  • Acute toxicity of a combined preparation of the standardized extracts Scutellaria baicalensis GEORGI and Salvia miltiorrhiza BUNGE in a ratio of 3:1 was examined in male and female ICR mice. Mice were treated with the test substance intragastrically at a dose of 0 mg/kg, 5 mg/kg, 50 mg/kg, 500 mg/kg or 2,000 mg/kg and observed for two weeks. No death or abnormal clinical sign was shown during the observation period. Also there were no difference in net body weight gain, organ weight, and gross pathological findings at the terminal sacrifice. The results suggested that acute oral toxicity of a combined preparation of the standardized extracts is very low at the conditions employed in this study.

  • The Mixed effect of Salvia miltiorrhiza and Glycyrrhiza uralensis(SG) on kimchi fermentation was investigated by measuring changes of physicochemical, icrobiological and sensory qualities of kimchi during fermentation. The pH of SG-added kimchi was a little higher than that of control during the fermentation. Titratable acidity, viable cell of total bacteria and lactic acid bacteria in mixed medicinal herbs(SG) added kimchi were changed more slowly than those in control. The inhibitory effect of the mixture on kimchi fermentation was increased as the concentration of the mixture was increased from 1% to 5%. Total bacteria and lactic acid bacteria of 3% and 5% SG-added kimchi reduced to 1.3~2.9 and 1.2~4.0 log10 cycle after 15 days fermentatin compared to control. The changes in texture of SG-added kimchi was a higher and sour taste of SG-containing kimchi excepts of 1% SG-added kimchi was more weak than that of control. Sensory score of flavor and overall acceptability did not show any significant difference between SG-added kimchi and control during fermentation. But SG-added kimchi decreased its sensory quality by 5% the other kimch.

  • Danshen (Salvia miltiorrhiza) is a traditional medicinal plant widely used in Asian countries for its pharmacological activities (e.g., amelioration of cardiovascular diseases). In this study, we investigated the anti-atherosclerotic activity of raw danshen root extract prepared using high hydrostatic pressure (HHP) at 550 MPa for 5 min and hot water extraction. This method was useful for elimination of bacteria from cultured danshen plants and for better extraction yield of active principles. The HHP-treated danshen extract (HDE) inhibited proliferation of human umbilical vein endothelial cells (HUVECs) and induced autophagy that was assessed by LC3 conversion and p62 degradation. HDE suppressed foam cell formation in oxLDL-induced RAW264.7 macrophages; lysosomal activity simultaneously increased, measured by acridine orange staining. HDE also reduced atherosclerotic plaque development in vivo in apolipoprotein E knock-out (ApoE-/-) mice fed a high cholesterol diet. Taken together, these results indicated that HDE exhibited anti-atherosclerotic activity via autophagy induction.

  • Candida albicans is an opportunistic human pathogen that causes infections. Candidiasis is often related to antifungal resistance because the pathogen has the ability to form biofilms. In a previous study, we found that the Salvia miltiorriza ethanol extract demonstrated anticandidal activity by altering membrane permeability and inhibiting the cell wall synthesis in C. albicans. Our results here demonstrate that $78{\mu}g/ml$ of the S. miltiorriza extract significantly diminished the early stage biofilms formed by 10 clinical C. albicans isolates by 51.3%; this was analyzed by 2,3-Bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide salt (XTT) reduction assay. The effect of the S. miltiorrhiza extract on the adhesion of C. albicans cells to polystyrene plates and germ tube formation was examined via microscopic investigation. Although the density of the adhered cells was remarkably reduced up on incubation with $39{\mu}g/ml$ S. miltiorrhiza extract, germ tube formation by C. albicans was rarely affected. Quantitative real-time PCR analysis showed that the S. miltiorrhiza extract downregulated the expression of C. albicans hypha-specific genes, EAP1 by 34.7% (p < 0.001), ALS1 by 45.0% (p < 0.001), ALS3 by 48.1% (p < 0.001), and ECE1 by 21.3% (p = 0.006), respectively. Our data suggest that the S. miltiorrhiza ethanol extract significantly inhibited the early stage of biofilm formation by C. albicans by interfering with cell adhesion, by downregulating EAP1, ALS1 and ALS3, and presumably by modifying the cell wall and membrane structure.

  • The kinetics of Ti-transformed Salvia miltiorrhiza cell cultures was studied in 250-$m\ell$ shake flasks by using B5 medium with addition of 30 gfL of sucrose. In the cell cultures, the maximum cell mass obtained was 11.5 g DW/L on day 15. The highest amount of phenolic compounds - rosmarinic acid (RA) and lithospermic acid B (LAB) reached 871.3 mg/L (day 15) and 121.3 mg/L (day 13), respectively. The total tanshinone production, i.e., intracellular plus extracellular cryptotanshinone, tanshinone 1, and tanshinone IIA, was 5.3 mg/L on day 13. For the cultivations in 2.4-L stirred bioreactors, the residual sugar level and medium conductivity were a little higher in a small turbine impeller reactor ($T_s$) than those in a large turbine impeller reactor ($T_L$), while a higher cell density was obtained in the $T_L$. For the production of tanshinones and phenolics, better results were obtained in the $T_L$ than in the $T_s$. In the $T_L$, similar or even a little higher production titers of tanshinones and phenolic compounds were achieved compared to those in the flasks. The results suggest that the shake flask results could be successfully scaled up to the $T_L$ reactor. Such a large impeller reactor like $T_L$ may be better than a small impeller one for the large-scale production of the valuable metabolites by the suspension cultures of Ti transformed S.miltiorrhiza cells. This is considered due to the beneficial culture environment in the $T_L$, such as low shear rates as estimated theoretically.

  • 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.

  • 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.

  • 단삼(丹蔘) (Salvia miltiorrhiza)은 꿀풀과(일과(―科) Lamiaceae)에 속하는 다년생 초본으로, 중국이 원산지이며 약용하기 위해 우리나라에서도 널리 재배하고 있다. 신농본초경(神農本草經) 상품(上品)에 수재(收載)되어 있으며, 거어지통(祛瘀止痛), 양혈소종(凉血消腫), 청심제번(淸心除煩), 활혈조혈(活血調血) 등의 효능이 있어 부인과 질환에 많이 사용되고 있는 약재에 속한다. 본 연구에서는 단삼(丹蔘) 추출물이 흰쥐의 흉부 대동맥 절편에 어떠한 양상으로 작용하는지 확인하고자 하였으며, 그 결과 단삼 추출물 특히 헥산 분획에서 강력한 혈관 이완 작용이 나타났으며, 혈관 내피 세포의 존재 유무에 상관없이 농도 의존적으로 혈관을 이완시켰으나 혈관 내피 세포가 존재하는 상황에서 더욱 강력한 혈관 이완 작용을 보였다. 이러한 과정에 NO에 의한 cGMP 증가가 주요하게 작용하는 것으로 추정되었으며, 칼슘 통로 차단 효과에 의한 세포 내 $Ca^{2+}$의 감소도 관여하는 것으로 생각된다.
