Abstract:
Objective To study the quality control methods for dragon's blood spraying film agent. Methods The pH value and viscosity of dragon's blood spraying film agent were detected. Drug dispersed homogeneous degree and particle sizes were determined with Nano Particle Size Analyzer and microscope. Content of Loureirin B was measured by Ultra Performance Liquid-Chromtography (UPLC). UPLC was performed on Waters C18 column (2. 1 mm×100 mm,1. 7 μm), the wavelength was 280 nm, the column temperature was 40 ℃ , and the mobile phase was 0. 1% formic acid aqueous solution and acetonitrile, and the flow rate was 0. 8 mL·min-1 . Results The pH value and viscosity of dragon's blood spraying film agent were stable, drug dispersion was homogeneous, and particle size of the drug was tiny. The concentration of Loureirin B had a good linear relationship in the range of 15. 51-77. 54 μg. Conclusion This method can be accurately controlled, has good stability and repeatability, and can fully control quality of dragon's blood spraying film agent.
