Abstract(2776) PDF (627KB)(943)
Abstract:
Objective: To build up a fast determination method for undeclared prescription drugs in Chinese herbal medicines by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Methods: Multiple reaction monitoring (MRM) mode was employed for the analysis of ten possible prescription drugs, including glibenclamide, sibutramine, etc, in 36 Chinese herbal medicines which were categorized into antidiabetics, antihypertensives, aphrodisiacs, weight reducers, and others, according to pharmaceutical functions. Results: Four antidiabetics (containing glibenclamide), one aphrodisiac (containing sildenafil) and two weight reducers (containing sibutramine) were detected within 10min even without thorough chromatographic separation. Conclusion: LC-MS/MS with MRM mode guaranteed sufficient specificity for qualitative analysis and sensitivity for quantitative analysis, providing an alternative for the rapid analysis of multiple undeclared prescription drugs in Chinese herbal medicines.

Abstract:
Objective: To select optimal diameter of the powder of Radix Astragali and extraction method by four methods of extracting astragalus polysaccharide and total astragalus saponins in three Radix Astragali powders of different diameter. Methods: The water-alcohol co-distillation, cellulose degradation technology, calcarea solution technology, ultrasonic waves technology were used to three Radix Astragali powders of different diameter respectively.The astragalus polysaccharide and total astragalus saponins were separated with combined techniques hollow fiber membrane and D21 macro absorbing resin. According to the contents of astragalus polysaccharide and total astragalus saponins,the extraction methods were compared. Results: The most effective way of extracting astragalus polysaccharide was the ultrasonic waves technology with the yield rate of 1.73%, while the most effective method of distilling total astragalus saponins was ultrasonic waves technology on prepared slice of herbal drug, with the yield of 1.82. Conclusion: Ultrasonic waves technology was a much better way of extracting both astragalus polysaccharide and total astragalus saponins. The shorter the diameter of Radix Astragali powder, the higher the yield of extracting astragalus polysaccharide. The yield of extracting total astragalus saponins turned out contray.

Abstract:
Objective: To investigate the effects of Dehydrocavidine (YHL-DC) on carbon tetrachloride (CCl4) induced acute liver injury in mice. Methods: The mice were pre-treatment with YHL-DC prior to the administration of CCl4 and post-treatment with YHL-DC after the administration of CCl4, and the changes of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBIL) in these mice were examined respectively. Histopathology changes of liver were also observed under both light and electron microscope. Results: Pre-treatment and post-treatment with YHL-DC significantly prevented increase in serum enzymatic activities of ALT, AST and TBIL in a dose-dependent manner. Hepatocyte degeneration and necrosis, infiltration of inflammatory cells and destruction of hepatocyte ultrastructure appeared in carbon tetrachloride induced acute injured liver in mice, while extenuations were observed in both pre-and post-treatment groups administered with YHL-DC. Conclusion: The results suggest that YHL-DC has a potent hepatoprotective action on CCl4 induced acute liver injury in mice.

Abstract:
Objective: To establish a new method for the determination of rabeprazole. Methods: Anodic adsorptive voltammetry with a carbon paste electeode(CPE) was used. Rabeprazole was concentrated on the electrode and determined by adsorptive voltammetry in supporting solution of 1.8 mol/L H2SO4. Results: The anthodic peak potential of raberazole was at 0.498 V(vs.SCE). The peak currents were linear with the concentration of rabeprazole over the range of 4.15×10-7~3.73×10--6mol/L, with the detection limit 6.705×10--11 mol/L. Conclusion: This method is suitable for the determination of rabeprazole, and it is covenient and accurate.
