  • Studies on thin layer chromatography identification of Astragalus Radix and Scutellariae Radix in Biqiaotong granules

    Objective To establish a method for quality control of Astragalus Radix and Scutellariae Radix in Biqiaotong granules and provide basis for the establishment of quality standard. Methods The single-factor test method was used to investigate the factors of thin layer chromatography (TLC) conditions, including different extract method and solvents, developing system, comogemc agents, temperature, humidity, drawing amounts and thin layer boards, and to screen the best TLC conditions of Astragalus Radix and Scutellariae Radix . Results The TLC conditions of Astragalus Radix were used trichloromethane-methanel-water (13:7:2) as developing solvent, separated on silica gel G, heatd under 105℃ until the spots bacame clear. The TLC conditions of Scutellariae Radix were used methylbenzene-ethy acetate- formic acid-methanel (9:3:2:2) as developing solvent, separated on silica gel G, observed after 30 minutes under daylight until the spots were clear. Conclusions The spot features are clear, and with good separating degree, strong specificity, and good repeatability without the inference of negative control. The TLC method is simple, sensitive and accurate, which can be adopted for the quality control of Biqiaotong granules.

  • Causes and precautions of drug dispensing errors in hospital pharmacy

    Objective To analyze the causes of drug dispensing errors and reduce the error rate through scientific precautions, and improve the quality of pharmaceutical service. Methods According to the PDCA cycle, existing problems were found in dispensing between January and June 2013, and the causes were analyzed. Then, from July 2013, strategies were developed to decrease the dispensing error rate. The variation trend of dispensing error rate from January 2013 to June 2017 were observed. Result The dispensing error rate decreased since the beginning of PDCA cycle, from 0.042‰ (the first quarter of 2013) to 0.003‰ (the second quarter of 2017). Conclusion The PDCA cycle is an effective intervention to detect the errors during drug delivery in inpatient pharmacy, which could improve the quality of pharmaceutical service and insure the patients’ safety.

  • Study on Hydrolyzate from Aconitine-type Alkaloids in Monkshoo Decoction of Radix Aconiti

    【摘要】 目的 考察用乌头碱水解物、新乌头碱水解物、次乌头碱水解物的含量作为附片水煎剂及附片质量控制指标的可行性。 方法 采用高效液相色谱分析法,色谱柱为Shimpack CLC-ODS,以甲醇-乙酸铵溶液(0.2 mol/L)(200︰210)为流动相,流速1.0 mL/min,检测波长为241 nm,对乌头碱新,乌头碱、次乌头碱水解物的含量测定进行研究。 结果 3种水解物检测方法测得水解物在进样范围有良好线性关系,重现性好,稳定性好,生药提取时间宜选定为40 min,不同批号的附片中3种水解物含量差别较大。 结论 此方法简便,使用新乌头碱、乌头碱、次乌头碱的水解物作为含附片制剂的质量控制指标是可行的。【Abstract】 Objective To examine the feasibility of regarding the hydrolyzate from aconitine, new aconitine, and hypaconitine to be the decoction of radix aconite and the quality control index.  Methods High performance liquid chromatographic method (HPLC) method was adopted. Shimpack CLC-ODS column with UV detection at 241 nm was used. The mobile phase consisted of (200∶210), and the flow rate was 1.0 mL/min. Results The content of the hydrolysis objects in the water decoction and toxicity were correlated with each other, and the contents of hydrolysis were significantly different among different groups of radix aconiti. Conclusion This method is simple, accurate and effective for content research of hydrolyzate from aconitine-type alkaloids in Monkshoo decoction of Radix Aconiti, and it is feasible to take it as the quality control index.
