and diesel exhaust particle (CFD)-induced respiratory disease mouse model, we found that co-theraphy synergistically suppressed airway inflammatory signs such as alveolar wall thickness and collagen fibers deposition, and decreased the number of total cell, $CD11b^+Gr-1^+$ cells, and inflammatory cytokines (IL17A, TNF, MIP-2 and CXCL-1) in bronchoalveolar lavage (BAL) fluid. Conclusions: We confirmed respiratory protection as a therapeutic effect of the Salbia plebeia-KRG 3 : 1 complex (KGC-03-PS) via anti-tracheal muscle contraction and expectorant animal studies using a CFD-induced respiratory disease mouse model.

This study was carried out to investigate the effects of Salvia plebeia R. Br. ethanolic extract with different aspects (stem/leaf and whole plant) on differentiation and lipid accumulation in 3T3-L1 preadipocytes. The morphological changes and the degrees of lipid accumulation in 3T3-L1 cells were measured by Oil Red O staining and intra-cellular triglyceride (TG) assay. The mRNA expressions of special peroxisome proliferation activated receptor- genes (PPAR), CCAAT/ enhancer-binding protein (C/$EBP{\alpha}$), fatty acid synthase (FAS) and lipoprotein lipase (LPL) were detected by reverse transcriptase polymerase chain reaction (RT-PCR). The 50% ethanolic extracts ($100{\mu}g/mL$) of stem and leaf (SALE) and 30% ethanolic extracts (100 g/mL) of whole plant (SAE) from Salvia plebeia R. Br. were significantly attenuated lipid accumulation during adipogenesis in 3T3-L1 cells. Ethyl acetate-soluble fractions ($50{\mu}g/mL$) significantly inhibited lipid droplet accumulation in 3T3-L1 cells. In addition, SALE induced down-regulation of specific adipogenic transcriptional factors (C/$EBP{\alpha}$ and $PPAR{\gamma}$) and target genes (FAS and LPL) during adipogenesis. Salvia plebeia R. Br. may be used as a safe and efficient natural substance to manage obesity.

This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.
