Abstract:OBJECTIVE:To establish a convolution spectrum method for limit test of para aminobenzole acid(PABA) in procainie hydrochloride injection.METHODS:There were a wavelength range of convolution spectrum from 210 to 330 nm and interval 4 nm.The codomain of three dimensional differential point of convolution spectrum for limit impurity was used as the criterion.RESULTS:The result of this method was in consistent with that of Chinese pharmacopoeia method for five samples.CONCLUSION:The method is simple,sensitive and accurate,suitable for the pharmaceutical impurity limit test.
Keywords:convolution spectrum method  impurity limit test  procaine hydrochloride injection
