标准测定

Methods: The specifications of ultraviolet-visible spectrophotometers wereaffirmed to ensure that they can meet the requirements of the reference method, andthe reference measurement procedure was established. According to the guidelines ofmethodology validation in ICH and AOAC, we chose the selectivity, linearity,precision and accuracy to evaluate. The linearity and precision were validatedaccording to NCCLS EP6-P2 and EP5-A.

The methods of IR and others were carried on in order toverify the structural formula of XN. The validation of analytical procedures wasconducted according to quality standard of XN in supplement of ChinesePharmacopoeia in 2002. The results show that the structural formula of XN isright and XN can be analysed in accordance with the quality specification of ChP.The results of three lots repeat tests show that the optimal process for XN wasrepeated excellently and quality of products is stable and controllable.
