Abstract:
Objective To establish biological detection method for Fuzheng Xiaoji capsule.MethodsTaken Radix astragali,Hedyotis diffusa Willd, Fructus Polygoni orientalis and rhubarb in Fuzheng Xiaoji capsule as targets, the antimicrobial activity of the single fried mixture of Radix astragali,Hedyotis diffusa Willd,Fructus Polygoni orientalis and rhubarb to 4 kinds of standard strains(Staphylococcus aureus, Salmonella, Escherichia coli and Bacillus subtilis) were inspected.The standard curve by susceptible strains of the inhibition zone diameter and logarithm of the concentration was established,and this test also determined the biological potency of different batches of Fuzheng Xiaoji capsule according to the dose-response curve.ResultsThe single fried mixture of Radix astragali,Hedyotis diffusa Willd, Fructus Polygoni orientalis and rhubarb have strong anti-bacterial effect to the above four standard strains.There was a good linear relationship between logarithmic dose and response effect when the concentration in the range of 0.029-0.136g/mL(r=0.9583).ConclusionBiological potency detection method can be combined with traditional analysis methods to control the quality of Fuzheng Xiaoji capsule.
