| Abstract: | Objective: UV spectrophotometry can be applied to determination of active components in nysfungin.Method: Ethyl ether is used as extract ancillary agent.The nysfungin is solvated by DMF.then dilute it with 5%DMF solution.Detection wavelength of 306nm was specified.Results: A methodological survey pointed out there is a good linearity between 21 to 76 of nysfungin units perml.The corresponding average recovery is 98.8%(n=6).inclusion: The method was found to be simple,quick and accurate for determination of nysfungin in its suppositories. |
