ABSTRACT
Objective: To study the antibacterial activity in vitro of Xiyanping injection combined with cefoxitin, cefuroxime, ceftriaxone, cefmenoxime, amikacin, levofloxacin and meropenem against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter bauman.Methods: Minimum inhibitory concentration (MIC) of the 7 kinds of antimicrobial agents used individually or combined with Xiyanping injection on germs were determined respectively on 96 plates by using the agar dilution method and the checkerboard method.Fractional inhibitory concentration index (FICI) was calculated to evaluate the antibacterial activity of Xiyanping injection combined with the 7 kinds of antimicrobial agents in vitro.Results: MIC of Xiyanping injection combined with cefoxitin was the same as that of cefoxitin used individually on escherichia coli.MIC of levofloxacin combined with Xiyanping injection showed no difference with that of levofloxacin used individually on klebsiella pneumoniae.Besides, Xiyanping injection could increase the MIC of the other antimicrobial agents on germs.Conclusion: Xiyanping injection combined with antimicrobial agents on staphylococcus aureus, escherichia coli, klebsiella pneumoniae shows antagonistic and irrelevant relationship.
ABSTRACT
To explore the stability of Shenkang injection respectively in five different solutions to choose the best com-patibility program and improve the rational drug use. Methods:The pH value, insoluble particles and the content of protocatechuic al-dehyde in Shenkang injection were determined after mixed with five solutions. Results:In the 6-hour mixing, the change order of proto-catechuic aldehyde content was 0. 9% sodium chloride injection> 5% fructose injection> 10% invert sugar injection > 5% dextrose injection> 10% glucose injection, especially in 0. 9% sodium chloride injection, the content was decreased by 20%. The number of insoluble particles was increased after the 2-hour mixing except in 10% invert sugar injection solution, and the increase in the four so-lutions was beyond the requirement in the 2010 edition of Chinese Pharmacopoeia, and the number of insoluble particles in 0. 9% sodi-um chloride injection was the highest with the fastest change. During the experimental process, the pH value was stable. Conclusion:The five solutions show influence on stability of Shenkang injection in varying degrees. Shenkang injection in 0. 9% sodium chloride in-jection is the least stable, which should be used with caution in clinics, while invert sugar injection and glucose injection can be the best choice for Shenkang injection and the mixed solution should be used up in 2h.
ABSTRACT
Objective To established a method for the content determination of ginsenoside Rg1 in Yushangling Capsules by HPLC. Methods HPLC was used with the C18 column. The mobile phase was acetonitrile-0.5% phosphoric acid (24∶76). The flow rate was 1.0 mL/min, the column temperature was 25 ℃, and the detection wave was set at 205 nm. Results The calibration curve was linear in the range of 0.05～0.80 ?g. The regression equation was Y =3629375.5X+2517.1, r =0.9998. The average recovery was 100.48% and RSD was 1.59%. Conclusion The method is simple, accurate and suitable for the content determination of ginsenoside Rg1 in Yushangling Capsules.
ABSTRACT
OBJECTIVE: To optimize the extraction technology of Jingzhi guanxin granules.METHODS: The extraction technology of Jingzhi guanxin granules were optimized using shattering extraction with solvent,refluxing extraction and primary extraction with the content of tanshinone ⅡA,salvianolic acid B,paeoniflorin,ferulate and hydroxysafflor yellow A and extraction rate as index.RESULTS: The optimal extraction process was as follows: Jingzhi guanxin powder,6 fold 95% alcohol,extracting for 10 min in the first time,6 fold 60% alcohol,extracting for 10 min in the second,6 fold 20% alcohol,extracting for 10 min in the third.CONCLUSION: Using shattering extraction with solvent for Jingzhi guanxin granules,extraction rate of each constituent are higher than that of primary extraction.This extraction process is simple in operation and save time.
