Forty herbal drugs which are described to have potential antitumor activity were solvent-fractionated with petroleum ether, ether and ethyl acetate in sequence. The cytotoxic activity was mostly shown in the ether fraction(40.54%) and petroleum ether fraction (35.15%), but scarcely in the water phase (10.8%), meaning that most of the active components had less polar property. Twenty-seven percent of the drugs tested were active, which is higher value than 10.4% of the random sampled drugs The drugs possessing the $ED_{50}$ values less than $10{mu}g/ml$ were the roots of Lithospermum erythrorhizon, Curcuma domestica, Salvia miltiorrhiza, Astragalus membraneceus and Scutellaria indica, the leaves of Panax ginseng, S. indica and Liriodendron tulipifera, the barks of Picrasma ailanthoides and Rhus vernifera, the herbs of Agrimonia pilosa and Siegesbeckia pubescens the seeds of Tricosanthes kirilowii, P. ailanthoides, and the stem of P. ginseng.

The purpose of this study was to evaluate the osteogenic capacity of water extract of danshen (Salvia miltiorrhiza Bunge). We have established in rat critical-sized calvarial defect model using the combination with collagen scaffold and danshen hydrophilic extract. All rats were extinguished at 8 weeks after bone graft surgery, and the bone regeneration ability of bone grafting sides was evaluated by plain radiography and micro-CT. These results revealed water extract of danshen had the potential to promote osteogenesis especially continuous oral administration with local treatment compared to one-shot local treatment. This compound may provide a new alternative agent for growth factors to promote bone healing and bone regeneration. In conclusion, these results suggest that danshen hydrophilic extract have the potential to promote osteogenesis in bone defects. Further studies about fusion technology with salvianolic acid B, peptides, growth factors, and scaffolds using of the combination of tissue engineering, cell engineering and mechanical engineering are needed.

Previous our study demonstrated that ailanthoidol (3-deformylated 2-arylbenzo[b]furan), a neolignan from Zanthoxylum ailanthoides or Salvia miltiorrhiza Bunge, is a novel anti-inflammatory agent. In this investigation, we examined the anti-adipogenic effect of ailanthoidol. Our data showed that ailanthoidol suppressed lipid droplet formation and adipocyte differentiation in 3T3-L1 cells. Treatment of the 3T3-L1 adipocytes with ailanthoidol resulted in an attenuation of the releases of leptin and interleukin-6. The expression of peroxisome proliferator-activated receptor $(PPAR){\gamma}$ and CCAAT/enhancer-binding protein $(C/EBP){\alpha}$, the central transcriptional regulators of adipogenesis, was decreased by treatment with ailanthoidol. Additionally, ailanthoidol treatment increased the phosphorylation levels of 5' adenosine monophosphate-activated protein kinase. These results suggest that ailanthoidol effectively suppresses adipogenesis and that it exerts its role mainly through the significant down-regulation of $PPAR{\gamma}$ and $C/EBP{\alpha}$ expression. Our findings provide important insights into the mechanisms underlying the anti-adipogenic activity of ailanthoidol.

The effects of four tanshinones isolated from Tanshen (the root of Salvia miltiorrhiza Bunge, Labiatae) were tested for their inhibition of nitric oxide production in macrophage cells, and the underlying molecular mechanisms studied. Of the four tanshinones used, 15, 16-dihydrotanshinone- I, tanshinone-IIA and cryptotanshinone, but not tanshinone I, demonstrated significant inhibition of the LPS-induced nitric oxide production in RAW 264.7 cells, with calculated $IC_{50}$ values of 5, 8, and 1.5 ${\mu}M$ , respectively. Tanshinones exerted inhibitory activities on the LPS-induced nitric oxide production only when applied concurrently with LPS, and tanshinone- IIA and cryptotanshinone were found to inhibit LPS-induced NF-$_KB$ mobilization and extracellular- regulated kinase (ERK) activation, respectively. These results suggest that tanshinones inhibit LPS-induced nitric oxide generation by interfering with the initial stage of LPS-induced expression of certain genes. NF-$_KB$ and ERK could be the molecular targets for tanshinones for the inhibition of LPS-induced nitric oxide production in macrophage cells.

We reported that ailanthoidol, a neolignan from Zanthoxylum ailanthoides and Salvia miltiorrhiza Bunge, inhibited inflammatory reactions by macrophages and protected mice from endotoxin shock. We examined the anti-inflammatory activity of six synthetic ailanthoidol derivatives (compounds 1-6). Among them, compound 4, 2-(4-hydroxyphenyl)-5-(3-hydroxypropenyl)-7-methoxybenzofuran, had the lowest $IC_{50}$ value concerning nitric oxide (NO) release from lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Compound 4 suppressed the generation of prostaglandin (PG) $E_2$ and the expression of inducible NO synthase and cyclooxygenase (COX)-2 induced by LPS, and inhibited the release of LPS-induced pro-inflammatory cytokines from RAW264.7 cells. The underlying mechanism of compound 4 on anti-inflammatory action was correlated with the down-regulation of mitogen-activated protein kinase and activator protein-1 activation. Compound 4 is potentially an effective functional chemical candidate for the prevention of inflammatory diseases.

Protein tyrosine phosphatase 1B(PTP1B) is thought to be a negative regulator in insulin signal-transduction pathway. Insulin-resistance by the activation of PTP1B is a hallmark of both type 2 diabetes and obesity. Thus, the compounds inhibiting PTP1B can improve insulin resistance and can be effective in treating type 2 diabetes and obesity. The methanol extracts of 160 herbal medicines were screened for the inhibitory activity against PTP1B. Among the tested extracts, methanol extracts of Amsonia elliptica, Areca catechu, Benincasa hispida, Morus alba, Salvia miltiorrhiza, Siegesbeckia orientalis, and Trichosanthes kirilowii showed relatively strong inhibitory activity against PTP1B.

Objectives : Consumption of fermented foods has been known to alleviate some of the symptoms of atopy and may limit allergy development, while there are also many medicinal herbs proved to be effective for immunologically-mediated diseases. In this study, we introduced modern zymology to ferment some herbs to see if fermentation has the possibility of increasing the anti-inflammatory effects of medicinal herbs. Interleukin-4 (IL-4) and interferon-gamma $(INF-\gamma)$ have been demonstrated to be the main factors in the pathology of allergic diseases. Methods : We measured the levels of IL-4 and $INF-\gamma$ on concanavalin A-induced BALB/c mice spleen cells, which were subsequently treated with fermented and unfermented herbs. We then compared the fermented groups with unfermented groups to see if the anti-inflammatory effects of the herbs were influenced by fermentation. Results and Conclusions : Our results showed that fermentation had the potential to increase the anti-inflammatory effects of some medicinal herbs, and Astragalus membranaceus and Salvia miltiorrhiza would be the most suitable medicinal herbs for fermentation among the herbs in this study.

Soybean curd residue (SCR), known as a major waste product of soybean processing, is the water-insoluble fraction which is removed by filtration during soymilk production. For these reasons, SCR was usually considered as food waste. SCR might have a good potential as a functional food material, value-added processing and utilization. SCR contains high-quality protein and consists of a good source of nutrients, including protein, oil, dietary fiber, minerals, along with un-specified monosaccharides and oligosaccharides. Also, SCR might be a potential source of low cost protein for human consumption. However, SCR could be a source of bacterial contamination when during food processing. This study was aimed to investigate antibacterial capacity of natural product through detecting relationship between SCR and microbial. We isolated five bacterial strains from SCR and elucidated antibacterial activity of nature medicines to extend storage capacity of food made with SCR. Thus, the extract which showed antibacterial effects in Corynebacterium calloonae and Raoultella amithinolytica is a combination of seven kinds of extracts: Glycyrrhiza uralensis, Cudrania tricuspidata, Salvia miltiorrhiza Bunge, blueberry, Acorus gramineus, Ginkgo biloba L., Camellia sinensis. This study suggested that antibacterial activities of natural medicines could be used for extension of storage capacity in SCR-contained food.
