The Wnt/beta-catenin pathway has a role in osteoblast differentiation and bone formation. We screened 100 plant extracts and identified an extract from Euodia sutchuenensis Dode (ESD) leaf and young branch as an effective activator of the Wnt/beta-catenin pathway. ESD extract increased beta-catenin levels and beta-catenin nuclear accumulation in murine primary osteoblasts. The ESD extract also increased mRNA levels of osteoblast markers, including RUNX2, BMP2 and COL1A1, and enhanced alkaline phosphatase (ALP) activity in murine primary osteoblasts. Both ESD extract-induced beta-catenin increment and ALP activation were abolished by beta-catenin knockdown, confirming that the Wnt/beta-catenin pathway functions in osteoblast differentiation. ESD extract enhanced terminal osteoblast differentiation as shown by staining with Alizarin Red S and significantly increased murine calvarial bone thickness. This study shows that ESD extract stimulates osteoblast differentiation via the Wnt/beta-catenin pathway and enhances murine calvarial bone formation ex vivo.

OBJECTIVETo preliminarily study the effective dosage range and mechanism of the abirritation of volatile oil of Evodia Fructus on the stomach cold syndrome model in mice, and discuss the correlation between its accompanying toxicity and oxidative damage mechanism, in order to provide the experimental basis for explaining the efficacy-syndrome-toxicity correlation.

METHODThe stomach cold-syndrome model in mice was induced by the classic hot plate test by orally administrating with different doses of volatile oil of Evodia Fructus, in order to observe its abirritation and companying toxic and side effects and detect serum ALT, AST, PGE2, NO, NOS, MDA, SOD, GSH, GSH-Px, BUN, CR and hepatic ALT, AST. The companying toxic symptoms in mice were recorded in toxic reaction integral table.

RESULTVolatile oil of Evodia Fructus had an obvious analgesic effect at 30 min after the oral administration and reached the peak effect at 60 min, with certain "dose-effect" and "time-effect" relations, rises in serum and hepatic ALT and AST levels, serum PGE2, MDA, NO and NOS and hepatic indexes, decreases in SOD, GSH and GSH-Px and no notable change in BUN, CR levels and kidney weight/body ratio. Conclusion: The abirritation mechanism of volatile oil of Evodia Fructus was related to the inhibition of pain transmitter release, peroxidative damage and NO damage, which is accompanied by certain hepatotoxicity, mainly mainly oxidative damage, with a concurrent "dose-time-toxicity" relationship.

This study is to develop a HPLC method for quality evaluation of Euodiae Fructus and related species by simultaneous determination limonin, indole alkaloids (14-fomyldihydroxyrutaecarpine, evodiamine, rutaecarpine), and quinolone alkaloids [1-methyl-2-undecyl-4 (1H)-quinolone, evocarpine, dihydroevocarpine] in the fruits of five Evodia species. Samples were analyzed on a YMC C18 column (4.6 mm x 250 mm, 5 microm) eluted with mobile phases of acetonitrile (A), tetrahydrofuran (B), and a buffer solution of 5 mmol x L(-1) ammonium acetate (pH 3.8) (C) in a linear gradient mode. The column temperature was 30 degrees C and the flow rate was 1.0 mL x min(-1). The PDA detector wavelengths were set at 220 and 250 nm. The seven compounds were well separated and showed good linearity (r = 0.999 9) within the concentration ranges tested. The mean recoveries were between 96.7%-102.4% (RSD 1.4%-3.1%). Through the validation, the method was proved to be accurate and repeatable. All the seven constituents were detected in the fruits of five species, but the contents of them varied widely in different samples. The total contents of seven constituents in 16 batches of Euodiae Fructus were 9.46-69.9 mg x g(-1), and the mean content was 28.2 mg x g(-1). The total content of seven constituents in E. compacta and E. fargesii was 25.8, 7.69 mg x g(-1), respectively.

OBJECTIVETo study the metabolism of berberine and palmatine in prescription compatibility of Wuji Wan in human intestinal flora.

METHODThe L9 (3(4)) orthogonal design was adopted to compare prescription compatibility of nine groups of Wuji Wan composed of Coptis chinensis, Evodiae and fried Radix paeoniae alba into and single ingredient of C. chinensis. They were cultivated with fresh human excrements under anaerobic conditions for 24 h. A HPLC-UV method was adopted for determining berberine and palmatine in bacteria culture medium, in order to compare the metabolism of the two components in different prescription compatibility.

RESULTMetabolism of berberine was positively correlated with doses, whereas metabolism of palmatine was negatively correlated with doses in extracts from C. chinensis. Compound compatibility speeded up the metabolism of berberine in low dose, which was positively related to the doses of Evodiae and fried Paeoniae Alba Radix; meanwhile Compound compatibility slowed down the metabolism of berberine in high dose, which was negatively related to the dose of Evodiae. Compound compatibility speeded up the metabolism of palmatine in high dose, which was negatively related to the doses of Evodiae and fried Paeoniae Alba Radix.

CONCLUSIONThe metabolism of the compatibility of Wuji Wan speeds up, when Coptis chinensis components metabolite rapidly in intestinal flora; while the metabolism of the compatibility of Wuji Wan slows down, when C. chinensis components metabolite slowly in intestinal flora. Therefore, they show a balanced effect. Additionally, different proportion of C. chinensis, Evodiae and fried Paeoniae Alba Radix cause difference in metabolism speed of berberine and palmatine to some extent.

OBJECTIVETo discuss the effect of Euodiae Fructus on hepatic energy metabolism-related mechanisms of mitochondria of hepatic tissues of asthenia cold syndrome rats.

METHODRats were subcutaneously injected with Reserpine to establish the model. After the oral administration with Euodiae Fructus for 12 d, the oxygen electrode method was adopted to determine the respiration efficiency. The expressions of Cox4, Atp5b, Ucp2,Pgc-1alpha, Nrf1, Tfam mRNA were assayed by using RT-PCR method.

RESULTEuodiae Fructus 4.2 g x kg(-1) could obviously increase ST3 and RCR of asthenia cold syndrome rats, and expressions of Cox4, Ucp2 Nrf1 mRNA. It could also increase expressions of Atp5b and Pgc-1alpha mRNA, but with no statistical significance. No obvious change was observed in Tfam mRNA expression. Euodiae Fructus 4.2 g x kg(-1) could significantly increase ST3 and RCR of asthenia cold syndrome rats and Pgc-1alpha mRNA and Nrf1 mRNA expressions, and significantly decrease P/O, with no obvious impact on Cox4, AtpSb, Ucp2, Tfam mRNA expressions.

CONCLUSIONEuodiae Fructus can promote mitochondrial respiratory function and oxidative phosphorylation efficiency by improving Pgc-1alpha mRNA and Nrf1 mRNA expressions and regulating Cox4 and Atp5b mRNA in mitochondrial respiratory chain. It can also strengthen mitochondrial uncoupling respiration and add heat production by activating Ucp2 mRNA expression in liver.

OBJECTIVETo evaluate the changes in the concentrations of five components in Fructus Evodiae used in Chinese medicine, including evodiamine and glycyrrhizic acid, during processing of Fructus Evodiae with Radix Glycyrrhizae extract by using high performance liquid chromatography (HPLC) and to provide a scientific basis for different clinical uses of processed and unprocessed Fructus Evodiae.

METHODSThe concentrations of the Fructus Evodiae components in processed or unprocessed Fructus Evodiae were evaluated by HPLC using a YMC J'sphere ODS-H80 column (4.6 mm×250 mm, 5 μm) with acetonitrile-water-tetrahydrofuran-acetic acid (41:59:1:0.2, v/v/v/v) as the mobile phase. The detection wavelength was 225 nm, the column temperature was 35°C, the flow rate was 1.0 mL/min, and the injection volume was 10 μL. The concentrations of the Radix Glycyrrhizae components were determined by HPLC with a Kromasil-C₁₈ column (4.6 mm×250 mm, 4 μm) and a gradient elution of acetonitrile (A) and 0.05% aqueous phosphoric acid (B) as the mobile phase. The detection wavelength was 237 nm, the column temperature was 35 °C, the flow rate was 1.0 mL/min, and the injection volume was 10 μL.

RESULTSThe calibration curves of evodia lactone, evodiamine, rutaecarpine, liquiritin, and glycyrrhizin showed good linear relationships (r>0.99). The recoveries of evodia lactone, evodiamine, rutaecarpine, liquiritin, and glycyrrhizin were 96.59%, 104.18%, 101.91%, 97.75%, and 97.95%, respectively. The concentrations of the components in processed Fructus Evodiae were obviously different to those in unprocessed Fructus Evodiae.

CONCLUSIONSThe developed method is rapid and accurate. The results provide a reference for processed Fructus Evodiae and the changes that could be expected in its effects compared to unprocessed Fructus Evodiae.
