ABSTRACT
Objective To determine content of Salidroside in Ligustri Lucidi Fructus at different growth stages and in different regions in Zhejiang Province by HPLC; To provide the basis for more rational, efficient extraction of Salidroside from Ligustri Lucidi Fructus.Methods The Kromasil C18 column (4.6 mm×150 mm, 5μm) was used with mobile phase of acetonitrile-water (10:90); flow rate was 1.0 mL/min; detection wavelength was 220 nm; column temperature was set at room temperature; injection volume was 20μL.Results Salidroside was in good linear range within 0.71–3.55μg (r=0.999 4). The recovery rate of Salidroside was 95.6%–98.6% and the average recovery rate was 96.88%, RSD was 1.32% (n=5).Conclusion The content of Salidroside in Ligustri Lucidi Fructus gradually decreased with the extending of growing season. The contents of Salidroside were different at different growth stages and in different regions.
ABSTRACT
Objective To study the therapeutic effect of tianluo decoction against hepatitis B virus(HBV) in vivo and vitro.Methods The inhibitive effect were observed in the duplication process of hepatitis B virus by fluorescence quantitative PCR(FQ-PCR) in vitro test and duck's hepatitis B animal model in vivo test.Results FQ-PCR in vitro test demonstrated that tianluo decoction had biological function to inhibit from duplication of hepatitis B virus,and there were significant difference in inhibit hepatitis B virus from duplicating in distilled water and tianluo decoction group(median:6.9?108/ml vs 2.6?104/ml,u=2.76,P
ABSTRACT
Objective To investigate the enhanced effect of polysaccharide from B.jiangsiensis(PBJ) on the immune hypofunction mouse models and its dose-effect relationship.Methods The immune hypofunction mouse models were made by hypodermic injection with cyclophosphamide(Cy) in mice.PBJ's effect on hemolysin content in mouse body induced by chicken erythrocytes and the delayed-type hypersensitivity(DTH) induced by dinitrochlorobenzene in mice were observed and contrasted in the different mouse groups treated with Cy in vivo by hypodermic injection together with PBJ at doses of 400mg/kg,200mg/kg and 50mg/kg,respectively.Results The test showed that the index of hemolysin,hemolytic plaque formation and delayed hypersensitivity reaction in model group markedly decreased while the indexes of hemolysin test in the control group,high and middle dose groups increased(P
ABSTRACT
To observe the protective e ect of oral Liuweidihuang pill combined with Shengmai capsule on heart of primary hypertension with syndrome of de ciency of both qi and yin of heart and kidney.Method:While decreasing blood pressure with Captopril,oral Liuweidihuang pill combined with Shengmai capsule was used to treat 55 cases of primary hypertension,control groups was established.BP,cardiac function,damage degree of myocardial hypertrophy and blood vessel endothelium were detected.Result:ALL the indexes above in treatment group decreased obviously,showed signi cant di erence when compared with control group.Conclusion:Oral Liuweidihuang pill combined with Shengmai capsule and Captopril has cooperative e ect of antihypertension.The combined medication can treat heart damage by reducing myocardial oxygen consumption index,reversing myocardial hypertrophy,improving left ventricular function,protecting blood vessel endothelium,and preventing arteriosclerosis.
