Abstract: Objective: To establish a method for the content determination of NFH in NFH-13-cyclodextrin inclusion compound. Methods: The drug concentration in NFH-β-eyelodextrin inclusion compound was detected at the wavelength of 267 nm by UV spectro- photometry.The free NFH was eluated by eetoaeetate.The enveloped NFH and its entrapment efficiency were detected by UV spectro- photometry. Results: The linear range of NFH was O.01~0.4 mg/mL (r=0.999 5,n=9);the within day RSD and between-day were 0.17% and 1.82% (u=5),respectively.The average recovery was 100.39% (n=9).The entrapment efficiencies of 3 batches of samples were 73.28%,70.37%,74.97%. Conclusion:: The method is simple and reliable,which can be used for the content determi- nation of NFH in NFH-β-cyclodextrin inclusion compound.
