Objective:To study the effect of various extract of Sini Decoction on hypothalamus-pituitary-sexual glands axle of hypothyroidism rats with syndrome of yang deficiency, and discuss the mechanism of Sini Decoction in reinforcing yang. Methods: The model of deficiency of both the spleen-yang and the kidney-yang were induced by PTU solution. After the model were confirmed, the rats in Sini Decoction group were administered with Sini Decoction . At the end of the experiment, all the rats were sacrificed and the blood were sampled to check the level of Sex hormones , the reproductive organs were weighed, the testicle were sliced to check their pathological change. Results:Various extract of Sini Decoction can reduce the increase of weight of orchis and prostate of model rats, reduce their pathologic damage, and increase the level of testosterone. The alcohol extract of Sini Decoction has obvious therapetic effects. Conclusion: Sini Decoction can improve the sexual hormone level and weight index of reproductive organs of hypothyroidism rats with syndrome of yang defi ciency.

OBJECTIVETo investigate the change regularity of ephedrine and glyrihhzine acid in Ephedra sinila and Glycyrrhiza uralencis pair medicines and in Maxing Shigan decoction.

METHODThe contents of ephedrine and glycyrrhizic acid were determined by HPLC in samples of E. sinica extracts, G. uralencis extracts, pair medicines extracts of Maxing Shigao decoction sinica and G. uralencis, and extracts of E. sinica.

RESULTThere were no significant difference in ephedrine contents amoung different samples; the contents of glycyrrhizic acid were lower in decoctions of Maxing Shigan decoction than in G. uralencis decoction and pair medicines extracts.

CONCLUSIONMacromolecular complex was NOT formed by ephedrine and Glycyrrhizic acid in decoctions containing pair medicines of E. sinica and G. uralencis.

OBJECTIVETo determine the change pattern of alkaline and acid components of Dahuang and Fuzi in different combinations.

METHODThe contents of anthraquinones and aconite alkaloids were determined by HPLC in samples of Dahuang extracts, Fuzi extracts, Dahuang and Fuzi pair medicines extracts, and extracts of whole recipe.

RESULTAs for Dahuang, the contents of anthraquinones were decreased with changes of combination: higher contents were in decoctions of Dahuang alone, lower contents were in decoctions of pair medicines, and the lowest contents were in decoctions of whole recipe. As for Fuzi, monoester aconite alkaloids could be detected in water extracts, and both biester and monoester aconite alkaloids could be detected in ethanol extracts. The contents of aconite alkaloids were decreased with changes of combinations: from Fuzi alone to pair medicines, and to whole recipe. The change pattern was more apparent when extracted in water decoction.

CONCLUSIONThe contents of alkaline and acid components are changed with different extract methods and different combinations.

OBJECTIVETo study the chemical structures of macromolecular complexes formed by aconitine and glycyrrhizic acid, aconitine and rhein, berberine and rhein, ephedrine and glycyrrhizic acid in decoctions.

METHODThe binding energy of reactants and products was determined by X-ray spectrography, the ground level charge distribution of products was caculated by density function theory of quantum chemistry.

RESULTThe binding energy of aconitine and glycyrrhizic acid, aconitine and rhein, berberine and rhein were changed after reaction. The characteristic atoms in the molecular structures of acid components have higher positive electric charge, while the ones in alkaline components have higher negative charge.

CONCLUSIONAconitine and glycyrrhizic acid, aconitine and rhein, berberine and rhein can form macromolecular complexes, ephedrine and glycyrrhizic acid can not.

OBJECTIVETo determine the change pattern of alkaline and acid components of Dahuang and Huangbai amoung different combinations in Dahuang Xiaoshi decotion.

METHODThe contents of anthraquinones and berberine were determined by HPLC in samples of Dahuang extracts, Huangbai extracts, Dahuang and Huangbai pair medicine extracts, and extracts of whole recipe.

RESULTThe contents of anthraquinones and berberine were decreased with the changes of combinations: from component medicinal material alone to pair medicines, and to whole recipe. the change pattern was more apparent in water decoctions than in ethanol extracts.

CONCLUSIONThe contents of alkaline and acid components are changed with different extract methods and different combinations.

OBJECTIVETo determine the change pattern of alkaline and acid components of Fuzi and gancao amoung different combinations in Sini Decotion.

METHODThe contents of aconite alkaloids and glycyrrhizic acid were determined by HPLC in samples of Fuzi extracts, gancao extracts, Fuzi and gancao pair medicines extracts, and extracts of whole recipe.

RESULTAs for Fuzi, monoester aconite alkaloids could be detected in water extracts, and both biester and monoester aconite alkaloids could be detected in ethanol extracts. The contents of aconite alkaloids were decreased with changes of combinations: from Fuzi alone to pair medicines, and to whole recipe. The change pattern was more apparent when extracted in water decoction. As for Gancao, the glycyrrhizic acid was lowered from single medicine to pair medicines, and to whole recipe.

CONCLUSIONThe contents of alkaline and acid components were changed with different extract methods and different combinations of Fuzi and Gancao.

Objective To optimize the formula of Dahuang Xiaoshi decoction components based on its hepatoprotective activity and evaluate their efficacy.Methods The Wistar rats were randomly divided into blank group,model group,ursodeoxycholic acid group(positive group),and orthogonal groups of Dahuang Xiaoshi decoction components.The acute liver injury model induced by alpha-napthyl-i sothiocyanate(ANIT)was used to optimize the allocation ratio of Dahuang Xiaoshi decoction components by taking liver function indicators as an index and combining with multiple statistical methods.The additional Wistar rats were taken to induce liver injury and optimize the compatible dosage of Natrii Sulfas(0,1,2,4 g)in Dahuang Xiaoshi decoction components based on the biological signs and liver function biochemical indicators.On this basis,the Wistar rats were randomly divided into blank group,model group,ursodeoxycholic acid group and different dosages(low,medium and high)of the Zhibaihuang components group.The liver protective effect of Zhibaihuang components was systematically evaluated through the general biological signs,liver function biochemical indicators,lipid peroxide indicators,liver pathological examination and bile transport-related indicators.Results Dahuang Xiaoshi decoction components optimized by orthogonal and multiple statistics could improve the biological signs and ameliorate the biochemical abnormalities in rats with liver injury.Dahuang Xiaoshi decoction components combined with different dosages of Natrii Sulfas could slow down the mass loss of ANIT-induced acute liver injury rats(P＜0.01 or P＜0.05)and recall the abnormally elevated serum liver function enzyme activities(P＜0.01 or P＜0.05).Except for alkaline phosphatase(ALP),there was no statistical difference in regulating other liver function enzyme activity between different allocations of Natrii Sulfas.After comprehensive consideration,its composition was optimized to the Zhibaihuang components without Natrii Sulfas.Further pharmacodynamic evaluation results showed that the optimized Zhibaihuang components could improve their abnormal biological signs(P＜0.01 or P＜0.05),decrease the serum liver function enzyme activity(P＜0.01 or P＜0.05)and the levels of T-BiL and TG(P＜0.05),and restore the levels of hepatic lipid peroxide(P＜0.01 or P＜0.05),repair liver pathological injury,adjust the expression of bile transport proteins(P＜0.05),and thus exert good liver protective activity.Conclusion The optimized Dahuang Xiaoshi decoction components,Zhibaihuang components,was obtained through orthogonal,multiple statistics and univariate investigation.It could improve the abnormal biological signs of animals,protect the liver and reduce enzymes,resist lipid peroxidation,restore abnormal metabolic indicators,and repair liver pathological injury,which provides a reference for its further clinical application and development.
